Jack Cabot

Jack Cabot is a scientist living in the Cabot House in Boston in 2287.

Background
Jack is the son of archaeologist Lorenzo Cabot. In 1894, his father led an expedition to the Rub' al Khali in search of the fabled Ubar civilization. After Lorenzo returned to Boston from the Middle East with an alien artifact, he was found to have been granted supernatural abilities, yet also been rendered insane by the effects of the crown. For the safety of both Lorenzo and those around him, Jack, as superintendent, imprisoned the archaeologist along with his artifact at Parsons State Insane Asylum in 1898.

Jack devoted his life to investigating the artifact. His studies into the mysterious object subsequently resulted in the development of a serum derived from his father's blood that defied aging, halting and even reversing the process. In turn, Jack's special serums granted him and his family the ability to live for more than four hundred years. More than two centuries after the Great War, he continues to live in Cabot House with his mother and sister, furthering his research into a cure for his father's insanity.

Effects of player's actions

 * The house is guarded by a sentry bot and the Sole Survivor is denied access unless they either pass two speech checks at the intercom, or they have received a job offer to work for the Cabots from their messenger Edward Deegan in The Third Rail, Bunker Hill, or Dugout Inn.
 * 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, an object created with Lorenzo's Artifact. Should the player visit Parsons after this point, Jack may appear older.

Other interactions

 * If the player character immediately leaves after speaking with Deegan in the quest Special Delivery, Cabot may start following them across the Commonwealth. He will return to Cabot House once spoken to.
 * After receiving the artifact gun from Jack, if the player character chooses to ask what Jack will do now, Jack will say he will travel to the Southwest. His father was always convinced that there was another alien city buried somewhere below the Mojave Desert.
 * Should Jack survive, one may randomly encounter him in the Commonwealth with Deegan. If asked about his presence there, he will explain his desire to explore the world around him. Subsequently, he will offer to buy fiber optics from the player character, although he has only a small amount of caps on him. If asked as to the reason he needs them, he will only state that the public is not quite ready for his experiments.
