"What's actually amazing is that, after a couple of years of living with characters and writing characters and talking about characters, as we sit in the writers room and break episodes, it strikes you, every once in awhile, that you're talking about a character that's played by the same actor, who you've been talking about forever. We talk about a character dying, so you get emotional, and then you realize, "Oh, but wait, that actor is still on the show.""
