He bonds with 12-year-old Sanosi, who is at the camp with his older sister Mariam. Dylan's compassion for Sanosi takes a turn when he finds Dylan's wallet and considers keeping it. However, that night Mariam is attacked by the traffickers and Dylan stays at the camp with them overnight to make sure they're safe.
