Carrie and Big finally seem to be getting along fine, despite the girls's pressure for her to define what kind of relationship she has established with him. Carrie doesn't know it herself, but it clearly shows as not being a regular friendship when she flirts with a jazz player. Big shows up on their date and acts jealous about Carrie, and she has to set some boundaries. Meanwhile, Miranda lowers her boundaries too when she decides to let her boyfriend pee with the bathroom door open, but changes her mind after he decides to do everything else with the door opened. Charlotte sets her boundaries on Trey, who wanted to have sex on virtually every room they stepped into, and Samantha lowers her boundaries on relationships when she decides to take on a lesbian relationship with a Brazilian artist.
