in series two, leaving Tim with a flat and lodger he cannot afford to keep. Tim's sister Lucy Adams (Sally Bretton), a head hunter recently back from ten years abroad, buys the flat and becomes the new landlady and flatmate to Lee. Tim also hires a cleaner, Barbara (Miranda Hart), to clean the flat. In Gay, the series' second episode, 51-year-old Guy first appears and he soon becomes Lucy's boyfriend. Lee, now an ice-cream seller, later appears to fall for Lucy. In the last episode, Tim and Lee are convinced Guy is a gangster and has been smuggling diamonds, but it turns out that he was having a diamond engagement ring made for Lucy planning to propose on a romantic holiday. Lee leaves the airport thinking Lucy has said yes to Guy, but she returns saying that she was too young to get married and that she had split up with Guy. There was also a Christmas Special in 2007 which introduced Tim and Lucy's parents - Wendy (Deborah Grant) and Geoffrey (Geoffrey Whitehead) - for the first time. In episode 6, Lee meets a ditzy woman called Daisy at speed dating, who later appeared to fall for Tim. Although at the time it seems that she will be a one-time character, she reappears in the Christmas special as Tim's girlfriend and returns in series three. The third series sees Lee trying to pursue Lucy. Usually encouraged by Barbara, he invariably ends up making things worse for himself. We also witness Lucy questioning her sexuality, which worries Lee. Daisy also becomes more of a fixture in series three. In the last episode, Lucy is about to marry Pavlov, a mechanic, so he can stay in the country. However, she realises that she's made a mistake, and Lee gets Barbara to marry Pavlov instead; the last scene is of them driving off together for their honeymoon in India. Barbara is seen back in the flat, wanting to go off with Lee's dad, Frank, who is seen in the last episode, which was broadcast as a Christmas Special on 23 December 2009. Lucy and Lee kiss under the mistletoe. A fourth series of six episodes was filmed from late September to early November 2010. Miranda Hart did not return as Barbara, as filming of the second series of her own sitcom Miranda was also taking place. The series began airing on 6
