Fluttershy wasn't sure what the hay was going on when she heard the screaming.
Fluttershy was caught off guard when Twister told her that losing his wing was 'nothing'. He must have seen a lot of action. His eyes looked haunted, as if he never had a wink of sleep in his life, and his scars from the crash didn't help. He seemed friendly, but he also seemed disturbed. He looked like he was 25, maybe older, but after hearing his voice, in spite of its gruff edge, Fluttershy decided he couldn't be much older than her.
When Fluttershy and her friends left the room, Rainbow Dash immediately spoke. "I don't trust him." Fluttershy looked at her friend in surprise. "W-why?" Rainbow returned the look to Fluttershy. "It was obvious he's lying." Applejack nodded. "Ah could tell he knew somethin'...but Ah don't think we should judge 'im just yet. He seemed worried. Ah think he was lyin' for good reason."
Rainbow shook her head. "If he was worried, then that means he's guilty for something. He might be a criminal, for all we know!" It was Applejack's turn to shake her head. "Ah said worried, not guilt! It doesn't matter now. He'll tell somepony when he's ready. It's probably none of our business, anyways." The cowfilly continued her walk down the hall.
The hallway was white, paved, and the walls had dozens of doors leading into rooms in a sort of pattern. Nurses and doctors and guards kept moving around the hall, room to room and around corners. Needless to say, it was really crowded.
Suddenly, Fluttershy's blood turned to ice when she heard the sound of a mare screaming. Fluttershy turned her head, detecting the sound coming from the room they had just left.
The door to Twister's room swung open, and the assistant that was with the Doctor galloped away, screaming bloody murder. LITERALLY. Twister limped out of the room, blood on his hooves. He plopped his filthy safari hat onto his head as he left the room, limping down the left wing of the hall, opposite of Fluttershy.
The assistant ran past the group, crying in fear. Rainbow stopped her, and tried to calm her down to get an answer out of her. "What's going on?!?!" The assistant looked at the pegasus, her eyes wide with pure fear. "H-h-he killed him!" "Who killed who?" "Th-the patient! The one with the hat! he..." She started hyperventilating, her voice unintelligible at this point. Rainbow's eyes widened at this, and tossed Applejack a quick I told you so! look before flying towards Twister.
Why would he kill somepony? Fluttershy was suddenly frightened of the colt they just saved. Why would he kill a doctor? Why is he trying to escape? Something wasn't right here.
Rainbow was getting closer to the grey-maned pegasus. Twister wouldn't have any chance at outrunning Rainbow Dash, and Fluttershy expected her to tackle him before he got far.
What happened next was bewildering. Twister turned his head to see Rainbow, and somehow evaded her tackle. He moved like water; even in his weakened state, he was agile. Rainbow Dash crashed into a hospital cart as Twister continued his escape, a look crossing her face that said what just happened?. Several hospital guards poured out of the doors, trying to stop Twister's escape.
Twister looked undaunted as his limp changed to a run and then a gallop as the guards came towards him. He extended his one wing, as if he was preparing for flight. What's he doing?
Suddenly, when his muscles tensed to jump over the guards, Twister hit the floor and slid under the guard in front, leaped over the second, and jumped off the back of the third, his pace not slowing when he landed on his hooves.
Rainbow Dash shook her head as she recovered from the shock, and flew off around the bend Twister disappeared behind. Fluttershy and her friends tried to follow, but their pace was slowed due to the sudden chaos in the hallway. Guards were trying to move around the corner, while doctors and nurses, some with their patients, tried to escape down the path Fluttershy and her friends were originally going down.
When Fluttershy finally got around the corner, she saw Rainbow's tail disappear up the stairway. Why is Twister going upstairs?! She wondered as guards of all shapes and sizes pushed around her, trying to go up the stairway in a very unorganized fashion.
Fluttershy eventually got fed up with "Sorry, excuse me, pardon me.." as she tried to move around the guards, and simply flew into the air and up the stairway, over the heads of the guards. She had to abandon Twilight and Applejack, but Fluttershy needed to stop Rainbow Dash from chasing that dangerous colt. There's no telling what Twister might do to her!
The stairway spiraled upward, doors appearing on every other turn, leading to a new floor. Twister was running upward, ignoring each of the doors he passed. He seemed to be focused on reaching the roof...
Rainbow Dash shot upward, trying to intercept his escape. Twister stopped when Rainbow finally landed in front of him scowling. "Why'd you do it?" She shouted at Twister as his stone-grey eyes darted side to side, seeking a way around the sudden obstacle. Fluttershy stopped to hover a floor below, trying to keep away from Twister, but close enough to talk to Rainbow.
"R-Rainbow Dash! G-get away from him!!" Fluttershy's heart was pounding. She knew Twister was crippled, but if he can manage to kill a doctor in that state, who knows what he might be able to do to her friend?
Rainbow turned her head to look at Fluttershy, and Twister took his chance. He flashed his one wing, using it as a fake-out when he struck Rainbow's stomach with his right hoof. Rainbow fell, the breath knocked out of her, as Twister continued his escape.
Rainbow got up, her hooves shaking as she tried to catch her breath. Twister must be stronger than he looks, if he could knock down RD with a single hit. Fluttershy tried to help her friend up, but she shook herself away from her. "Why'd you distract me? I had him cornered!" Rainbow galloped away, trying to fly back up the stairway to stop the escaping murderer.
"K-keep away! H-he'll kill you!" Fluttershy was getting desperate. Of course, her headstrong friend didn't listen to her, and just kept flying towards him. Fluttershy didn't think her friend would survive, if Twister could knock her down with one strike. What could she do?
Fluttershy heard the guards downstairs, bickering about who's going up the stairway. THEY protect the sick and injured?! Fluttershy's heart felt like it was going to burst from the adrenaline. She looked back upstairs, seeing Twister's tail disappearing behind the top door. Rainbow Dash wasn't far behind her target.
Fluttershy flew towards the door, hoping that it wasn't too late to stop Rainbow. When she pushed the door open, Fluttershy found herself on the roof. It was a flat, open area. There were a few vents sticking out, of course, but other than that, it was as open as a plain. The sun had set, and the stars were coming out.
Twister was galloping towards the edge, as if he was going to jump off the building. Rainbow Dash intercepted him again, knocking him away from the edge. She scowled as she stepped into an offensive position, preparing to attack.
Twister shook the dust from his mane as he pulled himself up. He had a smirk on his face when he looked up to see Rainbow Dash. "You're not gonna give up, are you?" He spoke as if she was a kid bothering her parents for candy.
"Why'd you kill the doctor? He was helping you!" Rainbow's expression didn't change as she spoke. Twister laughed. "He was trying to kill me! You really don't know what's going on, do you?" He raised an eyebrow, a stupid grin crossing his face.
"This isn't a game! How do you know he was going to kill you?" Rainbow took a step forward, trying to intimidate an answer out of him.
"He tried to inject celestia-knows-what into me with a syringe." Twister sat down, as if he detected this would take awhile. Rainbow Dash's expression finally changed from a scowl to a look of utter bewilderment. "THAT'S WHAT DOCTORS DO!!!!! ARE YOU CRAZY?!?!" Fluttershy was now absolutely scared of Twister; if he felt threatened by a syringe, then...could he be mentally ill? Whatever he was, Fluttershy had only one thought crossing her mind: GET RAINBOW OUT OF THERE.
"G-get away from him!" Fluttershy could hear her own panic rising in her voice, but she didn't care. "H-he'll k-kill you, Rainbow! RUN!" Rainbow turned her head to Fluttershy. "I can handle him!" Suddenly, a flash of yellow and gray launched itself at Rainbow Dash, knocking her over. Twister had her pinned down, his hoof digging into her left wing.
"Check the syringe's contents. It's stuck in his throat." Twister twisted his hoof to injure Rainbow's wing, but not enough to break it. Fluttershy suspected if he wanted to, Twister would have done so.
Twister ran off, diving off the edge of the building. Fluttershy helped Rainbow up, and the pegasus galloped towards the edge. Fluttershy followed, and saw Twister had landed in the large garbage can pushed against the building's side. He jumped out of it, and started running towards the Everfree forest.
Rainbow tried to stretch her wings to follow, but let out a gasp and pulled her left wing back in. "He got me good..." Rainbow looked utterly enraged, but she was obviously trying to keep it bottled up.
Suddenly, the guards burst through the doors, finally having ended their idiotic bickering at the entrance. They spread out onto the roof area, searching for him. "Where did he go?" One of the guards questioned Fluttershy.
"Uh..." Fluttershy wasn't sure what to say. He seemed angry, and he might not like the answer. What if he doesn't believe it? What if...
"He jumped off the edge. He looked as if he was running towards the road leading to Canterlot. If you hurry, you can still catch him!" Fluttershy turned her head to look at Rainbow, failing to hide her surprise. Why did she lie to the guard?
"Gotcha! Come on, boys!" The guards rushed back down the stairway, trying to get to the entrance as fast as possible. Fluttershy saw Applejack and Twilight fight their way through the crowd, finally reaching their friends.
"What's going on? Where'd he go?" Twilight had an exasperated look on her face as she spoke. She had obviously been frustrated by the guards unorganized actions, and even more frustrated at missing the action.
"H-he got away.." Fluttershy was still trying to figure out what just happened. Rainbow took over explaining.
"He killed the doctor, but he said that the doctor was trying to kill him first. I tried to get more out of him, but he got my wing good. He ran off after that." Applejack's eyes widened at this. "Why'd he think that?" Rainbow stopped, thinking back. "He said to check the contents of the syringe the doctor was going to use on him. I think he's just crazy, but it might be worth the look." "Wait. a syringe? Why was the doctor using a syringe?" Twilight stepped in, an inquisitive look on her face.
"I don't know! Doctor stuff, I think." Twilight shook her head. "He wouldn't have needed a syringe if Twister had already went through surgery." Applejack turned her head to look at Twilight. "Waddya mean?"
Twilight sat down, thinking back. "The doctor wouldn't have needed a syringe if he was just making sure Twister was healthy. Syringes are meant to inject vaccines and other medicines to boost the immune system. Twister already went through surgery, so any immunity boosters would have already been injected into him before they left him to sleep."
"So, what, the doctor was trying to poison him?" Rainbow looked at Twilight with a raised eyebrow. "If Twister felt his life was in danger, then...maybe..."
"Wait. W-why'd you lie to the guards?" Fluttershy was still trying to understand why Rainbow did that, and she was lost.
"You saw them. They're idiots. Besides..." An evil look crossed Rainbow's face. "Revenge is more fun alone." Fluttershy couldn't believe what she was hearing. "A-are you suggesting..."
"That we follow Twister ourselves, and find out what he's up to?" Rainbow grinned. "Yes, that's EXACTLY what we're gonna do."
