Well, with Steph, I don't think her mother really likes the idea of her being a vigilante. Not to mention that for a while there her mother was addicted to prescription painkillers (or something like that) and was kind of out of it. Steph and Cass have bonded over the fact that their fathers are criminal jerks. (That being said, I don't think Steph's father has ever been like "hey, kiddo, join me in my next heist!" while Cass becoming an assassin would mean she'd be working with her parents, probably.)
