Secrets That I Never Want to Know - S8-E1
Character mistake: When Gabby and Bree go to move Gabby's stepfather's car, they realise his car is a stick shift and Gabby says that she has driven a stick shift only once in high school. This is incorrect, as in season 7 episode 8, Gabby has to drive Hector's car home, which was also a stick.
Chosen answer: Poker. They have been playing that this whole time, once a week with everyone who was invited that lived on the Lane.
