Jack Cabot

Jack Cabot is a scientist in Fallout 4.

Background
Jack has been studying an ancient artifact that supplies his family with a serum to defy aging. He lives in the Cabot House with his mother and sister. The house is guarded by a sentry bot and the Sole Survivor is not allowed to enter unless they either pass two speech checks at the intercom, or they have received the relevant quest given by Edward in Bunker Hill.

Other interactions
The player character might have a random wasteland encounter in which Jack and Edward appear either in the player character's settlements or on the road. Jack offers to purchase any fiber optics the player character might have, which are necessary for a research project he will not discuss.

Effects of player's actions
If the player character sided with him during the quest The Secret of Cabot House, Jack will provide caps and, after an in-game week has passed, Lorenzo's Artifact gun. Should the player visit Parson's after this point, Jack may appear older.

Appearances
Jack Cabot appears only in Fallout 4.

Behind the scenes

 * The Cabot family is based on one of "Boston's First Families" the actual Cabot family. (John and Joseph Cabot) They were a very well-off family of shippers and traders, who moved to Boston in the 1700's.
 * Jack Cabot's appearance and mannerisms are based off real-life rocket scientist Jack Parsons, known for his experimental work with rocket propulsion in the 1940's and for being a leader of the OTO, a religious group which practices magic and rituals.
