*sigh* since Bass isn't on right now, I'll just explain it:
The final arc of New X-Men is "Here Comes Tomorrow". Basically in the future there are a bunch of different warring factions, including mutants, humans (who are nearly extinct) and ton of genetic offshoots. The bacterial colony, Sublime is creating mutant hybrid thingies and causing all sorts of chaos in an attempt to continue its goal of forcing all the different races to destroy each other so it can rule the earth once again. In the future, it has taken over the body of Beast (who's now huge, white and sort of symbolic of the Beast of the Apocolypse) and finds an egg containing Jean. She wakes up, but since, apparently, she wasn't supposed to "hatch" for a while, she doesn't remember anything and mindlessly helps the Beast destroy entire races. I recommend getting it, cuz I'm not going to explain the whole damn arc here.
