Two and a Half Men Episode 7.02 Whipped Unto the Third Generation

It appears to Charlie that Alan's girlfriend Melissa has moved in to his house, but Alan insists that she has only been visiting and isn't living there. Charlie complains to Chelsea about Alan secretly moving Melissa in, but instead of taking Charlie’s side she takes Alan's, saying that Charlie should be supportive. Meanwhile, Melissa tells Alan that she wants to move in some of her furniture, but knowing that Charlie would never agree, Alan says they should leave everything as is. However, Melissa pressures Alan to confront Charlie, who is already prepared to let Melissa move in because of Chelsea. Ultimately, Chelsea and Melissa take over the house, and Charlie and Alan end up in a hotel. In order to get things back to normal, Charlie and Alan call on Evelyn, who intentionally spills the beans about Melissa and Charlie's history to Chelsea, who then kicks Melissa out of the house.
