A two-minute extension at the end of the the episode, "The Truth in the Myth" that celebrates the friendship of Angela and Brennan.
Brennan: Are you trying to confuse me?
Booth: I might be.
Brennan: What is your point?
Booth: That things are confusing, okay. Just because you can explain something, doesn't mean it's explainable.
Brennan: You mean explicable?
Booth: Sure, like us. We don't make any sense at all.
Brennan: Good night.
Booth: Bye.
Booth continues to walk down the street. His cell phone rings. He pulls the phone out of his pocket. Displayed on its screen is a picture of Brennan. The display reads, "text message, view now?" Booth presses the 'yes' button on his phone. The text message reads:
"Right now I am sitting in this cab wishing I had kissed you before I left."
Angela is sitting next to Brennan in the yellow cab, handing Brennan back her cell phone.
"Ange, I don't know what that means. I don't think you should text things unless I know what they mean. "
"Sweetie, maybe you should just come home with me and we can talk it through. Just like we do when we write the sex scenes for your books."
"Booth knows you write those scenes for me. I told him. Someday I will have to tell him that you've helped me with my text messages."
"Someday. Just not today, Sweetie." Angela raises her eyebrows and exchanges a look of confidence with Brennan.
