Matthew Del Negro as Jack Simon, Daniela Ruah as Kensi Blye, and Eric Christian Olsen as Marty Deeks
On NCIS: Los Angeles' "Come Back," 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.
