Fans will see an unlikely team-up in "NCIS" season 13 with Vance and Gibbs on the same murder case. Titled "Double Trouble," the episode brings together the special agent and the NCIS director to get to the bottom of a crime that has something to do with someone very familiar to the latter.

As teased in the trailer for the upcoming installment, a former agent is yet to live through his agonizing imprisonment that Vance made happen. Hell-bent and driven by vengeance, he is "going after the head of the NCIS." In the promo, he will set him up and try to frame him.

Though Vance is no longer required on field duty, he gets hands dirty in this new case seeing that it involves an NCIS special agent he once put behind bars for filching evidence. With his past seemingly coming back to haunt him, he springs into action with Gibbs in this "NCIS" season 13 episode.

Although Gibbs and Vance are the ones on the field, the whole team goes hand in hand to know all there is to know about this haunting new case to eventually put their beloved director in the clear. The duo, however, seems to suffer issues as to who goes first and who is more capable of this and that.

And it looks like Vance's past won't be the only thing crawling back into the present. The history of other characters will factor big in the coming "NCIS" season 13 episodes. Rumor has it that Jeanne Benoit, who fans will remember as DiNozzo's sweetheart who last appeared in season 4, will come back.

Benoit and DiNozzo teamed up in season 4 to bring down the former's father, who deals arms and hides his crime by masquerading as a doctor. It is still unclear what brings Benoit back into the picture but whatever it is, it will apparently be revealed in an episode set to air around Thanksgiving.

"NCIS" season 13 episode 4 airs Oct. 13 at 8 p.m. on CBS. Viewers can watch a live stream of the episode via CBS All Access.
