NCIS: Los Angeles’ most enigmatic agent is about to step into the light.

After seven years and 159 episodes of searching and coming up empty, Special Agent G. Callen (Chris O’Donnell) will finally learn what the G in his name stands for, EW has learned exclusively.

“It was always my intention to reveal Callen’s identity before the series ended,” executive producer Shane Brennan tells EW. “We’ve had a lot of fun finding out who Callen is, and from where he came. I wanted the audience to have the opportunity to enjoy that moment. And while he’s now discovered his identity, Callen’s odyssey isn’t over. In many ways, it’s just beginning.”
