At the end of the film, Queenie ends up joining the dark wizard Grindelwald.
Alison Sudol says it took her a while to reconcile who Queenie "was in the beginning with the choices that she makes and realize she isn’t a different person she’s just abandoned in a really untenable circumstance."
She doesn't feel Queenie's crazy. “I feel like in some ways she’s too there and that’s part of the problem. She’s tapping into all human beings at all times and that’s a lot for one person to hold and everybody closest to her is always going, ‘Don’t read my mind.’ So she has a huge power and yet is made to feel like she’s nothing and that’s bad. That could make anyone feel crazy. And women historically have this huge intuition and have been punished for that intuition forever. How many women have been in a mental institution because they’ve been called crazy when they’re just not allowed to be honest or be who they are?”
Says Queenie feels like she was abandoned by Jacob, Newt, and her sister Tina. "Jacob doesn’t come with her. It’s not so much about Jacob not coming with her to the dark side, it’s like, ‘Jacob, walk with me, we’re in this together.’ And she doesn’t have those two, so who does she have? Newt’s kind of betrayed her — he called her out, it was embarrassing. What does she have?"
She doesn't think Queenie has gone bad. “I still believe in her heart of hearts she’s going over to fight what she believes in. Grindelwald is saying, ‘we’re creating a different world’ and the world that she is in is broken. I don’t believe she’s turning evil. It’s more like she’s trying to find somebody who is giving her an option. He’s manipulating her but he’s manipulating everybody. He even did that with Dumbledore.”
