Events of Red Dead Redemption 2
As the Van der Linde gang head back from attacking the O'Driscoll camp, they come across Kieran. Kieran is seen fleeing on horseback. Arthur eventually captures him and takes him back to camp, and Dutch orders his gang to lock him up in one of the cabins and not give him food until he talks. Kieran tells them that he was part of the O'Driscoll gang unwillingly, and that he hates Colm O'Driscoll.
Horseshoe Overlook chapter
When the gang settles near Valentine, Kieran is seen tied up to a tree, looking malnourished and weak. The gang decides to interrogate him again and threaten to torture him, so Kieran then again tells them that he hates Colm. He then tells them that he knows where one of Colm's supposed safehouse is located. He leads Arthur Morgan and other members of the gang to the supposed safehouse of Colm's. In the climax of the assault, an O'Driscoll goon was about to shoot Morgan, but Kieran somehow managed to get a gun and gunned down the goon. Kieran was then taken back to the Van der Linde camp and was integrated into the gang.
Clemens's Point chapter
Kieran and Arthur later went to fish together next to the gang's camp.
Saint Denis chapter
At some point after the gang relocated into Shady Belle, Kieran was captured by the O'Driscolls. He was tortured and murdered by them after they found out the Van der Linde's location. After being mutilated, his body was then sent on horseback to the camp, tied up so that the dead Kieran was holding his head in his hands. Waves of O'Driscolls followed, attacking the house.
After the gunfight, Kieran was mourned by Dutch and the rest of the gang, and they had him buried somewhere close. His death shook several members, including Arthur, Bill and Mary-Beth.
- "Old Friends"
- "Paying a Social Call"
- "Blood Feuds, Ancient and Modern"
- "The Battle of Shady Belle"
- "Horsemen, Apocalypses"
- Based on dialogue in the mission "No, No and Thrice, No", Susan Grimshaw mentions that she hadn't seen Kieran around the camp recently, alluding to his eventual demise.
- His grave site can be found near Bolger's Blade. This can be visited after "Horsemen, Apocalypses".
