( not out of loyalty to wanda, even if he does love her. out of wanting to try and help bridge the weird multiversal gap between himself and tommy. it's better than using magnus as tommy does. billy isn't super anti-magneto right now. he's trying(ish) and billy can. acknowledge that a little. but he doesn't want to carry around his name either. )

I haven't had many, they're--not that complicated for me, honestly. I don't have anything to hide or any reason to try. Especially not here, where it's not like--my family's around. ( to get hurt. it hasn't happened (yet) but it doesn't mean it's not something billy thinks about. )

And I really don't remember it at all. I was a baby? Uh. Basically, Wanda wished for children with Vision, and obviously that wasn't going to happen naturally. So she used her power to create them, but magic can't create souls. Those were bits of Mephisto's own, which had been split into numerous parts. But Mephisto kind of wanted his soul back so he killed Wanda's babies for it.
