I really hope Scott and Jean reconcile and get back together, while doing their best to make sure that the events that Jean saw would never happen. It's possible, sure. The jean-Scott Summers family ( Jean/Scott, Cable, Rachel, Hope etc. ) is my favorite comic book family along with the Bat-family.
I don't think it's too hard to make these 2 reconcile and marry again once they're adults, while making them take care not to repeat the mistakes that they've seen happen in future. As for Logan-Jean, I think Logan-Storm would be better. Please don't make that mistake, Marvel !
Scott/Jean are just the perfect comic book couple, They're meant to be together and it is also NECESSARY for the space-time continuum.
P.S. Please cut Scott some slack. He's been through a lot of bad shit. Jean treating him that way was just wrong IMHO.
