Johnny Depp and Jude Law didn’t actually share any scenes together in the second movie, but Dumbledore saw Grindelwald’s reflection in the Mirror of Erised, showing his greatest desire.
It’s too late for J.K. Rowling to write Dumbledore’s sexuality into the Harry Potter books, but we are not even halfway through the Fantastic Beasts film series.
There are meant to be five films in total, leading up to the duel between Dumbledore and Grindelwald.
Their relationship is still at the heart of the series, and we know they’ll have to face off by the end of the franchise.
