WARNING: This article contains spoilers and predictions for NCIS: Los Angeles Season 11. Read at your own risk.

The premiere episode titled, Let Fate Decide, just kicked off a few days ago. As fans saw the possibility of Mac and Harm's official reunion after almost a decade, reports are now suggesting that NCIS: Los Angeles Season 11 is about to face its darkest moments yet.

Cartermatt has released a new episode preview for the current season. As per the publication, the upcoming fifth episode titled, Provenance, will be one of the season's most exciting and challenging installment. 

Nothing much has been revealed about the episode. Nevertheless, the recently released synopsis already sufficed the fans' thirst for previews and spoilers.

It has been uncovered that an all-new terrorist-related case will be the center of NCIS: Los Angeles Season 11 Episode 5. The crew, which will probably focus on Deeks, Kensi, Callen, and Sam, will track and hunt down a stolen painting.

An anonymous tip seemingly made its way to the department through "online chatter." It has been known that the stolen painting is worth $40 million, which will be sold on the black market.

The relationship between the artwork and the terrorist lies within the money that will be obtained from the selling point. It has been teased that it will be used to fund a future terrorist attack, most likely somewhere within the Los Angeles vicinity.

Aside from these details, no further enlightenment has been shed upon the episode. Nevertheless, a popular actress is said to join the cast of NCIS: Los Angeles Season 11. 

In the upcoming Providence episode, Code Black and Falling Skies star Moon Bloodgood is revealed to play an integral role. As for the exact character that she will be playing, little information has been shared about the matter. 

Reports are claiming that she might be the anonymous tipster. However, there is an unlikeliness in this scenario. It might be more fitting is she will play an antagonist role in the episode.

Cartermatt somehow believes that she might be the art thief of the stolen piece. And it is also possible that she might be the broker of the artwork. 

Whatever the case, though, Moon Bloodgood's arrival on NCIS: Los Angeles Season 11 is a sure treat for the fans. Although guest stars are very much apparent in the course of the show, having new faces still excite the fans.

There will be three more episodes to air first before fans see Moon Bloodgood's entrance. The Providence episode is set to drop on October 27, on CBS.
