The season 4 episode where Charles proposes to Diana is “Fairytale.”
It is the third episode of The Crown’s fourth season, released on Netflix on November 15, 2020. Set in 1981, the episode follows Charles’s proposal to Lady Diana Spencer and her difficult adjustment to royal life before their wedding.
The title reflects the public image of the match as a royal fairy tale, while the episode deliberately contrasts that image with Diana’s isolation, strict royal tutoring, eating disorder and growing doubts about Charles’s relationship with Camilla Parker Bowles. The wedding ceremony itself is not shown in full, although Diana’s recreated wedding dress appears near the end.
A common mix-up is choosing “Favourites,” “Gold Stick” or “Avalanche,” which are also season 4 episode titles or associated episode references. “Fairytale” is also notable for Emma Corrin’s acclaimed performance as Diana and for its recreation of the iconic wedding dress.
