NCIS: LA Season 5 Spoilers: Deeks And Kensi Relationship Will Face Another Challenge! Executive Producer John Peter Kousakis ‏Teases Major Spoiler!

So far, NCIS: LA season 5 executive producer John Peter Kousakis has been giving fans teases on what to expect when the show returns tomorrow.

From what Kousakis revealed, it looks like NCIS: LA popular love team - Deeks (Eric Christian Olsen) and Kensi (Daniela Ruah) - are about to face some major challenges in their relationship.

Before the show went into a hiatus last year, fans saw how the relationship between Deeks and Kensi grow from being partners to lovers.

But, right before they are about to start a relationship, Hetty (Linda Hunt) decided to put Kensi in an undercover mission in Afghanistan to find the "White Ghost."

Now, it looks like the two will face more challenges before they can truly start a real relationship.

A few days ago, Executive producer John Peter Kousakis revealed some intriguing details about Deeks and Kensi's relationship.

On January 7, Kousakis tweeted that "Densi" loveteam will be in jeopardy on episode 18.

These revelations from Kousakis is somewhat coincide with EP Shane Brennan's revelation last September 2013 when he talked exclusively to Xfinity.

When Xfinity asked Brennan what kind of changes to expect from "Densi's" future, Brennan revealed that the two would have "a very, very bumpy ride."

Brennan further added, "A little later in the season, around Episode 10 or so, things take a fairly difficult turn for both of them. About eight episodes later, there is a pretty shocking revelation that deeply affects both of them and has them both questioning everything about their relationship, particularly Kensi."

This spoiler revealed by Brennan coincides with Kousakis tweets, particularly on what's going to happen on Episode 18.

What do you think will happen to Kensi and Deeks?

NCIS: LA season 5 returns with episode 13, "Allegiance" tomorrow, Jan. 14 on CBS at 8pm.
