Bill is killed in the bathroom with the stolen drill. The next morning, Craig and Bryan see John walking by the dorm and try to warn him away. The group plays pool that evening, but they are interrupted after Patty sees John peering in at them through a window. Deciding to take matters into their own hands, the group decides to search for John around the building but is unsuccessful in finding him. The group prepares dinner when Craig notices some of the food is missing and sees John fleeing. While the group searches again for him, the killer smashes their dinner table with the spiked bat.
