What does Taylor do to help Vernon celebrate his sixteenth birthday in the novel, Vernon God Little?

Taylor surprises Vernon by flying down to Acapulco for his 16th birthday, leading him to a room in one of the finer hotels, where she seduces him, gets him to admit he has killed for her and loved it, and gives him up to Lally's camera crew, to be turned over to U.S. marshals and flown back to Houston.
