Who Says? (TMNT/FNAF Crossover FanFiciton)

Prologue

Raph holds his baby sister, Lilly, as Leo, Donnie, and Mikey performed in front of the children.  Lilly wasn't an animatronic like her brothers.  They don't want to stuff her into a turtle suit, since they loved her too much to do something that awful.  A young boy wearing a Leo shirt sees Lilly and sneers.

"Ew.  Why is that ugly baby on the stage?" The boy asks.  Raph's ears twitched in anger, but he tried to keep it together.

"I'd appreciate it, if ye'd not say that about me sister." Raph glares at the boy.

"You're related to that thing?" The boy makes a disgusted face.

"Look, laddie, I'm trying' t' be nice 'ere.  Stop makin' fun of Lilly." Raph sets Lilly on the floor of the stage.

"Oh, yeah? Make me!" The boy sticks his tongue at Lilly.  Raph lost it.  His eyes turned black with white pupils.  He snatches the boy's collar and pulls him up so they were eye level.

"I warned ye, landlubber." Raph's teeth sank down into the kid's head, biting off his frontal lobe.  Blood trickled down to the floor in a puddle.  Kids and adults scream and cry.  Leo takes Lilly backstage and Mikey and Donnie usher everyone out.  Raph's eyes cloud back to their original color and he gasps at the boy.  "What 'ave I done?" Raph sets the boy on the ground.

Mikey held Lilly close to his plastron while he tried to calm her down.  She wailed and hiccupped after seeing Raph bite someone.  Leo paced as Donnie tried to calm him down.

"What's gonna happen to Raph? To us? To Lilly? What if he's shut down? What if we're all shut down?!" Leo holds his head in his hands.

"Calm down, Leo." Donnie pats his back.

"How can I be calm about this?!" Leo frowns.  Raph walks in, wiping the blood from his mouth.  "Raph, why would you bite the kid?" Leo stomps over to him.

"The lad kept makin' fun of Lilly.  I lost it." Raph rubs his arm.

"She won't stop crying." Mikey hushes the baby and starts to hum to her.

"We can't let Lilly know about his or you.  You can just sit in Pirate's Cove and say you're out of order.  When she's older, we'll tell her." Leo decides.

"What? Leo, I can't live not even a second knowin' me sister won't know about me." Raph frowns.

"I'm sorry, Raph, but this is the way it has to be." Leo shakes his head.

"I wouldn't mind bein' out of order, but please don't have her grow up to think I don't exist." Raph begged.

"I'm sorry, Raph, but I've made up my mind." Leo knelt down and tried to help Mikey calm Lilly down.  Tears brimmed the corners of Raph's eyes as he glances at Lilly one last time.

"I'm sorry, lass, I was tryin' to protect ye, but now you 'ave t' live without me.  I'll see ye soon." Raph walks to Pirate's Cove and shuts the curtains, letting the darkness swallow him up in despair and guilt.
