If this is a never-before-aired episode, I agree, they should have said something somewhere letting us know instead of wondering. But that's why I like this show: it has the X-Files vibe that I enjoy so much.
If it is in fact, a third universe, is Peter's Mom/Walter's wife going to show up, too?
Or what if it's still the '1st' universe, did they bring Charlie over from the other 2nd universe? Again, will Ma show up?
Or are they going to pull over Oliva's partner/boyfriend (sorry, I can't think of the guy's name at the moment) from some universe, where he was a good guy, thus ending any hope for the near future of a Peter+Olivia hook-up?
