He is the owner of the Prescott Foundation, which makes many donations to various funds around Arcadia Bay. He is also the co-owner of Blackwell Academy, and donated money in order to own the Prescott Dormitory on campus.
Episode Three - "Chaos Theory" Edit
A scan of a letter from Sean Prescott to Principal Wells along with a reply can be seen on Wells' computer. On the table there is a letter inquiring why Principal Wells removed the Prescott family Crest from Blackwell. If Nathan was suspended in Episode 2, this letter will be replaced by a different one, in which Sean Prescott threatens to cancel financial aid to Blackwell Academy unless Nathan's suspension is lifted.
A thank-you note from Sean to David Madsen can be found in David's garage, thanking him for his help with Nathan. If Max sided with David in Episode 3, she can ask David for more information regarding this note, to which David will reply that he "gave Sean Prescott an estimate".
Max can ask several people at the End of the World Party about what they think of Sean Prescott. Luke Parker says that he once met Sean on a Bigfoots game. He speaks of Sean as being a "mean fucking bastard" and adds that he "explains Nathan".
- Nathan Prescott - Sean seems to have a very strained relationship with his son, sending him discouraging messages and emails. Sean obviously sees his son's emotional problems as an unnecessary burden, and is incapable of dealing with them. He suggests contacting Dr. Bill in order to fix Nathan's problems. He and his wife do not seem to care about the advice of Nathan's long-term therapist.
- Kristine Prescott - Sean and his daughter Kristine also have a strained relationship; Kristine calls her father "a bully who inherited power not wisdom" and encourages Nathan to either ignore or fight against him. She also says that the reason of her moving so far away was her father.
- Maxine Caulfield (Determinant) - If Max reports Nathan to Principal Wells, Sean will send a threatening message to her saying that she should "keep her mouth shut".
- Other Arcadia Bay citizens - The citizens of Arcadia Bay are well aware of Sean's greedy nature and shady acts. He has put a lot of people out of work, including the Homeless Lady and the fisherman.
- It is possible that Sean does not know about the true purpose of the Dark Room. However, this is unlikely. The vast amount of money he spent creating the bunker gives the impression that it has a higher purpose. The notion that the Prescott family knew about the oncoming weather-related trauma is possible. If they knew, it would make sense that they would begin a "Storm shelter Boom", and have the bunker ready for the upcoming emergency situation.
- One theory was that Sean is actually an alias of Mr. Jefferson. However, this has been disproved by Luke Parker's comments about him meeting Sean in person: "I met him once at a Bigfoots game...mean fucking bastard. Oh, man, he explains Nathan." Due to Luke knowing both him and Jefferson, it becomes clear that they are two different people.
