Together the group begins the hike to the falls, Trevor using a series of ropes he has brought along to facilitate the movement of Petey’s chair up the steeper inclines. In one frightening incident, Petey’s wheelchair tips backward, and Shawna struggles to balance Petey and the chair to keep them from falling over completely. Trevor shifts the chair forward, and Petey and the chair tip over onto him. The two teenagers struggle to protect Petey and prevent him from being dumped out of his chair. Instead of being terrified, Petey laughs with delight during the mayhem, and they eventually skid to a stop. When they reach the falls, Petey asks how the falls came to be. Trevor struggles to explain, but Petey is not satisfied, fascinated with the complex beauty of the scene before him. As they travel back to the nursing home in the van, Trevor notices a distinct smell and asks Petey if he needs changing. Petey denies that he does, and Trevor considers that he might be embarrassed to be changed in front of Shawna. Trevor asks Boyd to pull over for a moment, and Trevor asks if Shawna will take Calvin for a short walk. With Petey’s privacy assured, Boyd helps Trevor to change Petey, who is grateful for Trevor’s forethought.
