Casting rumors are swirling around A Knight of the Seven Kingdoms Season 2, and this one’s got Game of Thrones fans genuinely excited. According to a rumor circulating on social media (via House the Dragon fan page), Lucy Boynton (Bohemian Rhapsody, Sing Street) is in talks to join the HBO spinoff’s second season. While nothing’s been officially confirmed, the internet is already buzzing about which character the accomplished actress might play—and based on the reactions, there’s a strong feeling about which Dunk and Egg character she could be joining the cast as.
Quick read:

Lucy Boynton rumored for A Knight of the Seven Kingdoms season 2
-
Bohemian Rhapsody actress in talks for significant role
-
Speculation centers on character Rohanne Webber from novellas
Oscar-caliber talent heading to Westeros
Lucy Boynton has built an impressive resume since her breakout role in Miss Potter (2006), with standout performances in Singing Street (2016), Murder on the Orient Express (2017), and most notably as Mary Austin in Bohemian Rhapsody (2018), where she brought nuance and emotional depth to Freddie Mercury’s first true love.
The actress has proven she can navigate both intimate character dramas and sweeping period pieces—exactly the kind of range that A Knight of the Seven Kingdoms requires. If she does join Season 2, she’d be joining an already stellar ensemble cast that includes Peter Claffey and Dexter Sol Ansell from the first season.

The character everyone’s speculating about
Based on the rumor and the enthusiastic fan reactions, Boynton appears to be in contention for Rohanne Webber, a significant character from George R.R. Martin’s novellas who becomes part of Dunk’s story during the second tale, The Sworn Sword. Without spoiling anything, Rohanne is a character with considerable agency, complexity, and dramatic potential—the kind of meaty role that would appeal to someone like Boynton.
The character demands an actress who can convey steel alongside vulnerability, and Boynton’s track record suggests she’s more than capable of bringing that kind of layered performance to Westeros. Fans are already imagining how she’d play the role, and the response has been overwhelmingly positive.
