TV Insider’s Season 5 theory is that Francesca or Michaela may marry a man to preserve the Kilmartin estate and earldom while the women stay together; Francesca is likelier. The writer doubts a legal union between them is possible in the show’s world.
Season 4 revealed Francesca is not carrying her late husband John’s heir, bringing succession of the Kilmartin estate and earldom into question. Netflix has said she will return to the marriage mart; the article floats Christopher Anderson, Lord Marcus Anderson’s son, as a possible husband.
Showrunner Jess Brownell has described Francesca and Michaela’s season as a story of “queer joy,” while saying the pair will still face obstacles and ultimately have a happy ending.
