Once again, I will highlight the traits common to both Olivias.
On the way to meet his father at Liberty Island, Peter sees, first hand, signs of various Fringe Events over the decades, thin spots, spatial distortions, wormholes, etc. We can see quarantined zones encased in amber on a greater scale than what was in "The Ghost Network".
Picking up where part 1 left off, William Bell helps Olivia reach Walter before The Secretary's people can get to him first. It is at the hospital, where Fringe Agent Olivia Dunham watches in shock as her double crosses the screen in the surveillance footage.
The rest of the episode mirrors the pilot in some degree.
Walter and Bell make haste to the Harvard lab to get a particle accelerator they need to use as a doorstop to keep open the crack at the opera house.
Olivia heads off alone to look for Peter. She goes back to Agent Dunham's apartment, hoping to enlist her help, by appealing to her sensibilities. "I'm you." Perhaps she has not shared the same experience or maybe because she's on The Secretary's side. She turns on Olivia now. I will always remember that in "Reciprocity", Olivia declares, "We're the same." Olivia knocks out her double, and after a quick transformation, assumes her identity.
In an eerie echo from the pilot, this world's Charlie Francis comments on recent events.
This job isn't what it was ten years ago. You’ve got alternate universes. I mean, it just -- just wasn't part of my training, you know? I mean, how are we supposed to fight these people? Truth is, Livvy, this makes me feel obsolete, you know?Peter discovers a connection he has with the machine. Only he can activate this part of it. Just like it acts like how the machine acts like a magnet in Peter's presence. (Reciprocity)
In the ensuing melee of gunfire, at the opera house, there is a switch. Turnabout is fair play, right? No one is wise to which Olivia accompanies them back, since Bell provided the power they needed for crossing over.
The episode closes with Olivia imprisoned in a darkened cell, the same place The Secretary holds the other Agent Dunham in "6:02 AM EST", for conspiring against him.
Walter Stuck on Guilt
Walter is held responsible for the damage to this world. Secretary Bishop is firm in this belief. He tells Peter as much. Even William Bell tells Walter is to blame for the devastation he sees of the blight. Walter is only too willing to shoulder that blame, even fifteen years in the future.
She's A Lot Like Her:
|What's she like? ... She's a lot like you.|
Differences and Similarities:
- William Bell died as a young man in a car accident.
- Massive Dynamic was never created.
- Olivia's mother is still alive, but Rachel died during childbirth.
- If The Secretary failed to find a way to cross between universes, how were the shapeshifters sent over?
- The Secretary can extract Peter’s DNA from infant Henry to power the machine. Is there no part of his genes that is compatible with Peter?
- In part 1, James Heath said that Walter was exactly the same as he remembered. William Bell says Walter asked to have parts of his brain removed, because of what he was becoming. We have seen a man driven to succeed and obsessed. Was Bell being honest?
Who would be left to power the machine?
No one would be taking a walk in the other's shoes.
Olivia would not find out for herself that people in the other universe is not her enemy.
