Episode Timeline

Episode 1
FreeCommerce

FreeCommerce opens with Murderbot secretly free inside a rented SecUnit body. PreservationAux accepts the unit for insurance and mission safety, then quickly learns the planet is more dangerous than the company data suggested. Murderbot saves Bharadwaj and Arada from a creature attack, lowers its mask to comfort Arada, and accidentally gives Gurathin reasons to suspect it is not acting like an ordinary SecUnit.

Episode 2
Eye Contact

Eye Contact sends Mensah into danger without Murderbot while Gurathin presses the SecUnit about its abnormal behavior and deleted memories. The episode uses literal and emotional eye contact to tighten the trust conflict: Murderbot can protect people from field threats, but it cannot easily survive being watched, questioned, or recognized.

Episode 3
Risk Assessment

Risk Assessment sends part of PreservationAux to the other research habitat after the team cannot reach the opposite-side crew. Murderbot arms the group, enters first, discovers dead researchers and destroyed SecUnits, and lies that everything is fine before being attacked by a hostile SecUnit. The episode makes risk assessment moral as well as tactical: what should Murderbot tell humans who may not survive the truth?

Episode 4
Escape Velocity Protocol

Escape Velocity Protocol follows Murderbot after a hostile SecUnit captures it, drags it through Sanctuary Moon hallucinations, and installs a combat override module. Mensah and the team rescue it, but Murderbot knows the override may force it to kill them. When the humans cannot execute it, Murderbot takes Mensah's gun and shoots itself to keep them safe.

Episode 5
Rogue War Tracker Infinite

Rogue War Tracker Infinite begins with Mensah choosing to bring Murderbot back to the habitat for repair. Leebeebee appears claiming to be a DeltFall survivor, Gurathin discovers that Murderbot had already hacked its governor module, and Mensah chooses trust because Murderbot protected the team. The episode ends with Mensah and Murderbot flying to manually activate the emergency beacon, only for it to explode.

Episode 6
Command Feed

Command Feed follows Mensah and Murderbot after the beacon explosion. Murderbot calms Mensah's panic with Sanctuary Moon, helps repair the hopper using neural fibers from its own spinal cord, and returns to find Leebeebee threatening the team. Leebeebee admits she belongs to the hostile third party, and Murderbot kills her immediately, shocking PreservationAux and complicating the team's view of its violence.

Episode 7
Complementary Species

Complementary Species reveals Gurathin's Corporation Rim past and suicidal history before Mensah, then follows PresAux as the team prepares to evacuate. Murderbot tracks Gurathin's rising temperature, alien creatures attach eggs to the hopper, and a superior SecUnit attacks. When alien eggs are destroyed, the creature kills the attacking SecUnit, but Gurathin collapses and Mensah orders a return to the habitat medical bay.

Episode 8
Foreign Object

Foreign Object brings PresAux back to the habitat, where recordings reveal superior SecUnits and a GrayCris representative leaving a rendezvous demand. During surgery on Gurathin's leg, Murderbot connects to his data port to reduce his pain, allowing Gurathin to discover Murderbot's private name and its connection to the deaths of 57 clients. Murderbot leaves after accepting it may be dangerous, then returns with a plan against GrayCris.

Episode 9
All Systems Red

All Systems Red puts Murderbot's dangerous plan into motion. It pretends to betray PresAux to GrayCris while secretly using Gurathin, a drone transponder, and the GrayCris HubSystem to launch the emergency beacon. Murderbot stalls with awkward small talk and Sanctuary Moon quotes until GrayCris prepares to torture it, Mensah intervenes, and Murderbot shields her from the beacon blast that kills the GrayCris team.

Episode 10
The Perimeter

The Perimeter follows Murderbot after its systems reboot under company control. Technicians delete its memory and install a new governor module, but PresAux fights back through negotiation, legal pressure, Gurathin's recovered data, and Sanctuary Moon file traces. The team restores Murderbot and invites it home as a free agent, yet Murderbot chooses to leave on a transport ship rather than let belonging become another perimeter around its autonomy.
