Dutch asks Arthur to talk to him about the trolley robbery that Bronte tipped him off about. Arthur asks if it will be just the two of them, but Dutch tells them they'll need a third. Arthur recommends Lenny while Dutch asks why not Micah. Arthur tells him that Micah is too reckless and that they'll never get along. Soon after, Dutch notices an odd figure riding a horse into camp at a trot. Mary-Beth screams and recognizes Kieran, who has been decapitated with his eyes gouged out after he disappeared after the party following the return of Jack.
Shortly after a horde of O'Driscolls attack the camp. Arthur shoots at the first wave of attackers from the porch, before being sent down to the front door to defend the main area of the camp. He is then sent to find Sadie, who kills three O'Driscolls with a Knife. Then they kill the rest of the O'Driscolls along with the others, and the mission ends. Dutch then asks Charles, Swanson and Pearson to bury Kieran whilst Arthur and John clear out the corpses, but not before telling Dutch how hateful Colm is. Arthur has an individual Diary writing cutscene, where he regrets not being able to save Kieran's life. Kieran's death has a lasting impact on the camp, notably Arthur for failing to save him, Bill because he had grown fond of him, and Mary-Beth who had implicitly fallen in love with him.
