Derek Morgan : Where are we?
David Rossi : Honestly? Nowhere. We just watched our two most viable suspects walk out the door.
Emily Prentiss : If Adam isn't our unsub, he has all the makings to become one someday.
Aaron 'Hotch' Hotchner : Reid?
Dr. Spencer Reid : Tell me the question that he spiked under in the polygraph.
Derek Morgan : It was a control question to set the baseline.
Dr. Spencer Reid : It was a geometric equation?
Derek Morgan : Reid, I really think he was just intimidated. He tried, he got it wrong, but he wasn't supposed to know the answer anyway.
Dr. Spencer Reid : What if he lied? What if... what if he knew the answer to the question but intentionally got it wrong?
Jennifer 'JJ' Jareau : Why would he do that?
Dr. Spencer Reid : Because he realized that he wouldn't know that answer.
Derek Morgan : You're losing me, kid.
Dr. Spencer Reid : Adam said he wasn't getting any rest. He takes midday naps because he's always exhausted. He has a history of blackouts, reclusive behavior, prolonged repeated abuse suffered at the hands of a dominant male who transferred abuse from his female spouse to his prepubescent child.
Aaron 'Hotch' Hotchner : Where are you going with this?
Dr. Spencer Reid : What if our ubsub couple isn't a couple at all?
Aaron 'Hotch' Hotchner : Dissociative identity disorder.
David Rossi : You think Adam's a multiple personality?
Emily Prentiss : Well, it fits. Recurrent physical abuse, knowledge he shouldn't have. We've seen this before.
Dr. Spencer Reid : Look at this. All right? The-the first intervention is timid. It's apprehensive, right? But then he gets knocked down... there's a moment of calm, and then his entire body language changes. I saw this exact same transformation when Adam left the station, only it wasn't rage, it was, uh... arrogance. Like... like the alter ego wanted me to know.
Aaron 'Hotch' Hotchner : Why?
Dr. Spencer Reid : I don't know. Power, control. All I know is the person that stared me down over there was not Adam. He's not assertive like that. He doesn't make eye contact.
Jennifer 'JJ' Jareau : So you think the stress of the interrogation blurred the line between Adam and his alter personality?
Dr. Spencer Reid : I think the unsub surfaced for just a moment. It-it-it knew the answer to the question, realized Adam wouldn't, and lied.
