Teaser Edit

The USS Discovery is being repaired as Saru goes to the transporter room to meet Michael Burnham. He's shocked to find Philippa Georgiou and quickly declares her presence to be classified to all there, including the operator, and her confined to quarters. He's then called to sickbay and he brings Burnham to discuss. She apologizes for bringing her back. They need to fix the ship for the coming confrontations they will have. He informs her of Ash Tyler's condition and asks her to try bringing him out of his condition, bringing the Human personality up front. She can't face him, and declines. Saru enters and is informed that there's little evidence of the Klingon side, but he's neither human nor Klingon at this point.

Saru talks to Tyler. He admits he can access Voq's memories and explains it was a program to infiltrate Starfleet. Voq and L'Rell hoped to take Discovery and, by doing so, draw followers. Saru asks for more information, and Tyler complies. He seems troubled at killing Hugh Culber and thinks he should be in the brig, but Saru considers it not his fault. However, he does have Tyler wear a monitor.

Saru, back on the bridge, sees that they're encountering a ship. Soon, they are boarded – led by Katrina Cornwell and Sarek. Cornwell immediately overrides the computer without explaining and Sarek mind melds with Saru, confirming he is as he appears. He also confirms that Lorca is dead.

Act One Edit

Cornwell is shocked at learning the full truth of Lorca's deception. She had seen the Discovery was destroyed nine months prior, and Saru explains it was the ISS Discovery. She realizes her real Gabriel Lorca has been dead. She then recounts the history of the war, mostly a losing one. Burnham notes there's no logic to the targets and Sarek explains each Great House is out for itself, fighting Starfleet for dominance without unity. Cornwell orders all information about the mirror universe deleted from the ship, as the enemy cannot get that information. Paul Stamets explains they ran out of spores so they'll have to use warp drive. Cornwell orders them to starbase 1. Burnham also informs her of the Emperor.

Cornwell and Sarek meet Georgiou. When they ask her what she knows, she says she wants to go back to her universe, whereas Burnham asks for political asylum. Cornwell says they can't anyway, besides being in the middle of a war.

Tyler is now free about the ship. He runs into Stamets and, after a tense moment, apologizes for Culber. He remembers doing it, and insists it sickens him. Stamets briefly tells him Culber was a good man and walks away. Tyler then goes into the mess hall and everyone quiets down. He gets his food and sits alone. Tilly then decides to sit with him, and eventually the others do, too. Tyler says they don't have to do that, but they stay put.

Saru is on the bridge as they approach starbase. Cornwell takes command and is informed that they can't get in contact. Indeed, after coming out of warp, they find the starbase destroyed, with the House of D'Ghor sign on it. 80,000 people dead. Cornwell is shocked. They are soon scanned and Saru has to order to ship to retreat. Cornwell falls into her chair and Saru reminds her for orders. She wants to contact Starfleet Command and heads to the ready room.

Act Two Edit

L'Rell is approached by Cornwell and supposes they understand each other. L'Rell admits that T'Kuvma was wrong about humans not having courage. Cornwell then explains the situation to her: the Houses are winning the war, but not unified as she wanted. L'Rell is startled, but unconcerned, still believing the Federation must be destroyed for its mission of homogenization and assimilation. Cornwell challenges this, saying they are about equality. L'Rell reiterates T'Kuvma's teaching, and Cornwell calls him ignorant. She then asks L'Rell how the war will end. She replies that it won't.

Burnham meets Georgiou to say she'll be on the ship awhile still, but she doesn't care. She turns the conversation to Burnham's relationship to Sarek, and is surprised to find the same relationship she had to her Michael Burnham. Burnham wants to know how the Terrans defeated the Klingons, but Georgiou challenges her about her weakness, saving her when she couldn't save her captain. Seeing that this made an impact, she then turns to the Klingons, calling them a cancer, dividing endlessly. She recommends destroying them at their source, Qo'noS.

Burnham then goes to Cornwell with a proposal. Cornwell in turn brings it to the other Admirals. They're reluctant, as an attack on Earth is imminent and Qo'noS is uncharted. Cornwell has a plan, though.

Act Three Edit

The Discovery team plans their move: growing spores, jumping the ship into the inside of the planet, then using drones to map it. Stamets knows where to grow the spores, a moon Delta 2.

Sarek goes to meet Georgiou on her request. She notes similarities between the two Burnhams and then offers more information on the mission, since more will be needed. Sarek is reluctant, but he feels forced to take it. She demands freedom in exchange.

Sarek walks with Burnham on his way out to Vulcan to discuss Georgiou's additional plan. He doesn't inform Burnham, though, preferring to warn her not to regret loving someone, even if it turned out badly.

Burnham goes to engineering for a status report. Tilly says they're on time. Burnham admits she may not see Sarek again and feels different this time. Tilly relates her awareness of the darkness within her as she took command of the ISS Discovery, and noted she had to understand it. Burnham says she can't forgive Tyler, but Tilly says he needs her, noting there's no future for him now. She should at least talk to him.

Act Four Edit

Discovery arrives at the moon and ejects the mycilium in little pods. After awhile, the spores quickly grow.

Tyler ponders by himself and finds Burnham finally facing him. She won't approach him initially. Tyler apologizes for everything and insists Voq is gone. Burnham believes him, but still asks if it's really him, since he should have had her back earlier. He then accuses her of wanting an excuse to leave, which shocks her. She denies it, but then supposes it was true, saying it felt like it was him choking her earlier. He says he should be a spy by now, but the reason it didn't trigger was her. She's stunned, and views the planet, relating her emotions after the Battle of the Binary Stars. She then goes, saying it won't be easy to let him go.

Cornwell communicates with Sarek, informing that the spore harvest worked. Sarek says the Federation Council has approved the plan, having no choice. Cornwell makes a shipwide hail from the bridge, noting their situation and declares the mission to map Qo'noS. Then, she introduces their guide, Captain Philippa Georgiou, newly found with a backstory explaining her disappearance. Burnham is tense as Georgiou calmly takes command.

Memorable quotes Edit

"The Discovery's been through... an inconceivable ordeal."
"Then where the hell is her commanding officer?"
"Captain Lorca... is dead."

- Sarek and Katrina Cornwell

"Bastard! The Lorca I came up with was measured, he was reasoned. I couldn't have imagined..."
"That Lorca was an impostor from an alternate universe was not the most obvious conclusion. We were all deceived."

- Katrina Cornwell and Sarek, on Lorca's true colors

"We are at war. Logic dictates that each farewell may be our last. Do not regret loving someone, Michael."

- Sarek's parting advice to Michael Burnham

Production history Edit

Cast Edit

Continuity Edit

  • Admiral Cornwell, in her speech to the Discovery's crew, told them their visit would be the first to Qo'noS since Captain Jonathan Archer and the Enterprise crew went there "nearly one hundred years ago." Enterprise is known to have visited the planet only in the episode "Broken Bow", but since that visit took place more than a century earlier, it appears this is not the visit she is referring to.
  • It is revealed that the ISS Discovery was destroyed by Klingons after crossing into the prime universe, trading places with its counterpart. Starfleet has found the debris and presumed it was the USS Discovery.
  • Starbase 1 is revealed to be one hundred astronomical units from Earth (in the outer Solar system) and now under Klingon control. A Starbase 1 was previously seen in Earth orbit in the alternate reality. Three starships were lost and several senior Starfleet officers were killed when they took the starbase.
  • The Federation Council allows the mirror Emperor Philippa Georgiou to assume the identity of her prime universe counterpart to lead a strike against the Klingon homeworld to end the war.
  • The Klingon homeworld Qo'noS is revealed to be a series of caves, one even large enough to hold a Crossfield-class starship like the USS Discovery. In the mirror universe, Qo'noS is a blackened ruin.
  • It was stated that in the mirror universe the Terran Empire controls more territory than the Federation and has explored further than they have dared.
  • Starfleet highly classifies all information on the Discovery's visit to the mirror universe. This could explain how the mirror Jonathan Archer could find no information on the Terran Empire in the USS Defiant's 2268 database (nor did Starfleet warn the Defiant about it's known fate), meaning the Halkan incident was also so classified by Starfleet, though at some point it was declassified as Bashir told Kira he read about Kirk's crossover at Starfleet Academy, as stated in DS9: "Crossover".
