The Carrie Diariesis really getting juicy, as Walt (Brenden Dooling) and Mouse (Ellen Wong) get more in tune with their sexuality. Well, Mouse anyway. It seems that since she got back with Seth, she's gotten nervous about her abilities. What is she supposed to touch and how? Where does she put her... In Season 1, Episode 4 "Dangerous Territory," Mouse turns to Walt for help with the big questions about the big "It."
