Prentiss: All of these killings… the work of just one man?
Gideon: Most prolific serial killer ever.
Prentiss: These wind chimes are made of bone. I think it's human rib bones.
Prentiss: [watching Morgan dance between two women] Hey, Morgan, be careful. The one in the back could steal your wallet!
Morgan: That's all right; I'll be a broke, happy man!
Hotchner: [construction work in the background] What's that?
JJ: [with mouth full] One of the detectives' wives made us cookies.
Emily: Wow, homemade cookies!?
JJ: Yeah I guess that's what they mean by 'southern hospitality'.
Reid: What are you saying?
Emily: 'Southern Hospitality'.
Reid: [runs over to window and shuts it] How can anyone hear with all this work going on?!
Garcia: What was the thing that Jack the Ripper took from one of his victims, besides, well, you know, her life?
Emily: Oh, uh...
Garcia: Mmm. Tick, tock, tick, tock.
