In a surprise ending for the season we watch four separate outcomes for Laura's wedding day. Each is seen in the imagination of Emily and for a change we get to see the full talents of the actors get a chance to shine. However, this episode also leaves the question, which was the real thing?

Vacinnation is what eventuates from this episode after Malcolm is put under quarantine for small pox. As always, no one listend to Dr Burnley's advise and the children get Malcolm off the ship concealed in a coffin. However fear takes hold when they realise that Malcolm bought a boy of six, Robbie Burns with him as well whose mother died on the ship. The community won't accept Robbie, who is only six, but black and Emily's efforts to make him feel welcome fail. Vaccination begins but then Malcolm falls ill…

Small pox spreads through Blair Water and Robbie Burns dies. Trying to help as many as he can, Dr Burnley turns his house into a hospital. Ilse then also falls ill.

Emily and Ilse write an article ""Kicking the cat"" for the newspaper. The problems begin once people start taking the advice of the column and misunderstandings in love begins. Then Mr Carpenter returns and falls in love with Isabel Murray.

The truth is sometimes better left on the shelf and that is what Emily learns when she tries to overcome her writer's block. Deciding to write about what she knows she sees Rhoda's mother, Velma, as the perfect subject. ""Confessions of an Adulteress"" causing more problems when Rhoda falls for Harrison Bowles who is visting New Moon, soon Rhoda is losing control of all angles of her future.

Family bickering at it's best abounds at New Moon when it is left to Isabel, Laura, Emily and Jimmy. Isabel, who doesn't want to share wants to get the documents confirming this nulled and does everything she can. It is Uncle Malcolm who shows a side of him when Isabel goes too far to keep New Moon and he finally realises the truth about his family.

Overjoyed at finishing her first book she goes to see Teddy to see what he thinks of it. Only he breaks her heart when he is brutally honest about it bringing back memories of Dean Priest.
