I kind of think they are going to just do the whole triangle again and leave it up in the air who Scott ends up with (Jean or Emma). I kind of hate that though, I feel like all 3 of them need to breath for a bit and take a break from relationships to regroup. My ultimate wish for the fall is to see Scott leading a team, Jean leading a team, and Emma leading a team. They can do some relationship stuff when everyone is at home base, but in the field each one of them would lead their own groups and go on separate missions. Maybe that's not enough drama for the writers, but I like all 3 characters and I would love to see each one of them leading a book individually.
I think it would be kind of cool for Scott to lead X-Force with Cable and Rachel on his team, I would love that.
