An outline of the history-spanning, time-manipulating, inter-universal story of all five seasons of Fringe.
Down the rabbit hole we go.
2nd Edition: I've gotten some wonderful feedback and updated a few minor details on the timeline. Thanks to everyone who combed through this thing. It's better off for it.
3rd Edition: I made some design changes to emphasize certain plot points better, mainly those explaining the relationships between the timelines. The composition is also a bit more balanced. I'm going to start looking into selling prints soon.
Thanks a lot for this. It clears up some questions I had regarding the timeline changes. However, I am confused about one part. You say by preventing the Observer invasion, Walter's actions leading to 2167 is prevented and it's causing a paradox. Wouldn't that apply to everyone? Since Observer didn't invade, Etta was raised by her parents so she doesn't become a resistant fighter etc.
And if the Universe intends to not have any paradox, then shouldn't Peter be a paradox as well? A being that was meant to be dead is somehow there making it a paradox wouldn't it? Where's the balance that universe is supposed to preserve by introducing a new entity into the equation that was destroyed?
I think the intent of the writers was that the events that lead up to 2167 can be rewritten, but the actual events IN 2167 (which propagated the re-write) must remain constant. Etta isn't a resistance fighter, Walter never visits the shipping yard, etc. but it doesn't matter because the universe will "close the loop" by translocating Walter and Michael directly to 2167.
Regarding Red Peter, he is a paradox and his very existence lead to the creation of the Bridge and the erasure of Henry. This led to Etta's birth, and her martyrdom led to the Fringe team preventing the entire Observer War --- which ironically generates a history not too dissimilar from the pre-Season 1 timeline sans an Observer re-write.
@prindacerk: I agree with you that the "Walter-less" timeline segment is completely altered. Etta never becomes a resistance fighter because there is no Observer invasion to resist against. I didn't write that out because technically it's never shown or stated, but I think it can be assumed.
As for Peter's paradoxical nature; he's not supposed to exist, but Olivia manifests him back into existence using Cortexiphan, which gives her psychic universe-manipulating abilities.
@Ashok0: I specifically made the decision to make the simplest timeline(s) comprised only of details stated on the show. I think your theory is totally legitimate, but I didn't want to make any assumptions like that.
@anderssondavid1: But there's a lot of confusions involved as well. From your timeline breakdown, the machine was sent to the Cretaceuous period. But by whom? And why? In the original timeline, there was no need for it. We only see the machine get sent back in time by Walter and others in 2026 timeline. So the machine becomes a paradox as well (but doesn't get erased).
Also, how did the machine work without Peter? How did Walternate trigger it? It was never explained.
Finally, if the Observers wanted to restore the timeline back to the original, wouldn't they have simply reset the timeline by stopping September from interrupting Walternate? That would have restored everything as it should be. Instead they go through so much trouble causing battle between two universes that lead to destruction of many lives. Like September said, by saving Peter, he caused a ripple effect that ended with the death of the child of the Musician. And by distracting Walternate, he caused an even bigger ripple effect that was not fixed.
There was also the issue of the child. The observers were concerned about the birth of Henry who was not supposed to exist (they never explained why one child would have that much effect in the timeline). But because of the travelling between universes, Lincoln from Blue Universe ended up with Red Olivia. Was that meant to happen? It wouldn't have happened without Peter being there (which made Lincoln realize he had no chance with Blue Olivia). And the child born for them (Trevor) is also someone who wasn't supposed to exist (like Henry).
Yeah, I wish that they had explained the details of the Machine better. There's a lot that's unsaid, and I only wanted to incorporate facts that were stated on the show.
In Season 3 Walter keeps repeating that he's sure the Machine was built by William Bell, but Bell denies designing it.
My theory is that William Bell did design the machine in an alternate future. Why? I don't know. But he is a mad scientist, so maybe he didn't need a reason. He always does things because he can. I didn't include that on the timeline because it's never explicitly stated on the show.
Just like Walter will appear in 2167 from a defunct timeline, the Machine appears in the Cretaceous from a defunct future where it was built by Bell. Arguably the Machine still needs to be built on the new timeline to prevent a causal paradox, but we never see what happens so who knows how things play out.
As for how the machine worked without Peter: Walter says in Season 4 that the Machine activated itself and created the bridge for no reason at all. Walternate didn't turn it on. While never directly stated, I think the answer is just that Peter's psychic link to the machine transcends timelines. They are quantum entangled (however the show wants to define that).
I think the issue with Henry is just that he would cause further conflict between the universes. The war began over the kidnapping of a child. It's safe to say that putting this new child between the two universes won't change things.
Finally, I don't know why September never prevented his initial mistake. That's an issue with the show I think.
You state in the far most timeline (Amber TL for Blue universe) that the Cortexiphan trials didn't happen. But Olivia and Astrid talk about Olivia's Cortexiphan trial experience in Subject 9 (Amber TL). At some point Olivia ran away and the trials stopped a couple year later. I don't think the Cortixiphan trials happened in Red Universe, Amber TL. So Fauxlivia was not experimented on.
Hmm, I'd always assumed that the trials being referenced in that episode were from 1981.
But I decided to rewatch it, and they definitely say that the trials were from 25 years earlier, meaning they ended in 1986-ish.
So you're right! I wrongly assumed that Olivia never completed the trials because Walter never restarted them, but in fact it's because Peter didn't exist to keep her around.
I'll be uploading ed.3 tomorrow. I have a few more updates I need to add anyway. Thanks for the feedback and help!
Early in 404 (Subject 9) Olivia/Astrid go to MD to talk to Nina about the trials. I want to say she was in the trials until she was 9 then ran away. So she didn't "finish". If she was born in late 70s, then she ran away in late 80's and they continued a few years after (according to Walter/Bell). It sounds like she did cause the fire when she was 3-4 like the original blue TL (S1-S3)
Yes I think that's exactly right. Walter or Nina (I forget which at the moment) tell Olivia that she ran away, which I assume is a variation of the events of "Subject 13" when Olivia ran away and Peter convinced her to trust Walter and continue her life as usual.
And if the Universe intends to not have any paradox, then shouldn't Peter be a paradox as well? A being that was meant to be dead is somehow there making it a paradox wouldn't it? Where's the balance that universe is supposed to preserve by introducing a new entity into the equation that was destroyed?
