I forget who the owner of the blog is, but there is someone (I think it's one of the directors) that has a blog over at Blogspot.com, in which he talks about the episodes he did (he directed "Homecoming"), and talks about his experiences on the set. You could use that as a text trivia track, except I don't know the name of the guy. It's probably linked in a post over at TVSquad.com, because that's where I found the link.
