I still don't understand why they can't bring both Steph and Cass back. If they want Barbara to remain the only Batgirl, Steph could be Spoiler and cass could be Black Bat. I actually think it would be really cool if they did like a Team Batgirl/Batgirl Inc. with the three of them. They have an interesting dynamic and it would make fans happy. Goddamn it DC.
