Attempting to aid an injured child (Eric) in the Maze, a cave-in traps Vincent and Father. Catherine, after facing Elliott Burch, who has agreed to be a witness against an extortionist, senses something is wrong and rushes to the tunnels. When her attempts to contact someone fail, she wanders the tunnels, tripping a trapdoor which sends her tumbling down to Mouse's quarters. He leads her to the others. Mouse can save Vincent and Father, but needs demolition supplies. Catherine goes back to Elliott Burch, who gives them to her, no questions asked. Mouse succeeds; Vincent and Father are freed. Father is much more understanding of Vincent and Catherine's relationship. Catherine tells Vincent she loves him and he watches her as she returns to her world.
