This episode does not have any notes. Add some now!

Gideon: I like this house. Designer magazines conspicuously placed, expensive modern furniture, plasma TV. Behind the curtains, water damage. Allison spent money on the things her friends could see and neglected those they couldn't. The Crawfords lived beyond their means. (edit) Morgan: Suspect's cell is going straight to voice mail.
Dr. Rachel Howard: Karl's a good man.
Morgan: That's what everybody says until they find a body in the basement.
(Gideon turns the door knob)
Gideon: It's locked.
Dr. Rachel Howard: I'll get security.
Morgan: No. We don't have time for that.
(Morgan kicks down the door)
Dr. Rachel Howard: Someone will have to pay for that.
Morgan: Karl Arnold will. (edit) Gideon: (discussing the killer) Tells the mother, 'If you scream, I'll kill your children.' Tells the children, 'If you cry, I'll kill Mommy.' (edit) (discussing Hotch's newborn baby)
JJ: He's so gorgeous.
Haley: Thank you.
Reid: If you find baldness and wrinkles attractive. (edit) Gideon: When you have eliminated the impossible, whatever remains, however improbable, must be the truth. (edit)

Reid interviews the unsub by himself for the first time in this episode. (edit) This is one of the few times Morgan is seen wearing a suit and a tie. (edit)

Gideon: When you have eliminated the impossible…

This expression of Occam's Razor, a logic principle that states the simplest explanation is usually the correct one, and is usually attributed to Sherlock Holmes. (edit)
