Watch : Go Behind the Scenes of Benny Blanco, Selena Gomez and Becky G's "Te Olvido" CollabWarning: This article contains spoilers for the series finale of Wizards Beyond Waverly Place. At least that's what some Wizards Beyond Waverly Place fans are calling for after the Disney Channel series killed off Gregg Sulkin's fan-favorite character in a shocking series finale twist. After getting lost in a magical portal, Selena Gomez's Alex Russo found herself living in an apartment with BFF Harper Finkle (Jennifer Stone) on the day her boyfriend was supposed to propose to her. "I can’t propose to you," Sulkin's character told Gomez's during the Aug. 4 episode of the Wizards of Waverly Place sequel series. The ghostly revelation causes Alex to worry she is also dead—but Mason assures her otherwise.
