RECAP | Star Trek: Discovery 505 - 'Mirrors'

No matter how bad things get, the one thing you always have is a choice.

SPOILER WARNING: This article contains story details and plot points for Star Trek: Discovery.

Previously, in "Face the Strange," Moll and L'ak unleash a time bug aboard the U.S.S. Discovery, designed to paralyze them and keep them stuck as they're randomly cycled through time. Once they're ahead of Discovery and on to the next clue, they can escape the bounty on their heads and finally be free.

In one time loop, Zora informs Burnham and Rayner one of the outcomes they feared had come to pass — the Breen gained control of the Progenitors' tech and destroyed everything, leading the Kellerun to believe the Breen must be the ex-courier's highest bidder. Thankfully for the crew, they're back in the mix and only lost six hours. Plus, they discovered a warp signature matching Moll and L'ak.

In Episode 5 of Star Trek: Discovery, "Mirrors," Captain Burnham and Book journey into extra-dimensional space in search of the next clue to the location of the Progenitors' power. Meanwhile, Rayner navigates his first mission in command of the U.S.S. Discovery, and Culber opens up to Tilly.

Star Trek: Discovery Season 5 Section Banner - Event Log

In his quarters aboard the U.S.S. Discovery-A, Cleveland "Book" Booker contemplates advice given to him by his mentor and namesake, "No matter how bad things get, the one thing you always have is a choice." Book gazes at a holo of Moll — real name Malinne Ravel, the daughter of his predecessor — certain that she is capable of turning things around just as he had. Aware that Cleveland Booker IV saved his life, Book believes he owes it to him to do the same for his daughter.

With Discovery at Moll and La'k’s last known coordinates, Book makes his way to the Bridge, where Captain Michael Burnham gives the stage to Commander Paul Stamets and Lieutenant Sylvia Tilly. Though it appeared as if the couriers' ship left a warp trail which disappeared into empty space, adjusting the viewscreen to compensate for the Lorentzian coefficient in high-energy spectra reveals the presence of a fluctuating wormhole. Stamets states that it leads to a pocket of interdimensional space and is collapsing and expanding due to matter-antimatter chain reactions, likely caused by the Burn.

Captain Burnham surmises that the next clue resides within the wormhole, and Tilly notes that Moll and L'ak are probably in there, as well. Lieutenant Gallo, Commander Rayner, and Lieutenant Christopher brief the captain — sensors can’t penetrate the aperture, the opening isn’t large enough to fit Discovery’s saucer, and there’s no guarantee that they’ll be able to maintain comms contact. Burnham nods, ordering Lieutenant Linus to prepare a shuttle with boosted comms and fortified shields before requesting that Lt. Commander Gen Rhys place a security team on standby.

Rayner narrows his gaze towards the viewscreen ahead of him on the bridge of Discovery as Rhys and Linus stand behind him at their stations in 'Mirrors'


The captain's declaration that she will accompany Book on the away team draws Rayner's interest, and the two senior officers convene in the Ready Room. The Kellerun first officer expresses his view that he should be the one risking his life to lead the mission. She assures Rayner that she needs him on the ship and refuses to bring additional security with her, citing that the implied threat of armed guards would undermine Book's personal connection to Moll. Recalling the devastating future they had witnessed during the time bug ordeal, Rayner observes that it was only one possible outcome.

Captain Burnham senses there is more to Rayner’s unease and quotes the Ballad of Krul, "Serve it without a grum of osikod." Though impressed by his captain's reference to Kellerun culture, Rayner still holds back. Burnham theorizes that his concern is related to taking the conn while she's away, and he begrudgingly admits it has been some time since he took the chair from another captain. The first officer makes eye contact, confessing that he doesn’t want his tenuous rapport with the crew to jeopardize the mission. Burnham reassures Rayner that she believes in him, leaving the demoted captain to swallow his protest.

Book joins Burnham to embark on their journey and pilots their shuttle away from Discovery. Relaxation floods the former courier's expression as he notes the craft is "purring like Grudge when she’s killed something." Hoping to emphasize his connection to Moll's father in the event they locate her, Book playfully shifts the conversation to the captain's temporal escapades when the time bug overtook the ship. Burnham makes a "my lips are sealed" gesture, only willing to disclose that she encountered some surprises.

Burnham looks over at Book while navigating a Discovery shuttle in 'Mirrors'


The shuttle approaches the aperture, and Book plans to charge the impulse capacitance cells and release them into the drive coils to give the vessel a boost. Book offers a saying from his own culture, Never return from a hunt without enough bait for the Carrion Reaver. Burnham laughs off the "catchy" phrase, and the shuttle launches toward the wormhole's pulsating light. Turbulence causes the ship to tremble, and a bright flash overwhelms the two occupants.

Commander Rayner observes from the Bridge and is initially greeted by static. Burnham's voice cuts through the interference, informing the first officer that they made it through. Rayner’s relief is short-lived, as Discovery loses the shuttle's comm signal. He orders Stamets to the Science Lab in a bid to boost comms and conveys confidence as he takes the ship to Yellow Alert.

Meanwhile, in the wormhole, exotic matter has rendered the shuttle's sensors and holopadds inoperative. Book and Burnham narrowly dodge debris — "debris is not a good sign" — and spot the smoldering wreckage of Moll and L'ak's ship, or at least half of it. The nebulous environment clouds their vision, and Book wonders if the couriers survived. Burnham stands as she spots another vessel through the murkiness, its I.S.S. markings indicating it originated in the Mirror Universe. Shock envelops the captain's face as she reads its full designation — I.S.S. Enterprise* — and postulates that how the vessel arrived in interdimensional space must be "one heck of a story."

Book sees the Constitution-class starship's battered hull as evidence that it became trapped during a battle, and Burnham declares that it must have been ages ago — crossing from the Mirror Universe has been impossible for centuries. A shipwreck in a hidden wormhole sounds like a secure place to hide the next clue, though the captain is only acquainted with her brother Spock's U.S.S. Enterprise. They glimpse the other half of Moll and L'ak's broken vessel and assume that, if the couriers are alive, they must be on the Terran ship.

In Sickbay, Tilly kneels down as she tracks a conduit in a panel as she looks over her shoulder at Hugh Culber in 'Mirrors'


Back on Discovery, Tilly tracks an EPS conduit to a panel in Sickbay — after having followed it across three decks, including through the quarters of a new ensign who keeps a Cardassian vole as a pet. Sensing that Dr. Hugh Culber feels troubled, Tilly lets him know that she's always available to talk — at least until Stamets chimes in over the comm system to check on the status of her work. Culber maintains that he is fine and promises to find Tilly later, though his demeanor leaves her unconvinced.

In the Science Lab, Stamets notices that Ensign Adira Tal is undergoing some uncertainty of their own while working on their graviton pulse idea. The ensign rechecks their calculations for a third time, prompting the astromycologist to tell them that the time bug was not their fault. Rayner strolls in with confidence and requests an update on attempts to boost the comm signal. Stamets begins to explain, but the commander interrupts and states that he does not need to know how the cake is boiled. Adira is taken aback by the Kellerun culinary insight — Rayner assures them not to knock it until they try it — but Stamets presses forward with a proposal to hold the interdimensional aperture open. Unfortunately, there's a 43.7% chance that a graviton pulse would cause the aperture to close with the captain and Book still inside. Visibly frustrated, the first officer urges them to get the comm signal back.

Phasers drawn, Captain Burnham and Book enter the I.S.S. Enterprise's bridge, which is adorned with Terran insignia and dimly illuminated by flickering lights and control panels. Intent on using the ship's sensors to track quantum signatures from the Prime Universe in order to locate Moll, L'ak, and the clue, Burnham pauses when she realizes that Book is standing at the science station — her brother's station, at least on the U.S.S. Enterprise. Though she had never met Spock's Mirror counterpart, she assumes he was just as ruthless as the Terrans.

Using a hack Book had previously applied on an Andorian transport ship, the captain successfully accesses the Enterprise's sensors, and — after the former courier elicits words of praise from her — they detect that the intermix chamber has been ejected from the warp drive, all shuttles and escape pods are gone, the captain's log was erased, and the crew had apparently abandoned ship. Evacuation is a last resort in Terran culture, but the starship's damage was not terminal. The situation leaves them puzzled, but they turn their attention to the three Prime quantum signatures located in Sickbay — Moll, L'ak, and the clue.

En route to their quarry, Burnham and Book spy bedding, blankets, clothes, and other objects one wouldn't expect to find on a warship strewn about in the transporter room. Book gets a glimpse of the I.S.S. Enterprise's dedication plaque, which itself bears an unorthodox phrase for Terrans, "Light of hope shines through even the darkest of nights." The inscription describes the starship’s story, and Book relays that the new Terran High Chancellor had been killed while trying to make reforms. The crew mutinied, escaped, and attempted to shuttle refugees from the Mirror Universe into the Prime Universe, and a Kelpien slave-turned-rebel leader helped them. As she listens to the tale, Burnham picks up a locket and places a piece of her uniform inside of it. The mention of the Kelpien — likely Mirror Saru — catches her attention, and she supposes the crew fled when the ship got stuck within the aperture.

Moll and L'ak stand directly across from Book and Burnham, all tense with phasers drawn, in Sickbay of the I.S.S. Enterprise in 'Mirrors'


The pair continue on and move through the Terran ship's sparking corridors, only to be confronted by a batch of Moll and L'ak holo-doubles whose phasers are pointed toward Sickbay's entrance. Unable to determine which Moll and L'ak figures are real or target the room's holo emitter from their location, Book and Burnham rush their opponents and dodge a storm of phaser fire. They take out several holographic doubles before striking Sickbay's emitter, and the two couriers' true forms are revealed. Everyone heads for cover, but Burnham's diplomatic appeals don’t sway Moll or L'ak.

Book steps out from his concealed position. The captain follows with her phaser up, but Book tries to relate to Moll via their shared connection with her father. Moll grimaces with pain and anger as she states that Cleveland Booker IV was garbage, and L'ak holds up their bargaining chip — a device containing the next clue. Moll pitches a compromise; if she and L'ak are given a ride out of interdimensional space, they’ll let Starfleet replicate the clue. Burnham counters, bluntly replying that the couriers don’t have the clue. Referring to the decoy stanzas on Lyrek, the captain displays the locket she had procured and notes it has a Prime quantum signature.

The standoff remains steadfast, and Book draws Moll's ire when he guesses the couriers would not risk each other's lives over latinum. The exchange intensifies, and Moll contests that not even the Federation could lift an Erigah. Burnham recognizes the term, stunned to learn that the mysterious L'ak is actually Breen. An Erigah is a Breen blood bounty, and Moll and L'ak clearly hope to exchange whatever is at the end of the clue trail for their freedom. Book questions Moll about what they did to receive such a sentence, and the courier reflects…

…back to one of her regular visits to a busy Breen space station some years ago, where two helmeted Breen investigated one of her deliveries. Moll is unafraid when a third Breen approaches, introducing herself by quipping that she enjoys latinum and long walks on the beach. The Breen responds through his helmet's metallic speech processor, but rather than using the Breen sounds deemed unintelligible by most species, he speaks to Moll in her own language and accuses her of cutting her dilithium shipments with impurities. The human denies the accusation levied by "Green Eye," and the two square off in hand-to-hand combat.

Moll's lighthearted conversation persists even as they fight, and she points out that the Breen's belt insignia indicates he is royalty. Rumors have swirled that the Primarch's nephew — an independent thinker named L'ak — has been demoted to shuttlebay duty. Moll suggests that she can help L'ak get payback and admits she does cut the dilithium, leading the Breen to place her in handcuffs. Moll never relents, pitching that having a partner on the inside would make her operation go smoother. She senses L'ak is intrigued and faces him — she knows what it's like to be on the outside and alone — before slipping out of the cuffs. L'ak ponders why Moll would make a deal with someone she didn't know anything about, and Moll resolves to change that unfamiliarity.

Book looks towards Moll during a tenuous truce aboard the I.S.S. Enterprise in 'Mirrors'


Back in the present, Moll refuses to disclose what she and L'ak did to receive their bounty. Captain Burnham cautions them to not let love lead them down the wrong road, but Moll and L'ak opt to open fire once again. An errant phaser blast strikes a control panel, raising a containment field that traps Burnham and L'ak in Sickbay while preventing Book and Moll from re-entering the room. Book intends to resolve the dilemma with the Bridge's security controls and requests Moll's assistance. She agrees to the temporary truce, but threatens to dust Book if he makes one wrong move. They depart, but L'ak and Burnham stay put and keep their weapons drawn.

In another memory from their time on the Breen space station, L'ak receives payment from Moll and declares that her dilithium is clean. She quietly asks if he’d like to inspect her ship again to make sure she didn’t smuggle any tribbles on board, but L'ak's needs to shine his boots in anticipation of his uncle's upcoming inspection. The Breen clarifies that this isn't a euphemism, as the Primarch really likes their boots to be shiny. Moll thinks his uncle sounds like an asshole and brings up the promise that "Green Eye" had made during her last visit. L'ak delays, but Moll is adamant that he show her what he looks like. Though she has seen his face, she wishes to view his other face. L'ak seems self-conscious, and Moll maintains that both faces are a part of him. L'ak concedes, holding his breath and retracting his helmet to reveal his translucent green features. Moll greets him with warmth…

...however, aboard the Enterprise, Moll's demeanor is icy. She walks defiantly through the ship's corridors and rejects Book's appeals about her father. Aware that Cleveland Booker IV left Moll and her mother, Book shares that his mentor made the difficult choice to stay away from them in order to keep them safe. Moll emits a strained laugh, believing that Book must have his own "daddy issues" to have believed her father's story. Even though her father had promised to get his family off of Callor V and take them to a safe-haven colony in the Gamma Quadrant, he eventually just stopped coming home. Her mother was forced to get a job in the rubindium mines, ultimately falling victim to the harsh conditions when Moll was 14. Left alone, Moll tearfully emphasizes that L'ak is now the only person who matters to her.

In Sickbay aboard the I.S.S. Enterprise, Burnham and L'ak are locked on each other with phasers drawn in 'Mirrors'


Down in Sickbay, L'ak and Burnham retain their suspicious stares. Seated, yet still aiming their phasers at each other, they discuss the "power beyond all comprehension" that the Romulan scientist's diary and the subsequent clues would guide them toward. The captain warns L'ak what could happen if they Breen acquired that technology, and her observation that the Federation is all about second chances seems to resonate with him. Though Burnham promises she'd advocate for Moll and L'ak to serve their time together, L'ak is emphatic — he'd rather die than be separated from Moll.

On the Enterprise's Bridge, the security system's firewall prevents Moll and Book from accessing the containment field. Moll pounds the console in frustration, but Book takes the opportunity to compare Moll and L'ak’s bond with the one he had shared with Burnham. With the exception of Grudge, who bites him when he doesn't feed her, Michael was the first friend Book made after Cleveland Booker IV died. He apologizes for what Moll endured because of her father and explains his troubled relationship with his own father, though Moll's thoughts continue to drift to L'ak…

…and to their time on the Breen space station. Concealed by a force field among the cargo containers, Moll and L'ak kiss. The human pauses, hesitant to mention that she received a new contract in Emerald Chain territory. L'ak calls Osyraa a butcher, but Moll responds that the Breen Imperium's faction wars don't make this region much safer. Her pursuit of higher paydays is a byproduct of her desire to discover the peace and freedom of the Gamma Quadrant paradise that her father had described. L'ak confesses that he only stays in Breen space because he has nowhere else to go, prompting Moll to propose he leave with her. The sound of footsteps interrupts the tender moment, and the Breen Primarch marches in with two Breen soldiers by his side. He disables the privacy field, his visored face locking eyes with the human.

With the memory of that confrontation fresh in her mind, Moll comes to attention on the Enterprise's Bridge and knocks open a panel underneath the con. She creates a power surge to burn through the security system and short out the containment field, but her actions cause violent explosions to rock the ship. The Sickbay force field drops, though Burnham’s attempt to block L'ak's exit results in another round of fisticuffs that shatters glass and takes its toll. Book reports that impulse engines are overloaded and nav systems are fried — they have no control over the ship. Discovery's shuttle becomes dislodged, tumbling away from the Terran ship and leaving the Enterprise eight minutes from impacting the aperture.

Book tries to develop a plan, but Moll aims her phaser at him. Nevertheless, Book is still determined to not let anything happen to Burnham or Moll. As a Kwejian, he lost his planet — everything that he cared about is gone. Though Cleveland was a "shit dad" to Moll, he was a great mentor to Book. In a heartbreaking tone, Book informs Moll that she is the only family he has left. He carefully picks up his phaser but chooses to hand it to her. She reacts with suspicion and directs both weapons toward him. Moll wrestles with indecision but opts not to kill him, a choice which elicits a sigh of relief from Book.

Brawling in the I.S.S. Enterprise's Sickbay, Michael Burnham kicks L'ak in the chest in 'Mirrors'


Burnham and L'ak's physical confrontation rages in Sickbay, but the Breen's reliance on a bladed weapon proves to be a tactical error. The Starfleet officer subdues him and retrieves the clue — the locket was a decoy. However, L'ak was inadvertently stabbed with his own blade during the attack. Moll runs in at this unfortunate moment, filled with concern for her partner and rejecting Burnham's plea to get L'ak to Discovery for treatment. Now a mere five minutes from colliding with the aperture, Book and Burnham speed off to the Bridge, leaving Moll to assist L'ak in Sickbay…

…and remember the moment when the Breen Primarch caught them together. As a guard holds L'ak, a second Breen strikes Moll. The Primarch prevents his nephew from intervening, then airs his grievance — L'ak carries the genetic code of the Yod-Thot, they who rule. While the Primarch campaigns for the throne of the Imperium, L'ak has been consorting with "lesser beings." His uncle describes L'ak's use of his more humanoid face as an insult to his heritage. The Primarch retracts his own helmet, gesturing to his translucent visage and proclaiming, "This is Breen." L'ak argues that their ability to change is a sign that both faces are a part of them, but his uncle claims they have evolved past a need for that form — holding it makes L'ak unfocused, inflexible, and weak.

The Primarch reseals his helmet and hands L'ak a weapon. His nephew must kill Moll to gain redemption. Resigned to her death, Moll tells "Green Eye" that their relationship was fun while it lasted, but L'ak elects to shoot the Breen guards instead of her. His uncle allows L'ak to place the phaser at his chest. Swayed by the fact that the Primarch raised him, L'ak only wounds his uncle. Alarms blare through the cargo area, and L'ak urges Moll to flee so that he will know she's safe. The blood bounty that L'ak just earned does not dissuade Moll from wanting him to join her. Holding onto his face, she says they can be happy together. L'ak voices his love for Moll…

…which snaps her back to the present, where L'ak reiterates his love for Moll in the Enterprise's chaotic Sickbay. However, she is unwilling to give up and vows to get them out of this predicament. Meanwhile, Burnham and Book burst onto the Bridge and intend to activate a tractor beam. Book brightens the Terran light panels — "can’t save the day if we can’t see" — and winks at the captain as he takes the helm.

On Discovery's Bridge, Commander Rayner asks Christopher for an update on comms. Naya interjects, reporting that something is happening at the aperture. A tractor beam can be seen emanating from within the wormhole, and it is oscillating with a repeating pattern: 3-4-1-4. Rayner grins in understanding and calls Stamets, Adira, and Tilly to the Bridge. The first officer doesn’t just need them to hold the aperture open, he also wants them to make it bigger — large enough for a starship. Discovery isn't going in, but their captain is coming out.

On the Bridge, Tilly, Stamets, and Adira are all concerned look in different directions in 'Mirrors'


Stamets and the senior staff are perplexed by Rayner's announcement, and the Kellerun's reference to the Ballad of Krul doesn't give them any additional insight. Returning to the task at hand, Tilly affirms that such a procedure would require more energy than the entire ship can safely produce. Rayner pushes them for ideas, promising a cask of Kellerun citrus mash for whoever lands this solution. The Bridge is abuzz with chatter — inverting the deflector array would take too long, discharging the spore reserve would leave them unable to make an emergency jump, and pulling power from gravitational systems would cause everyone to float around… but replacing the photon torpedo payloads with antimatter would add fuel to the reactions already present in the aperture! Adira confirms that hitting it precisely with a sequential hexagonal pattern should keep it open for approximately sixty seconds. Rayner questions why it must be hexagonal, but Stamets points to him in a mischievous manner and notes, "It doesn’t matter. It’ll work." Satisfied, the commander awards the citrus mash to the entire Bridge crew and trusts that they'll make their only chance to succeed count.

As Captain Burnham sits in the I.S.S. Enterprise's center seat, the ship's computer pronounces that only 60 seconds remain until impact with the aperture. Driven by the perilous countdown, she confesses to Book that he was one of the surprises she encountered while ensnared in the time bug's grip. She reflects on how nice it felt and how happy they seemed. Book offers an appreciative nod, but the pull of the aperture shakes the Enterprise.

On Discovery, Rayner orders a volley of torpedoes to be launched at the wormhole, and their detonations cause the opening to expand and generate even more light. The Enterprise's tractor beam rattles the ship as it makes contact with Discovery. Book awaits Burnham's order to act and asks if he should "hit it." Captain Christopher Pike's signature phrase draws a quizzical and bemused look from Burnham, who replies, "Feels weird. Let’s just fly." The Terran ship's saucer section begins to emerge from the aperture, and its secondary hull clears it just before it collapses and releases a radiant surge of energy.

A relief-filled Captain Burnham communicates her thanks to Rayner over the comm channel, but she and Book then notify Discovery about a Terran warp pod being fired by the Enterprise. Scans detect two lifesigns and sickbay equipment aboard — Moll and L'ak. The pod launches and jumps to warp before it can be captured, though Rayner hopes to follow their warp signature and put out an alert throughout the fleet.

As the I.S.S. Enterprise and U.S.S. Discovery station themselves opposite one another in deep space, Rayner accompanies Burnham on a stroll through Discovery's halls and compliments her on her "3-4-1-4" signal. The captain's message had referred to Section 4, Verse 7 of the Ballad of Krul, in which Krul calls to his war brothers for rescue with a repeating drumbeat of three taps, followed by four, one, and four. Although impressed, Rayner has doubts about how the mission played out. Burnham encourages him to take the win and relays that she is ordering Commanders Owosekun and Detmer to head a team and fly the Enterprise back to Federation HQ storage.

Tilly with her arms folded while leaning at the bar table looks up towards Culber in 'Mirrors'


Discovery's crew takes some much-needed downtime in Red's, where Culber follows through on his promise to confide in Tilly. The doctor leans beside her at the bar, and Tilly remarks that the day has left her feeling as if she has been through a gormagander's digestive tract. Highlighting the unique experiences he's had — dying, being resurrected, and staying present in his own body while Jinaal Bix inhabited it during the zhian'tara — Culber can only classify these events as "weird." Coupled with their current quest to find the technology that created life, Culber has found these questions to be both impossible to grasp and exhilarating. Since Stamets hates the unknown, Culber isn't sure how to talk to his partner about these emotions. Tilly advises him that the intellectual and the spiritual are not that far apart in the sense that they each bring understanding and can take you to new places. Initially taken aback by Tilly's use of the word spiritual, the doctor lets his friend's words sink in.

Captain Burnham welcomes Book into her Ready Room as she finishes reading a file on the Progenitors. There's no news about Moll and L'ak's whereabouts, but every ship in the sector is on high alert. She extracts a vial of liquid from the device containing the clue and shares that Stamets is preparing to do a full chemical analysis on it. Burnham secures the third object alongside the other two clues, which Book observes always seem to be presented hand-in-hand with a lesson. The ordeal with the itronok on Trill demonstrated that they valued lifeforms different from their own and the necropolis planet evoked the importance of cultural context, so why did a scientist leave the third clue on a Terran warship? 

The query draws a smile from Burnham, who discloses that the scientist had been a Terran named Dr. Cho — the junior science officer aboard the I.S.S. Enterprise. The captain had Zora search for the names from the vessel's manifest, and most of them had turned up in various Federation databases. The crew did make it to the Prime Universe and started new lives, and Cho herself became a branch admiral in Starfleet. The Terrans had hope, found freedom, and overcame the odds. Burnham supposes that those qualities were the reasons Cho returned to the aperture and concealed the clue on the Enterprise. Perhaps the lesson is that they can shape their future in the same way the Terran refugees had.

Book catches sight of the Enterprise getting underway outside of the Ready Room's viewport, prompting the captain to turn and gaze at the vessel. She brings up the time bug secret she had shared with Book when death appeared imminent, but he grins and acknowledges that they had been happy. Stamets' voice rings out over the comm system to let the captain know he is ready for the vial. Burnham grabs the container and makes her way to the door, but Book wonders what happens when they finally put these clues together. Captain Burnham concedes that she doesn't know, but she can't wait to find out.
