Riddler has now completely and perfectly embraced his new role as a Gotham Supervillain. You have to make a show of it and make the police look like idiots .
Though now it looks like he's going to be joining the Court of Owls, which I guess isn't new territory for him since he basically already was working for them when he was helping Strange.
Ivy is basically now Penguin's perky henchgirl.
I see Freeze and Firefly still remember their little tiff at the season 2 finale.
So I guess Lee's moved on from just sniping at Jim to actually trying to convict him of murder. Heck, she'll probably find out about the Court of Owls at an inopportune time and just assume Jim is completely in on the conspiracy.
I guess I'm not surprised they directly lifted the Burton Catwoman origin, but like...what does giving Selina cat-powers accomplish at this point? Making her one of the "freaks?" She's still way too young to actually become Catwoman. There are other, more sensible, ways of developing her into her iconic identity then just going "revived by cats."
