Polaris has gone to invite Magneto’s other children, Scarlet Witch and Quicksilver to his funeral. The twins tells Lorna that she cannot possibly expect them to go, let alone understand what they are going through being the children of one of the world’s greatest mass-murderers when Lorna reveals to them that she is their sister. The Scarlet Witch and Quicksilver do accompany Polaris to Genosha and Polaris declares that she is going to play “Devil’s advocate’.
