“And I want people to feel that even as the show ends, we see Booth and Brennan walking off, and they’re changed people, but you want to have that feeling that yes, they’re still going to be out there, and they’re still going to be solving cases and making the world a better place, even if you’re not going to see them anymore. They’re still joking and laughing in the car, having their differences and having those playful fights they have. You really hope that’s still going on when you don’t see it. It’s certainly bittersweet not to be able to see them again, but just to feel that they’re all in a good place and they’re going to be okay. And you as a viewer are going to be okay, too.” - Michael Peterson
