The NCIS: Los Angeles team managed to rescue Kensi from Afghanistan last year, but the psychological repercussions of her time abroad won't dissipate quite so quickly.

Kensi (Daniela Ruah) helped Deeks (Eric Christian Olsen) pick up the pieces after his unscheduled dental surgery last season, and Deeks will be on hand to deal with Kensi's White Ghost repercussions in season 6.

"I know that she's obviously still suffering from what happened to her in Afghanistan," Olsen told TV Fanatic. "The body reacts in really bizarre, interesting ways [due to] traumatic experiences. Deeks went through that and I think Kensi is going through her version of that, and it comes in waves, it comes in flashes."

One of these flashes will happen early in the season, and it will prompt an important Densi conversation.

"I think we have one of those moments where Kensi's character in a very typical Kensi way, she tries to fight it," Olsen explained. "But they end up having this kind of conversation about it and it's one of my favorite scenes that we've done so far about their relationship, about navigating the walls of her defense."
