The thing that gets me about this is HOW?
The only things i can come up with is that
A) Either the weapon blowing up caused "local" time to become all screwed up (weak).
B) It happened BEFORE the events of the last episode, possible as none of the Xindi actally had ANY contact with earth and the Blue alien who helped them would have had any contact with them either and they werent able to get through to that orbital platform (but why would a WWII tech civ have an orbital platform?)
C) The guy helping them from the future has been tampering in things he shouldnt - rememeber him saying that his superiours would be really angry if they found out he told Archer what he would be doing 7 years from then.
D) The reptillians(hmmm)/guardians(more likely) went back in time in a last ditch effort to screw the timeline so that a key advance was never made and enterprise was protected by the spheres reconstructing space. (right out on a limb here
)
BUT THEN WHO THE HECK IS THE BLUE NAZI.... Argggg!!!!!
Your thoughts?
