She claimed them as her kids, the how of it all doesn't really matter their here their what she wanted, be a mother *shrugs* I get that it makes her uncomfortable to an extent her solo actually put that situation into perspective, that being said she claimed them so their partially her responsibility, her choice her fault. *shrugs*
I always found Wanda and those twins to be quite weird and Marvel kinda dropped the ball on it
It makes no sense to this day Tini Howard actually kinda put out the possibility current Tommy and Billy, aren't even real and just as fake as the original twins. Wanda's mama drama is such a headache that I tip my hat off to whatever writer eventually decides to sit down and make sense of it all.
You can't really take responsibility after kids are raised. They shouldn't have done it in the weird way it was. I guess this way it keeps her at her age, while they can be adults and neither are really affected by the other. But comics families are hardly ever satisfying. Because they either have to keep the kids in suspended growth like the Richards kids or have them be some weird thing like Cable or Rachel Summers.
Love is for souls, not bodies.
They knew Kid Cable longer. This is the same kid they raised for 12 years in the future. He is only a few years removed from when they were forced to leave him. Their interactions was sporadic over the years whereas they were with Nathan as a kid for 12 years straight. To me it makes sense that they would embrace Kid Cable bc he was taken from them and they are getting a second chance (or rather third)
