Fox is about to pull all of the toys out of the toybox. During the upfronts it was made known that for the second season of Gotham, we'd be introduced to The Joker and Mr. Freeze or at least the men who become them. Now we had a few Joker like plants through out the first season, so it will be interesting to see if one of those turns out to be the guy or if it's someone else entirely. As for Victor Freeze we may just get him as the scientist and not the villain at first.
Doesn't it seem like they've just about introduced all of the main villains in Batman's world? They should probably slow down and save some for a third and or fourth season.
