A newly free former corporate SecUnit practices passing as human while protecting the colony mission and learning self-direction.
Three broke from Barish-Estranza during the alien-contamination crisis after Murderbot 2.0 gave it the tools to disable its governor module. It refused corporate return, carried the contaminated Murderbot to safety, and began exploring freedom aboard ART, aided by Murderbot's media archive and Preservation's offer of sanctuary.
Three now accompanies Karime to a politically important meeting with a colonist faction, acting as security while pretending to be human. Murderbot monitors the assignment remotely, intending to coach Three through the social strain and shield it from ART's capacity to make that strain worse. Its absence leaves Murderbot without the backup it briefly hopes has arrived during the agricultural-bot attack.
A human-derived SecUnit of otherwise unspecified features, no longer in corporate armor, wearing clean dark-blue university crew clothing suitable for passing as human.
Three is a novice free agent and field protector whose choices test whether a SecUnit can build a life beyond corporate ownership.
