Complete story — includes the ending
Vaughn goes undercover as a priest with a dark past. He and Sydney set out to intercept a bioweapon called Ice Five, similar to the Ice Nine in Kurt Vonnegut 's novel Cat's Cradle (it causes the water in the body to crystallize instantly at room temperature). Vaughn still feels guilty over Lauren 's death; he confesses his feelings with a sympathetic enemy and he bonds with her. Nadia has questions for Jack regarding her mother, Irina Derevko.
