Val is in the custody of Doom. In Fraction's run, the team was being destroyed by their powers. Like, their cells were breaking apart and stuff. Reed found about it first and of course didn't tell anyone. He took the family on a space trip to find a cure, but didn't tell them that was why they were doing it and said they were going on a vacation. Eventually everyone found out. Val was mad so she went to live with Doom.
they will always have a mystical bond that was started when Doom delivered Valeria when Sue started to experience the same difficulties she had with Franklin. But future Val seems to be the source of a lot that faith when she came back into the past to visit her younger self. Both Val and Franklin were given the cryptic message "All Hope Lies with Doom". After this visit, young Valeria visited Doom in Latveria without her parents' knowledge and began their secret alliance.
Val and Doom have a report that developed during Hickman's run.
On top of that even though she's three, she's almost as smart as Reed. Because of this she's allowed to make her own decisions and has.
Even though Sue and Reed might disagree.
The rest of the kids are with SHIELD at camp Hammond being looked after by Jim Hammond the original Human Torch.
