Mike tells Susan that Mark is his son. She is upset that he's never told her he had a child. He tells her he can't handle her emotions on top of his. Martin is glad he's going out with Jenny but doesn't like Rita breathing down his neck. Brian invites Gail round for Christmas dinner, for Nicky's sake, but she's arranged to go to the Roberts'. Susan goes to see Maggie and shocks her by telling her she's Mike's wife. Susan makes her see Mike had no idea who Mark was. Maggie tells her Mike only looked upon her as a breeding machine. Martin tells Rita he is not going to take advantage of Jenny. Rita respects him for talking to her. Ivy tells Brian that her whole life is ebbing away and she's going to have an awful Christmas without her family. Susan wonders why Mike married her.
