I’m not a fan of making her more sympathetic either. While I don’t mind the change of origin, there really was no need for it other than reframe Mystiques character, it doesn’t change all that much for Kurt. It would be funny if Kurt was uncomfortable at Mystique attempts to be a mother, especially when she hasn’t really changed as a person. She still the devious, selfish person she’s always been. Kurt and Mystiques morals are always going to clash, which could make for a fun read.
Destiny doesn’t know yet either, I wonder if she’ll even care?
