While the actor remained silent, recent reports have finally shed light on the truth behind his mysterious exit. Sources close to Harmon reveal that his departure wasn’t just about exploring new roles or taking time off—it was driven by a deeply personal decision rooted in family.

Fans are now reacting with overwhelming support, with many expressing even deeper respect for the actor. Though his absence is still felt on NCIS, knowing the reason has brought peace to many loyal viewers. Whether or not he returns in the future, Harmon’s legacy as Gibbs—and as a devoted family man—is more powerful than ever.
