When a Man Walks into a Bar - S1.E21

Katy has to come home from the city. Tom drives her home, and when they get there rumors start flying about Tom and Katy once at Bert's party, which everyone wasn't going to come to. Marissa moves back to the city, Sandra also notices her feeling a little flat and has a chat to her about Tom (after she eats all of Pip's chocolate). Marissa thinks she has the worst taste in men because Tom has not responded to her.
