I know Trial of Magneto had it's rough spots writing wise, I think there was a lot of editorial interference on Leah's original intentions. But my favorite part of all this is Lorna specifically acknowledging that Wanda is her sister, and Wanda and Magneto both just outright saying that even if he isn't her birth father (stupid retcon), that Wanda is still Magneto's adopted daughter and they are still 100% family no matter what. Hickman and other writers have been leading up to this for a while by having little bits here and there where it was obvious that Magneto and Wanda have been corresponding back and forth by e-mail for a while and he was trying to convince her to come to the Hellfire Gala.
