The Blacklist: Katerina Rostova returning in season 4 — exclusive

The Blacklist type TV Show network NBC genre Crime

Thriller

Lotte Verbeek will be reprising her role as Katerina Rostova in the fourth season of The Blacklist, EW has learned exclusively.

Liz Keen’s (Megan Boone) mother made her first appearance in season 3, appearing to Red (James Spader) in a vision of sorts in the wake of Liz’s apparent death. But we’ve seen glimpses of that character from the beginning.

“In the first two seasons, we used pictures and a few fragments of memory, but Lotte brought Katarina to life in ‘Cape May,'” executive producer Jon Bokenkamp says. “The fan response to that character has been great. The episode itself was a departure, but we’ve found some really interesting story opportunities as a result.”

The Borgias alum, who also starred on ABC’s Agent Carter, recently made a surprise appearance in Outlander‘s season 2 finale after an uncertain fate in season 1.

Verbeek will appear in at least two episodes in season 4, but how she’ll return — in flashback or otherwise — is being kept under wraps.

The Blacklist returns Thursday, Sept. 22 at 10 p.m. ET on NBC.
