Susan finds Richard's rubber duckie hidden in Henry's shed and confronts him with it. Henry grabs the duck from her hands and tosses it in the well. Later, he suggests that they go for a walk. Susan asks whether he killed Richard, and Henry replies, "What if I did?" When she mentions getting help for him, Henry says that he'd rather be dead than be sent to one of "those" places and runs off. Having seen Henry and Susan walk off together and fearing that Henry intends to kill her, Mark breaks the window in the room where Uncle Wally (Daniel Hugh Kelly) has locked him and runs after them. Henry leads Susan to the top of the cliffs, then hides in the trees. When Susan peers over the edge of the cliff, Henry jumps out and pushes her off. Susan gets caught in some tree branches and is left hanging there. Henry picks up a large rock with the intention of tossing it on Susan, but Mark runs up and tackles Henry to the ground. As Susan makes her way up the cliff wall, Henry and Mark struggle, Henry saying repeatedly, "I'm going to kill you." Susan reaches the top just as Henry and Mark roll off the cliff. Susan is able to grab them both, one boy hanging from each of her arms. As the boys start sliding further and further down Susan's fingers, Henry reminds her that he is her son and that he loves her and asks to be given both of her arms (which would mean dropping Mark to the rocks below). Unable to lift both of the boys to safety, Susan says, "Henry, forgive me", and lets him fall so that she can help Mark. In the final scene, Mark looks out over the red rocks and, in a voiceover, says that he wonders whether Susan would make the same choice if she had it to do over again but admits that he's not about to ask.
