Mark Harmon may have departed NCIS three years ago, but Leroy Jethro Gibbs’ story lives on… well, at least in the past. The upcoming prequel show NCIS: Origins will chronicle Gibbs joining the law enforcement agency in 1991, with Austin Stowell playing the younger version of the character. We also recently learned that Kyle Schmid will play the younger Mike Franks, who’s leading the ragtag team that Gibbs is on. Now it’s been revealed who’s playing Origins’ third returning NCIS character, and it’s an actor who’s already appeared in the franchise.
