So the ending has left a lot of questions for me ... like, is it possible that Bell has actually been orchestrating the entire thing from the season opener? If he was the one (either with or without Walter's full support) to stash this knowledge in the first place, how can we know for sure that it has not been done with the idea in mind that he/someone in his place would be able to retrieve that knowledge at a future time and reopen the portal at his discretion. IMO it's possible he has used Olivia to set things in motion with the intention that she WILL fail, and that the portal WILL be reopened from the other side ... since he is unable to do so himself.
Also I really liked Newton, probably because the actor has a striking resemblence to the fabulous Ralph Fiennes ... but really, why do they have to keep making the villains so badass? It makes me conflicted!
Peter crying at the end was killing me ... I am so so worried about what is going to happen when he finds out what Walter did now it's awful. Maybe almost losing his father will make him think twice? Or maybe it will make him even angrier .. This hiatus sucks.
I think it is for the best Walter lost those memories for good, though. He was worryingly satisfied to hear how badly the alt world was doing and I found it a little disturbing. I don't like him when he's sane.
+ Just clarifying, since I did not watch the episode live ... I take it there was no promo?
