The Blacklist Season 2 Episode 4 Spoilers: Red Tackles Dangerous Psychological Experiment; Cast James Spader Not Looking Too Far Ahead For The Series?

"The Blacklist" season 2, episode 4 spoilers show that Red and Liz will tackle a dangerous psychological experiment, as cast James Spader is not looking too far ahead in the series.

In "The Blacklist" season 2, episode 4 spoilers from Cartermatt, Mary-Louise Parker will guest star as Naomi who apparently knows something about Liz's past.

"Reddington (James Spader) has somehow made it clear to her at some point that she needs to keep quiet about everything. Liz knows 'very little' about what is going on, but this could be the episode where things start to change," it said.

Reddington has not forgotten yet about Berlin, however, particularly in last episode when he managed to secure a contract from the Indonesian government to that end. And Mary-Louise Parker's character could be an instrumental next step to help him get what he wants.

Of course, the episode wouldn't be complete without Red and Liz tackling a case of the day. This time, the two will set their eyes on Dr. Linus Creel, whom Red suspects as responsible for turning otherwise innocent and non-violent individuals into cold-hearted killers. Red thinks that it's due to a dangerous experiment and as is often in the show, he usually is right.

This is also the episode will Paul Reubens will appear as Mr. Vargas, considered to be a "muscle" for the underground organization who specializes in resolving delicate situations; just what his involvement with Dr. Linus Creel is still not clear.

"The Blacklist" season 2, episode 4 spoilers can be gleaned from the official synopsis: "Red thinks a dangerous social-psychological experiment may be taking place when several previously non-violent citizens become killers; Red has a complicated proposition for Naomi (Mary-Louise Parker) and her husband."

In an interview on "Late Night With Seth Meyers" last Monday, "The Blacklist" season 2 cast James Spader said that he's not looking too far ahead in the series, but he's glad that the show continually surprises him.

"I know the end game, but you don't know on a television series what the life span of the series is going to be, so you don't know if you have seven years to tell the story or whether you have two years," he said.
