Fantastic Beasts And Where To Find Them: 10 Ways It Sets Up The Sequels
5. Grindelwald's Grudge
At the end of the movie, after fighting with 'Graves', Newt uses a revealing charm on him to show that - GASP - he's actually Johnny De... er, Gellert Grindelwald.
Yes, the greatest dark wizard of his age (and second greatest of all time) is brought down by a Magizoologist. And I can't see Grindelwald simply forgetting about that.
He already has reason to target Newt - the Obscurus - but there's going to be a personal grudge there too, once he breaks out of prison (something else we should see in the sequel). Then there's the matter of what Grindelwald says to Newt before he's taken away:
"Will we die, just a little?"
Yeah... no idea what the f**k he means by that. At a guess, because it talks loosely about partially dying and it's Grindelwald, I'd say it's about the Deathly Hallows, though I'm not sure how Newt fits into that. He delivers it directly to Newt, though, so there should be some connective meaning there. If Grindelwald is going to go after Newt in some capacity, then that makes sense as a way of keeping him around, even as the films become about something bigger.
