The first season finale of NCIS: Los Angeles was titled "Callen, G." The second season finale this May was titled "Familia." The coming third season opener: "Lange, H."

As the team travels to Romania to search for Hetty, we learn more about the diminutive secret agent's past, while Callen discovers new information about his as well.

Could Chris O'Donnell's character and his mentor, played by Linda Hunt, are members of the same "Familia"? And will Hetty make it out of this predicament alive?

One thing is for sure: It will be an explosive episode, even by NCIS: LA standards, unfolding in real time a la 24. NCIS: Los Angeles returns September 20 after NCIS.
