That's right, folks, Deeks (Eric Christian Olsen) and Kensi (Daniela Ruah) are shacking up. Unfortunately nothing ever goes smoothly for the partners, and Kensi's affinity for clutter will be the least of their problems during Jan. 25's "Come Back."

"When Kensi and Deeks announce to the team they are moving in together, coincidentally, Hetty assigns them to protection detail for Jack (Matthew Del Negro), Kensi's ex-fiancé, who is in possession of a list containing important contacts in Afghanistan that people are willing to kill to get their hands on," CBS teased.

Whoops.

Jack made his first appearance during Kensi's Afghanistan arc, years after he dropped off the radar during their engagement. Known as the "White Ghost," Jack was nearly killed by Kensi under the orders of NCIS and the CIA, but after she missed her shot, she found out that he wasn't the nefarious traitor the government had branded him.
