Supergirl, Season 4

J'onn:
That word, ahimsa, it's Hindu?

Manchester:
It means non-violence. Just something Fi used to say.

J'onn:
Tell me about her.

Manchester:
When I met Fi, I was... well, I guess you'd call it "ganged up".

J'onn:
Mm.

Manchester:
It was football hooligans. Sorry, soccer hooligans. Any excuse to break a window. We worked for me dad. He taught me how to win a fight. It's easy, once you know the trick. [points to his temple, indicating his brain] There's a switch in here. Keeps you from hurting another person. You can turn it on... [snaps his fingers] ...and off.

J'onn:
So, why did you stop?

Manchester:
I met Fi. She kept the books for the gang. Didn't hurt no one. No one but me, because one look from her, and I was dead, man, gone, hers. And she showed me... showed me other ways. Non-violent ways. Ahimsa. Then the boys found out she was an alien. Mm. Wasn't safe there anymore. So I told her... I told her to go to the States so she'd be safe.
