We don’t want to give too much away, but let’s just say Gibbs is no longer alone.”
Added Harmon, “I’m very proud of the storytelling that David and Gina are doing on Origins. They continue to push boundaries and dive deeper into the characters’ backstories. They came to me with an idea for Gibbs that I liked, and it seemed like a good time to check in with him. I hope fans enjoy it.”
The crossover event begins on Origins will Gibbs (Austin Stowell) and the NIS team investigating the small-town death of a naval officer in the ’90s. Then, that case is unexpectedly re-opened in the present day on NCIS.
