The JAG reunion continues on NCIS: Los Angeles this fall.

Both Navy Capt. Harmon Rabb, Jr. (David James Elliott) and Marine Lt. Col. Sarah "Mac" Mackenzie (Catherine Bell) are back in the Season 11 premiere after that intense cliffhanger. CBS released photos of the two working alongside Callen (Chris O'Donnell) and Hetty (Linda Hunt) as each has an important role to play.

From lives in danger to a potential war to more 'JAG,' here are the loose threads we need wrapped up in Season 11.

In "Let Fate Decide," Callen and Sam (LL Cool J) work with Harm to apprehend spies aboard the U.S.S. Allegiance, just as they'd been doing in the Season 10 finale. Meanwhile, Hetty and Mac are still partnered up trying to neutralize a missile attack in the Middle East. As you'll recall, the finale ended with ISIS launching missiles from Iran into Israel and Saudi Arabia as part of a false-flag operation.

However, we don't see what's going on with Kensi (Daniela Ruah) and Deeks (Eric Christian Olsen) in these photos. In the premiere, they're still trapped in a mobile CIA unit in Iraq with Sabatino (Erik Palladino) while under attack by ISIS.
