With the show's latest season ending next week, it is already expected that the episode will be a very dramatic one.

Emily Wickersham has been a cast member of "NCIS" for eight years already. she plays Agent Ellie Bishop.

For years, the CBS crime drama has teased that she and Agent Nick Torres will be getting together but it still hasn't happened yet.

However, the teaser shows what the fans have been waiting for for years.

In the short clip for "Rule 91," the two shared a very tender kiss. The moment was inserted in between the other events in the trailer, which also seemed to suggest that Bishop was going to be in trouble.

Katie Hines told Agent Timothy McGee, "Bishop is the last person to leak classified documents."

In another moment, Bishop also insisted that she's innocent, but then a judge says on her screen, "We are coming for you, agent."

At the end of the video, Bishop talks to Gibbs and asked him what Rule 91 is. He simply explains, "When you decide to walk away, don't look back."

It seemed to be a hint that Bishop is considering leaving NCIS permanently.

As of writing, the actress hasn't confirmed if the rumors are true.
