Dorian's creator ran off with enough synthetic souls that he could make a small army of Dorian style androids. Considering how powerful and efficient that one killer droid woman was.. the next season could focus on the people from the other side of the wall trying to take over the city.
I never got to see The Cape, but I remember the commercials for it. I never paid enough attention to the schedule and by the time I went to watch it it was already 7 episodes in.. I guess I should have watched it at that point anyway just to give it ratings. I think its on netflix now, I'll have to check.
I did like the very last scene of the season finale. It showed Dorian literally being almost human and it felt fitting to see the season end that way.
