Answer:
In a prayer for Owen meaney he dies while in an airport bathroom in Arizona while taking john back to the airport. as told previously in the book Owen knew how he was to die and when he was to die, although Owen had it a little backwards because he believed he was to die in Vietnam in the arms of a nun but only half of that was correct because he was still in Arizona with the duty of delivering the casulities bodies from Vietnam home to their families. Back to his death though, the well practiced "shot" that Owen and John spent countless vacations working on in the gym at Gravesend Acadamy came in handy when they were at the airport and Owen offered to take a group of Vietnemese reffugee boys to use the restroom and then Owen's duranged friend from his post (not the one carrying the machete) comes storming in the restroom with a hand gernade screaming I will kill (what ever the ruller of Vietnam was at the time) and he said but first i will kill the enemy children and he threw the gernade and john told the children to hide under the sinks and he and Owen did the well practiced shot and threw the gernade out the window but Owen unfortunately did not live threw this shot and died.
