Wizards of Waverly Place - Make Predictions

This story is about a group of brothers and sisters who are trying to keep a secret. They are teenage wizards. They have special powers that the outside world shouldn't know about. They have lots of fun with they're magic but they are also very careless. Alex is 16, shes the middle kid and the irresponsible. Alex was in school playing around and acting foolish with her magic, and somebody saw her. I think she'll put some type of spell on him to make him forget what he had saw.
