The warm Preservation biologist who tends Murderbot's wounds and rigs it a camera network on Preservation.
Ratthi, the open-hearted Preservation biologist Murderbot's neural tissue tags simply as 'my human friend,' is hands-on through the escape and aftermath: he digs the shrapnel from Murderbot's knee joint in the shuttle, frets over its unsealable wound, and does rescue breathing on a collapsed crew member during the Attacker's assault. On Preservation he helps rig Murderbot a private camera network across the guest suite so it can watch everything and feel secure, and gently guides it through its disorienting rebuild. He remains on the station with Pin-Lee and Gurathin for the meetings on GrayCris and the fallout.
An adult male planetary biologist of otherwise unspecified features, in practical clothing, warm and openly caring in manner.
Preservation biologist; Murderbot's easiest human friend and its hands-on caretaker.
