Aside from the tech savvy part, we're getting a preflashpoint Cass characterisation as a big sister to Damian, which is what we should of got in the first place. Also yay for a piece of media that finally acknowledges that Cass is an big sister and is in fact older than Tim and Jason lol.
That burnside suit is a let down but if that's my biggest complaint i'm beyond happy and ecstatic.
