Katrina Law joined NCIS as Jessica Knight in Season 18, and it didn’t take long for her to leave a mark. Fierce, intelligent, and unafraid to speak her mind, Knight has become a fan favorite — and a crucial part of the show’s next chapter.
Law’s background in action-packed roles like Arrow and Spartacus gave her the perfect mix of physicality and poise. But what makes her stand out on NCIS is her emotional range. She can chase down a suspect and then deliver a gut-punch line about loss or justice — all in the same scene.
Off camera, Katrina Law is every bit as dynamic: a martial artist, singer, wife, and mom. She brings joy to the set, shares behind-the-scenes laughs with fans, and gives NCIS a much-needed spark of new energy.
She’s not just the new girl — she’s the future.
