thats a pretty great idea. I agree that they dont neccesary have to be family, just to adress the idea that they could be family seems pretty fine to me. To have a scene where Erik feels she could be related to his family seems like a really interesting scene for movie universe. He has been alone for his WHOLE life, so it would be a great scene. It would show the human side of Erik and how he needs someone close to him like all of us. we cant deny its a great concept and it would be a smart move by the creative team.
