Hodgins: Hey, how are you, Zack?
Zack: Quite severely injured.
Booth: There's got to be other stuff going on here, right?
Booth: Transference, uh paranoia. Come on! I mean, when I offer her a piece of pie, you say it has deeper meaning!
Brennan: I don't like pie, Booth.
Booth: Apple pie. She doesn't like baked pie.
Brennan: I don't like my fruit cooked.
Sweets: Okay, changing the subject is a way to avoid your feelings.
Booth: My feelings? Okay, now you're attacking my feelings?
Booth: Next time I die, I promise that I will tell you.
Brennan: I'll look forward to that.
Angela: I would like to welcome all of Dr. Brennan's grad students to Limbo.
Bones: It's modular skeletal storage. I don't like the moniker "Limbo."
Angela: Over 10,000 lost souls remain here, sweetie. Unidentified. Waiting. It's a good name; let's just go with it.
Brennan: It's Zack. He's the killer, Booth. It's Zack.
Brennan: All of your assumptions are built upon a first principle, Zack. To wit, the historical human experience as a whole is more important than a single person's life.
Brennan: Yet you risked it all so you wouldn't hurt Hodgins.
Brennan: I knew I shouldn't have gone to that funeral. It was a complete waste of time just like I said.
Booth: Wait a second, you thought that my funeral was a waste of time?
Cam: I thought it was a lovely service Booth.
Booth: Thank you! You know, I expected to see more people though.
Hodgins: I always imagined a lot of ex-girlfriends crying.
Booth: Yeah, me too.
Angela: You guys are pathetic.
Brennan: (to Booth) Just know I won't be attending your next funeral.
Booth: Bones, I'm telling you, you were supposed to know that I wasn't really dead, I swear! That's why I thought you weren't crying!
(about the woman who shot Booth)
Brennan: That woman was aiming at me. I would have happily taken that bullet.
Brennan: (to Booth) Just so you know I find your lack of puritan modesty very refreshing.
Cam: A toothless cannibal just can't cut it in today's competitive serial killer climate.
Hodgins: Since when did I become the assistant?
Zach: Since I became the uncontested King of the Lab.
Angela: (to Brennan) Look, I know how you see things, and I respect that. But, I need to ask you a favor. I have to go to the funeral. I'm not going to be able to get through this alone. I've been crying for like, days. I really need your shoulder here. I need my best friend.
The clocks in Booth's bathroom are all set to different times.
While Sweets is giving his TV interview, the victim from "Death in the Saddle
" is shown. However, that episode was not part of the Gormagon killings.
Earlier episodes stated Gormogon only uses widow's sons as apprentices; however, both of Zack's parents are alive.
Brennan says 180 centimeters is about 5'8". However, 180 is just shy of 5'11".
