Tim walked through the mostly empty halls of Gotham Academy, his backpack slung on one shoulder barely half-zipped. His posture was horrid and his walk was faster than usual to keep him awake, though the occasional dragging step did occur.

Tim couldn't help but calculate how long he had been awake... 56 hours, damn, that's more than he thought.

He blinks quickly a couple of times, then before he knows it, he's almost on the floor in someone's arms, 'Microsleep', he quickly realizes.
