Why can't Wanda just meet a guy and have kids the normal way?
I mean that is an option, shes a very hot woman, she could have any guy she wanted, get pregnant and have kids. Yet she acts as if she must have the fake kids she made up, and go into another Universe and kill her other self and take over as their mother.
Bitch just go meet a guy, get pregnant eventually and you can be a real mother, no need to jump into other universes and kill someone to have it.
