This is the episode where Billy turns into a new man and Risa, whose man Ally had sex with, sues Ally. In the scene where Ally and Joel have just had sex again in Ally's office and Renee enters the camera sweeps from Ally to Renee and back several times. If you pay attention you notice that first Ally's hair is on a ponytail, after a view of Renee it's open on the shoulders and then on a ponytail again. This goes on several times. It's a little thing but a big thing!
