The Girl's Guide to Depravity - Season 1 Episode 10 The Unavailable Rule

Lizzie and Sam get a surprise visit from Sienna. Operating on the premise that men can't resist a woman who is "taken," they masquerade as Lizzie's bachelorette party and go on the prowl. Lizzie lets Marco pick her up, and takes him back to her place for one last fling. Sienna learns of Sam's interest in Richard and Jason, and insists that they attack the easier target -- Jason. They hack into his e-mail to find out where he will be, then follow him and his date, Lulu, to a movie theatre. When the film ends, Sienna creates a distraction, but Sam is unable to pry Jason away from Lulu. She and Sienna follow them to Jason's apartment building and spy through the window as they have sex. Lizzie tells Marco she's not engaged; he tells her he's married. Sienna says farewell to her friends and returns to the suburbs. Sam thinks her marriage is in trouble due to all her silly rules. She decides to get out of Jason's way and arranges to bump into Lulu to tell her what good man she's found. Sam feels pretty good about doing the right thing, but Lulu is appalled at the thought of dating a nice guy, and ditches Jason.
