Big yay on Batgirl Steph. I don't care what anyone else says, this is so IC for her and perfect. Keep writing her like this and I'll be psyched.
And Cass and Tim's running off (well, Cass and Dick never had a good relationship) seem very re: Bruce's death because it was always about him for them when it came to Batman.
I like the idea that Cass may go and become her own person as she's meant to be a major runner in this comic, up there with Steph and Babs. The idea of Babs' Bitches still makes me happy, even if it's not the Batgirl Corps.
