You must have met Luke and decided to go to the gym with Alec instead of studying.
Well, I don't know if a "Deacon" is really in-game, but when checking the 1.5 guide, I see that there's a Deacon, but not a Jason, a guy that you can meet when preferring to go get something to eat rather than doing something else, I don't remember what. So, I don't know if Deacon = Jason, and it's a typo, or there's really a Deacon, and Jason will not have a route and was here just for fun
