He hosted Rocket while his ship the Mariner was stranded after an attack by sentinels. After talking about Rocket's past, King persuaded him that he should not neglect his first love, Mona Thomas, even if she was still a bluepill.
King was contacted the next day by Pequod and found Rocket in a trash can and told him that the rescuers were about to find him. During their meeting a passer-by was transformed into Agent Brown but King shot him early. King gave Rocket the address of the exit and a gun. He was last seen shooting an Agent, formerly a kid.
