Aren't the Morlocks different,though? Weren't they targeted because they were impure,lower-level mutants? Callisto,Caliban and Marrow are the only ones I can think of. Do they have a relationship with the X-Men? Does the public acknowledge them?

I haven't read anything involving them in eons,but there was a villain whose name escapes me,but he targeted Morlocks. I know Gambit killed a lot of them,too.

I seriously doubt they'll do Alex/Lorna. They'd have to recast the actor and the story would take a different tone. Right now,it's a lot like Heroes. If Alex was around,they'd be closer to a team,like X-Force or something along those lines.
