Booth: Hey, so we figured we’d call and, uh, wish you a little Yuletide cheer.
Parker: Merry Christmas, Bones!
Brennan: Thanks, Parker!
Booth: Hey, listen, Bones, uh, I got a little something for ya.
Brennan: Oh, I got you something too. We can, uh, exchange gifts in a couple days.
Booth: Go to the window and open up the blinds, now.
Brennan: What?
[Brennan goes to the window and opens the blinds. She sees Booth & Parker, standing by Booth’s car, with a Christmas Tree – all lit up. They wave at her and she waves back.]
Brennan: (to her family) Hey! Everybody, it looks like we got our tree, after all.
Parker: Merry Christmas!
Brennan: I love my gift, Booth.
Booth: Merry Christmas, Bones.
