Buffy and Angel in “Sanctuary”

She tried to kill you!

that was just...that was just a cry for help.

A cry for help, is when you say "help" in a loud voice.

I know Faith did some bad things to you

You can't possibly know

You can't possibly know what she's going through!

But of course you do. I'm sorry. I can't be in your club. I've never murdered anybody.
