Baines decides that if Diana and Tom are seen to be mentally incompetent it will give him power of attorney over them and end all his troubles, particularly as the home is in financial difficulties. So he refers them to psychiatrist Dr.Darrow, for whom they act out a well-rehearsed pantomine of odd behaviour, leading the doctor to conclude that they are not mad, just a touch eccentric, with unexpected help coming from Sarah.

Tom 's belief that one should always tell the truth offends Jane, who has made herself look glamorous to appeal to Baines and Tom says she looks hideous. He also upsets Marion by telling her what he thinks of her, leading to a big row.

Sarah introduces her boy-friend Sam, who is looking for investors for his proposed beauty salon franchise, but Diana and Tom suspect he is a con-man and Tom - to make his peace with Marion - 'persuades' Sam to let his daughter run her own beauty salon for free.

Diana falls and breaks her hip whilst throwing a brick at the home's incompetent South American gardener. She is taken to hospital where she rows with the Welsh doctor over a hip replacement operation and Sarah, about to marry Sam, comes to visit. Sarah knows that Diana dislikes Sam and wonders if she will try to stop the wedding..or even attend.

In the end Diana turns up for her niece's big day, using a Zimmer frame.

Marion, meanwhile, is not making a success of the beauty shop and Tom suggests Sam take back the franchise.

Diana collapses and is rushed to hospital where Baines tries, unsuccessfully to cop off with the lady doctor.

Diana, wrongly, gets it into her head that she is dying of cancer and asks Tom to get her some sleeping pills so that she can end it all quickly. For Tom, however, there are limits as to what he will do for his best friend.

The residents are getting wet waiting for a bus but when it arrives the driver claims that they cannot get on for free for another four minutes as they are too early, so Diana hauls him off the bus and Tom hi-jacks it on behalf of the residents.

Later this will come in handy when a very pregnant Sarah arrives, seeking Diana's reluctant help to deliver her baby. Ultimately a girl arrives, unsurprisingly, Sarah calls her Diana.

Diana is horrified to find that she is unaccountably in the red and goes up to London to cause a fuss, only to discover that all her investments have gone into receivership.

Back in Bayview, Tom's room is suffering from severe rising damp so Tom comes up with a solution that will sort things out for them both. They will live together in one large room. Diana accepts this but draws the line at being carried over the threshold.

Living together is not the bed of roses that Tom and Diana were expecting. He criticizes her sloppiness and her funny little ways, such as feeding acorns to squirrels with a sling-shot. She decides to move out and goes to stay with Sarah to be a nanny to baby Diana but this is not her forte.

Tom misses her, especially when Geoffrey decides to move in with him again.

Geoffrey is getting on Tom's nerves with his obsession with shelves, which he keeps putting up all over the unit and it's a blessing when he gets a call from Marion, asking him to get back with her.

Tom is not the only resident missing Diana as she is seen as a source of advice, but Diana herself, a thoroughly incompetent nanny, is missing Bayview and, after ruining a fashion show goes 'home' to Tom.

Whilst planning his pre-nuptial agreement with an eager Jane, Baines is told that he is not a proper priest and that any attempts he makes to get money from his ordination will lead to fraud charges. Diana is of course delighted but she has more pressing matters - Tom's threatened bungee jump. She agrees to marry him if only to stop the jump from going ahead but insists on her own pre-nuptial conditions.

After confiding her doubts about marriage to Sarah, Diana has a raucous hen night with male strippers whilst Tom's stag night is a very staid affair. The befuddled Dennis Sparrow is to conduct the two wedding ceremonies separately but due to a double booking involving a funeral, a double wedding is on the cards after all - despite Marion's efforts to sabotage Tom's marrying Diana.
