Yes, I picked up on that, too, but I'm not sure how many casual viewers would actually have remembered a brief conversation a week later. That I don't remember. Dory is now sans moustache. I found it odd that that was important enough to be a plot point. My own theory is that he looked too much like John Karlen. And now I can't NOT see Barney in the credits. Now that I know where he is he sticks out like a sore thumb.
