the most simply is: Wanda is not the daughter of Magneto but Quicksilver yes, they are not twins, only brothers that take less than a year raised as twins, Pietro is the son of Magneto and scarlet witch mother of wanda, wanda is no longer a mutant, no problems, solved all. That t Pietro is the son of Magneto which it is something that all people who do not read comics think because movies, Pietro not have importance in the MCU, wanda is not mutat, all solved....
