Trivia

 * Ben Kelly appears in every season of the series except season 8.
 * Ben Kelly is among the only recurring characters to appear in the entire series and survive.
 * Originally Ben's role was minimal and only service as a doctor when needed, but over time his role increased, even if he wasn't in too many episodes. Ben learning about the supernatural world and Adam being the slayer was an idea throw around and never intended to see the light of day, but it was during season 5 that they finally decided to let Ben know.
 * Ben was originally intended to be made into a regular, but Matthew Fox declined due to other projects, which led to him appearing on a recurring basis as needed and due to his availability.
