That is a fascinating “what if” scenario that would have completely changed the course of Downton Abbey! The idea of Matthew and Sybil together is a popular fan theory that has circulated for years, but the truth is, the original script was never written that way. The love story between Matthew and Lady Mary was always the central romance and the intended heart of the series from the very beginning.
The core dramatic tension of the show’s first few seasons was built entirely on the classic “will-they-won’t-they” dynamic between Matthew and Mary. Screenwriter Julian Fellowes specifically crafted their relationship to embody the clash between old aristocratic tradition (Mary) and the new, more modern world (Matthew).
The Two Intended Love Stories
Julian Fellowes wrote the show with two very distinct and equally important romances that served different purposes:
- The Matthew and Mary Story: This was the main event. Their relationship was a slow-burn narrative, filled with obstacles and a powerful emotional pull. Their love was a symbol of two worlds colliding and eventually finding a way to coexist. The entire plot was designed to bring them together, marry, and then face the tragedy of his death. Their dynamic was the cornerstone of the series.
- The Sybil and Tom Story: This was the groundbreaking romance. Lady Sybil’s love for the family’s chauffeur, Tom Branson, was not a secondary plot. It was a bold statement about her progressive beliefs and a direct challenge to the strict class hierarchy of the time. This love story was a powerful vehicle for exploring themes of social change, and it was a separate, intentional arc from the beginning.
Where the Theory Might Have Come From
It’s easy to see why fans might have imagined a romance between Matthew and Sybil. Early in the series, Matthew and Sybil were often the two most modern-thinking members of the family. They shared a certain spirit of independence and a willingness to question tradition. They were both “outsiders” in their own way—Matthew as the new heir and Sybil as the rebellious daughter. These thematic similarities led to a few scenes where they shared a brief, meaningful conversation, which was enough to ignite the imaginations of fans who were captivated by the dramatic possibilities of a different pairing.
Ultimately, the power of Downton Abbey came from these carefully constructed, intentional love stories. The tension, the joy, and the heartache that came from the original Matthew and Mary plot are what made the show a timeless classic.
