In a briefing aboard Scirocco, Sutton shares intel from MCRN Donnager's Lt. K. Lopez's helmet cam footage revealing the remains of the Protogen scientists at Phoebe station. The bodies are burned then frozen. The data has been removed. Sutton emphasizes to Bobbie Draper that they don't have proof of the meaning or of the culprits despite what she has heard. He had lost friends on Donnager just as she had. Their mission is to deploy a party and investigate. Along the way, the UNN Nathan Hale appears to be very persistent with the objective of arriving in advance of the MCRN Scirocco, which Sutton interprets as attempting to cover up whatever is there. Rather than allow that, Sutton fires missiles at the station obliterating it along with the entire Phoebe moon. Sutton must repeatedly inform Draper that their overarching objective is to avoid war. He still hasn't convinced her since she believes Mars needs to let it happen and get it over with.
Whilst onboard the Scirocco over Ganymede, communications with the ship's Marines on the planet's surface were jammed causing confusion thus leading both MCRN and UNN forces to each believe that the other had engaged them. Lt. Sutton was determined to get communications back online. However, combat erupted between the two fleets causing damage to the Scirocco and several solar relays caught in the crossfire. Although the ship survived, he was killed on Scirocco with 11 others during the Ganymede incident.
- In the original book, Caliban's War, this character didn't exist. Gunnery Sergeant Roberta Draper reported to Lieutenant Givens, an officer on the ground posted at Ganymede station, outpost four.
