Alan takes the sick and exhausted David to a house in Balquhidder, which is fortunately a house of the Stewart-friendly McLarens. The owner takes David in and puts him in a bed, and the area doctor is called for. Soon the whole surrounding community is aware that they are harboring Alan Breck Stewart and his accomplice. David lies in bed for just over a week, and within a month he is ready to move again.
While sick, David is visited by one of the sons of the notorious Rob Roy, Robin Oig. He is aloof, and not very mannered with the McLaren household owner. He speaks to David, thinking he is related to another Balfour, a gentleman, who once helped Oig's brother. David says he is not sure, and Oig turns to leave, rather disgusted that he has actually been talking to a lowbred boy. As he leaves he runs into Alan. The two recognize each other and Alan points out that Rob Roy attached the Campbell name to his own. After some tough talking, the two men prepare to duel, but the owner of the house intervenes and suggests that they duel by playing the bagpipes instead.
The two men play, and when Robin plays an air from Alan's country, Alan softens. They then exchanged airs the rest of the night, and become friends.
It is late August, and Alan and David finally choose to depart Balquhidder. They plan to head south, cross the Forth River into Stirling, and head into Edinburgh from there. They go to the bridge, but there is a guard. Instead, they sneak down the river to the small town of Limekilns. There, they enter an inn, where David pretends to be deathly sick. Alan pretends they are disinherited gentry, and a young woman takes pity on them. Alan also pretends that David is a Jacobite and likely to be killed if caught, but David counters this claim, claiming that it is all "a dreadful error" and that King George has no better friend in Scotland than himself. The young woman then borrows a neighbor's boat and rows them across herself. David is amazed by the woman's kindness.
David and Alan arrange to meet again later in the day, after David has spoken to his lawyer, Mr. Rankeillor. After wandering the streets of Newhalls (near Edinburgh) looking for Rankeillor. He finally runs into the man by accident, who takes him in, and David unloads the entire story. At the mention of Alan's name, Rankeillor pretends he did not hear the name, and insists that David must have said "Mr. Thomson." This is so he can swear under oath, in a court of law, that he never heard the name Alan Breck Stewart, should it come to a trial somehow. Many of the Highland names are changed the same way. After the story, Rankeillor takes David upstairs and gives him a change of clothes.
Yet another historical persona pops up, this time in the form of Robin Oig, the son of the famous Rob Roy Macgregor, one of the main characters in Sir Walter Scott's novel Rob Roy. In many ways, Stevenson is following in the footsteps of his fellow Scottish writer; Kidnapped involves many of the same clans and Highland-related issues as Rob Roy (which was published in 1818, seventy years before Stevenson's novel). The peace that is established between Robin and Alan is a pleasant break from all the Campbell-Stewart arguments that have filled the novel.
