The next morning, Joseph suggests that he and Clark walk back to the couples car and siphon off the gas, then continue on to Josephs truck and leave the area. Summer wants to accompany them, but Joseph and Clark both say that in her delicate condition, she should remain. Joseph pulls out a revolver and teaches Summer how to use it, touching her in an intimate way. Clark is obviously furious, but he and Joseph still set off together. On the way, Joseph continually mocks Clark for his weaknesses, claiming to know everything about him. Clark is convinced that Joseph is a fanatical, religious hippie. When they arrive, Joseph tells Clark that everything he is about to go through is his own fault, because of his sins, then disappears. Clark opens the trunk of his car to find Bens rotting body, buzzing with flies. He is horrified, then realises that he has left Summer alone and rushes back.Meanwhile, Summer has found a room in one of the abandoned buildings with photographs on the wall, including her photo of Ben, with a cross scratched over his face. She turns to find that Joseph is in the room with her. She attempts to shoot him, but the gun he gave her is unloaded. Joseph subdues her and uses a razor to carve a cross into her forehead, saying that she will have the mark forever and will remember what happened there. She begs to know why he is doing this and he claims that it is Gods will. At that moment, Clark arrives and attacks Joseph, beating him to the ground. ........
