Tahir Khaled's quest for revenge is nowhere near over. Sam Hanna's NCIS: Los Angeles nemesis will be back and ready to take lives in the season 7 finale.

Sam (LL Cool J) found himself on the wrong side of the terrorist when he brought Jada Khaled to safety in America, and recent episodes exasperated the feud when Tahir (Anslem Richardson) moved to target the Hanna clan. Hetty (Linda Hunt) released Sam's family from their safe house in "Seoul Man," but the OSP's unflappable leader may come to regret her decision when "Talion" rolls around.

"When Sam receives a distress code from his son Aiden (Tye White) that his school has been taken over by an extremist group, Sam, Callen, Kensi and Deeks rush to San Francisco to protect Aiden and free the hostages," CBS teased.

It very title of episode 24 smacks of danger. "Talion" draws it's name from the ancient Babylonian and biblical law that a criminal should receive the same injuries as those he inflicted, i.e. an eye for an eye.

We thought Sam's toughest episode was "Revenge Deferred," but perhaps we were wrong.

"Sam will be confronted with his most difficult case, the most difficult situation he's ever been in as an agent or as a SEAL," series creator Shane Brennan teased last year, according to TV Fanatic. "It has big repercussions. That's all I'm going to say."

Are you excited to see Sam's family take center stage once more? While we wait for Callen (Chris O'Donnell) and Co. to head to the Bay Area, NCIS: LA will shift the spotlight to Granger's (Miguel Ferrer) family. Prepare to see the Assistant Director and his North Korean daughter address the big reveal in next week's "Granger, O."
