Today was the day Scootaloo would return to school. That weekend with Sweetie Belle had gone by a little faster than the orange coated filly had thought, she couldn't remember waking up this morning. But Scootaloo didn't think much of it, as she walked to school. There, she saw all her friends, including Rumble (who she had a bit of a crush on, not that she’d ever admit it).

Seeing Sweetie Belle was being awfully silent for some odd reason, Scootaloo called out to her. "Hi, Sweetie Belle, I really enjoyed our weekend together. I hope we can do it again sometime." She spoke faintly, hoping none of the other ponies would question her or ask her what she was talking about. Thankfully, nopony seemed interested.

Scootaloo was about to ask her best friend if she'd like to spend the night with her again (though this time it would just be a normal sleepover) but just then the school bell rang and Sweetie and the other ponies started running to get to class on time. Scootaloo, on the other hoof, just stood there, frozen in place. Something seemed off, specifically in regard to who her friend was interacting with. Normally Sweetie never hung out with Rumble and Dinky, and she’d never once heard her friend mention anything about them. So why was she suddenly spending time with them? And where was Apple Bloom?

The filly couldn’t dwell on the matters for long, class was due to start soon and she didn’t want to be tardy. Scootaloo shook the thoughts from her head, and ran into the school house, hoping to beat the clock! When she got there and had plopped down into her seat, the filly breathed a sigh of relief. Normally, this gave her time to talk to Sweetie, or any of her other friends. But this time she wasn’t so lucky, as Miss. Cheerilee came trotting in and started class.

Scootaloo tried to pay attention to the lessons as Cheerilee droned on and on. But her mind was distracted by other things. She had to talk to Sweetie, now! She had so many ideas planned, ideas that had to come out one way or another.

Regardless of her teacher talking to the class about some random pony in history, Scootaloo decided to try to quietly talk to her friend, who was just one seat ahead of her. It usually worked pretty well. "Psst! Sweetie Belle...Sweetie! Hey, I wanted to talk about our weekend!" She whispered, but there was no reply. Sweetie just wasn't paying attention, she seemed to be completely fixated on the lesson, which Scootaloo found even more odd. As much as Sweetie loved school, history was not a subject she was fascinated by (except for when she was interested in the old style carts used for the Applewood Derby), so why was she now paying so much attention to and ignoring her friend?

Deciding that there was only one way to get Sweetie Belle’s attention, Scootaloo scribbled a note on a piece of paper, folded it into a paper airplane, and threw it with her hooves without bothering to aim. Unfortunately, as a result, the paper aircraft completely missed Sweetie. Scootaloo watched the plane fly around the room, hoping it would just strike the wall, crash, and go unnoticed. But that didn’t happen, and the filly froze as the plane she’d made hit Cheerilee square in the muzzle. Not good!

Scootaloo gulped and shrunk in her seat, she knew what was gonna happen next. The first time she’d done this, she got a warning. The second and last time prior to this, she’d sent to the principal's office (who unfortunately was Spoiled Rich from what Scootaloo could recall, though all Spoiled had been allowed to do was give Scootaloo detention for a whole week). As this was her third time doing something bad, Scootaloo figured that Miss. Cheerilee would probably resort to calling her parents in for an after school meeting and a lecture about making and flying paper planes. So much for her bright idea.

Cheerilee opened the paper plane and read the note. She was confused by the message written on it and who it was addressed to. Instead of going to Scootaloo, the mare paused in her lesson, approached Sweetie Belle’s desk, and inquired of her. "I don't understand this, Sweetie Belle. Exactly what does Scootaloo mean by ‘Diapered Playdate’?" Her tone of voice indicated a pony that was deeply concerned, too concerned for her own good. The words “diapered playdate” could only mean one thing. But maybe these fillies were just joking around? Maybe this was one of those secret messages they wrote to cover their tracks if it was intercepted, and keep their teacher in the dark? But then what could “diapered playdate” be code for, and who in their right mind would use a code that involved such suspicious writing?

Scootaloo sat still, completely frozen in her seat! Why oh why did she have to put her name on that paper note? She could have probably waited till after class was done, and asked her friend if she wanted to play again. But no, she just had write it all down in a letter! But then, what was there to fear? If Cheerilee was asking Sweetie Belle then she obviously hadn’t assumed Scootaloo was being sincere and thought the filly was covering for something. Sweetie won't tell anypony the truth, she had promised not to let a soul find out. So her secret was safe from prying eyes and ears.

Or so Scootaloo thought. For all of a sudden, without thinking, Sweetie innocently blurted out. "Oh, Scootaloo and I like to play dress-up and act like foals in diapers. She's just so cute in her diapers." Realizing her mistake too late, the filly clamped her hooves around her mouth! But the damage was done!

Suddenly, a big poofy diaper formed around Scootaloo’s rump, as well as a pacifier for her mouth, and some purple mittens to protect her hooves. "Wait, why does my butt feel soft all of a sudden?” She thought, before the filly looked back at herself and saw she was in a diaper! She also noticed the pink pacifier and purple mittens, and became aware of the fact that suddenly all eyes were focussed on her! "Uh, it's not what it looks like, I swear!" She protested, as her seat was suddenly turned into a crib.

Diamond Tiara giggled, breaking the silence. Her laugh sounded just like it did when she used to bully Scootaloo all the time. "Well, well, well. It looks like I was right. You really are a foal after all. I always thought it was really odd that your mother was buying diapers, but Daddy said it wasn’t polite to ask questions. But it looks like the school now has a baby to take care of, maybe Miss. Cheerilee could put you in the daycare center that’s outside." She teased, tickling Scootaloo, who started to giggle. But suddenly, without warning she started to mess her diaper, causing Diamond and all the other ponies to cover their noses and gag in disgust, as a chorus of “Ew!” rang out.

For a moment, all that could be heard was the laughter of ponies. Before it grew darker and darker, and the light of Luna's moon filled the room.

Scootaloo woke up with a sudden shock, panting heavily! It took her but a moment to realize what happened. "Another nightmare, thank Celestia. But why do I keep getting these nightmares?” She wondered to herself. “And why did Sweetie have to tell everypony in that dream? Does that mean I can’t really trust her even though she gave her word not to tell?"

Suddenly, an awful smell struck Scootaloo’s nostrils, and it seemed to be coming from her diaper. Looking down, the filly noticed that wasn't number one, it was something else. She had a different kind of accident, a messy one at that. "Di...Did I just mess myself?! No no no, I can't do that! Only foals do that!" Scootaloo thought to herself, but as the smell started to get uncomfortable, tears started to fill her eyelids, and soon she started to let them out. The filly didn't quite know what to do in this situation. Should she get out of the crib and get her mother for help? Or she should stay here until somepony came to check on her? The more she thought about it, the more uncomfortable she got, and the smell was starting to get to her.

Sweetie Belle started to wake up, as she felt something drip onto her. “Water? Please tell me it's not raining.” She said quietly, as she sat up in bed. She looked up at Scootaloo, noticing that she was the one crying. “So that's where the water came from!” Sweetie realized. “But why is Scootaloo crying, what reason would she have to cry?” Just then, a rather bad smell hit her nostrils, she realized Scootaloo had messed her diaper.

“Scootaloo are you OK?” Sweetie asked with concern. Although she knew why her friend was crying, she still had to make sure everything was ok.

Scootaloo froze, her friend was awake, and probably could smell her little accident! This just wasn't fair! Why did she have to do this on tonight of all nights?! Trying to hide how distressed she was, Scootaloo put on a smile and said as innocently as possible. “I’m fine, Sweetie. I just... had a bad dream! Yeah, that's it!”

Sweetie said nothing, this had to be extremely embarrassing and possibly weird to Scootaloo. As Sweetie observed this, she realized she to had to use the potty, pretty badly, and there was no sign of Dizzy Twister anywhere. Maybe if she were to “accidentally” mess her diaper, Scootaloo wouldn’t feel so embarrassed and ashamed? Besides, Sweetie had been using her diaper the entire time she'd been at Scootaloo’s place, even if it was just for wetting. How bad can it be to go number two in her diaper, just this once? With that thought in mind, the filly stopped holding it in and let it into her diaper. Once she’d filled it, she found it a little hard to move, not to mention it felt terrible and very uncomfortable. “EW, EW, EW!” She screamed at the top of her lungs, realizing it was a bad idea. But she saw Scootaloo stopped crying and was sincerely smiling a little, so that was a plus.

Dizzy Twister started to wake up. She had gone to bed a few hours ago, but had been woken up by Sweetie’s yelling, and she soon became aware of a very strong and awful smell. When she got to the crib, she had to wipe her eyes to make sure she wasn't seeing things. Her foals had both messed themselves and clearly needed a change. The smell was quite overwhelming for her. “I hope this Is just a nightmare,” She thought to herself. “I don't mind changing them. but next time I need to watch what they eat. Goodness, I’ve almost forgotten how much of a stinker Scootaloo used to be!”

Scootaloo started to tear up again and quickly apologized, even though she ended up slightly lisping behind the pacifier. “I’m so sowwy, Mommy. I didn't know this was gonna happen. I had a nightmare, and you see, I…. well I woke up all messy and icky.” She sobbed, picking up her stuffed Dash plushie and squeezing it tight for comfort.

“It's okay, Scootaloo,” Dizzy softly cooed. “You don't have to explain it to me. We all have nightmare. Just relax and stay calm, I’ll get you and Sweetie Belle cleaned up. We wouldn't want either of you to get a rash, now would we?” She asked, picked them both up from the bed, and placed them on a makeshift changing table she’d erected at some point.

Dizzy Twister unfolded the diaper on her daughter first, she then picked up a few wipes from the table and started wiping her daughter’s coat clean. Then she did the same to Sweetie Belle, taking care not to move too fast or too slow. She then threw the old diapers into the diaper pail once she had finished, and then she put brand new diapers on them while sprinkling in some foal powder. These diapers would hold a little more, but would still be a little hard for them to walk around in.

Dizzy carried them over to her bed, there was still a bit of time left to sleep, “Okay you two. I think you two should sleep with me for the rest of the night. I wouldn't want my wittle foals getting anymore nightmares, now would I?” She cooed, putting them on the bed and then covering them and herself up with the sheets.

Scootaloo snuggled with her mother, she didn't really want to let go. All these nightmares she'd been having hadn’t really helped her at all with feeling secure, if anything they were really uncool and unnerved more than she would admit.

As for Sweetie Belle, well she wanted to say that she didn't have a nightmare, and that she’d only done it because she didn't want Scootaloo to feel sad. But that probably wouldn't help the situation much, so she decided to keep her mouth shut and just go to sleep.

The three slept wonderfully that night, but while they slept, Scootaloo knew she’d have to talk to Sweetie Belle in the morning. She knew her friend had used that diaper just to make her smile, the big question was why? Why would anypony intentionally mess themselves like that, just to make somepony else smile?

Author's Note

Originally this chapter would have been longer, but I decided to have the messy scene be separate, it has been a good 3 weeks since I last updated, so I'll try to hurry on the next chapter, I'll try to get it done hopefully in a week or two, depends how busy I am.

Also nice to see that Gdocks finally works with Fimfiction now. before it wouldn't let the Italic thing work when transferring from Docks, glad that got a fix.
