And so now we know for sure in what world Peter is in and it wasn't all that difficult to figure out, but if you were still not sure, FOX ran the hashtag #WhereYouBelong in the lower right hand corner of the screen the entire episode.
The case of the week? Something about a dude killing people who are deeply in love. Not important except to set up that Olivia decides to allow the memories of the "other" Olivia to take her over.
The only other truly important things that happen in this episode are:
1. Walter finds something hidden inside Peter's eye that leads him to an apartment that has Observer gear.
2. Peter uses the gear to find a beacon.
3. The beacon activates back at Peter's place and our favorite Observer, September, reveals himself.
4. September explains that he's been locked away by the other Observers but that Peter has helped him get back. Peter then asks for September to help him get back home and is told he is already home (duh, been saying this for the whole season). September explains that he believes this is due to the fact that those who love Peter, and those Peter loves, could not let go of each other, and so the universe couldn't simply erase him from existence.
So now Peter knows that this Olivia is his one and only. And Olivia has made the decision to allow herself to be taken over by someone she thinks isn't her simply because she wants to be in love with Peter.
The final scene has Peter and Olivia in a loving embrace, finally as a couple again.
And it only took 15 episodes to get to the most obvious answer possible.
If I had to rate this episode, I'd give it:
80 out of 100
I am simply giving it a passing score for finally getting us to the answer that has been there all along. And maybe now, in the final seven episodes, we can stop dicking around and get to a kick ass show.
Sure, I will admit that I found that final moment to be very sweet, but it wasn't as intense as it could have been. And it wasn't as good as the moment they had in the car, in the gas station, just a couple of episodes ago. So, in the end, it was a pointless stalling tactic.
