I'll be honest in saying that last week's episode didn't exactly rock me to my core as much as I hoped. I believe it has most to do with that central absence of Joshua Jackson, and much as I love Seth Gable, he doesn't quite fill that space in our hearts. Nor is he meant to. Across the seasons, Peter has always seemed like the odd one out. Walter and Olivia are clearly so much more interesting, lets just get rid of Peter. But now that he's gone, we really miss him. He had this charisma and endearment that just burrowed into the fabric of the show. How does it work without him. Begrudgingly and cynically, and this week's episode puts that pretty delicately.
Case of the week? Yeah, but with a twist we haven't really done before. The alternate universe has asked for Olivia's assistance in a serial killer case, escorting the serial killer's doppelganger from over here, a professor, over to glean information from the killer's home. There's immediately this sort of intrigue about Olivia and Altlivia working with one another, and a mutual frustration between the two. Admittedly, Altlivia is a lot more nonchalant about the ordeal, because what does she really have against the other Olivia? She's something of a competitor, and that's how she really sees it.
Olivia, in the meantime, has so many deep issues with Altlivia. It's not just the fact that the woman stole her life, but she realized that her life in the alternate universe, for the most part, has been so much better. She's happy, cheerful, and honestly possessing of a freedom that our Olivia doesn't have. Altlivia is what Olivia would have ended up as if her life had gone as she hoped it would. This may be stating what's been obvious all along, but it's so much more prevalent when the two of them are in a scene together.
