"This was the first time you saw the other side. You were frightened. Started a fire with your mind. It should have worked. This is the very sort of thing that William and I were preparing for!" says Walter. I certainly hope we get back to Olivia starting fires with her mind, because that would be bad-ass. Olivia angrily says that Walter abused her and the other children, but Walter says they were trying to help: "We were trying to make you more than you were!" Olivia's not buying it: "Is that what you were doing? Or were you searching for answers to questions that you shouldn't have been asking in the first place?" Walter protests that he was a different man back then, and Olivia -- growing angrier and more disgusted by the second -- spits out that she was a defenceless child.

That's when it dawns on Walter, why the process isn't working this time around: She's not a frightened child anymore, and is in fact a kick-ass FBI agent who isn't capable of the same kind of fear that the little girl was. Eureka ... ? Walter hadn't already thought of that? "If you want to save those people, you have to find your way back to that scared little girl," says Walter. Olivia asks how they do that, but Walter doesn't know.

So there's Olivia wandering through the dark hallways of the centre. She opens a door and finds the room from the video. Blackened except for the corner where she as a young firestarter was cowering. Olivia slides into a crouching position, which is where Peter finds her. He looks around asking if this is part of Walter's test. Olivia shakes her head. He asks if she's all right, and she shakes her head again. "No. I'm not afraid of anything anymore," she says. Look at it this way: you're the obvious choice to head up the FBI's Freddy Krueger division.

We're at Massive Dynamic now, with Nina on the phone with some underling, telling them to let her know if anything changes, and then she tells Broyles, "Four tremors in the last two hours. Most recent measured two-point-six," and Broyles tells an arriving Peter and Olivia that they're increasing in frequency. Olivia seems to feel personally responsible for not being able to personally see the glimmer around a building about to be sucked into an alternate universe, and Broyles points out that she didn't send the other building over here. Plus, it's not like it's a category on her performance review chart! Peter asks about "Plan B," and Broyles says they're compiling data: "Trying to predict where the next incident will take place. Satellite images, seismic activity, weather patterns." Peter offers a fresh set of eyes, so Nina escorts him to the lab while Broyles comforts Olivia by telling her that there's still time.
