Wizards of Waverly Place 3x14

Harper is desperately trying to remember something, but she cannot. Alex offers to help Harper recall her memory, so she casts a spell on her. Harper then remembers: Stevie is a wizard, and she saw her cast a spell. Alex and Harper confront Stevie, and she confirms their suspisions by casting a spell in the ground that opens up a warp hole and a student falls in. Alex is happy that she has a wizard friend, but Harper feels left out.
