The Timeline Guy
Well, picked up UFF #13 today and while the story itself was a good starting point for this arc, it contained some things which turn the Ultimate timeline even more on its head. For one, the Ultimates are mentioned again (despite the fact that they haven't been formed yet). Also, General Ross (the same one who died in UXM #11) is still alive in this issue (surprise, surprise). So, this either firmly places UFF before UXM #11 or we can all just give up now of ever having a cohesive chronology of events in the Ultimate universe.
