In my mind palace btw, there is a version of the world where after Dinah leaves the birds of prey, instead of scaling up the Birds of Prey Barbara instead scales down and starts reenacting early dinahbabs dynamics only with Helena. She obviously can't do the 'never knowing the true identity thing' but she'll start sending Helena on missions that involve Barbara picking out a fancy wardrobe,getting more intimate in terms of the comms etc. It's very clear to all non-Barbara parties that this is her taking Dinah leaving very poorly and also it keeps rubbing up against Helena's own issues about freedom and being controlled and like actually being wanted. Basically, I think it would be messy in interesting ways.

I do think cass would have no concept of traffic tickets. People would leave a ticket on her car for not paying the meter or whatever and she'd be like that idiot police man littered
