But Laura hasn't really questioned hee existence in a while. She learned that she had a soul, she had friends who loved her, and she had blood relatives who love her.
She's a functional person who can have a life outside of the X-Men, something even Logan can't really claim.
If anything, I think this whole thing will make her question her loyalty to the X-Men, though I don't think it will happen right away. I think she's going to try and be happy and accept what's happening, but then something will happen that will make her realize how wrong everything is.
