I'm legitimately curious how Gotham will portray Jeremiah as the Joker in that, since the show put so much of Joker in Jerome, they'd need to do a lot to differentiate so it doesn't feel like a retread.
But yeah, seems like everyone called it that Jerome would be the one to create the Joker in Jerome. But yeah, you'd think that he would at least be wary of that random gift.
