Will this be the year that Callen (Chris O'Donnell) finally learns the truth about his family on NCIS: Los Angeles? And if so, what price will he have to pay?

Season 7 kicks off with a small time jump, picking up three months after the end of Season 6, when viewers learned that Callen's presumed-dead father is actually alive. And it's only a matter of time before Callen makes the same discovery. "The very heart of what this show is is Callen's search for his family," executive producer Shane Brennan tells TVGuide.com. "We are stepping closer and closer to finally giving Callen closure."

The premiere finds Callen butting heads with the rest of the team after someone from his past (whom we've met before) returns with a piece of information that Callen is "hell-bent" on looking into, Brennan says.

"Callen goes a little rogue," Brennan tells TVGuide.com. "It puts him in a fairly difficult position with Hetty. It puts him in a very, very difficult position with Sam - and as a result, puts him in a difficult position with the rest of the team. We've never seen Sam or Hetty in this position with Callen before. We've had situations where he's gone off the grid, but there's some pretty interesting conversations between Callen and Hetty and Callen and Sam about loyalty and being informed about what's happening."
