Rico, still in the base hospital, reports hearing strange noises, convinced that Bugs are about to attack, leading his doctor to contemplate giving Rico a Section 8 discharge for PTSD. Meanwhile, the Roughnecks seem to be constantly at each other's throats as they map the strange tunnels out in the jungles of Tesca Nemerosa, and  It soon becomes clear that Rico was the "glue" that held the squad together.
