Star Trek: Discovery Finally Gave Us A Closer Look At The Franchise's Most Mysterious Villain

Warning: This article contains spoilers for the latest episode of "Star Trek: Discovery."

"Star Trek" might represent an idealistic vision of a bolder and brighter future, but the last few seasons of "Discovery" have proven that there will always be bad guys with a penchant for muddying up those ambitions in unexpected ways — even in the 32nd Century. While the Borg, Romulans, and the warlord Khan often have a stranglehold on the title of "Best 'Trek' villains," one alien species in particular has remained shrouded in mystery for decades. First mentioned in foreboding whispers in "The Next Generation" and finally seen in the flesh (well, so to speak) in "Star Trek: Deep Space Nine," the Breen have played a significant role throughout the franchise in the years since ... yet Trekkies still had to wait until now to actually see what lies underneath their distinctive helmets.

The advantage of never showing us a Breen's face, as it turns out, is that "Discovery" was able to hide one in plain sight all along.

So far, the addition of scavengers Moll (Eve Harlow) and L'ak (Elias Toufexis) has felt like a shoe waiting to drop. The close-knit pair continue to frustrate Captain Michael Burnham (Sonequa Martin-Green) and the rest of the Discovery crew (nowhere more dramatically than in last week's time-traveling bottle episode), remaining one step ahead of our heroes in their quest to recover whatever Progenitor technological treasure hides at the end of this galaxy-spanning rainbow. About midway through episode 5, titled "Mirrors," the writers unleashed their big twist. L'ak, thus far considered an unknown type of extraterrestrial, actually reveals himself as a Breen. Or, rather, an emotional Moll lets this information slip by accident during a particularly fraught moment. In the process, "Trek" finally unmasked its most enigmatic aliens.

In the span of one episode, "Discovery" officially made "Star Trek" history.

Long treated as a mystery that left everything up to our own imaginations, the Breen reveal puts a specific face to what had previously only been a name ... actually, make that two faces. While Moll and L'ak come to a tense faceoff with Burnham and Cleveland Booker (David Ajala) on board the mirror-universe version of the USS Enterprise while trapped in multidimensional space (it's a long story), the writers treat this as the perfect opportunity to delve into the scavengers' shared past. In a series of flashbacks, we find out that L'ak was part of the Breen royal family and disgraced by his powerful Primarch uncle. Hoping to earn his way back to his people's good graces, all his plans are upended by a torrid romance with then-courier Moll. With their backs against the wall and nowhere else to turn, the lovers choose their own path altogether and, along the way, L'ak reveals his most private aspect of himself: his Breen face.

Of course, the episode adds another twist and introduces the concept of the Breen having two faces — a solid, corporeal form they can present to others if they so choose, and a more translucent one. (Really, it can only be described as squishier.) In fact, this creepy and altogether unique visage symbolizes a much more meaningful difference, as we learn when L'ak's uncle calls his chosen face an "insult to your heritage." Apparently, most Breen have moved beyond this "weak" form and consider this some sort of societal faux pas. In just a few minutes, we discover more about Breen culture than we've ever known before.
