"The Blacklist" Season 4 spoilers reveal that fans should brace themselves for more plot twists ahead. In a recent post on Twitter, Hisham Tawfiq shared that he just received the script for the upcoming episodes of the NBC series.

Tawfiq advised fans to prepare their jackets and things they might need because there is a "storm" coming in "The Blacklist" Season 4. Tawfiq added that there are "crazy" stuff ahead for the characters after the big reveal during the winter finale.

As Carter Matt recaps, "The Blacklist" Season 4 winter finale revealed that Dembe was the one who poisoned Red. This is one of the show's biggest betrayals after Mr. Kaplan, as Dembe has been Red's trusted ally and righthand man throughout the series.

The publication notes on the possibility that Dembe was only set up and "The Blacklist" Season 4B may ultimately reveal who was truly responsible for the poison. Mr. Kaplan may also have a hand at Red's recent struggles.

Meanwhile, Pop Matters states that "The Blacklist" Season 4 should be able to find ways to make the stories more interesting. The recent betrayal isn't exactly the show's first time seeing Red get betrayed by someone he trusted.

The publication also notes that "The Blacklist" Season 4 has been struggling when it comes to introducing new villains. If the show gets renewed for Season 5, the outlet suggests on killing one or two of its lead characters for good, doing a major reset on the show and maybe revealing Red and Liz's true connection.
