A fanlisting is a place for all fans of a particular show, movie, actor, actress, singer, etc. to come together and build the biggest listing of people from all around the world who are fans of that subject.

Harrison John was the original male member of the "wannbe" crowd along with Sam, Lily and Carmen. Throughout the show he went from obsessing about the head cheerleader, Brooke to falling for his best friend Sam. In the second season we learned he had leukemia and received a bone marrow transplant from uber bitch Nicole Julian.
In the series finale he was forced to choose between Brooke and Sam. The WB cancelled the show so we never found out whom he chose.
