Despite the grand sci-fi concepts and dazzling effects that Star Trek is celebrated for, the series’ most compelling episodes often boil down to simple interactions between two unfamiliar characters. This includes Captain Picard figuring out how to converse with a Tamarian leader in “Darmok,” Kira Nerys facing off with a Cardassian war criminal in “Duet,” the turbulent initial encounter between Michael Burnham and Cleveland Booker in “That Hope Is You, Part 1,” and the iconic showdown between Captain Kirk and the Gorn in “Arena.”

There’s a particular charm in distilling the expansive Star Trek universe to just two characters, creating a dynamic and unpredictable environment that’s sometimes lost within the confines of a starship bridge. Strange New Worlds contributes a brilliant addition to this narrative approach with “Terrarium,” which is later unveiled as a precursor to “Arena.” However, the episode stands strong on its own merits, making the long-awaited Erica Ortegas-centered episode a rewarding experience.

The setup is straightforward: As the Enterprise navigates a region of space known for bizarre occurrences, Ortegas embarks on a solo reconnaissance mission into a gravitational anomaly. Unfortunately, she finds herself pulled into a wormhole and crash-lands on a barren moon, isolated from any communication with her ship. Initially, she channels Tom Hanks in Castaway, attempting to survive on her own. Her spirits lift when she discovers another stranded survivor’s campsite, only to realize her fellow castaway is a Gorn.

After it seemed Strange New Worlds had concluded its Gorn storyline, their return in this episode is a thrilling surprise. The two-part “Hegemony” had hinted at the Gorn’s complexity beyond mere savagery, making their re-emergence in “Terrarium” a deeper, more personal exploration. Despite their brutal reputation, it turns out that individually, Gorn can be cooperative and selfless.

This narrative works exceptionally well for Ortegas. Unlike La’An, whose interactions with a Gorn might seem forced, or Uhura, whose diplomatic skills might make communication too predictable, Ortegas’ unpredictable nature and previous violent encounter with the Gorn in “Hegemony, Part II” provide her with a unique blend of fear, hatred, and adventurous spirit.

Before this episode, Ortegas might have been dismissed as a character with clichéd, plucky confidence. However, Melissa Navia’s outstanding performance brings depth and intentionality to Ortegas’ traits. She comes across as a spirited high school athlete—less scholarly or emotionally intuitive than her peers, yet her determination, creativity, and positivity are vital Starfleet qualities. She motivates herself to overcome challenges and find hope, epitomized when she exuberantly crafts a water condenser.

The character development intensifies when Ortegas collaborates with her unexpected Gorn ally, whom I’ll call Gornina (as she’s simply credited as “Gorn”). If Ortegas is akin to a jock, Gornina is the artistic, solitary type they improbably befriend. Although their developing friendship follows familiar tropes of the sci-fi survival genre, screenwriter Alan B. McElroy infuses this enemies-to-allies storyline with distinctive flair.

Their alliance begins when Ortegas discovers Gornina is also a pilot, reminding us that the Gorn are a sophisticated spacefaring race, not just primitive creatures. When Ortegas creates a basic “yes/no” translator, she realizes Gornina understands everything she says. This moment, much like the one in “Darmok,” underscores the critical nuances of communication. Ortegas’ initial misstep in suggesting the Gorn learned English to “study their prey” is corrected when she rephrases it to “you want to understand your enemy,” which Gornina affirms.

The episode not only humanizes Gornina and her species through scenes where she and Ortegas share games from their respective cultures, but also reveals Gornina’s resigned acceptance of her fate due to a leg injury, believing her people would kill her rather than rescue her. It’s Ortegas’ resilience that inspires hope for something greater, mirrored by Uhura’s persistence on the Enterprise to prioritize their rescue.

While the episode excels in its portrayal of female characters, it also introduces a tragic element when La’An, mistaking Gornina for a threat, kills her after tracking Ortegas’ distress signal. This twist adds depth, avoiding a simplistic resolution and leaving Ortegas conflicted between her friendships with La’An and Gornina.

Though tying this narrative back to The Original Series through the Metrons’ experiment might seem forced, the episode’s focus on character development, particularly through Ortegas’ confrontation with the orchestrators of her ordeal, stands out. Despite a few narrative missteps, “Terrarium” remains a highlight of the season, demonstrating the power of a well-executed, simple story.

As “Terrarium” reflects some of the finest moments in Star Trek history, it also establishes a solid foundation for the unique character dynamics present in this era of Trek. This episode could well serve as a model for future narratives, balancing homage with originality as the season approaches its conclusion.

Stray Observations

• • The episode carefully explains that Ortegas’ shuttle was minimally equipped and her emergency supplies were lost in the crash, showcasing thoughtful attention to detail.
• • Ortegas’ habit of bringing paper airplanes as a talisman adds a charming retro touch to her character.
• • The consequences of La’An killing Gornina inadvertently inspire the Metrons’ later decision to force Kirk and a Gorn into combat in “Arena.”
• • The visual of Pike and Una navigating the ship through a wormhole, with Spock in the captain’s chair, is striking, although risking the entire Enterprise for one crew member is debatably reckless.
• • Ortegas’ use of a Starfleet-branded “fire cube” for cooking is a neat detail.
• • A marathon of Trek survival episodes would be a delightful way to spend an afternoon, including episodes like “Shuttlepod One” from Enterprise, “Day Of Honor” from Voyager, and “Change Of Heart” from Deep Space Nine.
