Plot

Multiple earthquakes are happening simultaneously around both our world and the alt-world. Walter believes he knows what the end game of David Robert Jones is. And, even though Olivia has a connection to one of the players Jones is using that she thinks she can utilize, in the end it leads to some hard decisions for the Fringe team.—kamas716

When earthquakes happen in several locations at the same time in both universes, the Fringe Division is sure that David Robert Jones is the responsible for the events. Walter explains that Jones is trying to synchronize both universes to destroy them both. Soon they discover that the criminal is using the former Cortexiphan children to achieve his intent. The Fringe Divisions of both universes that if they do not stop Jones they will need to shut-down the former Doomsday Machine and close the bridge, separating both universes. Further, Walter is worried about what might happen to Peter.—Claudio Carvalho, Rio de Janeiro, Brazil

Walter leads a presentation to the teams from both worlds. He thinks he's found out what David Robert Jones is up to: he's trying to collapse our worlds.

They would combine and create a big bang, mutual destruction on both sides. He would do it to create another universe where the laws of physics and nature are controlled by him.

It came to Walter in a dream. This makes some of the other Fringers skeptical, but Walternate suggests they consider it.

Sydney, Australia. A woman follows a map to precise coordinates, wearing a clock counting down past one minute. A man does the same in Bejing, China and another woman in the Himalayas, Nepal. In Manhattan, another man does the same.

They follow their maps to the locations -- on a rooftop, in a stream, in the middle of the street and shut their eyes and wait. The universe starts vibrating around them, the veins in their foreheads bulge. The ground cracks under the man in NY.

Peter reminds them about the destruction of Westfield, where one part of town was protected. Walter thinks DRJ has built a safe zone where he and his creations will be safe.

Walternate gets a message from command and leaves the room. Everyone else gets calls shortly after.

Multiple reports of earthquakes all over both worlds.

Fringe Division, the Other Side They all started at the same time and were between 5.7 and 7.1 on the Richter scale. The 27 locations of the quakes were the same in both universes. Fauxlivia thinks he must have had an amphilicite trigger.

Our Side Walter examines shoes from the epicenter in the earthquake in Manhattan. They vibrate at the key of E -- not the frequency of either universe. He thinks Jones is trying to tune the two universes. The vibrations are weakening the barrier between the two universes. If he does it enough times in the right locations, collapse is inevitable.

At Fringe Division Lincoln gets a visit from a childhood friend named Nick Lane (a childhood friend of the other Lincoln). He had a vision of the earthquake but didn't know it was actually happening.

Harvard They have footage of the woman in Sydney, standing still as everyone else runs. They wonder if she had a device on her to trigger it.

Olivia gets a call from Lincoln, at the bridge. He tells her about Nick's vision and that it sounds like he saw our side, not the Other Side where Nick is. He described a Manhattan without the Twin Towers. Olivia recognizes the name.

She looks at the video from Sydney again and realizes it's Sally Clark. Sally and Olivia and Nick were in the Cortexiphan trials together. David Robert Jones isn't using amphilicite, he's using Cortexiphan subjects as the devices.

Walter explains: Nick and the Cortexiphan kids are using their alternates to draw on their frequencies to merge the universes. Peter wonders if the connection between the two universes is facilitating what they're doing. Peter suggests closing the bridge, shutting down the machine. That would also stop the healing on the Other Side.

Olivia has another idea.

Fauxlivia brings Nick to the bridge and then to Walter's lab. Walter injects him with Cortexiphan. The idea is that amping his up will help Olivia locate the Nick on this side who's participating in the earthquakes. They link the two of them with forehead wires. Olivia watches Nick pass the Newbery/Rockpoort train station. Peter and Lincoln head there with a team.

Olivia sees that Nick has a map and is looking for something. She sees him on the Salem Bay University campus. He's standing in a quad and looks at the timer counting down past 15 seconds. He's going to trigger another earth quake.

Peter sees him and the teams converge. They get him but in the lab Astrid can see reports of seismic activity from around the globe.

Nick sits in holding. He has a scar on his forehead. Broyles tells the team the quakes are causing fluctuations in the earth's magnetic fields. They have Nick's watch, the tech is from the Other Side. They wonder how many more quakes it'll take to collapse the universes. Walter is surprised it hasn't already happened.

Broyles has been called to Washington, they want to discuss shutting off the machine.

Olivia wants to interrogate Nick Lane. She immediately asks him where David Robert Jones is. Nick says he can't tell her. He tells her they're on the same side. He reminds her about what they prepared them for as kids. The war they warned them about is happening. He says Jones is on their side and is protecting them. Watching, Walter figures out what he's talking about.

Nick only works with Jones, he doesn't know the others. He thinks the damage the earthquakes are causing on the Other Side will destroy it. He says there's one more offensive left and the Other Side will surrender. Olivia tells him Jones is using him and there is no war.

Peter takes apart the timer on the Other Side. He talks about closing the bridge with Lincoln. He would at least appreciate that things would go back to normal. He would stay on our side, he tells Lincoln, saying he's come to believe that home is where the heart is.

They notice the timer has reset. It's counting down from 6 hours.

In holding, Olivia brings it to Nick, telling him that in six hours, everyone he loves may cease to exist. She says he's the only one who can stop it from happening. He tells her about having bad thoughts in college and that he had to make it stop. He was going to kill himself and had the knife in his hand when his parents called. His sister had just slit her wrists, his emotions have reverse impact.

David Robert Jones found him three years ago telling him he needed warriors. DRJ taught him how to channel his power and control it.

Olivia tells him she's worked with the Other Side and they're not our enemy. She tells him about closing the bridge and that he can help all those people.

Nick helps them. Walter tells him their theory about DRJ's plan to create a safe zone with a force field. Nick says DRJ usually came to him, but one time he met him in a warehouse. He takes them to it.

Teams go in. They hear a loud mechanical noise.

In the car outside, Nick is nervous and antsy. He tells the agent with him that he's pathetic for not questioning DRJ, that he should have just killed himself. "You feel that don't you?" Nick asks the agent.

Inside, they find nothing. They get called back outside, where the agent has stabbed himself.

Nick escaped.

At the bridge conference room, the clock is at 47 minutes. Broyles says Washington is leaving the decision up to the people in the room.

Walternate and Walter agree they have to close the bridge.

At the machine, Peter connects to it and initiates a system overload. The power will surge and they'll shut it down.

Walternate tells Walter that Peter is remarkable, smart and noble, all the things he would have wished for him. Walter excuses himself but Walternate finds him in the hallway.

"I know what you're afraid of. It occurs to me, so I know it occurs to you to: If the machine stops working, Peter may disappear," Walternate says.

"I believe it brought him here, I believe it may take him away," Walter says.

Walter has come to accept that Peter isn't theirs.

The overload is near. Lincoln finishes talking to Broyles. Lincoln reminds Peter what he said about home being where the heart is, then he looks at Fauxlivia. He thinks he's found his.

Fauxlivia tells Olivia there's a lot about her she admires.

Lincoln joins the other team. As the machine nears overload, Walter prepares to shut it off. The teams face each other.

It's time.

He shuts it off.

The room shakes, the machine blurs and on our side, the Other Side disappears.

Peter is still there. Walter tells him he'll miss them.

(Eight minutes remain on DRJ clock.)
