The episode "Complementary Species" opens with a flashback to the night before the current events, at Port Freecommerce. The Preservation Alliance crew, including Gurathin, PresAux, Bharadwaj, Arada, Pin-Lee, and Mensah, engage in a party game mixing Truth or Dare with therapy, where they share one "sweet" and one "bitter" emotion. This scene reveals interpersonal tensions, especially Gurathin's discomfort and jealousy regarding Mensah's possible feelings for Murderbot. The game highlights the crew's close-knit but complex relationships and sets the emotional tone for the episode.

Back in the present, the team is on a hostile alien planet dealing with the aftermath of previous attacks. Murderbot, now free from its governor module, exhibits a sarcastic and defensive attitude when questioned by Ratthi about its intentions. Arada and Pin-Lee try to prevent Ratthi from confronting Murderbot, but he insists on knowing what Murderbot plans to do next. The group is stressed and uncertain, with no clear plan, reflecting the tension and mistrust among them.

Mensah calmly asks Murderbot to lower its face shield so the others can see it as she does: a being who wants to help. Murderbot agrees, signaling a moment of tentative trust and connection between it and the human crew. This interaction deepens the evolving relationship between Mensah and Murderbot, showing a shift from suspicion to understanding.

Suddenly, two giant alien insects erupt violently from the ground near the team's location. One is recognized as the same species that attacked Bharadwaj earlier in the series, while the other is larger, armored, and more menacing. The team scrambles as the insects pose an immediate threat. Murderbot quickly ushers the group to safety, demonstrating its protective instincts despite its conflicted feelings.

The insects engage in a violent confrontation, with the larger one attacking the smaller. The smaller insect uses the team's hopper vehicle as a mating site, attaching egg sacs to it. Arada, ever the biologist, is excited by this natural event despite the danger. Her fascination is cut short when an Evil SecUnit suddenly appears and destroys one of the egg sacs, escalating the threat.

Hostile One, the larger insect, kills the Evil SecUnit after it damages the egg sac, removing the immediate mechanical threat. Meanwhile, Gurathin's leg wound worsens, and he collapses from blood loss and exhaustion. The team recognizes the urgency of his condition and decides to return to their habitat's med bay for treatment, despite the high risk of encountering whoever controls the hostile SecUnit.

PresAux insists on accompanying Gurathin back to the habitat, even though Murderbot resists the idea, knowing the danger. The humans' willingness to risk their lives for one of their own, and for Murderbot, underscores their loyalty and solidarity. Mensah offers Murderbot the choice to come with them, saying, "You can come if you want." The episode ends on this uncertain note, leaving Murderbot's decision unresolved.

Throughout the episode, the tension between the crew's interpersonal dynamics, the alien threats, and the moral choices they face drives the narrative forward in a detailed, step-by-step progression of events.

At the end of Murderbot Season 1, Episode 7, "Complementary Species," the PreservationAux team faces a dire situation when Gurathin collapses from his leg wound, prompting the group to decide to return to the habitat's medbay despite the high risk. Murderbot, now more open emotionally, lowers its face shield at Mensah's request, revealing its desire to help. Just then, two giant hostile alien insects emerge, threatening the group. The team survives thanks to the intervention of the alien wildlife and their own unity, with the episode ending on a tense note as Murderbot contemplates whether to accompany the team back to the habitat or leave them to face danger alone.

Narrated scene by scene:

The episode opens with heightened tension among the PreservationAux team and Murderbot. Gurathin, visibly unwell and increasingly unstable, struggles with his leg wound. The team debates their next move, knowing that returning to the habitat's medbay is dangerous but necessary for Gurathin's survival. Murderbot, who has been sarcastic and emotionally guarded, is confronted by Mensah, who asks it to lower its face shield so the others can see it as more than just a security unit. After some hesitation, Murderbot complies, revealing a more vulnerable and willing side.

As the team prepares to move, two massive alien insects burst from the ground near their hopper. One is recognized as the same species that attacked Bharadwaj earlier in the series, while the other is larger and more heavily armored. The insects' sudden appearance causes chaos, but the team manages to hold their ground. Arada, the biologist, is fascinated by the insects' behavior, noting that the hopper has become a mating site for these "complementary species," with egg sacs attached to it. This biological event is interrupted when an Evil SecUnit arrives, escalating the threat.

During the confrontation, the hostile alien insect kills the Evil SecUnit after it destroys one of the egg sacs, which momentarily shifts the balance of power. Gurathin, weakened by his injury, collapses, and the team unanimously agrees that he must be taken back to the habitat's medbay despite the risks. Murderbot warns them of the danger but is faced with the choice of either accompanying them or leaving them to face the threat alone. Mensah offers Murderbot the choice to come along, emphasizing the team's trust and willingness to protect one another.

The episode closes with Murderbot contemplating this decision, highlighting its internal conflict between self-preservation and connection to the team. The fate of the main characters at this point is:

• Gurathin: Collapsed and in critical condition, needing medical attention at the habitat.
• Mensah and the PreservationAux team: Determined to protect Gurathin and each other, ready to face the dangers ahead.
• Murderbot: Emotionally opening up, choosing whether to join the team in their risky return or to go its own way.

This ending sets up a tense and uncertain future, emphasizing themes of trust, vulnerability, and the evolving relationships between Murderbot and the humans it protects.
