A Brother's Sorrow (adopted from @Eris345)

Chapter 23

Akumu groaned, his eyes flickering open (or rather William's) to see himself in a place he had vowed to never enter: the hospital. He tried to leap out of the bed, only to find that he had been strapped down in a manner that was most likely illegal. He tried to shout for help, but his mouth was conveniently gagged. Or inconvenient, depending on how you see it.
Dr. Franks stepped into the room, locking the door behind him. Bearing a malicious grin, he plopped his fat, pudgy body directly onto the man's legs, nearly breaking a bone in the process with his body weight. "Welcome back, Mr. Afton. It seems that now, you're under my care. I'll be sure to make it a living hell."
Akumu rolled his eyes, honestly not giving a damn about what the old doctor was saying. He had only met him in memories, yet he seemed too weak to actually kill him.
The doctor grabbed Akumu's leg, twisting it until it popped out of its socket. He proceeded to do the same with the other, looking up at the man's face to search for any muted screams of agony.
All he received was a blank, emotionless stare.
"H-how is this not working?!" Martin stammerer, backing away in horror until he fell off the bed. His fat rolls collided with the floor, creating a "plop" sound.
Akumu stretched his arms until he broke free of the leather that was restraining his arms. Sighing, he unbuckled his legs before popping them back into their sockets with a sickening "POP." Ripping the tape from his face, he lifted his puppet body off the bed before turning to the now-shocked doctor. "So, this was entertaining. I better get going." Tossing a wad of cash onto the floor carelessly, he threw himself out the window before walking off into the distance, dragging his now useless left leg behind him.
(Just a quick side note. Similar to when Ennard entered Michael's body in FNAF:SL, Akumu has no connection to the nerves in William's body so he doesn't feel pain, similar to his lack of emotions. It doesn't prevent him from being injured, however, so he has to take care of his new body, despite his...uncaring nature. This helps to prevent the eventual breakdown and decay of his host. Got it? Good. Also, Dr. Franks is an asshole. He'll come back, don't worry!)
