It was getting late. The moon was nearly full, but not quite. Fluttershy sat next to the window as she watched it with anticipation of the next day. She looked over to a small flask of grey potion that glowed slightly in the dark sitting on the windowsill.

"For an emergency, otherwise, I’ll need to go without any of this for the next six months..." mumbled Fluttershy to herself.

Fluttershy picked up the small vial, and took it to a locked cupboard in the kitchen. She had a rather unpleasant feeling, resulting from how much she was worrying. With only one dose of this left for the next six months, she would have to change...

After a few moments of waiting, Fluttershy decided to go to bed for the night, checking on Angel and the other animals before she lied down in her bed. It took a bit of effort to sleep and get her mind off of her worries, but eventually, with the calming sounds of the critters sleeping about, she grew tired and fell to sleep.

For most ponies, the next day was going rather smoothly. It had been about 8 days since an "incident" had occurred, as shown on the Town Hall's factory-like sign. Mayor Mare was a little anxious about that, expecting a disaster any day now.
Fluttershy had gotten up early, cleaned up, washed her mane, and had all of the animals taken care of by the time the sun rose. All of this done in a way similar to Twilight Sparkle’s usual OCD fashion.

"There you go Angel, that should last till tomorrow morning!" said Fluttershy as she trotted away, content with a mountain of rabbit food she had left in Angels food bowl.

Angel eyed the mountain of food confusedly, and with a yawn, decided to go back to sleep. He really did not know why or care why Fluttershy was up and about so early.
Fluttershy returned to a check list she had prepared on the coffee table, and pulled a pencil out of her frazzled hair.

"Twilight was right, this checklist stuff does help! Now all I need to do now is get the new bird nests from Rarity, and then make sure I’m alright for … it."

Fluttershy shook her head and readily grabbed her empty saddlebag. The critters came around her curiously, but she calmed them down and headed out.

Upon arrival at Rarity's boutique - and after a rather calm walk there - Fluttershy knocked on the door.

"Who is it?" Asked Rarity.

"It's me, Fluttershy."

Rarity opened the door revealing a rather messy look to her mane, "Fluttershy, what brings you here this morning?"

Fluttershy pushed her hoof along the ground "I was hoping you had those new bird nests done, if that is fine."

Rarity thought for a second, "Oh right! Come along darling."

Fluttershy followed her inside as Rarity went upstairs to retrieve the nests, and waited for her to come down from upstairs.

"Now I have most of them done..." started Rarity, before almost tripping down the stairs.

Fluttershy quickly flew up and helped rarity level the small stack of bird nests.
Rarity then continued "But those Eagles nests are hard work, I still need to get the right size twigs, but they should be done by tonight. You know I never understood why they think they have to have such huge nests."

"Oh, it’s not a problem." said Fluttershy while carefully putting the nests in her bag.

"I could bring them to you tonight..." started Rarity, but suddenly, Fluttershy interrupted her.

"NO!" she yelped, dropping a birds nest, "I-I-I mean, it can wait till tomorrow." she added, picking up and nest she’d just dropped.

Rarity stared at Fluttershy with a puzzled look. "Well, it wouldn’t be much, considering how much you help me with Opal."

Fluttershy quickly replied "No! I-It is actually very important that nopony comes by my house tonight!"

Rarity looked at Fluttershy, noticing that she was shaking and looking side to side in a suspicious way.

"Fluttershy, I think I know what’s going on." said Rarity with a poker face.

"Y-Y-You d-do?" asked Fluttershy, starting to sweat now.

"Yes, it seems pretty obvious to me." replied Rarity.

Fluttershy gulped "P-Please, I-It's not my fault!"

Rarity gazed at Fluttershy with yet another puzzled look, "Of course it is, and you’re too kind. You’re keeping a creature from the Everfree at your place tonight, aren't you?"

Fluttershy took a big sigh of relief, "Y-Yes! But please don't tell anypony, I don't want to, uh, startle somepony."

Rarity pretended to zip her lips shut, then winked. Fluttershy winked back in return, and finished packing the birds nests. With a quick goodbye, she headed out the door.

Fluttershy let out another sigh, then muttered to herself "Although this creature is very dangerous..."

After a long day of work, Applejack took her dog Winona out for a walk through town. As she went, she gathered a few groceries at the market. It was all going smoothly, yet Winona was extra energetic at the time being, sometimes getting in the way. As Applejack walked up to a vendor to get a few oranges, she did not notice Winona staring intensely at a nearby bird.

The bird noticed Winona, and sweated a little. In return, Winona growled, making the bird shake in fright. Then Winona charged, and the bird flew full speed in the opposite direction.

"Winona! Bad girl!" yelled Applejack as she dropped her bits and chased after her dog.

Winona ignored Applejack out of excitement, and chased the bird down the street. She managed to go under multiple ponies, trip the Mayor, bump through a congregation around some sort of show, and break a mirror. Applejack followed close behind, apologizing to everypony on the way.

"My word!" said some stuck up pony.

"What is your word?" asked Derpy as Applejack ran by.

Eventually, the bird flew across a road near Twilight's house, and Winona continued after it.

"Winona, WAIT!" Shouted Applejack.

Disregarding her owner, Winona continued running. She then suddenly was knocked to the side of the road from from being hit by a carriage moving at high speeds. Applejack quickly ran up to her wounded dog as she started to whimper.

"Come on girl, you know better than this!" said Applejack as she investigated Winona.

Twilight heard the noise, and quickly came out of her door, "What is going on out here?"

"Winona got hit by a carriage!" shouted Applejack.

She went back inside, and quickly came back out with a basket the size of Winona.

"Take her inside, and I’ll go get some help. I think Fluttershy can handle this." said Twilight

"I hope so." Replied Applejack as she lifted her wounded pup into the basket.

Fluttershy was finishing cleaning out her basement. The door to it was rather heavy so she hoped it would hold, although considering it was taken out of a prison, it should not have too much trouble.

Coming upstairs, she looked out the window as the sun started to set.

"Oh, no..." muttered Fluttershy fearfully.

Suddenly, she heard frantic knocking on her door. With a squeak, she quickly pushed an old bookshelf in front of the basement door.

"W-Who is it?" Asked Fluttershy in a startled tone.

"Twilight!" replied Twilight, who definitely sounded like Twilight. Fluttershy figured it was probably Twilight, considering Twilight sounds like Twilight, not too mention she has a book called Twilight.

Fluttershy approached the door. "I’m kind of … busy … right now, can this wait?"

Twilight quickly replied. "Winona got hit by a carriage, and I was hoping you could help."

Fluttershy looked out the window, and back to the door. She did not want to risk it, but under no circumstances could she leave an animal in pain. Thoughts raced through her head, but in the end, she decided to hurry and go help.

"I’ll be right there!" she said, grabbing her bag and a small animal first aid kit.

A few minutes later, Fluttershy and Twilight came into Ponyville’s library panting. Applejack looked over and came up to them, as Spike stayed by Winona.

"Fluttershy! Ah'm sorry I need you here, but Winona won't let me close enough to her wounds to deal with them right!" apologized Applejack.

Fluttershy looked across the room at Winona, and replied, "It's fine, this should not take long."

Applejack moved as Fluttershy quickly came up to Winona, "Oh you poor thing, your leg’s all smashed up! Just give me a few minutes here."

Fluttershy reached into her bag, and pulled out a neosporin-like spray, disinfecting the open wounds. She then readily got out a pair of sticks to use as a cast substitute. Then she readied some bandage and cut off the proper length to wrap around the leg. She then put on a doctor-like mask, and began applying bag-balm and bandages.

After multiple moments of operating, Fluttershy trotted back to Applejack. "Okay, I have her all patched up, just make sure she doesn't hurt herself until that leg heals, which will take some time. And give her lot's of water."

"Ah can't thank yah enough Fluttershy!" said Applejack as she trotted over to Winona.

Twilight turned to Fluttershy, "Good job Fluttershy, you really know how to take care of animals."

"Yea, your a miracle worker!" Added Spike.

"Yea, I can't leave any animal in pain." replied Fluttershy.

"Why don't you stay for some tea?" asked Twilight.

Fluttershy thought for a second, and with a look out the window at the sunset, she replied with "Oh no!"

"What is it?" Asked Twilight.

"I-I just have to go, now!" Said Fluttershy, as she started heading for the door.

"But can't you stay for..." started Applejack

"No! I just have to go now!" interrupted Fluttershy, right before having a sudden pain in her head.

"Why? Did you forget something?" asked Twilight.

"No, yes, I mean..." Started Fluttershy, but she just felt her head, and ran out the door without another word.

Applejack trotted up to Twilight, "Something is up with her..."

Twilight responded "Yeah, maybe we should make sure she is alright."

Applejack looked around, and said "Oh, she even forgot her saddlebag!"

Twilight trotted over and picked up the bag, "We should take this back, it is the least we could do. Spike, watch the fort for me!"

Fluttershy bursted into her door and quickly shut and locked it behind her. Outside, the sun was mostly set, and inside her critters were all cautiously heading towards their own beds. Angel hopped up and eyed Fluttershy as she frantically looked around, starting to sweat and shiver.

Fluttershy stopped herself, and took a few deep breaths trying to calm down, "It's fine, it's fine, I just need to lock myself up! Yeah, that's what I was going to do … Ow!"

Fluttershy rubbed her head, her headache rapidly getting worse as she started to shiver more.

"Oh no, oh no! Angel! Make s-sure all the other critters stay out of the basement!" said Fluttershy as she began moving the bookshelf out from covering her basement door.

Suddenly, knocking came at the door, along with Twilight's voice "Fluttershy! You left you saddlebag at my house! Fluttershy!"

Thinking quickly, Fluttershy flew over and shut the curtains, "J-J-J.... Uh, J-Just leave it o-on a b-bush or something!"

Applejack replied through the door "Are yah alright? You sound kind of sick."

"I-I’m fine!" replied Fluttershy as she pressed against the door, and she began shaking more, "J-Just l-leave now, p-p-please!"

Twilight replied "Are you sure you’re alright? We can help!"

Fluttershy started to reply, but looked at a nearby mirror, and gave an "Eeep!", as her eyes were starting to change color, and her hair was beginning to grow out.

"Fluttershy!? Let us in! we can help!" said Twilight.

"No, No, NO! L-l-l-leave! Gah!" Replied Fluttershy, with the headache getting even worse now, and her muscles tensed up as she shivered more.

"Alright! Something is up, ah'm coming in!" said Applejack through the door.

Fluttershy ran back to the other side of the room "No! Y-You can't help! J-J-Just leave! Before..."

Suddenly Applejack kicked the door open, and turned to see Fluttershy shaking at the other side of the room.

"What's wrong?" asked Applejack as she ran up.

Fluttershy quickly covered her face with her wing, "N-nothing, uh, S-s-somthing! But you can't do anything! I-I-I'm... Arg!"

Twilight rushed up beside Applejack and felt the side of Fluttershy's head, "Fluttershy! your temperature is through the roof! You need to go to a docter now!"

Fluttershy replied "T-That won't help it! Arg! Move this bookshelf!"

Twilight and Applejack exchanged puzzled looks, then Fluttershy allowed a bit of her eye to show "Just do it!"

Thinking quickly, Applejack pushed the bookshelf to the side, knocking it over, and revealing a prison like door.

"What is this for?" asked Twilight staring at the door in surprise.

Without answering, Fluttershy took the key out of the door, went in, and slammed the door shut, locking it.

"Fluttershy! What in tarnation are yah doing?!" yelled Applejack.

Fluttershy backed away from the door slowly, and moaned a lot, "P-P-Please, you can't do anything, t-there isn't much time left, j-just leave! I d-don;t want you t-t-to see..."

Twilight tried to open the door without success, "You just need a doctor!"

"No! I-I-I, I'm, I-I'm... ARG!" said Fluttershy before groaning more.

"What are you trying to say?" asked Applejack trying too look into the dark room.
Rather than an answer, Twilight and Applejack received a blood curdling scream from the dark room.

"Fluttershy! What is wrong?! I can't see a thing!" Said Twilight, as she quickly used a spell to illuminate the dark room.

Once the room was light, Twilight and Applejack shared a unison "WHAT THE BUCK!?"

Fluttershy was lying on the floor, with her hair grown all out, and visible canines growing. When she looked back at them, her eyes were yellow, and she said "J-J-Just, G-Go! B-Before... Arg!" before letting out another scream. Fluttershy grabbed her head in apparent pain, as her body changed more.

Twilight and Applejack watched in horror as their timid friend slowly turned into a frightening monster. Her hair grew out and darkened to a dark grey, while her mane and tail turned a dark red. Her wings grew out longer, and the ends of the feathers grew out, turning the same color as her new mane. The ends of her hooves then split up, and turned into large paws.

After a few moments, their friend resembled a large frightening pony-wolf mix.
Twilight sat there in shock, and took a deep breath, before asking "F-Fluttershy, are you alright?"

The monster looked up slowly. For a second, it gave an innocent gaze, but it quickly became an angry stare as the beast lunged at the door with a loud roar.

Twilight and Applejack flew back from the door in shock. Luckily, Fluttershy was being held back by the strong bars.

"Fluttershy?! What happened to you?!" asked Applejack in a scared tone.

All Applejack received was a loud howl, startling all the critters in the cottage. Angel quickly hid behind Twilight while shivering in fear, and the rest of the critters ducked into any hidden place they could.

Twilight, meanwhile, seemed to have a much better idea of what was going on than Applejack, as she stared at Fluttershy with awe.

"No, that’s impossible!" Twilight then looked out the window, seeing the full moon. "That was just a myth!"
