I think you're right, and as I said, I tend to get annoyed by shows that want to treat gay relationships as a joke-- as if they're saying, "sure, we play around with the idea, but obviously it can't actually HAPPEN." Well, why can't it happen? Are they trying to suggest a manly man like Dean could never be interested in another guy, or what? It's fine to answer, "No, Dean is straight," but to act like there's an insult to the actor and character in merely asking the question-- well, I don't like that.
