Back at the lab, the two mad scientists are trying to figure out what went wrong with the rat. Walter suggests a protein incompatibility. I was just about to say that! Boone says that's not it, that the contagion required cerebral spinal fluid as a catalyst, so the cure must need it too. "And the only spinal fluid we know for a fact is compatible is my own," he says.
Walter says that's out of the question, because it's too dangerous: "If you lose more spinal fluid, it could cause a brain hemorrhage." Boone insists that he was very careful to monitor how much fluid he's taken out, and another twenty-five milliletres would be safe. Astrid's against it, but Boone yells that they have no other choice. After a moment, Walter tells Astrid to prep the table.
Over at the club, Peter and Olivia are thankfully avoiding being hit on by more people, and Peter finally spots Valerie on his thermal imaging thing. "I got her. She's moving along the back wall." Peter's device looks kinda like a Virtual Boy, don't you think? Anyway, they lose her, so Olivia checks with Charlie outside, and he says she hasn't come out yet: "She's still in there with you, Liv."
Meanwhile, back at the lab, Walter withdraws some spinal fluid via a needle into Boone's back. It looks quite painful for him, and after Walter hands off the stuff to Astrid, he lifts Boone up and sets him down into his wheelchair. After blinking back tears, Boone notices the video camera sitting on a nearby table.
Back at the club, they've picked up Valerie again. Well, that was exciting. Olivia calls Charlie to let him know Valerie's heading out, and Charlie asks what she's wearing. "Black dress and freakishly blue eyes," says Olivia.
Valerie's walking hand in hand with some dude, and Charlie comes running up. "Valerie Boone! Are you Valerie Boone?" Valerie looks scared, doesn't answer. Charlie decides it's her, and shoots her in the shoulder with a couple of darts. Dude, it better be her, huh?
Back at the lab, Astrid relays the news that the agents picked up Valerie. Walter's working, his back to Boone, so it's Astrid who notices that Boone seems to be having a seizure. She alerts Walter, who orders her to get a TPA injection. While he tries to still Boone, Walter says, "You lied to me. You let me take too much spinal fluid." Boone chokes out, "How far would you go for someone you love?"
OK, let me understand something here. Valerie has been injected with something that makes her freakishly strong and provokes her into killing people and then ripping open their backs so she can drink their spinal fluid, and Peter and Olivia are just driving around with her in the back seat of Olivia's car? OH MY GOD ARE YOU SERIOUS? Well, sure, she took a couple of tranqs to the shoulder, so I'm sure she'll "be out for hours," as Olivia says. Peter asks where the siren is, and Olivia shows him. He flips it on and starts giggling as the lights flash and the siren wails. She asks him if that's why he wanted to drive. "Everybody should get to do this at least once before they die." Well, now that you'd done the former, the latter might be closer than you think, Peter: Valerie just opened her eyes in the back seat. Didn't see that coming.
So after the commercial break, Valerie lies there, eyes open, while Peter notes that Olivia looks a little downcast. That look says more than just, "I wish I hadn't let him drive." Olivia says she was just thinking about what Boone was doing for his wife. "Geez, that kind of love," she says, and then tells Peter that Greg asked Rachel for a divorce, and now is fighting her for custody. Peter says he never liked that guy, and Olivia laughs, pointing out he's never met Greg. "Yeah, but I met your sister. So I know she deserves better," he says. Like you, huh? Olivia says she thought Peter was a "card-carrying cynic," which he admits, adding, "But there's an argument to be made that beneath every cynic there is a frustrated romantic."
Well, that's about all Valerie can take with the blathering, so she attacks Olivia from behind, and Peter starts swerving all over the road. Olivia, fighting off Valerie, yells for Peter to get her tranquilizer gun, which he does, and he manages to shoot Valerie twice, knocking her out. Yeah, that kept her out for what, five minutes last time? Shoot her again! "I think she liked you," says Peter, and Olivia's too worn out to tell him to shut his piehole.
At the lab, Peter carries Valerie in and they get her strapped down. My god, I'd be terrified to do that. Olivia sees Boone and asks what happened, and Astrid tells her he had a stroke.
Walter injects Valerie with the antidote while Boone watches, and then he quietly says "thank you" to Olivia. "You're welcome," she whispers.
"Now we wait," says Walter, but they don't have to wait too long before Valerie starts writhing and straining against her restraints. She knocks it off and falls asleep before too long, and Walter checks her right eye. Still bright blue, at first, but then the eye clears to its more natural green shade. "Seems to be working," says Walter, only Boone doesn't seem to notice. That's cuz he's dead. Well, at least he died the way he lived: donating spinal fluid to his freak wife.
So as some EMTs are wheeling a still unconscious Valerie out, Walter gives Olivia a videocassette that he says Boone wanted Walter to give her. So the doctor who complained about Walter's twenty-year-old centrifuge had a camcorder that recorded to VHS? Do they still even make those anymore? "What is it, Walter?" she asks, but he just looks grim and walks away.
So Olivia finds a VCR. Maybe a Betamax, for all we know, and puts in the tape. Boone's on the video, saying, "Agent Dunham, if you're watching this, I suspect I didn't make it. But you and I had a bargain, and, uh, you held up your end." He promised her answers, and here they are: "In the time I worked with ZFT, I never dealt with anyone of significant rank within the movement. But I was able to gather some names, including some I suspect you've already heard of."
We don't hear any more, though, because all of a sudden Olivia's in a jazz club, where she finds Broyles, who seems to be alone. He asks if she's all right, and she tells him that Boone told them everything he knew about ZFT. "Did he mention David Robert Jones?" asks Broyles. He did not, said Olivia. "But he did mention another name that we've heard before." It wouldn't happen to be a name that we've heard this episode for the first time in a long time, would it? "According to Boone, the man who's funding ZFT is William Bell," says Olivia. Well, maybe he thought ZFT would fail and he needed a tax writeoff. Just don't jump to any conclusions, is all I'm saying.
