When Janey comes home for Christmas, she's pregnant and Susan wants to know who the father is. However, Janey refuses to tell her, but does tell Ben, who then lies to Susan about the father. Meanwhile, Nick starts a Christmas tree business which crowds the whole living room like a forest and then invites round Mr Bradley (Trevor Peacock), an "old person", for Christmas Day. Also, when Susan cooks the turkey with chocolate and raisins, everyone decides they are vegetarians. (thetvdb.com)
