Answer the following question: The answer to the question: What are the full names of the people that Carl tracks down for saving his life? is inside the article: In Santa Monica, California, a pair of Mormon missionaries—by-the-book Elder Farrell, and his soon-to-leave companion, Elder Lozano (Ignacio Serricchio)—proselytize until they are caught between a gang drive-by shooting targeting nearby thugs. The shootout kills one thug and wounds another, Carl, whom Elder Lozano saves. After being released from the hospital, Carl tracks down the two missionaries, thanking Lozano for saving his life, who gives Carl a Book of Mormon.  Later, the missionaries notice an unconscious street preacher lying behind a Dumpster. Despite Farrell's hesitation, the missionaries bring the man—later identified as Louis (Jo-sei Ikeda)—to rest in their apartment. Meanwhile, Carl, who has been reading the Bible and Book of Mormon, is eager to be baptized and begins taking lessons from the missionaries. While they do so, the missionaries ask their next-door neighbor, Holly, to check on the homeless preacher in their home. Upon their return, they have dinner with Holly and Louis and continue to do so for a few days.  In this time, the missionaries learn that Louis once was a preacher who lost his congregation due to alcoholism and that Holly—a struggling actress—acted in a few adult movies, her parents back home discovering and cutting off contact with her as a result. Elder Farrell promises that God will never stop loving her regardless of her mistakes. At a local ward luau, another missionary interviews Carl for baptism, teaching him the story of Ammon, a missionary who teaches a group of people  to give up their weapons and bury them deep in the ground, vowing never to use them again. The night before his baptism, Carl buries his weapons in the yard and Elder Lozano baptizes him the following day., can you guess it ?
Answer:
Elder Farrell
