She finds the old outhouse and enters, and Mike's severed head falls on her, causing her to panic and scream.Nathaniel and the rest of the group come to her aid, then start a search for Melanie. They decided to spend the night in the camp. In the morning they go to the cabin to try to capture the mountain man who killed Mike.

The creature throws the dead body of Melanie in the boat causing chaos.Burying Melanie near the river, the group continues on to the end of the river and finds their empty, broken-down bus on a bridge.
