After a volunteer fireman is found dead at an ice rink, Booth and Brennan are called to investigate. However, when information surfaces that Booth may have a conflict of interest in the case, he is removed from the investigation and becomes a suspect himself.
Booth: Bones, what are you doing in the ice?
Brennan: Well, I get nervous when you fall down and don't get up.
(while Booth fights with the hockey player)
Bones: Booth seems to be winning.
Cam: It's not Booth I'm worried about.
Alex Pina: Well, mattress really isn't uh, Chloe's style, no offense.
Agent Perotta: None taken. Favor backseats myself.
Agent Perotta: Hmm, my people were right.
Caroline and Cam: Your people?
Hodgins and Wendell: We're Booth's people.
Booth: Hey, you know what? Forget about Agent Perotta. Alright? Nothing's gonna to change between me and you.
Brennan: Well, entropy is a natural force that pulls everything apart at a subatomic level. Everything changes.
Booth: Not everything Bones. Not everything. (Booth pulls Brennan by her hand)
Brennan: (laughing) You're gonna make me fall.
Booth: I'm never gonna make you fall. I'm always here.
(after Booth fights with a guy during the hockey game)
Brennan: I do not know how I feel about this.
Sweets: It's very primal.
Cam: I like it. Just a little too much.
Cam: Well, he was a hockey player.
Brennan: So basically we're talking about gladiators.
Cam: And I love it.
Brennan: Perhaps the sight of males battling stimulates the part of your brain which has so far failed to find a suitable mate. (Hodgins enters)
Cam: (to Hodgins) And thank God you're here.
Booth: Bones I remember that guy I punched out last month during my hockey game? Pete Carlson?
Brennan: Yes, when you broke your hand.
Booth: That's him. I'm a suspect.
Despite being the prime suspect, Booth is allowed to continue to be involved in the case, which would be against any investigative protocol.
Hodgins: They should've gone at each other like a Peruvian soccer team stranded in the Andes.
Hodgins is referecing Flight 571 that crashed in the Andes in 1972. The passengers that survived the crash were forced to eat the dead passengers in order to survive. Despite Hodgins' reference, the soccer team aboard the plane was from Uruguay, not Peru.
