So elsewhere, Peter is hanging out in his car, watching as Tess walks down the street with some dude who I presume is this Michael character with the bruisy fingers. They walk up to the steps in a brownstone as Peter's cellphone rings. It's Astrid asking where he is. Peter totally lies and says he's putting gas in the car. "I think you should just -- come back," she says, and apparently no further explanation than that is necessary, because she doesn't say anything more and Peter doesn't ask any questions; he just hangs up and drives off.
Meanwhile, Walter's hooking Olivia up to all manner of electrodes and sticking that prong thing in her neck again. She groans in pain. "How long is this going to take?" she says, already forgetting that he didn't want to do it, but she did. He reminds her of that, and says what he's doing is pushing the boundaries of all that is real and possible: "We're not roasting a turkey." If he'd ever tried my mom's turkey, he wouldn't be so cavalier about it!
Astrid comes in, saying the library wasn't open so she had to go to the bookstore. Olivia asks what for, and Walter tells her that when she's in the tank, she has to listen to his voice at all times. "This is a technique I developed decades ago in this very lab," he says, brightly, before adding, in a lower voice to Astrid, "Most of which I don't remember." This would be around about the time that I'd march over to Olivia, remove the prong thing, rip off the electrodes and say, "You know what? Give the twelve stages of grief a shot first."
Anyway, Astrid takes out her bookstore purchase, which is a bible. Peter doesn't elaborate; he just starts talking about how the last time she was in the sensory deprivation tank, she went into a state of shared consciousness with agent Scott, which was when some of his memories crossed over into her brain. It makes perfect sense! "By putting you into a state of deep hypnosis, and by giving you substantial doses of psychoactive drugs, I can help you to access those alien memories that your mind has repressed." He tells her that his voice is her guide: "But it is also your tether to reality." See, that should really be a red flag to Olivia: Walter Bishop saying the words "tether to reality." He tells her to focus on his voice, or she risks getting lost in the memories. Then he says, "Uh-oh..." Olivia's all, what? "I just got an erection," he says. You're not supposed to tell her, you dingbat! Walter notes Olivia's eyebrows are raised halfway to her scalp and tells her that it has nothing to do with her "state of undress," which I'm not sure makes it worse or better: "I just simply need to urinate." He gets a boner when he has to pee? Isn't that inconvenient? I mean, if I remember my junior high health classes correctly, doesn't the, um, standing at attention prevent seeing a man about a horse? "That's good to know," says Olivia, dryly, and Walter blithely goes back to some equipment and asks Astrid to get her in the tank. Yeah, and make sure she's got the correct prong in her, Astrid, if you get my meaning. She asks Olivia if she's sure about doing this again. Olivia lies back in the water and says she just wants it to stop, and if John's memories can do some good, then at least she wasn't deceived for nothing.
Walter, injecting something into her IV, tells her that she's going to feel sleepy and reiterates that she needs to listen to him at all times. "Concentrate on the name of the man from whom you seek the information. And look for signs," he says. Olivia asks what kind of signs. Walter waits a long moment before answering, then says, "I'll tell you when you get there," he says, rather gravely, so it's probably nothing as benign as hobo symbols carved into fenceposts. Already sounding sleepy, Olivia asks what the bible is for. As he stands above her, hopefully not hoisting the mainsail anymore, he says, "Well, you're taking untested psychedelics, lying in saline with an electrical charge in the base of your cranium. Among other things, I thought it appropriate to pray you don't get electrocuted." It's not too late to get the hell out of there, Olivia! She quietly says, "Praise the lord," and Walter says "Amen," and closes the doors.
After a commercial break, Astrid's reading from the bible: "Then I will sprinkle clean water upon you," and Walter continues, from memory. Hey, isn't there a computer that Astrid could be monitoring instead? Astrid's impressed with Walter's knowledge of scripture, and says she didn't know he was so religious. "I'm not. Not anymore," he says. After puttering around and making marks on some readouts, he asks Olivia if she can hear him. She can. "You see the end of the escalator, Olivia?" He says she'll step off in five, four, three, two, one. We swoop into the tank as Walter tells her to look around, and asks what she sees. She doesn't see anything but light. But she does hear music. "Where is it coming from? You should be able to see something," he says. Nothing yet, says Olivia.
And we see what she sees: just a light haze. Walter tells her to stand by, and he pushes a button and adjusts a dial on the Brain De-Fogger 3000. Gradually shadows emerge from the haze, and shapes, and we see a door. Walter tells her to walk through it and tell him where she ends up.
She goes through, and then immediately up some stairs into a restaurant. "I'm in Goodfellas," she says. Actually she just says she's in a restaurant. Walter asks her if it looks familiar. It does, but she can't put her finger on it. Then she realizes it's the restaurant where she and John had their first date. And there they are, sitting at a table. Walter asks if she can see herself and John, which is when Peter comes in, asking what's going on. Oh, now you're curious. He's alarmed to find out Olivia's gone back in the tank: "Walter, you said that this was dangerous." "Oh, it is, very," says Walter, rather non-reassuringly. Astrid tells Peter that Olivia thinks John's got information about Walter Young. "So what? She went back in the tank to go talk to John Scott?" he snaps. "To see his memories," says Astrid, in a tone of voice that could best be described as "duh."
In the memory, Olivia watches herself and John chatting amiably. "So real," she says. Walter tells Peter he needs to adjust the drugs, which he'd "rather be taking [himself]," because he really has NO interest in allaying anybody's fears.
In the memory, First Date Olivia gets up and leaves the table, walking past Memory Trespasser Olivia, without so much as a glance. Walter tells her not to worry, as John can't see her.
Which, of course, doesn't stop her from trying. She sits at the table and says his name. He doesn't respond. Walter, admonishingly, tells her that he can't hear her and speak to her. "Olivia, I'm going to take you elsewhere." But Olivia wants to have a moment anyway. "I loved you," she says, and rambles on about how she loved him even then, during dinner, but he was lying to her about who he was. "Did you ever have any feelings for me at all, or was it all just...?" John sets down his wine glass, and Olivia clams up for half a blessed second before continuing. "Mark Young killed himself yesterday," she says, at which point he turns and looks directly at her. "He sees me," says Olivia. "No, Olivia, he definitely does not see you," says Walter, who can't see John staring right at her, half smile on his face. He doesn't say anything, and a second later Olivia is suddenly somewhere else: John's car. Alone, with John nowhere to be found. "It's his memory. He must be there somewhere," says Walter.
Olivia gets out of the car, and in a neat effect, Olivia is sharply in focus while everything else is blurry. It's like the reverse of those Claritin commercials.
It's dark, and she makes her way through wha
