The Werewolf's Origin: Mason Greyback's Crucial Role in the Original Series

Mason Greyback's introduction in Season 3 of Wizards of Waverly Place marked a significant turning point for Alex Russo’s (Selena Gomez) romantic life. He was a purebred werewolf, which immediately set him apart from Alex’s previous mortal boyfriends.

The Art Class Meets the Supernatural

Mason first appeared as an art student, quickly captivating Alex with his charming personality and talent for painting. Their relationship was defined by a passionate, yet turbulent, supernatural dynamic. The fact that he was a werewolf, a mythical creature, was a constant source of drama and comedy for the Russo family.

The Infamous Werewolf-Vampire Feud

A major storyline involved Mason's centuries-old rivalry with Juliet van Heusen (Bridgit Mendler), Justin Russo's vampire girlfriend. In a shocking confrontation, Mason was forced to transform into a full wolf and bit Juliet, which caused her to turn mortal. In retaliation, Juliet scratched Mason, causing him to permanently turn into a full wolf until Alex and Justin found a magical cure. This demonstrated the extreme sacrifices he was willing to make for Alex.

The Final Kiss

Despite the constant drama—including being turned into a dog and a brief breakup—Mason and Alex ended the original series on good terms. Mason was last seen as a human, fully committed to Alex, solidifying his status as her most major and enduring love interest. Their relationship was a fan favorite, establishing a strong foundation for his potential return in the sequel.

Will Mason Return? The Massive Hints for Wizards Beyond Waverly Place

The question of Mason Greyback's involvement in the sequel series, Wizards Beyond Waverly Place, is one of the biggest mysteries currently captivating the fandom. While no official confirmation has been made by Disney, the evidence for Gregg Sulkin's return is overwhelming and points to a major reunion.

1. On-Set Reunions and Cast Teasers

Multiple sources and cast members have heavily hinted at Mason's return. David Henrie, who reprises his role as Justin Russo and is also an executive producer, has teased Gregg Sulkin's appearance.

This behind-the-scenes activity, while not an official press release, strongly indicates that Mason Greyback will make at least a guest appearance, possibly in a climactic episode like the Season 1 finale.

2. The Alex Russo Conundrum: Who is Billie's Father?

The plot of Wizards Beyond Waverly Place centers on an adult Justin Russo, who has chosen a normal, mortal life, and his family. However, Selena Gomez is confirmed to return as Alex Russo in a guest-starring role. A major plot point involves Alex introducing Justin to Billie (Janice LeAnn Brown), a young wizard she is mentoring.

Crucially, some fan theories and early spoilers suggest that Alex Russo is Billie's mother. If this is true, it raises the urgent question: Who is Alex Russo's husband and Billie's father? Mason Greyback is the most likely candidate, as he was Alex's main and final love interest in the original series. His return would not just be a cameo but a pivotal moment confirming the ultimate fate of the "Jalex" (Justin and Alex) sibling rivalry and the "Malex" (Mason and Alex) romance.

3. The 'Purebred Werewolf' Entity

Mason's status as a purebred werewolf is a key entity that adds a unique layer to the magical world of the show. Unlike a regular werewolf, Mason's transformations were often tied to his emotional state or a magical curse, making his character a powerful tool for dramatic storytelling. If he returns, the sequel can explore what it means for a purebred werewolf to be married to the family's most powerful wizard, Alex Russo, and how they raise a potential new generation of magical children.

The Mason Greyback Legacy: Topical Authority and LSI Entities

Mason Greyback represents a critical element of the Wizards of Waverly Place legacy: the integration of non-wizard supernatural beings into the Russo family's world. His storyline expanded the show's topical authority beyond basic wizardry, introducing concepts like werewolves, vampires, and magical curses.

Key entities and themes related to Mason Greyback:

• Malex: The popular portmanteau for the Mason and Alex relationship.
• Werewolf Transformation: The dramatic process Mason undergoes, often leading to humorous or intense situations.
• Purebred Werewolf: A rare status that gives him unique powers and vulnerabilities.
• Alex Russo's Love Interests: Mason is often discussed alongside Alex's other boyfriends, notably Dean Moriarty and Chase Ripley.
• The Russo Family: His connection to Alex makes him an honorary member, contrasting with the mortal world of the sequel.
• Justin Russo: His rivalry and eventual truce with Justin (David Henrie) is a core relationship.
• Juliet van Heusen: The vampire who was involved in the dramatic love triangle/feud.
• The Wizards Competition: The main event of the original series that determined Alex’s wizard status.
• Waverly Place Sub Station: The iconic setting where the Russo family lives and operates.

The potential return of Gregg Sulkin as Mason Greyback in Wizards Beyond Waverly Place is more than just a nostalgic cameo; it is a critical piece of the puzzle that will define Alex Russo's adult life. Fans are eagerly anticipating the moment the charming artist and werewolf steps back into the wizarding world, confirming whether he and Alex truly got their "happily ever after."
