A professor at Stanford calls the government when an assassin comes after him. They ask for Chuck's help, but he refuses because the professor was one of the people responsible for getting him expelled. But when Chuck gets a flash of himself, he searches for the professor hoping to find out why he's in the Intersect System. Written by Jesse Sanchez
