As it got closer to midnight, the wing grew stronger and weaker. The motion detector sped up and slowed down. There was no one pace either would go at.
As 11:00 came around, Fluttershy had disappeared without anyone noticing.

"Where did she go?!" Rarity shrieked. Twilight quickly had Rarity quiet down, just in case.
"Wherever she went, at least Applejack's over there." Rainbow Dash said, pointing to a figure ever so slightly illuminated by the frantic motion detector. Rainbow Dash carefully slipped Pinkie Pie off of her, who immediately grabbed her hooves. Rainbow Dash shook her off, clearly aware nopony else wanted her to walk over. Rainbow made sure to carefully approach the earth pony, but she began to notice scratches, scars, and a black liquid all over Applejack.

"Applejack? Are you-"
Before Rainbow could finish her sentence, AJ lunged at Dash. The pegasus jumped backward and saw her friend as a grotesque mess in the light. Black tentacles waved around in her mouth, thick black ink and blood leaking out of her eyes and wounds dripping onto the ground. Half of the front of her mane had been torn off and her neck had flesh completely exposed, covered in more ink and blood. Rainbow Dash screamed ran away from Applejack.

"Run!" she yelled at the others. Everyone immediately jumped off of the couch and follow Rainbow Dash. Applejack growled and ran after them, teeth bared.
"Guys! Over there!" Twilight exclaimed. Rainbow Dash spread her wings and launched herself backward slightly, allowing Twilight to take the lead. Twilight turned to the right and slammed a door open.

"Get inside now!" she shouted. Everyone immediately went into the hallway and as soon as everyone was in, she slammed the door shut. Applejack roared and bucked at the door, occasionally slamming herself onto it. Twilight blocked the door the best she could and ran after the others.

Rainbow Dash, who was at the front again, suddenly stopped, causing everyone else to crash and trip each other. As soon as Twilight made it over, Rainbow Dash grabbed her and shoved Twilight in front of her.

"I need to see who or what this is," Rainbow said, practically holding up the alicorn. Twilight lit up her horn and as soon as everyone saw who it was, Rainbow Dash dropped Twilight.

"F-FLUTTERSHY!!!" Rarity shrieked. She ran over and lit up her horn, looking over Fluttershy up and down. She went up to the rope on her neck and was about to untie the knot when the pegasus's ripped wings suddenly flared open and Fluttershy roared, lunging forward in the air. Rarity fell back and screamed. Fluttershy let out a blood-curling shriek and a few droplets of ink and blood flew out of her mouth, splattering the fashionista and everyone nearby with the two liquids.

Applejack immediately threw herself onto the door as hard as she could and broke it open. She lunged at the group and everyone jumped out of the way. Twilight blasted AJ backward with her magic and Rainbow Dash pushed Fluttershy out of the way, causing the hanging pegasus to let out an ear-piercing wail. The rest of the group ran after Rainbow Dash and Applejack quickly got up before taking off after them. As she hit Fluttershy to get through, she got her mane slightly tangled and pulled more of it off, but it caused the rope to snap. Fluttershy landed on her back and she hastily got up and ran after the others as well.

"Guys! Hurry! They're both after us now!" Twilight cried. Fluttershy lunged forward but her rope snagged onto something. It jerked her backward and she fell onto her back. She attempted to get up, but she failed to. She let out a howl of anger and Applejack immediately locked her target onto Twilight. When the four ponies split up, she followed Twilight. AJ lunged at the alicorn but she teleported to Rarity, the closest one to where she was.

"Do you think Rainbow Dash and Pinkie Pie will be alright?" Rarity asked.
"As long as they stick together. Hopefully, we'll meet somewhere."

"Pinkie? Do you think we lost her?" Rainbow Dash asked, slowing down her pace a bit.
"My Pinkie sense is telling me she's really close!" Pinkie Pie said, also slowing down to match Dash's pace.
"Can your sense tell where she is exactly?"
"Nope! But I know she's somewhere behind us."
"Then just keep run-"
A screech from behind cut Rainbow Dash off and the two ponies immediately sped up again. Rainbow looked over her shoulder and saw Applejack only about two yards away from them.

"Pinkie! Try to get on me or at least hold on really tightly to my tail!" Dash said, spreading her wings. Pinkie got behind Dash and quickly got on, making enough room for Rainbow Dash's wings. Rainbow looked at AJ one more time before taking off down the hallway. AJ let out a screech before speeding herself up. But even at full speed, she was unable to catch up to the speeding pegasus. Dash quickly looked for a way to hide and speedily got inside a nearby room.

"Rainbow? Pinkie?" someone whispered in the darkness.
"It's us, Twilight and Rarity. We're okay. Are you guys?"
"I-I think so." Rainbow Dash whispered back. Pinkie Pie slipped herself off of Dash's back and as soon as she got off, they heard hoofsteps outside. No pony dared to move or speak. They heard sniffing and hoofsteps running away.

"That was close," Twilight whispered as quietly as possible but still allowing the others to hear. Rainbow Dash quietly snuck over to the door and opened it. She carefully scanned the area to make sure the coast was clear. One she was sure it was, she snuck out of the room while the other three were distracted. She got out and quietly shut the door. She looked around for a clock. The closest one read 3:33 AM.

Aw man. An hour and 27 minutes left of this shit. Rainbow Dash thought. She heard Pinkie Pie shriek and cry, "WHERE'S RAINBOW DASH!?!?"
Rainbow was about to go back inside but she heard someone creeping down the corner. She spread her wings and flew up to the closest, thickest beam there was. Dash carefully hid in the shadows, making sure she couldn't be seen from below. She watched as Fluttershy came into view, the rope on her neck noticeably tighter. Rainbow Dash watched as the pegasus below prowled around, obviously catching the scent of all four ponies. She burst the door open and everypony inside screamed.

They all ran out of the room and Rainbow Dash covered her ears as Fluttershy let out a scream. She ran after the three ponies and Rainbow Dash immediately followed behind, dodging all the obstacles in her path. She kept an eye on the trio and the monster that used to be Fluttershy. When Fluttershy's weak spots were nearly all exposed, Rainbow Dash lunged at Fluttershy from above, delivering a strong blow to most of the exposed areas. Fluttershy howled and attempted to get up but found her front left hoof and back right hoof unable to move. Fluttershy growled and attempted to bite Dash, but failed to do so.

"Go while I distract her!" Rainbow Dash shouted to the others, holding Fluttershy's head down on its side with her hoof. Twilight Sparkle and Rarity continued to run but Pinkie Pie looked at Rainbow Dash. She knew the pegasus wouldn't be able to hold down that monster for long. She hesitated for a bit more before running after Twilight and Rarity.

Author's Note

So I decided to cut off the chapter and remove a small part at the end of the chapter. If you didn't read it before I removed it, here it is if you want to read it.

As soon as all three of them were out of sight, Rainbow Dash looked down at Fluttershy and smiled.

"You're not going anywhere, Flutters..." Rainbow coed before hissing and furiously biting down on Fluttershy's face and ripping off some skin and flesh. Fluttershy shrieked and used her right hoof to push the pegasus off of her, but Rainbow Dash pinned that hoof down and her smile grew as she looked at the struggling, dead pegasus below her hooves.

"You know, I've always wanted to know; once you're dead, can you die a second time?" Rainbow asked, her eyes glowing red and her canine teeth becoming fangs. She began to rip and beat the now helpless Fluttershy below her in the middle of the hallway. Fluttershy screamed and shrieked, even managing to holler a few words anyone could hardly make out. Rainbow stomped a hoof on Fluttershy's ribs, managing to break one bone on the cage and either shattering or cracking a few others. Rainbow Dash let out a maniacal laugh and said over Fluttershy's commotion,
"Who's the real monster now?"
