Bree introduces herself to new neighbor Betty Applewhite and her son Matthew. She asks Betty if she can play the organ at Rex's funeral since their organist is on vacation. Betty says to Matthew that telling the neighbors that his dad is dead is a bit morbid. Matthew just thought it would help with their cover story. At the end of the day, we see Betty Applewhite and Matthew head into their basement. She's carrying a tray of food, he's carrying a gun. Once they're gone, we see what looks to be a hand bound by a leather restraint reach out to grab a drink off the tray. Hmmm.
