Dr. Spencer Reid: Let's pretend you're telling the truth. That means I guessed it, right? The secret, the one I don't want to admit to? It's my child?
Cat Adams: Is that your guess? You only get one, remember?
Dr. Spencer Reid: No. It's too easy.
Cat Adams: Believe me, getting pregnant with your baby was not easy.
Dr. Spencer Reid: You misunderstand. It's too easy emotionally. Because I can take your child from you. The child I had absolutely no role in creating, but a child that I would care for better than you.
Cat Adams: That's rude.
Dr. Spencer Reid: It's true. You can't be a mother, Cat. I'm not trying to insult you. It's your psychological makeup. You literally do not have the emotional skills to care for another human being. You'd lose interest in your own baby the way a six year old loses interest in a pet hamster.
