You reefrring to this? I dont see the schooling. All she did was explain to Storm how she knew Magneto was around after Storm doubted her claim. I didnt see it as a big deal. Magnetism is the ONE thing Lorna does and in 4 issues this was the first piece of dialogue that was specific to her as opposed to all the other generic scenes in the first 3 issues of her flying around.
Maybe Storm shouldnt have questioned the Mistress of Magnetism!
