Who is Scott Hahn from Rome Sweet Home: Our Journey to Catholicism and what is their importance?

Scott is one of the book's two main characters. Scott is born to a liberal Presbyterian family who are not terribly interested in their Christian faith. He grows up as a standard American teenager does, trying drugs, slacking off at school from time to time. Sometimes he slips into worse things, like juvenile delinquency. Eventually a friend reaches out to him and encourages him to convert to Christianity.
