After a few moments Rainbow Dash started to hear hoofsteps, a lot of hoofsteps. Voices soon started to filter through and then she felt something wet dripping onto her fur and a cool breeze. She opened her eyes to find she was now in the middle of a busy city center. Ponies were walking all around her, seemingly in a hurry to get where they were going and get out of what appeared to be the start of a rain shower.

It took a few moments for her to come around, but once she did Rainbow Dash noticed two things; One that almost all of the ponies in the city center appeared to be unicorns, and two that everypony seemed a lot bigger than she was.

“Are you okay?” A voice asked from behind Rainbow Dash.

The filly turned her head to see a mare towering over her. “I uh. . . where am I?”

Frowning the mare looked around to try and see if anypony around looked like they could be her mother. “You’re in Canterlot sweetie. Where are your parents? They must be worried sick about you.”

Confused, Dash stood up onto her hooves and looked back at her body, not only was she much smaller than she had remembered, but her wings seemed adolescent as well and her cutie mark was missing. “Parents?”

“Oh sweetie. . . I’m sorry. . .” She said to the filly. “Do you have a home?”

Rainbow Dash nodded. “Yeah? Why are you sorry?” She asked, tilting her head.

“Where do you live, I’m going to take you home so whoever cares for you isn’t worried sick.” She said, lighting up her horn and lifting the filly onto her back.

“Wh-what? Let me go!” Dash exclaimed, her wings flaring out as she leapt off of the mare’s back and onto the ground. Trying to run away from the mare, Dash’s galloping was stopped by the mare’s magic enveloping the filly’s tail.

“Sweetie I won’t let you run off, I have to know where you live so I can take you back there.” The mare said, lifting Dash back onto her back, this time her magic staying in place to keep the filly from jumping off. “Do you know where home is?”

Rainbow Dash simply huffed as she was held in place. Thinking that perhaps be being uncooperative the mare might let her go.

Giving a sigh the mare spoke again. “If you don’t know where home is, is there somepony I can take you to?”

Shaking her head, Dash still refused to cooperate.

The unicorn frowned and facehoofed. “Sweetheart I can’t help you if you won’t answer me.”

“I don’t want your help!” The filly said in an aggravated tone.

“I’m not going to leave you out here alone, it’s too cold and wet here. Celestia will be raising the moon soon and it will get even more cold I-”

“Celestia raising the moon? Why isn’t Princess Luna doing it?” Dash asked, cutting the mare off mid sentence.

“Sweetie that’s just a story mommies and daddies tell their foals so they go to bed on time, Princess Luna never really existed and the mare in the moon is just an illusion.”

“Mare in the moon? The mare in the moon hasn’t been there since Nightmare Moon came back and was defeated!” Rainbow Dash protested.

“Nightmare Moon is a silly old ponies tale. Now can you please tell me your name at least?”

With a sigh Dash opened her mouth. “Rainbow Dash.”

“That’s a start, now where can I take you sweetie?” The mare asked, “Canterlot is a very big city after all!”

“Fiiine. . . If you insist on ‘helping’ me, take me to the Royal Palace to see Celestia.” Dash said with a huff.

Facehoofing the mare sighed heavily, getting more irritated by the second, “Come along now, the Guards can help you find your parents.”

“The guards?!” Dash said with a voice crack. Her new, or rather old filly voice working against her cool factor, “They won’t be able to ‘help’ me either!” She protested, knowing she had to find a way to Twilight, Celestia, or somepony else she knew that could help her get back to normal, and the Guards weren’t it.

“Well you’ve left me no choice.” The mare said before trotting off to the nearest Guard station with Dash in tow on her back.

*****

“Next.” A white coated unicorn stallion said from his position behind a desk. A line of ponies moving forward, each of them with different reasons for being there from complaints to other judicial business.

“I found this filly a few blocks away by the fountain, she refuses to tell me where her parents are. She said her name is Rainbow Dash, could you look at the records for her guardians?”

Looking over the desk, the stallion could see the small cyan pony on the mare’s back. He lifted a book out from a shelf behind him using his magic, flipping through it for several moments before closing it. “There’s no record of a Rainbow Dash in the Canterlot city census, let me check the missing pony reports.” He said, lifting another book out from a different shelf, skimming through that one for pegasus ponies matching the filly’s description. “Nothing.”

“Well maybe she’s not telling us her real name. Is your name really Rainbow Dash little filly?”

Frowning at the mare Dash replied. “I have no reason to lie to you.” She said huffing.

“Well that may be so, but in the meantime while we confirm your identity little one, there’s a nice stallion who would like to talk to you.” The guard said before using his magic to ring a bell on the first door of the hallway behind his desk. A brown coated stallion emerging from the room. “There’s a filly here I need you to speak to Subtle Inquisit, there’s no record of her.” The first stallion said with a pause. “You can leave her here with us miss, she’ll be home before you can blink.”

“I’m sure I’ll be able to find something out. Come along little filly I think they have some cookies in the break room you’d like.”

Rainbow sighed as she was lowered onto the ground next to this stallion. “I don’t want to.” She said in a rather foalish tone unintentionally. “I want to go.”

“We’ll make sure you get home once we’re sure where it is.” He said nodding to Dash then looking over at the mare that had brought her in. “Thank you for bringing her into the station Ma’am.” He smiled then trotted out towards the back of the stationhouse. “So how’d you wind up all alone in the middle of Canterlot miss. . .?”

“Rainbow Dash.” She said knowing nopony had told him her name yet. “And magic.”

“You wouldn’t believe how many times we get that answer. . .”

“I’m sure you hear it every day. . .” Dash said rolling her eyes. “Look, I get you all want to ‘help’ me but I don’t need your help, so why don’tcha just let me go and I’ll make my way home by myself.” She said, a bit irritated now that all of these ponies want to help her like she’s some kind of foal. “Oh. . . um before I go though. . . what year is it?”

“The Year of Tigris.”

“The year of Tigris. . . that was almost fifteen years ago. . .” Dash mumbled to herself. “I uh. . . I mean. . .” She paused. ‘Where was Twilight fifteen years ago. . .’ “Do you know where the Sparkle house is?

“We’ll have it on record. Is your family there?”

“Uh. . . Yeah. . . Sure that works! My family is there, uh. . . Their daughter is my best friend and I’m staying with them here in Canterlot. . . Cause obviously I don’t live here, pegasus and all. . .” She said, giving a big smile, hoping to convince him.

“Can you name the ponies that live there?”

“Uh. . .” Dash paused. ‘Let’s see. . . I know Shining Armor. . . What’s her Dad’s name. . . Is Twilight Velvet right? I remember telling myself to remember a name of a cake for one of her relatives names. . .’ The filly thought to herself. “Uh, Twilight Sparkle. . . Twi’s Dad, Twilight. . . Velvet?” She paused. “And Shining Cadenza. . . I think.”

“I’ll go look it up, you sure you don’t want a snack before I go? I can hear your stomach growling at you.”

The cyan filly felt her stomach grumble. She sighed. “I’ll take the cookies. . .”

“Alright no allergies right?” The stallion asked as he reached up to pull a box of cookies down, placing some on a plate for her.

“Only to not being awesome.” She said, taking the plate of cookies and starting to eat them.

“Well I’ll be back before you can finish your snack.” He chuckled trotting away.

Rainbow Dash considered trying to escape while the guard left her alone, but she thought better of it seeing as there were other guards in the break room. The filly climbed up onto a chair after setting her cookies down at a table. Just as she went to reach for a cookie she felt the seat below her grow a little damp. ‘No. . . Twilight said I was physically who I was when I was four or five. I wasn’t potty trained yet. . . No I am still me in my brain! I should be able to know when I have to go. . . feel it and stop it! That can’t be right!’ She thought to herself. Although she was still there mentally, her body had regressed, as had some of her motor control and emotions. After coming to the realization that she wasn’t in control of that part of her body anymore, the filly’s regressed emotions took over and her eyes watered up as she started to cry.

Subtle Inquisit returned a few moments later carrying a few documents in front of him, reading as he walked. He set the documents down on the table and noticed that the filly was crying, “What’s wrong Rainbow Dash? Did you hurt yourself while I was gone, or drop your cookie on the ground?” Subtle asked glancing down at the filly and frowning.

Shaking her head Dash frowned, rubbing her teary eyes with her forehooves. “N-nothing is w-wrong!” She said, trying to fight the urge to cry but her now adolescent body and emotions resisting.

The stallion thought in silence for a few moments, “Did you have an accident?” He asked noticing the small dark spot on the filly’s wooden chair. “It’s okay, you’re only what, five maybe six?”

Sniffling, the filly locked her gaze on the floor, her embarrassment clear on her face as her cheeks turned red. “F-five now. . .” She said quietly, counting back fifteen years. “O-or four. . . I don’t know. . .”

A teal coloured glow surrounded the pegasus filly, lifting her onto the stallion’s back. “Nothing to be upset about at all, Miss Sunflower Dream’s will take care of you until we figure out where you’re going to be staying. She might even find you a few toys to play with while you wait.” He added hoping to cheer up the filly a little bit. They walked through the busy corridors of the guard post before arriving at an office that was considerably more prim and proper than the others they had passed. The stallion knocked twice before entering, he smiled at the mare.

“Can I help you Inquisi-” She started, stopping when she noticed the pegasus filly on her boss’s back. “Aw, is some filly lost?” Sunflower asked, picking up Dash then setting her down on a cushioned chair behind her desk.

“I’m n-not lost!” Dash protested, still sniffling and rubbing her tear filled eyes. She shifted as she was placed on the chair, her wet fur soaking a little bit into the cushion.

“Are you potty trained dear?” She asked ruffling the filly’s mane, offering her a leftover a candy cane from Hearthswarming a few weeks before. “I’ll take care of it from here Inquisit, foals usually love me.” Sunflower said, waving a hoof in a dismissive gesture at the other pony.

The filly was about to say yes to the first question, but thought better of it thinking that it might be less humiliating to just say no and be done with it. “N-no. . . I guess not. . .” She said dejected, taking the candy cane and nibbling on it.

“I didn’t think so, silly filly or fluffy cloud?” The pegasus mare asked, rummaging around in the closet labeled foal supplies. “You’re pretty small sweetie, have you been eating enough?” She asked as an afterthought once the diapers were on the desk for the filly to pick out.

Dash frowned; In honesty she didn’t remember what she wore when she was a foal, only memories of being in diapers until she was six due to consistent hospital stays from ‘trying to be cool.’ “I. . . I don’t know. . .” She said with another frown as she tried to remember her foalhood; Although she considered her foalhood a good one, she looked upon her decisions in the past with regret, wishing she hadn’t been so foolish as to throw such a great time away with hospital stays.

“You look like a silly filly kind of girl.” Sunflower Dream’s smiled, gently pushing the filly down so she could put the absorbent garment onto her. “Lift your butt up~”

The filly complied, blushing as she was getting diapered by a strange mare, something she hadn’t experienced in a long time.

Noticing that the filly seemed a little embarrassed about her wet coat, she grabbed a few foalwipes and cleaned Dash’s coat and unmentionables a few times. “Where did you put your old diaper?” Sunflower asked, taping the diaper on snugly after threading the filly’s tail through the hole.

“Uh. . .” Dash said, still blushing about this whole ordeal. “I dunno. . . I just woke up in the middle of Canterlot . . I uh. . . don’t know how I got here.” She lied, knowing full well how she got here but also knowing that they would never believe her if she told the truth and put it off as having an ‘overactive imagination,’ that she very much had as a foal.

“Hmm, I’m sure the big scary stallion already asked, but do you have any cousins or aunts or uncles here in Canterlot? Does anypony know where you are?” The mare asked starting to suspect the filly had been kidnapped.

Dash hesitated for a moment before nodding. “Uhm. . . y-yeah, I’m staying with a friend, I was on my way there! Cause I’m uh. . . taking a course at the magic school on weather! Yeah, that’s what I said earlier and I’m sticking to it!” She said with a rather convincing smile. “Though right now I don’t think anypony knows where I am. . .”

“You shouldn’t have been out wandering Canterlot alone, Rainbow Dash.” Sunflower scolded, “Especially so close to sundown. A cute little filly like you could get foalnapped!” She exclaimed, flaring her wings out at the filly hoping to make her giggle. The mare couldn’t help but notice Rainbow was thin for a foal her age, most foals were quite a bit larger than her.

“I won’t get foalnapped! I’m smarter than that!” Dash said defensively, flaring her own wings out with a slight hint of aggravation. “I’m not that dumb!”

Chuckling Sunflower pulled her wings back to her side. “Have you been eating enough? You didn’t answer me when I asked you earlier. If you’re hungry I could take you to a nice restaurant just down the road, they serve the best oatcakes you’ll ever eat!”

Rainbow Dash let out a sigh. “I eat just fine. . . it’s cause I get hurt a lot. . .” The filly explained. “Daddy says I should be more careful but I’d rather be awesome.” She said, mentally asking herself where the foal in that sentence came from.

“Well do awesome fillies like oatcakes and apple cider?” The mare asked rummaging around in the supply closet for a diaperbag. “I think it would be pretty awesome if you did.” She added, laying on the awesome a little too thick.

With another sigh Dash gave a slow nod of agreement. “I guess. . .”

“Well look on the brightside! Maybe we’ll see your friend there.” Sunflower said nestling the filly between her wings, encouraging her to get comfortable and relax. “You just need to relax Dash, we’re both mares. It’ll be just like a girls night out, your Mommy has those right?”

Rainbow Dash suddenly went quiet, the concept of her mother being alive still suddenly filling her mind. From her perspective, her mother had died eleven years prior in a Wonderbolts airshow after a stray hurricane broke free from the weather facility. The filly’s eyes started to water up again at the thought of possibly being able to see her mother alive again.

“Hey now, don’t cry! I’ll make sure we find your family. Plus you’re getting oatcakes, with all the syrup you want on them.” Sunflower comforted Rainbow to the best of her abilities, not fully understanding why she was upset to begin with. The mare and foal left the guard outpost, Sunflower telling her colleagues where to find her in the event Rainbow’s parents came looking for her.

It took a few moments for Rainbow Dash to stop crying, she wiped her eyes clear and the reality of the current situation started to sink in; She was outside wearing a diaper and openly being treated like a foal, her cheeks turned red in embarrassment as she started to tug on Sunflower’s wings to try and hide herself.

“You know I thought a filly like you, wouldn’t be so shy. You warmed up to me pretty fast, am I just that good with foals?” Sunflower stated, sounding rather full of herself and just a little cocky. Even though she was in charge of lost foals, she still worried she would accidentally hurt one if she wasn’t careful enough.

“I’m not shy!” Dash nearly yelled in protest. “J-just. . . e-everything is different. . .” She trembled, her new perspective of everything being larger, not to mention the different buildings and such from fifteen years ago making her feel uncomfortable.

“Well it looks different because they’re not all made of clouds.” The mare explained, referring to the buildings as they walked. “You’re not much of a walker are you?”

Shaking her head the cyan filly replied. “Not really, I prefer to fly!” She paused after saying that, realizing that at this age, she ‘fell with style’ rather than flew. “O-or try to. . .”

The two ponies entered a grubby looking diner, the decor of the place not matching the exterior of the building. Sunflower winked at Rainbow Dash, “I know what you’re thinking, ‘How come this place looks all dirty on the outside?’ Well little filly I-”

“Don’t give away my secrets, Sunflower.” A blue unicorn stallion said, presenting the two ponies a menu. “Would you like a colouring book miss?” He asked leading them to a table near the back of the spacious restaurant, making sure to grab a high chair for the young filly with Sunflower.

“Always!” Dash’s mind answered for her before she was able to think. “Er. . . uh. . . y-yeah. . .” She said, blushing at her adolescent outburst. ‘I wish whatever Twilight did to me didn’t make me speak without my permission first!’ The filly thought to herself.

Smiling the stallion lifted the foal from Sunflower’s back and strapped her into the chair. “Princesses or animals?” He asked retrieving a box of crayons for Rainbow Dash along with the two colouring books.

“Princesses!” The cyan pegasus mentally kicked herself, her mind once again making an outburst. She gave a quiet, inaudible groan remembering how she used to be into all of the frilly fru fru stuff when she was younger.

“Thanks Astral Blaze, we’ll have the Oatcakes special. No hard cider for me tonight, I’m on the clock still. What about you Rainbow?”

“Pfft! I’ll take some of that hard cider!” The filly replied, idly starting to colour in her colouring book, blushing a bit at the sound of her diaper crinkling under her at every slight movement.

Astral couldn’t help but laugh loudly at the filly’s request, “Sure thing sweetheart, I’ll be right back with a tall glass of cider for you, and a cup of coffee for your big friend.” He winked slyly at Sunflower, subtly informing her he wasn’t giving a foal alcohol. After several minutes, the stallion returned carrying a steaming mug of cider, and coffee. “Make sure your diaper is dry before drinking this, cider goes right through little ponies.” He teased, taking their orders and leaving them alone to bring their order to the kitchen.

Rainbow Dash worried for a moment that her diaper might actually be wet, she shifted her weight slightly and let out a sigh of relief to find that she wasn’t. “I’m n-not. . .” She replied quietly with a small squeak.

“Not what?” Sunflower asked sipping on the bitter brew, smiling at Dash.

“N-not wet. . .” The filly said with another voice crack. “I’m dry.” She blushed several shades of red for having to inform everypony around her of the state of her diaper.

“Well I’d know if you were wet anyways sweetie, those flowers change colours when you’re wet.” The mare explained, looking at the messily coloured pages of Dash’s book. “Do you want some help colouring in that big book?”

Blushing Dash nodded. “I c-can colour inside the lines! I j-just choose not to. . .” She said, knowing fully well that her colouring skills, even now, weren’t very good.

Sunflower chuckled and joined the filly in colouring in the large book, taking extra care to show Rainbow how to colour in the lines, “See if you colour from the outside to the inside, you’ll stay in the lines a lot more often.” She explained showing the filly an expertly coloured picture of Princess Celestia.

Huffing, the filly crossed her forelegs. “I know how to colour!” She said in an aggravated tone.

“I never said you didn’t, but you looked like you were having a little trouble. Do you know how to spell your name Rainbow Dash?” The mare asked watching the filly colour in the book some more, while sipping on her coffee.

“Of course I can! I can spell a lot of things. . .” She said, moving her crayon up to the top of the page to try and spell her name. Rainbow concentrated hard as she spelled her name, smiling at the result. “See!” She said, pointing to her work. ‘Rzduqw Dash’

“Well you got part of it right, you were trying really hard too!” Sunflower reassured the filly, patting her on the head with a wing.

“I got all of it right!” Rainbow Dash protested, looking down at her work, then frowning, realizing that something didn’t look right, but she couldn’t place what it was. ‘Did. . . did Twilight’s spell prevent me from being able to write? I can’t even read most of the words in this colouring book. . .’ She thought to herself, realizing that her concept of spelling seemed to be blocked out, it was still there, just blocked out.

“You’re a smart filly, but you need to work on your spelling and reading it looks like. Are you enjoying your big pony drink?” The mare inquired, pointing at the half drank mug of cider Dash had been nursing on for the last several minutes. She finished her coffee and flagged a waitress down to bring her another cup.

The cyan filly gave another small huff at Sunflower’s comments on her writing. “It’s good.” She replied, taking another sip of her cider, making a mess of it by letting it drip down her muzzle and spill out of the cup every time she took a sip.

Astral Blaze returned carrying a steaming tray of oatcakes, and another mug of cider for the pegasus filly seated at the table. “This is from the kitchen staff Miss, they thought you were super cute! So they wanted to give you another treat.” He explained setting the large mug in front of her.

“I’m not cute!” Rainbow Dash protested, blushing as she took the new mug and started to drink from it, setting the old mug aside as it only had a little bit of cider left in it. “I’m awesome! There is a difference!”

“Uh-huh, make sure you eat all your oat cakes, you’ll grow up to be big and strong if you do!” The stallion said setting the platter down between the mare and filly, he bowed at the pair before taking his leave, causing Rainbow Dash and Sunflower Dream’s to both laugh heartily.

“I wish ponies would stop treating me like I was four. . .” The filly idly thought aloud after the stallion left.

“Well just how old are you then?” Sunflower asked, interrupting Rainbow’s thought process. She sliced up the oatcakes for the both of them to munch on.

“Four.” Dash’s young mind answered for her before she could say anything else, mentally she kicked herself again. “I guess I’m four. . .” She groaned quietly to herself as she started to eat her oatcakes, getting the syrup all over her muzzle and forehooves, somehow managing to get a strand of syrup connected to her left ear and in her mane.

“Here let me help!” The pegasus mare exclaimed, wiping Rainbow’s muzzle and hooves clean with a foal wipe she had retrieved from the diaper bag at her rear hooves. “Just sit still a moment and you can continue to eat, you’ll be all sticky if I don’t clean you up.”

Rainbow Dash of course protested this action by squirming about in her high chair as Sunflower attempted to wipe her clean. “I’m clean! I’m clean! I’m not all sticky!” She continued to protest.

“Well you’re not all sticky anymore.” Sunflower said happily, she waited for the foal to go back to eating before slipping a hoof below the table to feel the outside of her diaper. “Huh still all dry in there. Or at least you feel dry.” She explained as she felt the diaper again, still not feeling any outward signs of wetness or other contents.

Blushing the filly gave a small squirm as she felt the mare check her diaper. “H-hay!” She cried out at what she felt was a violation of her personal space. Before she had time to protest however, a hissing noise filled the immediate area and her face turned several darker shades of red as she felt her diaper growing warm and wet.

“Well you finish eating and then we’ll deal with that, okay?” The mare asked watching the foal devour her oatcakes, it seemed to her that the foal wasn’t very pleased about wetting herself like that. “It’s nothing to be upset about, little ponies have to wear diapers for that reason.” She explained further in a motherly tone. Taking care of lost foals had certainly made her a little motherly.

“Y-yeah. . . I g-guess but it feels weird!” Rainbow Dash said, her muzzle still a deep shade of red. She shifted her weight on her haunches, the diaper squishing with each movement causing her even more embarrassment.

After the two ponies finished their meal, Sunflower took the filly into the bathroom to change her diaper. “There anything else in here I should know about?” She asked lifting Dash onto the fold out changing table, strapping the filly down so she wouldn’t roll off.

The younger pegasus struggled as she was strapped into place, thoroughly not enjoying this treatment or what was about to come. “What’s that suppose to mean?” Dash asked with another small struggle.

“Well I was trying to ask politely if you’re… You know.” The mare gestured vaguely, confusing the foal even more.

“If I’m what?” Rainbow tilted her head in confusion, her face still one of aggravation.

Facehoofing, Sunflower groaned, “If you’re messy, you know, dirty. Down there.” She blurted, mentally preparing herself for the worst. She took a few deep breaths and then released the tab’s on the filly’s diaper, folding down the front and getting to work with a foalwipe. “The less you struggle the quicker this can be done and over with.” She cooed softly, wiping the filly’s genitals until they were clean of the urine. Balling up the dirty wipe, Sunflower began sprinkling foal powder onto Dash’s lower half, being careful not to surprise the foal with anymore touching than was necessary.

Crossing her forehooves, Rainbow continued to struggle throughout the entire process. As if being diapered and made to use them wasn’t bad enough, the changing was demeaning as well to her.

“Somepony doesn’t like their diaper being changed~” The mare sang, sliding a fresh diaper underneath of the pegasus filly. She pulled the front of it up around Rainbow Dash, and expertly taped it on, adjusting the tabs a few times until the fit was just right. “See? Told you it wasn’t so bad.” Sunflower stated chuckling, she tossed the wet diaper into a nearby trashbin and washed her hooves in the sink. “Ready to help me find your friend?”

The cyan filly huffed at Sunflower. “Fine.”

“Can you tell me what your friend’s Mom looks like?” Sunflower inquired setting Rainbow Dash down on a sofa in her living room.

“Uh. . . she’s got a white coat and I think she has a purple mane. . .” Dash explained as she tried to remember what Twilight’s mother looked like. “Though. . . I think she might be with her foalsitter. . .” She said, thinking back to all of the times Twilight mentioned Cadance.

“Well who’s her foalsitter? Anypony I’d know?”

Taking a breath, Dash decided to say it, even if Sunflower probably wouldn’t believe her. “Princess Cadance.”

Blinking a few times, Sunflower let the filly’s words sink in. “Well I suppose she is only a teenager. She shouldn’t be too hard to find, I bet if we wrote a letter to the castle, requesting an audience with her, we’d be able to find her pretty quickly-”

Rainbow cut the mare off mid sentence. “Why not just go to my friends house. . . she’s probably there, Cadance and Twilight’s older brother have crushes on each other, so I’m willing to bet Cadance is at their place.” She said.

“Do you know where your friend lives though sweetie?” The mare asked giggling at Rainbow.

“Good point. . .” Dash said with a sigh. “Why don’t we have that pony at the guard station look in his big book for where they live?”

“That’s not a bad idea, lets go then. I don’t think you want to spend the night with me anyways.” Sunflower said laughing, she picked up the filly and placed her between her wings.

“Not at all. I don’t even know you.” The cyan pegasus said as she was picked up, frowning at the crinkling of her padding.

The two ponies left the small apartment and quickly made their way to the guard headquarters. Once inside Sunflower asked the unicorn guard on duty to look up the address of a foal named, “What was your friend’s name again?”

“Twilight Sparkle.” Rainbow Dash said.

“Lets see. . . Twilight Sparkle.” The unicorn said, lifting a pair of glasses to his eyes and a large, magical book to the desk in front of him. “Shine, Spade, Sparkle! Here it is, Twilight Sparkle, One twenty two Hooftrot Way, that’s not too far from here either.”

Sunflower sighed in relief, “Thank Celestia!” She muttered under her breath. “Let’s take you to your friend’s house then.” She said winking at the filly.

“It’s about time!” The pegasus on Sunflower’s back said. “It’s getting dark and scary outside.” The foal in her mind said.

“I didn’t think a tough little filly like you, was afraid of the dark.” The mare smirked, trotting along the well lit street’s of Canterlot.

“I’m not afraid of the dark!” Rainbow protested, using both Sunflower’s wings and her own wings to try and make a shield around herself to keep the scary darkness out.

Chuckling a few times as they walked, Sunflower arrived at the modest sized house. Though they were in a posh part of Canterlot the house in question was significantly smaller than their neighbours. The sound’s of fillyish laughter could be heard through the front door. The mare knocked on the front door, the sound of tiny hooves running across hardwood could be heard. Moments later the door flew open, revealing a violet unicorn filly.

“TWILIGHT!” The cyan filly cried out at her future marefriend. “You don’t know the day I’ve had. . . did you get shorter?” She asked, mentally questioning the lack of wings that she had gotten used to the unicorn having.

Twilight Sparkle blinked, looking up at the rainbow maned pegasus filly. “Who’re you?”

“Rainbow Dash. . . you know, element of loyalty. . . your mar- er. . . uh. .. your friend. . . you know?” Rainbow sighed. “You don’t remember me do you?” She frowned, thinking to herself. ‘Thought you wouldn’t, you wouldn’t even know me yet. . .’

“I’ve never met you before, why would I remember you?” The unicorn inquired, examining the pegasus filly up close, her muzzle only a few inches from Rainbow’s. “Nope never seen you before!” She concluded.

The filly pegasus blushed as her future marefriend’s muzzle hovered several inches from her own. “O-of course you have! I uh. . . Of course you know me!” Rainbow Dash said, jumping off of Sunflower’s back, pulling Twilight into a small hug and whispering in her ear. “Just go with it I’ll explain later.” She turend and smiled brightly at the adult mare. “See! Best friends, you can leave me here now!” She said, hoping it would convince Sunflower.

“I’m not really convinced. . .” Sunflower said shaking her head, “Are your parents home, little filly?”

“Who is it Twilight?” A pink alicorn asked, walking around a corner, her mane disheveled, several feathers in it and a pillowcase hanging off of one of her wings. She brushed herself off and smiled at the two pegasi. “Hello.”

“CADANCE!” Rainbow Dash shouted. “Am I glad to see you, you must remember me! Right?”

The pink teenaged mare tilted her head. “I can’t say I recall. . .”

“Uh. . . uh. . .” ‘Think Dash think! What’s something only Cadance would know?’ “Uh. . . Crystal heart!” Dash shouted.

Cadance thought to herself for a moment, giving an odd look at the cyan filly. “What’s my Cutie Mark got to do with this?” She asked, clearly puzzled by the outburst. “Are you related to King Sombra?”

“Of course not we defeated that monster.” Rainbow Dash said without thinking. “Er, uh. . . Kinda. . . I guess you could say in a way. . . I’ve been sent to stay here with my best friend Twilight. . . cause I’m learning weather magic at the magic school. . . Me and my best friend Twilight! Right best buddy friend of mine ever?” The pegasus said, still awkwardly smiling as she squeezed Twilight in another hug, trying to be convincing.

Twilight nodded eagerly, “Yeah! My best friend Rainbow Splash.”

Sunflower stood in the doorway, completely unconvinced by this entire display. “I’m still not convinced Rainbow Dash. . . I think you’re lying to me, these ponies clearly don’t know you, I can’t release you into their custody.”

“Well I don’t know this filly but, I can take her off your hooves. I’m really good with foals! Just ask Aunty Celestia.”

“I don’t know. . .” The pegasus mare said with a small frown. “I can’t just leave her in another pony’s custody. . . I’d get in trou-”

“No. . . really, I insist.” Cadance said in a rather regal tone.

“Oh. . . Uh just sign these release papers then, please.” Sunflower asked reaching into her saddle bag. She pulled out a small stack of papers, and gave them to Cadance to sign. “Sign there, there, and there.” The mare said pointing to three blank lines on the paper. “Oh and so you know, Princess, Rainbow Dash is not potty trained.”

Smiling politely, Cadance signed the release forms and nodded, acknowledging this new information. “Twilight, do you have ‘special underwear’ to share with Rainbow Dash? She might need more than a few.” She asked giggling.

Twilight blushed several shades of red. “I uh. . . N-no. . .” She replied, looking down at the floor. “We n-need more I only have enough for tonight and maybe tomorrow. . .” She whispered into Cadance’s ear. “A-as long as I don’t have an accident tonight. . .”

“That’s okay Twilight, we’ll buy more at the store tomorrow. I’ve got this covered, I always carry spare diapers in my bag!” Cadance said happily, she retrieved the purse from an end table and opened it, frowning when she noticed there was only two left. “Okay maybe I don’t have this covered. . .”

Still blushing, the lavender filly spoke up. “What if we have the guard get more. . . l-like that one time when we went camping up in Canterhorn Park?”

“You went camping as a filly?” Rainbow Dash asked, raising an eyebrow at Twilight.

“I go camping with Cadance all the time! B-but it’s usually in the back yard. . .”

“Well I’ll be going now then, I’ll tell one of the Guards to bring you a bag of diapers. S-Sorry for the trouble Princess Cadance.” Sunflower said bowing, before turning around to leave the house.

“It’s no trouble at all miss, oh and please get them to bring the kind that Twilight here wears too, the guards will know I mean.” The alicorn replied, giggling.

The pegasus mare nodded, leaving the Sparkle household. She trotted back to the guard’s office near her apartment to let her superiors know about Princess Cadance’s request for diapers.

As soon as Sunflower left Rainbow Dash let out a sigh of relief. “FINALLY, that mare was making it hard to do anything!”

“She seemed a little stuck up. Were you stuck with her long Rainbow Dash?” Cadance asked, ushering the fillies back into the house.

“Yes. . . She wouldn’t leave me go! She treated me like a foal!” The cyan filly said with a ‘hmph.’ Dash hopped up onto the sofa, bouncing on it a few times before coming to a rest. “So my reason for coming here is I need your help Twilight.”

“What do you need my help for? I’m just a regular old unicorn filly.” Twilight asked, joining Rainbow Dash on the couch, happy to have a pony around her age to talk to.

“What have I told you Twilight?” Cadance asked as she sat down next to Twilight, using her magic to clean the feathers up off of the floor and return them to the pillows they came from.

Smiling, the purple unicorn filly replied, “That I’m not just a regular old unicorn?” She asked.

“That’s right, you’re anything but.” The pink alicorn said, nuzzling the top of Twilight’s head.

“You sent me back in time. . . I think. . .”

“How could I have sent you back in time, if I had never met you until a few minutes ago?” Twilight asked, deciding to jump up and down on the sofa cushion.

“Like, fifteen years in the future you do some magical spell on me to make me relax and I get worked up while you start to do the spell and somehow that messed it up and sent me back in time. . . I think. . .” Dash explained. “I dunno I didn’t listen to your egghead explanation about it, You were trying to make me relaxed about my Wonderbolt training. . .”

“A wonderbolt who’s five and wearing a wet diaper?” The unicorn filly asked, giggling at Rainbow’s reaction.

“HEY! I never said my age!” The cyan filly protested. “Besides its your spell made me younger!”

“Are you wet?” Cadance immediately asked, her foalsitting nature kicking in.

“N-no!” Rainbow Dash said, frowning at Cadance. “I’m perfectly potty trained thank you very much!” She said, knowing in her current state she wasn’t. “Just send me back into the future about fifteen years and this’ll all be over.”

“I can’t just send you fifteen years into the future. Time Travel’s a really complex thing, and I don’t even know if it’s possible!” Twilight shouted exasperated.

“Aren’t you Celestia’s student though? You told me you read about that stuff in Celestia’s library!” The filly crossed her forelegs. “You told me yourself you went back in time to tell yourself something before! Something about Tuesday I think. . .”

“I’m not in Magic School yet, and I’m not Celestia’s student!” Twilight said, starting to get irritated. She wanted to continue her pillow fight with Cadance. “And even if we could send you to the future, how do we know you aren’t just trying to wreck it?”

“But that doesn’t even make sense! Why would sending me into the future help me destroy it?” Sighing Rainbow Dash frowned. “Are you going to help me or not?”

Sighing to herself, Cadance nodded. “We’ll help you, but you have to listen to Twilight and I. I’m nearly a grown mare after all, and Twilight’s a few years older than you.”

“By my perspective I’m older than both of you. . .” Dash retorted, rolling her eyes. “I’m nearly twenty one. . .”

“Says the filly in a diaper!” Twilight teased giggling, she jumped off the couch and galloped upstairs, returning a few moments later with a large book of fairy tales. “Foals love fairy tales, a-and so do I. Maybe it will give us an idea on how to get you back to your own time?” The filly asked climbing back up onto the sofa, seating herself between Cadance and Rainbow Dash.

“Twilight no more teasing, or we won’t bake cookies.” The Princess said sternly, opening the storybook Twilight had brought them.

“I don’t have time for story books!” The cyan filly said. “I want you to send me back to my time, just magically undo what you did in the future Twilight!” Dash said grumpily.

“I. Don't. Know. How!” Twilight shouted back at the other filly.

While the two foals were busy arguing, Cadance gently prodded the front of Rainbow’s diaper, she felt her hoof squish slightly into the exterior of the garment. “Somepony needs a diaper change~” The Princess exclaimed suddenly, picking up Rainbow Dash then laying her on the floor below the sofa.

“No I don’t!” Rainbow Dash protested, squirming around as Cadance starts the changing process. “I’m not wet! Not at all! My diaper isn’t warm and squishy! It’s your hoof!” The filly cried out, unknowingly admitting her diaper was soaked.

“Hush,” Was all Cadance said as she go to work, first removing the tabs from the diaper and folding down the front. “Twilight, sweetie can you bring me the wipes from my bag?”

“I can!” Twilight giggled, jumping off of the couch and bouncing over to the bag, getting the wipes out and grabbing a container of foal powder as well before making her way back to the pair of winged ponies. “Here ya go Cadance! Wipes and I even grabbed the powder too so she’ll smell good if she uses her diaper again!” The lavender pony teased with a few giggles.

“H-hey!” Dash frowned at Twilight. “That’s not funny!”

The Princess gently wiped Rainbow’s nethers with the foalwipes, even cooing to the filly while she was being changed. She sprinkled the foal powder onto the filly’s diaper area, and then slid a clean diaper beneath her, threading her tail through the hole. Then finally taping the diaper on snugly. “There! Foals always get cranky when their diaper’s wet.” Cadance said matter of factly, as she rolled up the foal’s wet diaper to be disposed of.

“I wasn’t wet!” Rainbow again protested. “You just thought it was because you could!” Her eyes started to water up a little bit as her foalish mind took over once again. “N-not fair!”

“Aww, don’t cry Rainbow Dash! I have to wear diapers every night.” Twilight said whispered, just barely loud enough for Dash to hear. She helped Rainbow back to her hooves and even offered a small hug. “Sorry I keep teasing you, I don’t really have any friends around my age. Do you know what future me was doing before you ended up here?”

Still sniffling Rainbow Dash nodded. “You w-were trying to make me relaxed. . . c-cause you said I was being all stressed out. . . s-something about making me younger. . . you used your crazy new alicorn magic. . .” The filly said through her soft sobs. “Y-you said you’ve been able to do this spell s-since you were little. . .”

“I can’t do that much magic though. . . I can levitate my books, carry Smarty Pants, and make things bigger or smaller.” The unicorn filly listed off the various feats of magic she could do in her young age. “I don’t know anything about regresseration magic!”

“Maybe it was making things bigger and smaller. . .” The cyan filly said, her tears starting to subside. “All I know is you said it was easy. . .” Dash explained, not realizing she was a bit off as casting the spell, and undoing the spell were two different things.

“Maybe if I try to make you bigger again it will send you forward in time?” Twilight asked, her horn becoming surrounded by a purple aura.

Rainbow Dash felt her body being engulfed in a tingly purple field, a few moments passed of Twilight straining and nothing happening to Dash before the cyan pegasus started to giggle. “I don’t think it’s working. Your head might explode if you keep straining like that. . .”

“I-It’ll work, I just need a few more seconds!” The purple filly responded, the field of magic around Rainbow began to shimmer then fade. Twilight released her magic, and nearly fell forward, having nearly exhausted her magic. “O-Okay so maybe that won’t work.”

“No more magic for the rest of the night, Twilight. You’ll hurt yourself if you’re not careful.” Cadance said, preventing the filly from trying anything else. “We can try to figure it out tomorrow morning, in the mean time. Let’s have some fun!”

“But Cadance!” Rainbow Dash groaned. “I want to go back to my time! And if I go back to the future everyone else will be happier because Twilight will be an alicorn, and you’ll be married to Shining, and I’ll be in the Wonderbolts!” The filly blurted out without thinking of the repercussions of telling the other ponies about their futures.

Cadance stared at the filly for a few moments, her mouth opening closing, trying to decide what to say. “What do you know about Shining Armour?” She finally asked, her expression no longer one of shock, but of interest.

“Well I’m pretty sure he cheated on you with the queen of the changelings while you were trapped in the caves under Canterlot. . .” Rainbow Dash said, a hoof on her chin as she thought. “Twilight once told me when she was younger she snuck in his room one night and started to examine his sta-”

Flushing crimson, the alicorn shoved her hoof into Dash’s mouth, effectively silencing the filly. “I’ve heard enough! There are foals in the room!” Cadance cried, worried Twilight would want Dash to finish what she was saying. “And you’re one of them!”

Blinking, the cyan filly tilted her head at the alicorn, uncertain as to what she said wrong, a moment passed of silence before the hoof left her mouth and Dash was able to speak again. “Am not!”

“Are too!” Twilight said huffing, it was only seven thirty but it was nearing her bedtime, and she hated to admit it but she was tired. “You are a foal! A foal wearing a diaper!”

“Nu-uh!” Rainbow retorted. “You are!” She said in a rather foalish tone, a yawn escaping her mouth.

“You’re both foals, Twilight, take Rainbow Dash with you to get ready for bed.” Cadance spoke firmly to the foals, pointing to the stairs with a hoof. “I’ll be up in a few minutes to tuck you in, and change Dash.”

“It’s only seven thirty, Cadance! That’s too early for a filly like me.” Twilight whined, stomping up the staircase to brush her teeth and put on her pyjama’s.

“Too early for me too! I’m up really late! Like till at least nine!” The younger foal said, her mind seeing something wrong with that answer but uncertain as to what it was. “I dun wanna go to bed yet!” She said as she was ushered up the stairs behind Twilight.

“If you’re not tired when I come up to check your diaper, then you and Twilight can come back downstairs and listen to the radio until you’re sleepy.” Cadance smiled, gently pushing Dash up the stairs by her rump. “Now go on, Twilight will lend you a pair of pyjama’s to wear for the night.”

Sighing Dash followed Twilight into the bathroom. “I don’t understand why you like her as a foalsitter, she makes you go to bed! That’s totally not cool. . .”

Twilight giggled and began brushing her teeth, when she finished, the filly helped Rainbow Dash brush her own. “She’s only making us go to bed because she wants to read her weird magazine. The one with the pictures of stallions on the cover!” She made an exaggerated ew noise before going back to helping Dash.

“That’s lame! She can cl- er uh. . . do that on her own time. . .” Dash said, blushing, starting to realize that this Twilight probably shouldn’t be hearing the things she’s been trying to say. “Hay I can brush my own teeth!” The cyan filly cried out as the lavender unicorn started to help her.

“Cadance asked me to help!” Twilight replied smugly, beginning to brush the other filly’s mane. “How can your mane be so tangly?! Don’t you ever brush it?”

“No! A mane like this is just naturally awesome! Ow! That hurts!”

“Stop pulling then, I’m almost done.” The lavender filly stated, drawing the brush through the prismatic mane again. She continued until Rainbow’s mane was silky, like her own. “There, now uhm. . .” Twilight blushed.

Rainbow tilted her head at the other filly. “What is it?” She said, moving one of her hooves through her mane to try and counter the work Twilight had done.

“I n-need to go to the bathroom!” Twilight shouted, crossing and uncrossing her hind legs. “Really bad!”

“Well go then, I’ll be in the hallway.” Dash said, turning to walk out of the bathroom, unknown to her that the diaper was actively starting to grow wet as she walked out, fully on display to Twilight.

The unicorn filly began to laugh quietly, when she noticed her friend’s diaper growing in size and changing colours. Once she had finished her own business, Twilight washed her hooves and trotted out of the bathroom. “You need Cadance.” Was all she could manage to say before laughing again.

“What? What’s funny?” Rainbow asked, not aware that her diaper was now soaked and sagging between her legs. “I don’t get it. . . your jokes have always been horrible, even in the future you know that?”

At that moment, Cadance came into view and noticed the prismatic maned filly’s sagging diaper. “Somepony needs a change~ Don’t they sweetie?”

“What?” The pegasus asked, turning her body so she faced Cadance, in her attempt to look down at her diaper she lost her balance and fell onto her haunches, the diaper squishing under her. At that moment Rainbow’s eyes started to water up, her entire sense of dignity seemingly washed into her diaper, ready to be thrown out.

“Don’t cry Rainbow Dash, it’s just a wet diaper. Nothing to be upset about.” Cadance soothed, picking the filly up and rubbing her back.

“I-it’s everything to be upset about!” Dash replied through sniffles. “I’m potty trained! I don’t wet myself like a foal!” She cried out. “What if I never get home? What if I’m stuck like this!?”

Twilight rolled her eyes, “Now you’re just overreacting. If I’m as smart as you say I am, then future me will figure something out!” She frowned, realizing she wasn’t helping the other filly calm down. “If it makes you feel better you can hold Smarty pants?”

Giving another sniffle Rainbow Dash looked at the plush toy that Twilight was offering. “L-looks better than how I remember it. . . B-big Macintosh should h-have tried to have stolen it now instead of the future. . .” She said, sniffling still. “Th-that thing still creeps me out in bed. . .” The filly said with a small blush.

Cadance blinked a few times, ‘In bed. . .?’ She glanced down at the violet filly, then shrugged. “Well lets change your diaper then Rainbow Dash.” Noticing the filly’s reluctance, the mare smiled. “If you really like being wet I can leave you in it.” She teased, giggling.

“Is it like a Sparkle family thing to try and see my private parts?” Dash sighed with a blush. “I still blame Shining for not knocking on the door. . .” With another blush the filly looked up at Cadance. “F-fine! B-but m-make it fast. . .”

“It’s not like I’ve never seen inside of a filly’s diaper.” The alicorn said, taking the filly by the hoof down the hallway to Twilight’s room. Once inside, Cadance spread a changing mat out on the floor and laid the filly down on it. “I know you think it’s weird that I’m changing your diaper, but unless you can change yourself, you’ll have to get used to it.” She teased, unfastening the tapes on Rainbow Dash’s diaper.

“Fine.” The rainbow maned filly huffed as she crossed her forelegs in protest. “But I won’t like it!” She said, blushing profusely as her wings suddenly pomfed out at Cadance wiping her clean.

“Aww, somepony likes her diaper being changed~” Cadance said softly, grabbing another wipe. She gently wiped from the top of Dash’s fillyhood to the bottom, before sprinkling on foal powder. “You’ll feel extra clean with this on you.” She explained, sliding a clean diaper underneath of the filly, and threading her tail through the hole.

“Do not! A-and I won’t feel clean until I don’t have to wear diapers.” Dash protested, her muzzle still as red as an apple.

The mare finished by taping the diaper snugly around the filly’s waist. “Well you smell clean, and you’re just adorable wearing that diaper. Come on, let’s go get you into some pyjamas.” Cadance replied warmly, holding her hoof out for the foal to hold.

Reluctantly Rainbow Dash took Cadance’s hoof, her eyelids starting to feel heavy as she let out a yawn. “N-not tired.”

Twilight giggled, hopping around her bedroom with one hoof through the leg holes of her pajamas. A purple pull up with light blue stars near the front covered her plot. “Cadance! I’m stuck.” She frowned.

Cadance chuckled, letting go of Rainbow’s hoof, she helped the other filly into her pajamas. “Your turn Rainbow Dash, do you prefer light blue with lightning bolt designs, or violet with flowers embroidered on them?| She asked holding up both pairs of pajamas.

In her tired state, the filly’s mind wasn’t comprehending the choice and her regressed decision making took over. “Violet!” She said, not realizing her ‘uncool’ decision until it was too late. “W-wait! I meant-”

The alicorn silenced the filly, and got her dressed into the pajamas. She briefly struggled with Rainbow’s wings but eventually got them secured to the filly’s sides. “Are your wings comfortable?”

Ruffling her wings the pegasus nodded. “Yeah. . . feels weird though. . .”

Twilight hopped into her large bed, then helped the pegasus filly up after her. “There’s lots of room, and my bed is extra soft! Oh and I’ve got lotsa plushies to keep us company.” The filly explained, snuggling into the covers.

‘Well I guess it won’t be the worst. . . at least I still get to sleep with Twi. . . even if we’re both foals. . .’ Dash thought to herself as she was pulled into the bed. Letting out a yawn and climbing under the covers she spoke. “It’s so cold in Canterlot. . .”

The unicorn filly wrapped her hooves around Dash, and pulled her close. “Not when we’re snuggling!” She said happily, treating Rainbow like she was an oversized plush doll.

The pegasus smiled, her plan of lying about it being cold worked. Suddenly the room got darker as Cadance began to dim the lights. Dash let out a small whimper, afraid of the dark.

Cadance’s horn briefly glowed turquoise in colour, igniting a small magic night light on the wall closest to the door. “Goodnight sleepy heads. I’ll be making you pancakes for breakfast, so I hope you two will be hungry when you wake up!” She said, closing the door behind her as she left.

“Goodnight Dash, you’re a nice pegasus, even if you’re the only one I know.” Twilight whispered happily, snuggling a little further into the filly.

“Night Twi. . .” Rainbow said with another yawn, her eyes already starting to close against her will as she began to fall asleep in the embrace of the purple unicorn.
