Awesome! This...makes their relationship as characters much more complicated and (maybe just in my opinion) interesting. They have a surprising amount of similarities already anyways with what with both being children raised by League of Assassins and specifically created to be the best/lead the League in some way as the result of weird "breed with specific people" programs. I'm not sure if Damian finds the similarity comforting, extremely weird or both.

Also just realized that since Damian's only been with Batman and away from the League for a year or so, depending on when/how long ago Cassandra was with the League she might have been partially responsible for babysi-I mean training him for some period of time. Also wonder if she'd remember any of the brainwashed stuff.
