Someone at Bethesda is clearly a massive movie buff. You've already seen references to Blade Runner and Ted, so have one for Good Will Hunting too. Head inside the remains of the pre-war C.I.T building (if you dare), and head to the top floor. Inside one of the rooms, you'll find a dead janitor on the floor beneath a blackboard with the same symbols as those drawn by Matt Damon's character in the award-winning film.
