I keep expecting that they'll have Pam end up hooking up with someone from school.
I suspect its hard for the writers to figure out what to do with the whole Jim/Pam thing, knowing that once they get married, it may well mess up the chemistry of the show. I don't think it has to though, as long as they avoid having too many episodes that focus on Jim and Pam and not enough on the other characters. I think the characters of Dwight, Stanley, Andy, Creed, Kevin and Angela are brilliant. Having Dwight fill the "Jim" role of tormenting Andy with the Cornell stuff was great.
