Human, ergo insignificant (unless you're Bella Sue, that is). He was one of Charlie's best friends. His only importance to the story line is to keep Charlie out of the way in Twilight, and to provide a funeral for confusion with Bella's in New Moon . Unfortunately, another one of Charlie's friends was murdered in the movie version of Twilight, so that means he will lose two friends in a span of two books. Poor guy.
