Bones Season 4 Episode 20

Angela: That's a tire tread.
Wendell: She was run over by a car.
Cam: Seems like our victim was flattened before she was flattened.

Bones: Love is a chemical process which causes delusion. An intellectually rigorous person would never get married!
Booth: Never say never.
Bones: That's a paradox, makes no sense.
Dr. Marcus Scheer: Am I still needed here? Because if you two are having relationship issues, I can ...
Bones: We're not a couple.
Booth: No, we just work together. That's all.

Bones: You know, intellectually, I know that jealousy is absurd. But I see that it's real for people. I even experience it myself.
Booth: So uh, who you jealous of?
Bones: Angela, Hodgins, Cam, you. Because you all want to lose yourself in another person. You believe that love is transcendent and eternal. I want to believe that too.
Booth: Hey, you will. I promise. Someday, you will. You will, some day. Okay?
Bones: Okay.

Booth: Look Bones, you can't go around tellin' everybody what's on your mind even though it's the truth, okay? Look, what if you and I were going out, right? And you were, y'know, taking forever to get ready and you came out in this dress and, I told you I didn't like it, what are you gonna do?
Bones: I'd reevaluate, change, or ignore you.
Booth: (sarcastically) Of course you would, Bones. Good answer.
