I totally think that is what is going to happen as well. When the fat guy left and then the criminal guy left I was thinking to myself, okay so everyone but Andy and Karen are going to leave...unless Jim and Karen breakup and then she leaves because of that. I think adding only two characters will not be bad, as it will not be as hard to remember, becuase all the other older characters are so good we do want to make sure we have time for them!!!
