Nope, never mentioned. Welcome to having Bendis on the X-books where continuity is thrown out the window and he makes up things however he wants and ignores stuff that makes sense.
Man, this crossover just stunk. Every bit of reasoning for how things happened made little to no sense. "This proves humans hate mutants!" No, it doesn't work if you brotherhood idiots are the ones pushing the buttons and forcing it. SHIELD has a contingency for everything, how is this new? And yet again, no one of any substance or ramification died, and no one cares. Kitty: "You should have listened to me." Um, why? Every single person knows keeping the O5 in the present makes no sense and just stupid. You can throw characterization out the window to when Bendis is involved too. Nothing about this whole thing felt organic or flowed as if he was coming naturally and all had to be forced. The only thing I liked about this last issue was interaction between Jubilee and Shogo, because Wood's character work is one of the few things to enjoy about the X-Men these days.
I'm still not picking up Uncanny or All-New, and while people have said they started good, this crossover just proved to me I'm not missing anything. I'll stick with Wood's X-Men, WatX, and Amazing when it comes out, and X-Force and X-Factor as well.
