“What I think is interesting in the story of Credence is that he has been betrayed and mistreated by both worlds at this point. He has been mistreated by folks in the wizarding world, and No-Maj or Muggle folks as well. And so I think there’s a great skepticism of everyone he sees. I find in Credence this feeling that if he’s ever going to look someone in the eye, it’s going to be to analyze and question their intent and their integrity, because he’s just been given no basis to perceive trustworthiness or compassion in another person. And so I find that to be an important part of the exploration. I think he has very little knowledge of any of the Dumbledore folks at this point. I mean, there was a wizard alluded to, who Grindelwald was obviously portraying as a sinister figure to him, and I think that is the extent of his knowledge.”
