After the big ruckus when Peter wakes up and Olivia says, “Welcome back” to him, I assumed she meant, welcome back to your own universe. I’m thinking that was Alter-Walter coming across the bridge to get him and he swept them both back to Earth2. Possible?
That wouldn’t make sense with his whole discussion with Walter afterward. I do think that Walternate was coming over and that’s who the bad guy was talking to at the end.
it looked like the same John Noble’s (actor who plays Walter) nose. Tried to see if the hands were the same but couldn’t get a good look at Walter’s (this universe) hands. Wonder where Peter went.
I definitely think that the guy at the end is Walternate. I hope they find Peter and tell him the whole story soon! I think he’d forgive Walter if he knew the reason! 
Unless Peter was never in the hospital and Olivia had been lying to Walter. And since they’ve not found him, she’s now telling him that Peter has checked out and has vanished.
What? Walter spoke to him AT the hospital.
But that was Alter-Walter (and Alter-Olivia) we saw in an Earth2 hospital where Peter was recovering (unbeknownst to him) from the rigors of his passage. At least that’s my speculation.
then what’s with the creepy Alter-Walter scene with Newton injecting him with some sort of fluid and holding hands?
Peter, left our Walter and our Olivia, Alter-Walter is in our universe trying to find Peter and take him back home to alternate universe. Or perhaps Alter-Walter wants to kill our Walter for taking his Peter…
I don’t subscribe to your speculation. Peter is in our universe still because there’s no need for that creepy hold hands scene.
Peter is in our universe because - he was asking/relating to Walter about the dead FBI agent and how he didn’t ‘explode’ - while I would be at a loss to explain how Walternate (or whomever, but the bet is good its Walternate) managed to cross over - but since that was his intention, and he had someone there ‘helping’ him with the journey, it doesnt bug me that he made it and Peter stayed.
It would make no sense for Peter to be in the other universe (assuming we’re only dealing with 2 as promised) since in the other universes, Walter would have no reason to fear/be upset by Peter’s revelations - he’d be more like “what are you talking about”.
I thought that Peter and Walter’s device managed to stop what Newton was doing on the bridge? How did the other guy make it through successfully?
I loved the end (although, I had really started to enjoy the Fringe team solving crimes with happy Peter making pies with his dad. Now, we’re back to bitter Peter!)
Wouldn’t Alter Walter be kind of pissed off at Walter Prime taking his son away all those years ago?
Not if WalterPrime had a chance to explain that he watched Alter-Walter miss the cure, and the only way to save Peter was to take him…
I would assume that is the thing that would have been driving him to try to come across all these years, yes.
In the hospital awakening scene I though that Olivia looked a little different while Peter awoke, maybe that was just supposed to be part of the strangeness of Peter waking up.
I also noted that the shades in the window were closed but there were buildings beyond the shades. So we couldn’t get a clue about which universe this was. I thought it to be interesting.
Probably means nothing.
I too think that the “ending” is not really in this universe…that we will find out in the next episode that Peter is on the other side now, and that is why he said, “You’re not my father” to the Walternate. Just a wild guess.
I doubt that, based on Walter’s reactions.
I’m positive Peter’s still in our universe. I read up a little about the next episode and Walter is worried about going back St. Claire’s (and deals with it by smoking pot). Anyway, since being with Peter is what allows him to be free then it’s only logical that Walter is worried about going back if Peter doesn’t want to be with him any more. If Peter were merely missing then Walter would just work on a way to find him and bring him back.
That wouldn’t make any sense in context.
But wouldn’t Walternate be just as upset that his “real” son no longer considered him to be his father? At some point, he must have figured out where his son went - maybe not the reason why, but still figured it out - and he would be eager to see Peter when he woke up.
And you can damn well bet if anyone would be the first on the scene, it would be OtherOlivia - dying to learn more about the other universe. Maybe the entire next season will be Peter trying to get back to his other universe home.
Peter couldn’t have woken up in the alternate universe because alternate Olivia wouldn’t have the first clue who he is or who he’s supposed to be. (Because he was taken out of that universe as a child, remember?)
Pissed enough to mount a longterm campaign to attack our universe, as witnessed by the manifesto they found in season 1 that had the same raised letter as Walter’s own typewriter. (Presumably Walternate’s typewriter has the same raised letter.)
