Bringing Joker in for The Batman 2 might put a new twist on the Batman-Joker relationship, but it’s still a relationship we’ve seen before.
As I think about all the possibilities, a Jared Leto return seems least likely while a new Joker in The Batman 2 seems most likely, with a Joker sequel falling somewhere in the middle.
As previously stated, one of the problems with bringing Joker in to face Battinson is that it might be too soon.
It would also rob other villains a chance in the spotlight to help tell new Batman stories.
