- Emily Prentiss: Sheriff, have you ever heard the saying: "does a tree falling in an empty forest make a sound?"?
- Dr. Spencer Reid: [Emily walks away, the Sheriff looks confused] It's a metaphysical riddle about unperceived existence. The answer's largely dependent on whether you subscribe to substance or bundle theory. In this case, I believe Agent Prentiss is saying that, yes, the tree does make a sound
- Sheriff Wesley Hayes: [the team is preparing to leave] Is this, eh, a normal case for you, folks?
- David Rossi: None of them are normal
- Sheriff Wesley Hayes: Well, Dr. Reid I can say it was a pleasure talking to you. I am gonna give that tree in the forest thing some more thought
- Dr. Spencer Reid: Don't give it too much thoughts though. It's basically an infallible conjecture
- Sheriff Wesley Hayes: [more confused] Copy that! Well, thanks again
- Sheriff Wesley Hayes: [cadaver dog keeps on barking] The dog looks like it's confused
- David Rossi: The dog is not confused, it's overwhelmed
- Dr. Spencer Reid: Ancient Egyptians believed the souls of the deceased would return from the afterlife to re-inhabit their original bodies, so the human form was kept intact and recognizable
- David Rossi: Did anything unusual happen in the area back then?
- Penelope Garcia: I am a firm believer that unusual lies in the brain of the beholder
- [a message pops up]
- Penelope Garcia: Having said that, the majority of brains would say this qualifies
