- Harvard is now a secret observer installation. But Walter remembers a secret entrance that will give him access to his lab and perhaps a way to recover his plan to rid the world of the Observers. Olivia gets a distasteful look at Observer interrogation methods as Etta questions a loyalist security guard in hopes of finding a way to restore power to the lab. As Olivia and Etta disagree on how to dispose of their captive they gain a greater appreciation of each others character.—David Foss
- Walter does not recall the scrambled plan in his mind; therefore he decides to go to his laboratory in Harvard to search for his notes. However The Observers took the place and turn into a secret facility. But Walter recalls a hidden entrance to a steam pipe tunnel that allows him and his friends to reach his laboratory. They are surprised by a loyalist security guard but they succeed to capture him. The guard Manfretti refuses to give the information about the means to restore the power to the laboratory and Etta interrogates him with a device retrieved from The Observers that turns him older. When Olivia sees the method, she feels lack of humanity in Etta's procedure and sympathizes with the tortured guard affecting them both.—Claudio Carvalho, Rio de Janeiro, Brazil
- Back in the field of memory, Etta the young child picks dandelions and Peter and Olivia enjoy a lazy picnic. Peter calls for her and as she runs toward him a building disappears from the skyline and Observers appear. Olivia gets up and races toward her daughter, but there's a flash of white light. Olivia remembers waking up after the blast in triage. Peter looks around for Etta and gets more and more frantic as he can't find her.
In the future/present, Peter wakes Olivia up from her nightmare. He reassures her that the family is back together, even thought it feels like it all just happened a few months ago.
In the kitchen, they find Walter with the thought unifier strapped to his head. It's having adverse effects, he's talking out of sequence. But he's determined to keep trying to retrieve the plan to defeat the Observers from the depths of his memory. He lapses into Swedish.
Olivia comes in and asks Walter if he might have written it down. Etta explains they can't get into Harvard, it's been taken over by Observers. "Well that's not a problem for someone who's done acid," Walter says. They can use the steam tunnels for access.
He leads the group to an access point outside the barricade around Harvard. They race through a tunnel, dodging hot bursts of steam. They come out near the lab and make their way inside. It's covered in cobwebs, and half of it is in amber. Walter assumes he did it to protect it.
He sees his Betamax recorder on a tripod inside the amber. "I don't think I wrote anything down, I think I was making a video," he says.
They hear a door open. A guard comes to investigate. They cuff him and go through his things finding, among other things, a bag of bread crumbs. He's Gale Manfretti, a Loyalist. They decide what to do about him and wonder how he happened on the lab.
Walter decides he needs a laser and Olivia suggests he make one. They need to turn the power on from the sub basement of the science building. They wonder what they'd be walking into.
Etta points out Gale would know. She shuts the door and starts to interrogate him. She takes out a device that he recognizes and is afraid of.
She put a probe on each of his hands and asks him what the science building is used for. When he doesn't answer, she zaps him and he writhes, phasing in and out of time. He seems to age 20 years. "I don't think you want to waste any more precious time," she tells him.
In the lab, Walter destroys a laser disc player for the laser. Olivia notices pigeons flying through the lab.
Olivia wonders what Etta is up to with Gale the guard. She checks on him and finds Gale is an old and wizened.
Etta explains it's an Angel device, it stirs up the atoms in his body and can age him 25 to 30 year on a full charge. The idea is that he gets so disoriented he loses the will to lie.
Olivia goes to give him water, but Etta says it'll kill him. Etta defends her methods, saying that loyalists aren't worth crying over. "This is war, and we're losing," she says.
Walter calls Etta for her necklace, he wants to melt down the silver for solder. Etta hands it over.
Gale tries to convince Olivia that people will come looking for him, but she doesn't buy it. She takes out his bread crumbs, she thinks he came to feed the birds and isn't even supposed to be there. Olivia urges Gale to talk before Etta takes more years off his life.
"I'm trying to help you," Olivia says. "You don't have the authority to do that, do you?" he says. "You know a Loyalist doesn't just walk away when they've been captured by the Resistance."
"How can you be so sure?" she asks. "Where are you from? You're new to the Resistance," he says.
He tells Olivia he knows he won't survive this so he'll tell Etta what he wants to know if Olivia agrees to tell his son he's not coming home. He doesn't want his son looking for him when he's not coming back .
Etta comes back in the room and Olivia gives him her silent agreement. Before Etta can dial the device back up, he tells her that the main power is still in the building and everyone has an access code. There are rumors of experiments in the building.
He gives them the numerical code, but mentions there's an ocular scanner. Walter is appalled by the Angel device, which Etta says the Observers invented and the Loyalists use.
He examines Gale's eye, which is cloudy with glaucoma. He calls for a scalpel and a spoon.
Later, Walter dissects the cornea of an eyeball. He flubs it and calls for another. He's working on a pig's eye, looking at a close-up of Gale's eyeball to copy it.
Olivia traces a Loyalist bar code onto Peter's cheek, lamenting the state of the world. Etta's up next. She thanks her mom for agreeing she's the best person to go to the power station. "I know you like to be in control, so do I," Etta says.
Peter, in Loyalist uniform, and Etta, walk through the halls of Harvard.
Left alone with Gale, Olivia has questions. "Why does someone join the Loyalists?" she says.
"Pain," he says, telling her about one of his children dying in a Resistance explosion. After that, he just wanted to be safe. He was angry at the hopeless Resistance. As a Loyalist, he doesn't have to worry about the safety of his other son. He tells Olivia the world would be a safer place if the Resistance just stopped trying to fight.
Etta punches in Gale's code and Peter holds up the pig's eye for the scanner. It passes, but security wonders why he's in that sector and radios him. Olivia hears his walkie and holds it up for him, feeding him lines. Peter and Etta wait outside the door. Gale makes up a good enough excuse that security lets him in.
On the other side, Peter and Etta sees experiments being performed. Etta sees the dismembered head of her friend and former boss Simon Foster (Henry Ian Cusick).
She pulls out her gun to charge the room and Peter has to hold her back, reminding her to focus on the bigger picture. "There will be a time for vengeance, I promise," he says.
Back in the lab, Gale sincerely asks Olivia if she thinks they can win. "We have to win, so that all the people who died, including your son, didn't die for nothing," she says.
Peter punches things into the mainframe to reroute power to the lab. Walter and Astrid get started using the laser to free the Betamax.
Peter and Etta return to the lab. Etta wordlessly goes into Gale and releases his cuffs, she tells him he's traveling.
She plans to turn him over to the Resistance and let them get whatever they can out of him. She tells Olivia that Gale doesn't have a son and only gave her the code because he saw weakness in her and thought maybe he could convince her to let him go. Olivia tries to talk to Etta.
"You don't know my world," Etta says. "You're right, but I hoped for you, that where ever you were, that you weren't hardened by what happened to you. It's not that I don't see what the Observers have brought, I do, but what concerns me more is what they've taken away," Olivia says.
"This is the world. It is what it is," Etta says. She leaves Olivia alone with Gale. He gives her his address and son's name. She says she'll keep her word.
Etta goes to Walter for a sedative, then takes Gale away.
Peter frees the Betamax from the amber.
Etta drives Gale out to a field. He confesses he doesn't have a son, he hoped Olivia could convince her. He says he became a Loyalist because he's a coward.
She lets him go. He promises to help the Resistance, pointing out there aren't many Resistance fighters with an active tat ID.
He saw a certainty in Olivia that he's never seen before. "I felt, for the first time, that we were supposed to win," he says. He asks why she's letting him live.
"Something that I saw in her eyes as well. Pity," Etta says.
Walter takes the cassette out of the player. The laser might have damaged the tape. They press play.
Walter addresses whoever is watching, saying he's documented all the parts of the plan on video tape and they have to retrieve all of them to follow the plan. "If successful, this plan will restore us and rid the world of the Observers," he says.
Olivia's phone beeps. She pulls it out and sees video of Gale going free. Etta says she's on her way back. Taped Walter says "you are humanity's only hope." He tells the watcher to go retrieve the first tape, then he deploys the amber.
