One image shows Agent Ressler (Diego Klattenhoff) being arrested which means that he is in trouble. Fans are confused since usually, he is the one arresting people and not the other way around.

There are also images for "The Blacklist" showing Ressler with a bit of blood on his forehead while holding a gun. He is also seen peeking around a corner to make sure that he is covered. Another image shows Ressler jumping over the fence and running with his gun. Probably he is after the bad guy but it is not yet known who that is.

It also appears that Liz and Samar (Mozhan Marno) will be working together. What are the two bad ass ladies up to? Liz is also seen talking to Red and it seems that she is investigating something. While Liz is doing her thing, Samar is seen in a hospital with a brain scan behind her. Whose brain scan is that?

The images also show Red and Dembe together wherein one photo shows Red pointing to Dembe (Hisham Tawfiq). It appears that Dembe doesn't approve of something since he looks mad in one image. What bothers Dembe?
