- “Damn UNSC pig...go back to Earth. You don't belong here.”— A dying Kincaide's last words to Lt. Keyes
In 2535, he was captured by UNSC forces there whilst attempting to make a weapons trade with undercover ONI agent, Captain Corinthia Hansen. When a crowd of rioters distracted Lieutenant Jacob Keyes, Major Akio Watanabe, and Hansen, Kincaide and a group of his Insurrectionists cornered the trio on a rooftop. After a while, with both sides shooting only warning shots, Kincaide and three rioters finally came out to attack them. Watanabe shot two men, but Kincaide thrust the final rioter into Watanabe, shooting them multiple times with a modified Plasma Rifle, fatally wounding the ONI officer.
After shooting Watanabe, Lieutenant Keyes then attacked him, shooting him in the shoulder, chest, and stomach. They then wrestled for the Plasma Rifle, Keyes eventually winning and then shooting off Kincaide's leg and head.
Kincaide was described as a "mid-level sort of man," and was also quite ruthless, using a man as a shield against Watanabe, and shooting both of them. He was also very determined, as before was killed, Kincaide had raised a pistol on Keyes, trying to kill him even though he had been shot several times.
