From Wellesley: Why doesn't Michael live with Max and Isabel on Roswell? Because when they all hatched, Max and Isabel were picked up by their nice family, while Michael went through the whole social-services/foster-care world and ended up with his pop.

From jules20: Anything more on Roswell? There's a cool episode coming up where Liz's diary is missing. She freaks and goes to Maria before she goes to Max, and, well, things heat up.
