Finally an episode that moved the arc along. Took too long considering the writers felt they needed a full season to finish the story. Getting a little confusing/complicated with so many Olivia's/Walter's etc. For example when Peter told Lincoln 2 that Fauxlivia 2 was a good person... how would he know? Everyone in the new universe is different so why is he to assume Fauxlivia 2 hasn't changed in the new alternate one? Is it me or is Olivia 2 now more like our beloved Olivia than a couple of episodes ago? When Obsever told Olivia 2 that she was going to die are we supposed to care? I mean there's still three others and this one is the least likeable. For a moment I had forgotten he wasn't talking to our Olivia. If this one dying gets us back to the original gang... then get rid of her next episode.
