AN: This was a prompt from tumblr! And as I said in the first chapter this is also an AU. Hope you enjoy! It has been slightly edited.
She watches her prey silently, appraising the way she moves through the burnt down building. The fire was of course her doing, baking the inhabitants nicely is she said so herself which of course she did. The bastards deserved to die, she had seen what happened, she knew, she knew. Oh, she's not a vigilante, nope, not in any shape or form. You have to believe in justice to be a vigilante, to take justice that was denied into your own hands. No she just likes to hear them scream, watch the flames crawl up the sky and smell the roasting flesh. Demented she know but she hasn't been in the right mind for a while. Something happened. But let's get back to her prey, her prey that was once was a policewoman but she quit... The watcher wonders why, Mikasa though gruff and harsh at times, was perfect cop material. Mikasa had a since of honor to rival any superhero, so why would she quit? Finally bored with waiting to be noticed the watcher drops down, a smile on her face. When they were younger they were in love or at least she thought they were in love... Now Mikasa glowers at her, lips moving, no sound reaching her ears. She recognizes her name though. It's been so long since she hears anything. She had to teach herself how to read lips.
"Sasha."
That was her name long ago, a life time ago before she was broken, before her hearing and her voice was stolen. A laugh bubbles up her throat, grating on damaged vocal cords, and she reaches out a hand placing it on Mikasa's face. Her voice is gargled as she tries to speak Mikasa's name. She wants the once cop to join her, they could branch out. Do more than arson and fire related deaths. Did it count as homicide if they died of smoke inhalation? Of course it did. It had to. She burned them up and watched as their lungs filled with black smoke. As their screams turned to coughs. There is something in Mikasa's eyes as she reaches up to touch Sasha's damaged throat. Sasha allows the touch, tries not flinch as strong fingers stroke the scars, fingers that could easily break her neck if they wanted to. Mikasa's lips move again, harsher more demanding and this time she does flinch back, her own hand coming up to cover her throat. Her smile drops off her face. She doesn't like the way Mikasa's lips move. Mikasa must have noticed her flinch because her lips thin out and she lifts her hands and signs. She recognizes some of them others she doesn't. So she shakes her head and tries to speak again. It hurts but there is no gain if there is no pain.
"Join."
She holds out a hand for Mikasa to take. Gesturing around at the burnt down houses before pointing to herself. Mikasa's eyes narrow before understanding flashes and she speaks again. Sasha bits down a sigh and rubs her ruined ears. Mikasa has the grace to look sheepish and signs, slowly to her. 'Did you do this?' She grins, nodding her head.
'You're too messy. You'll get caught.'
"Join!"
Mikasa looks away, not answering but not rejecting and Sasha feels hope. Maybe it wasn't just her that though they would be together forever. Maybe Mikasa still loves her even though she's damaged, even though she is unhinged.
