Louise's mother, Eileen, arrives at the flat and announces that she is moving in. She has left her (younger) boyfriend and is gagging for it. She goes to a club with Karen and Louise where she embarrasses them by simulating Lesbian moves with her daughter, in order to attract male attention. Donna's efforts to impress Sam's friends are equally disastrous and he eventually tells her to choose between him or Karl.
