Batwoman marked Rose's first full-time TV series gig, and the actress "was distressed by the long hours demanded of a lead TV role and did not acclimate well to life in Vancouver (where the show shoots)," reports TVLine. A source close to the show tells TVLine: “It wasn’t 100-percent her decision. It was a breakup. She wasn’t happy working on the show, and did that make her fun to work with? No. So everyone decided it would be in the best interests of the show, and for all concerned, if they parted ways. It just wasn’t a good fit.” The CW and Warner Bros. TV declined to comment on the reason for Rose's departure.
