Gaslighting Your Parents Into Thinking You Have A Sibling by VoidWalker81
Fandoms: Batman - All Media Types
23 Dec 2025
Tags
Summary
I had just read "Hey Look! Free Sibling!" by @S_C_G and randomly thought of an alternate universe where they didn’t climb the fence to Wayne Manor and Tim hacked her a birth certificate and online schooling and gaslit his parents into thinking she was actually his sibling, but she stayed away from them cause when they saw her they’d end up getting super drunk and have screaming matches about indiscretions in Hong-Kong, and they eventually sent her to boarding school for people with special needs because she was mute. Like, she could speak, but she just didn't because whenever she tried talking to them they got mad. (they weren't abusive)
Starts when they walk past Wayne Manor, Chapter 3.Tim pointedly walks past Wayne Manor, refusing to even look. He wished they would see him, help him; wished he could talk to his personal hero, Jason Todd; but it was foolish to even hope. Right now, his sister was more important.

Summary
“Hey Cass,” Brenda starts, collapsing into the chair across from Cass. “Wanna come over to mine and bake together on Sunday? I have it off.” She’s smiling kindly, confident and assured.
Cass thinks about saying that she’s busy, that her current plan for Sunday is to sleep through nightmares all day and patrol all night.
Suddenly it doesn’t seem so enticing.
“Okay,” she says instead and takes a sip of her boba.

Summary
‘Ma?’
She can say it now, but it is not right. It sits sullen on her tongue and tastes similar to soot. She does not have that, she does not have a ‘Ma’, she has only the remnants of one. Within her eyes and nose and skin, that word lives, upturning her veins like soil and rust. Peeling away layers as if it is trying to tear itself out.Cass wishes for it, still, even if it is futile. She wishes for it even when the branches bang outside and she is too terrified to wish for anything at all.

Or, a small fic about Cass and what the word ‘Ma’ or ‘mother’ means to her. -

Summary
For the record, Tim had thought that punching the disappearing-people meta was a bad idea. And then he’d punched the neo-Nazi government agent in the face, so maybe he didn’t have any grounds to stand on. And then the personification of American patriotism, shady American spy branches, and said neo-Nazi organization that was probably part of the aforementioned came after them, and that was completely his fault.
Or: Tim and Cass get themselves involved, which has never not spelled out trouble.

Summary
Cass thinks back upon her actions on a recent mission, and regrets it all.
You could be reared by David Cain, and trained as Batgirl, and not recognize the intense self-loathing and the slipper slope fallacy when your own mind commands it.

Summary
Cassandra Cain's life was dictated by a handful of facts. First, that her father had placed a curse of obedience on her when she was just a baby. Second, that she was on the run from him and could never let herself be caught. Third, that she was a murderer. And fourth, that she would never kill again.
But when she stumbles upon her father in the wreckage that was Gotham after the earthquakes turned it into a lawless no man's Land, all but the first of these things ceased to matter. How could they matter when Jim Gordon's life was on the line? And while Batman seemed to think that he could save everyone, Cass knew better than to expect salvation for herself.
She just needed to keep her curse a secret for long enough to save the commissioner's life. Even if it meant giving her life to do so.
_____
An exploration of Cass's origin story set in a world where her silence is instead a symptom of a curse of obedience.
