Stockton is the manager of a large caravan business operating out of Bunker Hill, running three caravan trade routes patrolled by: Trashcan Carla, Lucas Miller and Cricket. His caravan traders often man the Bunker Hill shop after hours. His caravan routes run throughout the Commonwealth and are connected to major towns and settlements such as Diamond City, with a few of also covering some small villages and farms. In addition to being an operative for the Railroad, Stockton is also the caretaker for the large safehouse in the utility basement below Bunker Hill that is home to many escaped synths.
Unlike other members of the Railroad, Old Man Stockton will not turn hostile should the Sole Survivor become an enemy of the Railroad.
It's possible for Old Man Stockton to be killed on his way back to Bunker Hill from the Railroad mission Boston After Dark; there have been several reports of him turning up dead in front of the BADTFL regional office.
If one initiates conversation with him enough times he will hand the player character a Nuka-Cola.
During Boston After Dark, Old Man Stockton will remark to a male player character that he was expecting "someone of the feminine persuasion." If the player character is female, he will remark that he was expecting "someone more heavily armed."
