Thank you so much! It's funny, I never quite thought of Don and Charlie turning the "one part exuberance, two parts obsession" on each other until I typed it, and then I was like, agh, I should have thought of that aaages ago! (The rest of the fandom presumably already did, while I wasn't paying attention.) But having finally thought of it, I'm kind of unhealthy about it myself now. *g*
