5x02 Under the Twin Moons

[7.2/10] Star Trek: Discovery does a better job of telling the audience that a relationship is important than spurring us to feel that importance. Your mileage may vary, of course, but across the series, characters have these soulful conversations about how much they mean to one another, and it’s rare, if not unprecedented, for the show to have earned that emotion through lived-in dynamics and experiences that believably bring two characters closer together.

But Burnham (Sonequa Martin-Green) and Saru (Doug Jones) are one of the big exceptions. They’re the two characters on the show who’ve arguably changed the most over the course of the series. Michael went from disgraced mutineer to respected captain. Saru went from a timid, by-the-book stiff to a more open and adventurous officer. And,as is Star Trek tradition, along the way, through hardship and heroism, they went from being mutual skeptics of one another to trusted friends.

Where so many of the friendships in Discovery fall flat, Michael and Saru are among the few who play with the ease and care of genuine confidantes. So an episode like “Under the Twin Moons” comes with the power of (supposedly) being Saru’s last hurrah as a Starfleet officer and, more importantly, his final mission alongside Michael Burnham.

In truth, the mission itself is no great shakes. The latest break in the Progenitor case sees the duo beaming down to the planet of the week, a lost world protected by one of those ancient technological security systems that Captain Kirk and company seemed to run into every third episode. The art direction work is laudable, with some neat designs of the weathered statues and other remnants of the fallen civilization, and a cluttered jungle locale that comes off more real and tactile than most of Discovery’s more sterile environments.

But this largely comes off as video game plotting, even before the show reveals that the Progenitor mission is essentially one massive fetch quest. The sense of skulking around old ruins, avoiding weathered booby traps, and using special abilities to avoid obstacles and find clues will be familiar to anyone who’s played Jedi: Fallen Order from the other half of the marquee sci-fi franchise dichotomy, or even precursors like the Zelda series of games. The challenges the away team faces feel more like perfunctory obstacles than meaningful threats to be overcome.

Still, these obstacles accomplish two things, however conspicuously. For one, they show Saru’s value to Starfleet in his alleged last mission. He shoots down ancient security bots with his quills. He attracts and evades their fire with his superspeed. He detects the hidden code with his ability to detect bioluminescence. And he’s able to use his strength to move a large obelisk back and forth to find the last piece of the puzzle. On a physical basis, it’s not bad having a Kelpian on your side.

More to the point, he also looks out for Michael. There’s a nice low-simmering conflict between them, where Michael wants to save Saru so he can enjoy the bliss of his civilian life with T’Rina, and Saru wants to fulfill his duty as any other officer would and protect his friend. In an episode themed around frayed connections between people, it’s nice to see that tension play out in an organic, selfless way between these two longtime comrades. Their ability to work together to solve problems, figure out puzzles, and most importantly, put their necks out for one another (in some cases literally), does more to honor Saru’s place in the series than all the Kelpien superpowers in the galaxy.

For another, they give Tilly (Mary Wiseman), Adira (Blu del Barrio), and eventually Captain Rayner the chance to do something science-y to help Michael and Saru down on the planet. Granted, their “Why don’t we use an ancient electrio-magnetic pulse?” solution strains credulity a bit, and Rayner’s advice boiling down to “You need to think like an ancient civilization” isn’t that insightful. But it gives a couple of the show’s players something to do, and reveals, however ham handedly, not only Rayner’s facility in the field, but his willingness to help out even when he doesn’t have to.

That's a good thing, since he’s joining the cast as the new first officer (something portended by Callum Keith Rennie’s addition to the opening credits. The dialogue to get him there is clunky, with thudding comments from Admiral Vance (Oded Fehr) and Burnham about Rayner being a good man despite some poor choices born of tougher times. But after only a couple of episodes, Rayner is a welcome addition -- a fly in the ointment for a now-cozy crew, bolstered by Rennie’s vividly irascible performance.

While the signposting is a little much, the idea that Burnham does not just want a first officer who’s capable, but one who’ll have the guts to challenge her and her perspective is a good one. That approach puts her in the good company of Captain Picard, among others, and shows a humility and an openness in Michael that's commendable. Her willingness to give someone else a second chance, given what the one she received allowed her to accomplish, speaks well of the still-new Captain, and adds some poetry with Discovery’s first season in its unexpected final one.

On a meta level, this is also an interesting thematic tack for the series. Rayner is coded as conservative, battle-hardened, even sclerotic in a way that clashes with traditional Starfleet principles. The idea that he has a place on the bridge, that his viewpoint is worthwhile, and most notably, that he can be brought into the light of Starfleet’s new dawn, fits with the aspirational tone of Star Trek. It’s worth watching how the character arc, and the ideas and subtext in tow, play out from here.

The same can't be said for Book’s (David Ajala) interactions with Moll (Eve Harlow) and L'ak (Elias Toufexis). The show wants to make some trite yet strained point about bonds between individuals in the already-tortured estrangement between him and Michael. The tired pop psychology from Dr. Culber (Wilson Cruz) doesn’t help on that front. But worse yet is the acknowledged unlikely coincidence that Moll is the daughter of Book’s mentor and surrogate father, a contrived familial connection that attempts to gin up through genealogy what the show can't from character-building alone.

Except when it can. The mission may be stock, and the surrounding plot threads may be underbaked, but the goodbye between Michael and Saru is legitimately touching. From Michael nursing Saru through his harrowing transformation, to Saru counseling Michael through good times and bad in her ascent up the ranks, the pair have blossomed into genuine confidantes over the course of the last four seasons. It did not always come easily, but that's what makes their connection now, and the parting poised to strain it, such a poignant, bittersweet moment between two friends.

Who knows if it will stick. Dr. Culbert came back from the dead. Tilly’s back in the fold despite leaving for Starfleet Academy. Saru himself returned to the ship despite ostensibly leaving to become a “great elder” on Kaminar. Discovery doesn’t have a great track record of sticking to major character exits.

For now, at least, Saru gets a swan song not only worthy of what the character, and Doug Jones’ impeccable performance, has meant to the series over the past seven years, but also of what, unassumingly, became one of the series’ strongest relationships. Michael will keep flying. Saru will hopefully enjoy some wedded bliss. But as “Under the Twin Moons” reminds us, they’ve both left a mark on the other that will stay with both of them, wherever they finally end up.
