Fantastic Beasts: The Crimes Of Grindelwald Trailer Breakdown - 19 Things You Must See
10. Credence's Obscurus Is Showing
Though you can't see his face in this sequence, that's Credence Barebone (Ezra Miller) firing off his Obscurus - that's the dark, parasitic force that grows within repressed wizards - once again, having apparently learned nothing from it seemingly destroying him the last time.
He's hanging out with the Maledictus (Claudia Kim), who apparently harbours a blood curse allowing her to transform into a beast, which she displays as part of a circus freakshow in Paris.
Elsewhere in the trailer, we get a better look at Credence, now tragically sans that hilarious bowl-cut, as he smashes up some hanging trinket, seemingly inside a circus tent. Can we assume from this and him being friends (or maybe more-than-friends) with the Maledictus that he's resurfarced in the circus as an attraction himself...somehow?
