"Harper Knows" is the eighth episode of season two of Wizards of Waverly Place, and the 29th of the overall series. It first aired on November 23, 2008.



It is Harper's birthday, and Alex forgets, again. This is because of a PopCon, a popular comic book and movie convention. The Russo Family is on an assignment at PopCon, where they are on the look out for rogue wizards who may be using their magic. Alex and her siblings go as a special wizards-in-training assignment and Harper comes along for the costume contest. Alex and Harper get in a fight after Harper gets upset at Alex, for forgetting her birthday. Alex begins to feel guilty for lying and keeping secrets, and she's tired from using up all of her energy to keep the secret. Then when Justin and Hugh Normous confront her and decide to take her in, she teleportes leaving Justin and Hugh with the now charmed Battle Diva costume.

Harper's costume then gets mixed up with the charmed version because of Alex. During the contest, Harper begins to float. The wizard police are able to cover it up using ropes. Alex eventually decides to tell Harper that she is a wizard, and convinces her by taking her to space and giving her a cupcake in space. In the end, the Russos show Harper the magic lair while Jerry and Justin plot to erase Harper's memory using a spell. However, this never comes to pass.
