Zelia is a Mexican-American girl and devout Catholic whom Cappy meets while she is on a summer mission trip to the reservation. Zelia is extremely beautiful and she and Cappy fall in love after Cappy courts her by attending the church’s youth group. Zelia and Cappy have sex in the graveyard and in the church basement before Zelia returns to Montana. She helps open Cappy up to religion, teaching him about the rapture and encouraging him to go to confession. Zelia corresponds with Cappy via letters until her parents find out and send Cappy a threatening letter, instructing him to stop speaking to their daughter. It is this letter that compels Cappy, Angus, Zack, and Joe to drive to Montana, where they get in a car accident that kills Cappy.
