- Sam Novak: [He addresses Parker and Knight as they enter the Interrogation Room] Well, welcome. Please come in, have a seat
- Leon Vance: Why did he stop teaching?
- Jessica Knight: Totaled his car a few years ago, busted his head open. After that, he informed the university that he was no longer fit to teach
- Leon Vance: No arguments here
- Alden Parker: Director, you got something for me?
- Leon Vance: I asked Dr. Mallard to do a psych eval on our serial killer. Which Dr. Palmer has agreed to present.
- Alden Parker: Okay, Jimmy, what do ya got?
- Jimmy Palmer: Well, what I have is a history lesson. Uh, in 18th century France, people with two different colored eyes were seen as possessed. They were teased, they were ostracized, sometimes they were even killed.
- Alden Parker: That's a common theme throughout time.
- Jimmy Palmer: Yeah, to treat people who looked or acted differently as evil spirits.
- Leon Vance: Like the witches of Salem.
- Jimmy Palmer: We all know how they were punished.
- Leon Vance: They were hanged.
- Jimmy Palmer: Any guesses as to how they treated heterochromatics
- Alden Parker: Chopped off their heads?
- Jimmy Palmer: The belief was that in order to vanquish the demon they needed to separate the head from its soul.
- Leon Vance: So history is repeating itself. Why?
- Jimmy Palmer: We can only guess. Perhaps the killer suffered some sort of trauma at the hands of a heterochromatic person, and now is seeking revenge on anyone with two different colored eyes.
- Leon Vance: That doesn't explain why Lieutenant Harlan was targeted. Or the bomb.
- Alden Parker: We just learned that her husband has different colored eyes. Our theory is that the killer got the wrong Harlan.
- Jimmy Palmer: I don't think so. Our killer has been careful so far.
- Leon Vance: So you're thinking that there's another reason she would've been targeted?
- Jimmy Palmer: Maybe. If you look closely, there's one person waiting to be executed who is not heterochromatic.
- Alden Parker: Two brown eyes.
- Jimmy Palmer: Notice anything else about her?
- Alden Parker: She's pregnant
- Jimmy Palmer: Historically, women who were impregnated by heterochromatic men were also targeted, because the trait is hereditary. So if Lieutenant happens to be pregnant, her child would likely have it, too.
- Leon Vance: And since you can't chop off the head of an unborn child
- Alden Parker: You blow up the mom instead.
- Leon Vance: We need to get the Harlans into protective custody.
- Alden Parker: McGee and Torres are on the way to their house now.
- Chloe Marlene: Did you find Sanchez's body?
- Timothy McGee: We did.
- Jessica Knight: Plus a couple more.
- Chloe Marlene: Uh more - more what, headless bodies?
- Nick Torres: Yeah, but if it makes you feel any better, we also found their heads.
- Leon Vance: You're asking me to allow a movie star to interrogate a serial killer?
- Alden Parker: Yes.
- Leon Vance: And you think that's a good idea?
- Alden Parker: No, but it's the best bad idea we have.
