Summary
Oh yes she was free. Free from the lies that had forced her to keep going, leaving her blind to the destruction she left in her wake. She’d been right about addiction, just one lie was all it took for her to fall into its drunken depths; just one lie until one became two, three, four, forever. The truth was a dream and her world a blurry haze of her own creation, free of the pain, free of the memories…
Free of Tessa.
She’d been freed from her addiction but denied its momentary bliss, now cursed to wrestle with the damage she had caused herself, had caused everyone, including the only girl in the universe she had ever called a friend.
Tessa was gone, forever, now all that was left to do was scream.
OR:
Isolated and abused by those supposed to care for her, Tessa Elliot mourns the friends she never had and finds solace in the most unlikely cases - J the maid drone who sees her at her worst and still offers to take a share of her pain.
Decades later, J refuses to even say her name.

Summary
Cyn smiled back and for once it wasn't the monstrous face splitting grin from earlier but something that looked almost… genuine. It reminded him of the days so long ago when the sister he thought he knew was still with him, someone he could help and love and protect. Someone he would call family.
[Genuine smile. I knew you would come around Big Brother.]
"Well, you know me," N chirped, his smile widening to an almost painful degree. "I love... doing... anything!"
[I know you do, N. You will love being beautiful like me. Giggle.]
And then Cyn tore N's chest apart.
OR:
N gains wings, a tail and whole lotta trauma as he is slowly transformed from peaceful worker to rabid disassembler by an eldritch horror he once called his sister. A lot of oil, blood, vomit and gore so be warned.
