I agree with you all that it would be nice to NOT have him thrown in there just as a short romantic arc...hopefully from this paragraph:
Quote
We have spoken to Dean's people. We have not found a story yet that we want to put him in. I think if you're going to get somebody like Dean, you've got to make sure that the role is right, and that the episode is good. He is definitely someone we want on the show, and as soon as we find the right episode and the right character, we will move on it, and hopefully given his schedule, he'll be able to do it."
they agree with us...
