Rumors about a Killing Eve spin-off zooming in on Carolyn's character entered circulation ahead of the Season 4 Finale of Killing Eve. Sally Woodward Gentle, the executive producer of Killing Eve, addressed the rumors in an interview with Deadline.

"Yeah. I mean, it’s really the same as all the others. We got lots of thoughts, but nothing has firmed up at all, and it’s quite a long way off," Sally said. "So, there isn’t really anything else to say yet."

According to Town & Country, the spin-off is in the earliest stages of its development — and it has yet to receive the green light. Fiona, the actress who has played Carolyn since Season 1, Episode 1 of Killing Eve, told The Sun that she is currently focusing on another project.

"At the moment, I'm busy doing something else, and I have a few other things coming up," Fiona said. "Maybe if it lingers, I certainly would think about it, because I enjoy her and I miss her so much already."
