Right after Girl in the Gator
" Booth...it seems you've been hiding things from me."
"What? Hiding things from you? What have I been hiding from you?"
"Sully took me out for a piece of pie last night, because, you know, the case was over so it was permissible with the FBI…he's very attractive."
Booth rolled his eyes. "You don't even like pie. Why would you want to go have a piece of pie if you don't like it?"
Brennan smiled. "Well, as I said, he's attractive and he seems quite intelligent. Anyway, we went to the diner and I told Sully I don't really like apple or cherry pie because I don't like cooked fruit."
"My point exactly", interrupted Booth. "Why go at all?"
"Sully introduced me to a kind of pie I'd never had before. He ordered a slice of pecan pie for me, and he asked the waitress to warm it up slightly, and to bring a small dish of vanilla ice cream on the side. You never told me about pecan pie, Booth. It was different than fruit pie, and I really enjoyed it tremendously."
Booth was not impressed. "So was it the pie you liked or was it Sully? It seems like he was maybe hitting on you a little bit, getting you that fancy piece of pie."
"Food can be quite useful in seduction, Booth. Anthropologically speaking, cooking or buying a meal for someone implies a social contract."
"Right." Booth was becoming uncomfortable with the direction of the conversation. "Well, sorry I never told you about pecan pie a la mode. I guess I have been hiding things from you."
"That's okay. Sully and I are going out to his favorite restaurant tonight...Thai food. Oh...gotta get going. See you later."
Booth sighed. "Thai food and pecan pie. What a combination."
