HOLY FUCK THEY SWITCHED OUT OLIVIAS. I kept going, "what. WHAT? They didn't just... did they??" because talk about gusty storytelling. What an interesting setup for S3. Also: this means we get to see more of Alterna!Charlie! With his arachnids! I hadn't realized how much I missed him on this show until Kirk Acevedo showed up last week.

Peter kind-of-sort-of-almost forgave Walter! And how wretched must it be for Peter to feel betrayed by both fathers. But he knows that one does love him.

Poor Olivia! I knew she was switched when Bell woke up. It seemed an obvious plot point. But I was afraid Our Olivia might be killed outright on the other side. I wonder how long it will be before Other Olivia trips up.

And Leonard Nimoy has left the building. That was the last acting he intends to do. Bye, Leonard. This new Spock is a poseur.

As soon as the grenades went off, I suspected they were going to pull that, but I wasn't certain because, um, that is kind of crazy to do. Except they DID, and it is AWESOME, because this means we get to see more of the other universe!

Evil Olivia is better at pretending to be regular Olivia than regular Olivia was at pretending to be evil, so this should be fun times. Olive should be able to beam herself out of that cell on her own, shouldn't she? Using her interdimensional transport powers?

Yeah, we had it nailed immediately, but that doesn't take away from the awesomeness. It also infers that Walternate had a backup plan arranged in case things go south. Because Evil!Walter is still brilliant.

I have a feeling that Peter will realize the truth pretty quickly, actually.

Maybe, maybe not. She doesn't have a whole lot of control over those powers, and it's unclear whether or not she needs to be at "soft" spot for them to work. Still, I do suspect she's on her own to get back.

He's leaving on a high -- he was awesome on 'Fringe," and got to be the one to hand over the mantle on the excellent new "Star Trek" franchise. You could have a lot worse exits. I wish him much joy painting and taking photographs in his retirement.

I thought that too (the switcheroo) - so does this mean that Olivia's power is innate and all the childhood torture was completely unnecessary? (You know, given that Alt!Olivia was able to open a "crack". Let's blame her for the crack in Doctor Who too.)

It's like the opposite of the Star Trek: TOS "Mirror, Mirror" episode. I would really like it if they already figured it out, or if Peter tweaks on it immediately next season. Unless Olive has been keeping an incredibly detailed journal, she won't last on a day-to-day level. I would really like it if they don't play the "manages to completely fol everyone" trope.

A good long stretch in that cell should do it. Some people build motorcycles in their mind, some might start focusing their powers. Then one day, Walternate opens the blinds, and there's no Olives in his drink.

I think the crack wasn't necessary at the weak spot, because Belly sacrificed his energy and beamed er energized er, transported er, powered their travel.

I think it should be Olivia's niece should be the one to immediately realize that is not her aunt.

all the childhood torture

And all the adult torture she's about to go through--I suspect there's going to be blast that takes out that wall early next season. 'Cause Walternate doesn't know what she's capable of when pushed.

Peter pretty much summed up the differences between them when he told Other Olivia what drives Our Olivia. And he saw her bafflement and said, "I guess she's nothing like you."

Actually, this ocurred to me. And the necklace thing is going to tweak all over the place.

Pacey had some good, understated reaction shots last night. This one, yes, and his reaction to Charlie. Well played.
