As thewre are now reports on there that the actor playing Jerome will be doing a dual role in last shows for 4th season, and the runours are that either he will be becoming the Joker with a brand new personaility than Jerome, like a split one, or else he will be playing one of his family members, like an evil twin brother, who will assume being the Joker.

Either way, we will get to see the dsame actor as jerome and Joker!
