Behind was sitting his best friend Leo that he doesn't even know. Jason didn't remember anything before he woke up. The coach was looking at him for a long time, and he was thinking the same thing too. The coach a the students went on a field trip. When they arrived, the coach stopped Jason and asked who he was. Jason told him that he doesn't remember anything that happened before he woke up. So the coach told him that he had never seen him in his class. And the coach told him that he senses a monster in between the students and told him to watch out. Then Piper went up to Jason and started walking in with him. Then Dylan came and started to talk to Piper, Piper didn't like him. Jason got kind of jealous when he saw Dylan dragging Piper away from him. Then they started crossing a bridge. If you looked down, it felt like you were hundreds of miles away from the ground. If you fell from there, you would probably die. Then suddenly, a storm occurred and started blowing strong winds toward the coach, Leo and Jason. Dylan and Piper guided the other students into the room and opened the door for the coach, Leo and Jason to go in, But then, Dylan closed the door tightly and threw Piper away from the door. When Jason saw that, he was pretty angry. Then the coach, Leo and Jason started running towards the door and the wind direction. The wind was too strong that they couldn't hold themselves. Dylan appeared in front of the coach, Leo and Jason. It came out that all this time the monster coach sensed was Dylan. Dylan was a storm spirit that wants to kill Piper, Leo, Jason and the coach. Then Jason found a gold coin in his pocket and took it out. He threw the coin into the air and spin it, then the gold coin turned into a golden sword. Dylan used his sword and hit Dylan on the head.
