After seeing the film which Villains are you guys definitely not expecting to see.
I feel like Hush was teased and the idea that his father was maybe kinda killed by Bruce's works and gives Bruce a reason to factor into the next film more but an Orphan trying to kill Wayne because of his father was basically this film.
Two-Face also seems not as likely as we just had the DA die and it may seem repetitive. I wouldn't mind Harvey showing up as just a friend albeit with a dark side and we only get Two-Face teased but I'm probably alone in that.
I was back and forth on Court Of Owls but after seeing the film I definitely don't want them, I feel like Falcone being ultimately behind the corruption works well enough, and having Penguin fighting against other mob bosses for control of the city is compelling enough without a secret society.
