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.

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.

Emily then falls down the stairs and remembers back through a series of flashbacks the moments in her life that have shaped her future.
