Joanna is desperate to lure Statham away from Jesus. Caroline is desperate to lure Mac from his girlfriend and Sheffield. Mac challenges Guy to one final bet; that he can't bed Joanna.

Martin loves Caroline. Caroline loves Mac. So does Sue White. Mac has a girlfriend. Statham loves Jesus, or is it the chaplain? Joanna loves Lyndon. And Guy loves Guy but he pretends to love Caroline.

Caroline is broody, but she's confused. Is Guy the good guy or the bad guy? Is Mac the good Mac or the bad Mac? Martin gets his exam results.

It's a testing time for everyone: Joanna and Harriet are each convinced they're pregnant, Martin sits his exams for the hundredth time, and Mac surreptitiously attends an interview for a promotion

Martin is desperate (not just generally, although that's obviously still the case). He's worried that he hasn't got anything to wear to Caroline's housewarming party.

It's Joanna's birthday - what does a man get the woman he worships for her birthday? Would it be a locket filled with his own love juice?

Joanna is worried about her age. Who wouldn't be at her age? Her dangerous liaison with Alan Statham is now in danger of becoming tedious. She demands spontaneity. He agrees to give it some thought.

Caroline spends the day quashing rumours about her night at Guy's flat, while Guy unquashes them. If only she had something to hold over him, but surely he won't blurt out some dark secret... will he?

Dr Todd arrives at her new job, uncoiffed and under-deodorised, after spending the night in her car. Her first day gets no less hygienically and professionally challenging as she meets her colleagues.
