It seems a lot of what happened before still happened, just for different reasons that don’t involve Peter.
The main universe titles were blue (or greenish-blue), not white. And I have a little trouble considering it “our” universe, even if it’s more similar than the redverse. I mean I hope the sort of stuff that happens there doesn’t happen here! 
I hope this ghost Peter business doesn’t go on too long, better get him recorporealized (or whatever) in another episode or two because otherwise it’s gonna feel like it’s really dragging on.
I don’t know, it seems like there’s a lot different. Like Lincoln never meeting Fringe before. Or when Olivia talked about losing a partner, she talked about John Scott. No mention of Charlie.
This is what I concluded halfway through…
To me the charm of Fringe (like Breaking Bad) is that when I think I know its going a certain way they career off in a different direction. They did it end of each season so far.
This isn’t the previous universes. Peter died (or didn’t exist, there seems some ambiguity about this from observers comments). Walter is plainly completely mad perhaps not brain operated. Belly could be lurking. All bets are kind of off until this point.
If Peter didn’t exist, then what caused the universes to cross? Comments seemed to infer that he did but both died. And still, then what caused the problems? Belly going across? Walter and Bellys small experiments?
It also seems as if there is another force in work here too.
Like I said, its span off again. Thats what I love about it.
That brings up another question. I couldn’t get a read on Fauxlivia, but Olivia didn’t recognize Lincoln at all. So either A) Alt-Lincoln (ParaLee?) never joined Fringe, or B) When Olivia got kidnapped over there, she stayed locked up and never met the Alt-Fringe team.
Loved Lincoln. Loved seeing Fauxlivia at the end. Hope they don’t drag out the ghost Peter too long.
I can’t remember where I read it, but trying to Google Fringe spoilers on one site somebody saw Joshua Jackson on the set for episode 4.
And seeing as how the one observer said that the timeline has been rewritten that is a strong indication that we’re still dealing with our universe and the alternate universe and no third universe.
I’m curious as to what reason the one observer will give for not erasing Peter.
Not a big deal, but when you post something from a spoiler site, you might want to use spoiler tags.
Good point, but I don’t know if I really spoiled anything. Maybe he’s still a phantom in episode four. Anyway, I’ll put something like that in a spoiler tag next time.
Refresh my memory: what happened to the central park wormhole leading to 250 million years ago? With the whole ‘first peoples’ stuff? Did they send the machine through? I somehow had in the back of my mind the possibility of maybe seeing something set in that time, but nothing in this episode seemed to hint at that…
Also, with Walter reviving the pigeon (which was ‘still quite dead’)… Did anybody else think ‘that’s gonna lead to a zombie episode eventually’? Because I think that would be awesome…
Oh, and on a screen when Lincoln entered the universes-connecting facility, I think it was the one where he had to identify via palm print, there briefly was an image of the ‘leaf’ code symbol… Have we ever seen code symbols in the episode, as opposed to as titles, before?
This show is the master at bringing things up and abandoning them. Remember when Peter was trying to protect some lady from mysterious bad guys from his past? Or when Broyles kissed what’s-her-face? Or…or… In a way, it’s a good thing that they feel free to focus on what’s interesting and exciting, rather than being tied down by plotlines from the past. But it also makes it clear that they have no idea where they’re going with the story, and are just making it up as they go along. JJ Abrams does not have a good track record with that sort of storytelling.
Uh… actually, no. 
Who was that and when?
…Also, did we ever see what happened to the guy Lincoln handcuffed in the opening, before his partner was attacked?
I’d say he did it ok with Alias, which had an ending and similar season end twists, but destroyed it with Lost…
Future Walter went back in time with the machine to set up the whole first people thing. But no one would really know that because Peter was the one that told them. But really, I considered the mystery solved. We’ll just never know how the whole thing went down unless they time travel again.
Ugh. The last season of Alias was awful. Nearly as bad as the end of X-Files.
It’s not like Abrams is running all these shows. He creates them and sets them up, nad then someone else takes over.
I never watched the end of the X-files, it got to end of season 2 and I knew they’d stretch out the explanation for as long as people will watch, so it got binned.
And while theres only so many times you can go and see a nice looking woman put on a wig, short dress and then break into another foreign secret headquarters below a nightclub in moscow, it got old by the end of Alias…
But at least what the bad guy was after was justifiable, however it ended.
Unlike, erm, protecting a bit of light in a cave in an island somewhere they’d crashed…
Of course, you’re right… definitely blueish/greenish. :smack: 
I was simply wondering if the orange coloration means a new alternate universe, or just a blending of the “blue” and “red” one.
It’s my understanding that Walt and Peter in 2026 used that wormhole to send the machine back. Not sure if we’ll ever see it in an episode (I certainly hope we do, I’m a huge sucker for time travel), but there ya go.
I noticed that too! Not sure what to glean from it though, other than a wink to the audience, perhaps?
He totally mouth kissed Nina Sharp last season. I can’t remember which episode, but I think it was early on. I don’t think they’ve addressed their relationship since.
Doing some Googling, he owes money to “Big Eddie”.
He also had an ex girlfriend dating Michael who’s abusing her, so he beats him up. Michael tells a guy name Gregory that Peter’s back in town. And that’s it. They drop the story line.
Nina. They still could do something about this. Broyles is divorced after all. Maybe they could reveal it’s because of an affair with Nina.
The only thing I can think of are those tunneling cylinders that have some connection to the other side and one of the Observers said he couldn’t touch himself.
Oh, he said, “dome”? I thought he said, “under that dung,” which made as much sense as anything else. I mean, I haven’t grown a whole lot of ears in my lifetime, but I would guess that under some dung would be a pretty good place to do it. I bet that no one would mess with the ear while it was growing!
