Som Bellatrix säger i kommentarerna är detta Wizards of Waverly Place: The Movie . Det premiärde på Disney Channel 2009, så det är ganska rättvist att kalla det ett speciellt avsnitt av showen. Här är de relevanta detaljerna, till den punkt som du kommer ihåg:
The Russo family, Alex, Justin, Max, and their parents Jerry and Theresa are preparing for a vacation to the Caribbean. [...] Once in the Caribbean, the family meets a boy working at the hotel that Alex instantly develops a crush on. [...]
Later, after Alex was about to use a spell on her mother to convince her to let Alex hang out with the boy from the hotel, she gets caught, leading up to a heated confrontation with Theresa. Theresa tells Alex she is grounded for two months, which means she is forbidden to use magic and go out on dates or parties, As a result of this Alex, in a fit of rage, wishes that her parents had never met. The smuggled full-wizard wand and spell book, which Alex was holding at the time, grants her wish. As a result, Jerry and Theresa do not remember Justin, Alex, Max, and they don't know each other.
