Bones Season 5 Episode 12 Quotes

Brennan: Bone graft. It looks like a repair to a screw hole.
Cam: Huh. I count three metal plates.
Brennan: Indicating multiple corrective surgeries.
Cam: Which could help us positively identify these remains.
Brennan: Mr. White told us to regard identification as a zero priority.
Cam: I'm not as good as you are at doing as I'm told.
Brennan: Thank you!

Cam: Strange question, I know, but I've gotta ask. [pulls EPT test from behind her back] Are you, by any chance, pregnant?
Brennan: No, I haven't had sexual intercourse in quite some time.
Cam: Do you want to know why I'm asking?
Brennan: You're holding a home pregnancy test. I assume it's positive and you're worried about losing the most important person in this lab.
Cam: No. Very modest. I'm asking because Michelle was here earlier this afternoon and the only other two people who you use that bathroom, beside me, are you and Angela.
Brennan: Well, Angela is currently sexually active.
Cam: Very true.
Brennan: With Wendell!
Cam: Very, very active!
Brennan: And even if they use condoms, Wendell is young! His sperm is likely to be extremely motile.
Cam: You are so cheering me up right now.
