As Susan and Carlos bond over their feelings of guilt at the murder of Gabrielle's stepfather, Mike begins to think that the two are having an affair, and Bree suspects that her detective boyfriend, Chuck, may secretly be investigating her. As her marriage continues to crumble, the tables are turned on Lynette when her usually relationship-challenged sister Lydia (guest star Sarah Paulson) comes to town and announces she's engaged. Meanwhile, after asking Renee to help his daughter, Jenny, go shopping for her first bra, Lee fears that the child is starting to bond more with Renee and becoming more distant from him.
