Reid: (to Dr. Bryer) The voices, they helped you right? While the other kids were outside in the playground you were inside studying, reading, learning. The voices wouldn't stop. They helped you understand things that other people couldn't realize. Then as you grew older it became almost a responsibility, right? A responsibility to use that ability, to use your knowledge. (edit) Reid: The voices, they won't stop. They've been talking to you since you were a child.
Leo: He's telling you I'm not real. He is lying to you.
Dr. Bryar: You're lying to me.
Reid: That's Leo speaking; that's not even Dr. Bryar. Why won't you let him think for himself, Leo?
Dr. Bryar: You...can you see him?
Reid: Yeah, he's right there. (edit) Reid: I know what it's like.
Dr. Bryar: Make it stop!
Reid: I know what the voices are like. (edit) Reid: Tardive dyskinesia.
Morgan: Once more for those of us who don’t have an encyclopedic memory? (edit) Reid: Could you guys do me a favor?
Morgan: Anything.
Reid: Could at least one of you look like you're going to see me again?
Hotchner: See you when you get back. (edit)

Elle was traveling to Dallas, yet she flew into an airport 637 miles away, in El Paso, and then took a train back (north and east) to Dallas. Dallas/Fort Worth has an international airport. The Amtrak trip from El Paso to Dallas takes 29 hours 30 minutes. (edit) In the train from West Texas, there is a Washington D.C. Metrorail map hanging on the wall.

Early in the episode when the BAU team is riding up in the SUV, the camera shows the vehicle from the outside, and suddenly we see there is no one in the back seat. (edit)

Reid mentions Ralph Tortorici taking a classroom full of students hostage because he thought microchips had been implanted in his body. This happened in 1994 at SUNY Albany. All of the hostages survived but one man was injured during a struggle for Tortorici's gun. Tortorici committed suicide in a correctional facility in 1999. (edit) Reid mentions mathematician John Nash as an example of someone who suffered from delusions, and Morgan says that he saw the movie. The movie about Nash is 2001's A Beautiful Mind, directed by Ron Howard and starring Russell Crowe. (edit)
