Hugo turns back around to walk to the cafeteria, allowing himself to get lost in the feeling of music. A short walk later and he finds himself inside, nearly totally oblivious to his surroundings. The colored light continues shifting and changing, but doesn't grow in strength at all. He seems to be tuning out almost all noise from the outside world, right on up until he orders the mandarin chicken from one of the lunch lines and chooses a seat on the side of the cafeteria, facing inwards, where he simply watches the other students.
He doesn't relight his pipe, as that would be quite rude in a cafeteria.
