The scene where Ashley Marin (Laura Leighton) is driving in her car with a bag of cash and gets stopped by Byron Montgomery (Chad Lowe) is a call back to a famous scene from Albert Hitchcock's movie Psycho.
The scene where Troian Bellisario, as Spencer Hastings, is packing the bag in her bedroom, features the same bag Anna gave Luke in Gilmore Girls (2000) when he was chaperoning April's school field trip.
