Tom was pretty sure that he would never figure out how to find his way around Hogwarts. He'd only taken one flight of stairs and a corridor or two and already he was all turned around. He'd probably only get even more lost the more he tried to find his way back towards the central staircase, and then he'd miss classes and by the time they sent a search party out to find him he'd have died of dehydration...

OH! An adult! One of the professors, surely. He must know where he was going!

Tom turned in the direction the man was walking and hurried to catch up, intent on not just screaming at the man down the corridor.... Then Tom noticed that he was about to plow headfirst into one of the impressively scary suits of armor. Was it... was it moving?!?! Surely not! But yes, the hulking metal arms began to rise up in a defensive sort of posture, and Tom was certain that the poor professor was going to be attacked.

"LOOK OUT!" he bellowed down the corridor as he began to run.
