So it goes like this

Percy pov
So they just told me to get to the train to go to the wizard school that I half to walk through a wall. I let Ron go first. He pushed his carage  Infront of him and passed through the wall! I smirk at Annabeth and give her a look that says, I am gonna do something stupid and don't stop me. I rummage through one of my trunks on my carage and pull out to belts. I tye them to the front of the carriage and back up for a good running start. As I run forward, I leap onto the back of the carriage and grab the belts and yelling YAH! As I flicked the belts I passed straight through the wall, and I was able to control the luggage good enough to crash into a wall. When I look up from the ground I see annabeth laughing hysterically "gee thanks for the help" I grumble he gives me a hang up and says "seaweed brain."
