21. Wizards of Apartment 13B

Complete story — includes the ending

Alex and Harper receive a flyer with an ad for an apartment. They meet the apartment owner, Dexter, who shows them Apartment 13B, which is on a secret floor for non-humans. They rent it, but Harper is forced to pretend she's magical by using a training wand that can only open things. Later at their apartment, they realize Mason lives on the same floor. Mason will stop at nothing to win Alex back; Alex tells him she does not want a boyfriend, but Mason is relentless. That night, Alex and Harper throw a housewarming party, which the whole floor attends, including Mason and Felix. Mason uses Harper's wand to open Alex's heart. However, she flirts with an ugly ogre because he's the first person she sees. Mason tries again, but makes Alex open her heart to Felix this time. Meanwhile, Theresa and Jerry trick Justin into going to Alex's apartment so they can have some peace and quiet. When Justin arrives, he fixes the mess Mason made by activating the child safety lock on Harper's wand and it is revealed that despite his eagerness to send her away, Justin misses Alex. Alex, freed from Mason's spell, is angry at Mason, and Mason, deflated, leaves. Outside their door, Dexter turns into Gorog when no one is looking. He wants revenge. Max keeps coming to the apartment uninvited, and when Harper and Alex kick him out, he encounters Gorog, who gives him a flyer for a free wizard camp. Max excitedly says he'll ask his parents about it.
