Shortly after season one of the CW series came to an end, Rose (who stars as Kate Kane/Batwoman) said in a statement shared in May that she "made the very difficult decision" to exit the show.
"This was not a decision I made lightly as I have the utmost respect for the cast, crew, and everyone involved with the show in both Vancouver and in Los Angeles," she said.
In an Instagram post shared days later, Rose said that "it wasn't an easy decision but those who know, know."
"I have stayed silent because that's my choice," she added.
Rose explained the reasons for her departure during an interview with Entertainment Weekly that was published in August.
The "Orange Is the New Black" alum said that her 2019 on-set accident, in which she underwent emergency surgery to repair two herniated discs after doing her own stunts for "Batwoman," factored into her choice.
Rose said that she returned to work days after her surgery and said that being the lead of a project, in general, is "taxing."
She also said that aside from the injury, COVID affected the show's production. Like many shows, the most recent season of "Batwoman" was cut short and not given a proper finale.
"You have time in quarantine and sort of isolation to just think about a lot of different things and what you want to achieve in life and what you want to do," she told EW. "I think for both [me and the producers], it was a great opportunity to have a dialogue about a lot of things."
Rather than recast the role of Kate Kane on season two, the show will introduce a new Batwoman named Ryan Wilder (played by Javicia Leslie)
