Fan Casting New partnership? in X-Men: First Class

Magneto receives a visit from Moira in prison. He questions whether Xavier sent her to see him, but she says Xavier has no idea she's there. She then says she thinks they could be allies if he behaves. And she asks if he's heard of the Hellfire Club. After she leaves, she gets into a car where Sebastian Shaw is waiting for her. He asks how it went, to which she replies that it's still a mystery. Then it's possible to see her shapeshifting and her skin turning blue.
