Portraits revealed through your current reading position.
An earnest Preservation biologist keeps calm under an infected bot's reach and instinctively helps Murderbot preserve its human disguise.
Ratthi has survived GrayCris's sabotage, alien predators, corporate violence, and the takeover of ART, consistently treating Murderbot as a trusted friend rather than equipment. He helped repair Murderbot after the lost-colony crisis and remains part of the joint Preservation-university effort.
While restoring a feed router with Iris and Tarik, Ratthi is trapped in a maintenance recess by an infected agricultural bot's growth-stimulator limb. He gives Murderbot a technically precise correction and insists the trapped humans can wait rather than pushing their rescuer into reckless speed. After the bot is destroyed, he runs to Murderbot, follows its covert instruction to pretend to help it stand, and channels genuine alarm into a convincing performance for Barish-Estranza.
An adult male planetary biologist of otherwise unspecified features and build, wearing a practical environmental suit during the colony router mission.
Ratthi is a Preservation scientist and emotional ally whose humane instincts repeatedly support Murderbot in both danger and recovery.
