In October 1774, he takes Brianna on a three-day trip to the woods, where he shows her a skeleton of a mammoth.

In August 1775, when Brianna is taken by Neil Forbes and Stephen Bonnet, Ian interrogates Forbes and cuts his ear off. After Brianna’s return to the future, Ian misses her and the fact he could say anything to her.
Brianna encounters Stephen Bonnet in a bar in September 1769 in Wilmington. She notices that he is in possession of her mother’s gold wedding ring. He flirts with her, and when she asks for more information about the ring, he invites her to meet him at his ship, the Gloriana. When she arrives there, he rapes her, giving her the ring as payment for his enjoyment.
Later, when Bonnet is arrested for smuggling and is imprisoned in Cross Creek, Lord John Grey accompanies Brianna on a visit to see him. Grey waits outside as Brianna confronts the condemned Bonnet, revealing her pregnancy and telling him that he is the father. Bonnet then is aided in an escape attempt by Sergeant Murchison. The attempt is partially thwarted by Brianna when she knocks Murchison unconscious. Bonnet leaves Murchison to die as the building begins to burn, but at Brianna’s insistence, he relents and carries out the similarly incapacitated Grey. Once they are safely away, Bonnet tells Brianna he has a ship waiting. He asks if she’ll go https://rapidloan.net/payday-loans-il/ with him; she declines.

In August 1776, while pregnant with her second child, Brianna comes into his custody again. He does not rape her this time because he is afraid of having sex with pregnant women. Instead, he insists she sleep next to him in bed at night. She comforts him during his nightmares, which reveal his deep fear of death by drowning.  Bonnet then takes Brianna to Ocracoke, where he intends to sell her.
Roger and the Frasers succeed in rescuing Brianna and capturing Bonnet. Roger and Jamie give Brianna three choices: she can kill Bonnet herself, they will kill Bonnet, or they will deliver him to the authorities to stand trial. Brianna chooses the third option, expecting that he will be found guilty and hanged. 
Bonnet is found guilty and sentenced to death by drowning. Knowing this is his greatest fear, Brianna, accompanied by Roger, takes a boat out to where Bonnet is tied to a post in the harbor at rising tide. As the water reaches his neck, Brianna shoots him in the head.
