Larry is part of the First or Second Cohort, as he is one of the people defending the fort during Camp Jupiter's war game. The Fifth Cohort managed to break through his defenses and win the game. During the Senate meeting to discuss the quest to Alaska, he seconds Senator Hank's objection to all Fifth campers going on the Alaska quest, claiming it would be suicide even with demigods from a good cohort. By saying this he is indirectly saying that the fifth cohort as everyone says is the "loser cohort". Frank Zhang retorts that Larry's cohort had their 'podex' whipped by the Fifth at the Roman War Games the night before.
