Cam: (reading out of a script) Well, there's a little thing that looks like a Japanese stool, then a 'b' with a tail, then a fat fish. Does this make sense to you?
Zack: It doesn't to you? (edit) Hodgins: Hey, how are you, Zack?
Zack: Quite severely injured. (edit) Caroline: (at the funeral) I knew Seeley Booth. He was a good man, who earned my respect and affection - and I don't like many people. (edit) Cam: I knew, the day I met Zack, he'd cause me pain. (edit) Booth: There's got to be other stuff going on here, right?
Sweets: What?
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? (edit)

There are five clocks on the wall in Booth's bathroom. They are all set at different times: 1:40, 2:10, 11:50, 10:05 and 8:35. (edit) In earlier episodes it was stated that Gormogon only takes widows' sons as apprentices, yet Zack has both of his parents - they're alive and well in Michigan. Even though Zack worked in the Jeffersonian and had special access to Gormogon's vault, Gormogon still broke his own rule by making Zack his apprentice. (edit) Goof: During Sweets' interview on TV, victims' bodies are shown - the second body shown is that of Ed Milner, who was discovered in the "Death in The Saddle" episode and who has nothing to do with the Gormogon case. (edit) The symbols Cam explains to Zack right before Brennan and Booth show up to confront him are pi (the "japanese stool"), beta (the "B with a tail"), and alpha (the "fat fish"). All are common symbols in Calculus. (edit) When Brennan and her student are talking about the skeleton from Limbo, Brennan says the femur indicates a height of approximately 180cm. When asked what that is in English, she says about 5'8". 180cm is actually just under 5'11". (edit)

David Boreanaz is seen reading a Green Lantern comic book in his bathtub. David Boreanaz voiced the character of Green Lantern in the 2008 animated video "Justice League: The New Frontier". (edit)
