Caroline tries to find a lodger for her house, but the only people who apply are a bunch of loonies and Angela. Joanna decides to attract the attention of Lyndon Jones, the Head of IT. Mac also discovers that Holly is now pregnant.

Joanna starts worrying about how old is she getting, and also about the fact that her relationship with Alan is going stale and so begins turning her attention to head of IT Department Lyndon, much to Statham's horror... To try and improve things between himself and Joanna, Alan tries to become more spontaneous (with the help of a recorder).

Mac meanwhile, discovers that his ex-girlfriend who didn't want children is now pregnant whilst Caroline sets about getting herself a lodger, though Angela is not a welcome applicant.
