The smooth GrayCris representative sent to the ransom meeting, who draws a hidden gun and is overpowered by Murderbot.
Serrat is the GrayCris representative dispatched to the ransom exchange Pin-Lee arranges on TranRollinHyfa. Calm, confident, and faintly friendly, he arrives to inspect the funds authorization, carrying—by Murderbot's read of the scan—a device to falsify his weapons scan and a secured comm. When Gurathin escorts him to the room and Pin-Lee produces only a forged list of assets rather than a real transfer, Serrat recognizes the bluff, pulls a palm-sized energy weapon, and signals an abort and his backup.
Murderbot storms in, fries his gun, and pins him to the wall; Gurathin and Pin-Lee strip away his comm. Sneering, Serrat dismisses Preservation as naive backwater surveyors and Murderbot as a controlled tool, revealing GrayCris's fury that they exposed its 'essential asset operation' at Milu. Murderbot chokes him unconscious rather than killing him, dumping him on the couch as Mensah's implant finally pings.
A tall pale human with long light-colored hair, wearing local business attire—a dark knee-length long-sleeved jacket over wide pants; calm and confident until overpowered.
GrayCris's on-site negotiator and antagonist; the trap-springer whose capture accelerates the rescue.
