What happens when Harry gets into the elevator?

Harry and Murphy are in the elevator when Harry's magic affects the machine and it stops moving. Harry is angry at this when suddenly he realizes that the giant scorpion has managed to get into the elevator shaft and is on the cart. Harry uses his magic to create a wind that pushes the cart up to the top where it smashes the scorpion. Once it has smashed the scorpion the cart crashes down and Harry has just enough time to create a shield that keeps him and Murphy from being smashed from the impact of the landing.
