It looks like CBS' procedural drama "NCIS: Los Angeles" is headed for some changes when it returns to the television screens for its eighth season on Oct. 2.

As reported by the International Business Times, "NCIS: Los Angeles" director John Peter Kousakis recently tweeted that junior field agent Kensi Blye, played by Daniela Ruah, will have a major plot change in the upcoming season.

"Kensi is challenged by a life-altering condition. Never seen anything like this before!"Kousakis said on his official Twitter account.

He also praised Ruah's performance, presumably to depict that "life-altering condition," calling the actress as "sensational."

It can be recalled that in "NCIS: Los Angeles" Season 7, Kensi decided to move in with her love interest, Deeks. Some fans are speculating that Kensi's "life-altering condition" will have something to do with the real-life pregnancy of Ruah, the actress depicting the character.

Earlier in the year, "NCIS: Los Angeles" executive producer Scott Gemmill also told TV Guide that the show's writers are planning to have Deeks engaged to Kensi during the eighth season of the show.

"I already know how we're going to do it. It's just, the fans have waited long enough that we want it to be worth the wait," Gemmill said.

With a possible engagement coming up next season, fans are also asking if Deeks and Kensi will soon have kids. To this, Gemmill said, "that's a real conversation that has to be had, and possibly more than once. I think it's one thing to say it now, but it's another thing as time goes on and situations change."

"Once they are officially engaged, then I think that conversation will come back again. And it's tricky, because neither one of them wants to give up their career, and can you have two parents in life-and-death situations on a daily basis? Is that proper parenting, or is that negligence in some way?" he added.
