Thank you, thank you. But I will not be thanking you if killer dogs appear and try to rip my character's throat out. Then I will get stabby.
I would say, Huntress and Nightwing have worked/snarked together before. Maybe just a couple of times, but I would like to just assert that connection now. As for knowing each other's identities, I would say that either he knows hers or they don't know one another outside of the masks. If he knows hers, then he would have a leg up on her whole..."I run the mob" thing. And then draw some wrong conclusions about what she's doing.
GO AWAY WINTER! STOP MESSING UP MY PLANS! How has it been lately? It's been...uh...super nice here. Yay, Texas!
