Dembe (played by Hisham Tawfiq) has got to keep his cool on The Blacklist season 6 episode 16. He's been keeping a piece of vital information from Red (played by James Spader) that has been making him paranoid.

According to the episode synopsis for The Blacklist season 6 episode 16, Red will be testing the people around him to find out who turned him to the authorities earlier in the season. Now, this has Dembe growing concerned because he knows it was Liz (played by Megan Boone) who had a hand in Red's arrest.

Dembe is aware that there will be madness once Red finds out the betrayal. So, as much as possible, he's got to keep this information under wraps. However, Red has a few tricks up his sleeve that could finally reveal the truth. Will Dembe be able to outwit him, though?

Meanwhile, elsewhere in The Blacklist season 6 episode 16, Liz will be working alongside Ressler (played by Diego Klattenhoff) to look for a Blacklister. Known as Lady Luck, this person is capable of wiping out someone's gambling debts for a steep fee. 

The Blacklist season 6 episode 16 will air on Friday, April 12. The show has five more episodes to air after this before the season closes its run.

Last Friday's 15th episode, on the other hand, focused on the grief of Aram (played by Amir Arison) over losing Samar (played by Mozhan Marno). Feeling quite emotional, he took out his anger on Red who was, thankfully, a lot more understanding of what Amar is going through.

Arison told TV Guide that this grief would carry on in a few more episodes on The Blacklist. However, viewers will know if his character is slowly doing alright by looking at Aram's wardrobe. 

"He often wears purples and pinks, and they're not going to be bright right away," the actor revealed. "So, when you see Aram wearing bright colors again, you'll know he's back to being himself."

Marno announced she was leaving The Blacklist after five seasons to move on to the next chapter of her career. The actress posted a statement on her Instagram to thank the people she worked with and the fans that followed the show. 

Arison, however, believes that there may still be a chance for Samar to return. Her character wasn't killed off, and there are still many things that the writers can create from her storyline.
