Relative Button

"Yeah, you got spirit kid, I'll give you that. More than your old man, anyway. In the joint, Chill told me about the night he killed your parents. He said your father begged for mercy. Begged. Like a dog."

- Carmine Falcone, Batman Begins

A long time ago, Bob brutally murdered Alice's family while she was away at school. Now, Alice has finally found him.

A brutal fight ensues, with all manner of items (we don't quite know how the toilet seat got into the fight). Alice ends up lying on the floor, with Bob seemingly triumphant.

Then he says the following:

"You remind me of your mother. Now there was a woman with some spirit in her."

Alice is incensed. With her last reserves of strength, she gets up and beats Bob. See also You Killed My Father.
