Wondering about My Plain Jane

ScreenRant features My Lady Jane in detail so beware of spoilers.

Despite what My Lady Jane's ending sets up, the source material does not align with a second season, or at least not a traditional one. Although Ashton, Hand, and Meadows did write three Lady Jane books, the second book does not follow Jane and Guildford. In fact, it follows a completely new Jane. Published in 2018, My Plain Jane tells the story of Jane Eyre, a young woman who becomes a governess and falls in love with a mysterious man, but not before she embarks on a hunt for hidden secrets and creepy ghosts.

In this way, My Lady Jane season 2 could continue Jane Grey's story, but it would do so without the support of the source material. As far as the books go, Jane and Guildford's story concludes at the end of book one. If Prime Video was going to be book-accurate, it would pivot to Jane Eyre in season 2. Ultimately, this puts the streaming service in a strange position. It could go back on its season 2 set up and delve into a new Jane-centric story, or it could continue Jane and Guildford's story from scratch. [...]

Regardless of where My Lady Jane goes in the future, it will be great news to get a season 2. The first season was so strong, it would a shame for it to end so soon. Plus, whether season 2 features Jane Grey or Jane Eyre, the series will likely continue to be a great watch. No matter what, the future of My Lady Jane is bright. (Megan Hemenway)

The Hindu discusses the series too.

The ending hints at a season 2. Though it might not be about Charlotte Brontë’s Jane Eyre as the second of The Lady Janies series, My Plain Jane, was, it is not a bad thing as spending more time with Lady Jane, her royal cousins, scheming parents, silly siblings and lovely husband.
