"The Babs here is interesting. Her explicit condoning of Kate is total crap - she's the least hardline of the sanctioned Bats about killing, which is why her and Hel work, but this is still way over her line and there's been nothing in her life recently that would begin to prompt that kind of drastic attitude shift."
Part of me is thinking that Oracle's leading Kate on, get Kate to trust her, so that when she does kill a crook, Oracle's on her ass like gangbusters.
