Sarah Clarke
Sarah Clarke was a television veteran when she first appeared on NCIS, having established herself as Nina Myers on the action show 24. She was also Bella Swan’s mother in the 2008 film Twilight! NCIS would tease her return with a guest appearance, but her character, FBI Special Agent Tess Monroe, would only appear in recurrent roles. You’ve probably seen her on Trust Me, Covert Affairs, and the Amazon drama Bosch since then.

Laura San Giacomo
Laura San Giacomo appeared as Dr. Grace Confalone on NCIS several times, but she remained a minor character in the NCIS universe. In the show, she became Gibbs’ confidante and someone he sought to for counsel. Although we rarely see Laura in movies or TV series these days, her two most popular efforts are Beautiful Woman (where she played Julia Roberts’ best friend) and Just Shoot Me! We hope to see her on NCIS or elsewhere soon!
