Etta thinks about this for a minute and then tells him to get out of here. Not "Get outta here!" like he's kidding, but actually telling him to leave. He stares at her for a while, not sure if she means it or not. Then he gets to his feet and takes a few steps towards her, and tells her he's going to fight for the resistance now. "You don't have to lie anymore. I already let you go," she says, but he says that's why this time he hopes she believes him. He points out that his cheek tattoo may come in handy, since there aren't many resistance fighters an active tat ID. I'd imagine that his tat ID won't be active for long, but we'll allow it for now. Then he tells her that she was right, he did see something in Olivia's eyes: "There was a certainty that I've never seen before, and I don't know how to explain it other than to say I felt ... for the first time... that we were supposed to win."
Then, after a long pause (Etta doesn't say anything), Gael asks why she's letting him live. God, just go already! Etta says it was something she saw in her eyes as well: Pity. "For all of us," she says.
Back at Harvard, Walter frees the tape from the recorder, and notes that the heat from the laser may have damaged the PVC. Astrid, who was gleefully wielding the laser too, tells Walter that she told him they should have gone slower.
On the tape, Walter tells whoever's watching that if they're watching this, it he's probably dead and his plan to stop the Observers has failed. But he has documented his plan on videotapes: "You must recover each tape and follow the instructions on each of those tapes to retrieve all the parts of the plan," he says, and once they do this, what they need to do will be clear to them. "If successful, this plan will restore us and rid the world of the Observers," he says. There's some more bullshit about destiny and stuff, but the static and scratchiness finally overwhelms the tape and it becomes unwatchable. I fear the same thing happening to my VHS copy of Tougher Than Leather, which to my knowledge hasn't been released on DVD yet.
Peter ejects the tape, and tries the time-honored tradition of blowing on it to make it work. Meanwhile, Olivia's comms device beeps. She takes it out to watch video of Gael running away to his freedom, before the camera angle swings around to Etta's face. "I'm on my way back," she says. Double meanings! Olivia smiles and says OK.
Peter, having blown on the tape sufficiently, puts it back in, and... well, all we really get is more from Walter about how important it is that they retrieve the tapes. Yeah, hurry up and amber yourself already, we got it! "You are humanity's only hope. Now you must retrieve the first tape," he says. And then he ambers himself, and -- wait, where's the first tape? Where's the first tape?? You've screwed us again, Past Walter!
