John: Tim - the tape was created before Walter disapeared. Walter existed up till 2015. What happens after the final scene is essentially what Walter describes in the video (which Peter would be going to watch)-----------------------Yeah, but that tape was made post Observer invasion in 2015. In the timeline Peter is now in, Walter would have never had a reason to create that tape (since the invasion had yet to/never took place). So there'd be no tape of Walter telling "explaining" such things to him - nor of Walter telling him about a letter he wouldn't understand. So the question is unanswered - presumably Walter existed in 2015 - I guess we all assume he disappeared at the moment the Observers WOULD have invaded - but I'm not sure why that is. The timeline Walter travelled to the future from no longer exists - because of what Walter did in a 2036 that no longer needs to exist. Paradox.
Yes Marie is correct - but as we've already seen, for this show you have to suspend reality. Is it really that much more of a stretch to accept that "young Peter drowned in the lake, yet adult Peter exists in the 2015 timeline/universe" but then be unable to jump to a finale in which "young Peter survived in the alternate universe, yet adult Peter still appeared in the 2015 timeline/universe with memories of a timeline that in fact never happened?" I guess that just sums up that Abrahms has created a show/finale in which any paradox is just that - a paradox - and we're supposed to accept it. It's an easy way out, but I'm zen with it.
There's a number of questions I look forward to reviewing in hindsight. Is the whole story line of "The First People" - which I believe had their roots with Walter - now completely irrelevant? Weren't some of the Fringe lab hall-of-fame creatures based on that earlier timeline too? Does Peter even know the meaning of the White Tulip? Why would Walter send a message that made no sense to Peter? And even though Olivia had the Cortextiphan in her system in 2036, going back to 2015 she would not have had it so thus, would she really be tuned into a future timeline that did not exist during the final scene in 2015? Again - unanswered questions and fan interpretation is a good thing in my opinion - I just think there were a bit too many unanswered questions for a fulfilling finale.
