NCIS handed out a promotion to guest star Diona Reasonover. The actress, who appeared in three episodes of NCIS season 15 as Kasie Hines, has been upped to series regular for season 16, CBS tweeted. Reasonover's promotion comes in the wake of longtime cast member Pauley Perrette's exit during season 15.
Reasonover appeared in three episodes of NCIS season 15 as forensic scientist Kasie Hines. She shared scenes with Perrette in the episode "One Man's Trash" and appeared in the final two episodes of the season after Perrette exited the series. Perrette, who had been with NCIS since it began, announced her exit in October 2017.
