"The Blacklist" Season 4 episode 15 spoilers tease on the upcoming confrontation between Reddington (James Spader) and Mr. Kaplan (Susan Blommaert), according to Screener TV. As seen in the latest episode of the NBC drama, Red figured out that someone from the inside was coming after him.

In the end, it was revealed that the person who hired Isabella Stone was none other than Mr. Kaplan. "The Blacklist" Season 4 spoilers tease that Red may soon come face-to-face with Kaplan, and it may either end in death or they may be able to sort things out.

The publication further notes that in "The Blacklist" Season 4 episode 15, Kaplan is decided to get revenge on Red and she will be determined to kill him for good. Of course, many fans would reason out that Red would not die in the show being that he is the lead character.

This reason entirely makes sense especially now that Tom Keen (Ryan Eggold) is nearing his departure from "The Blacklist" Season 4 to go onto his spinoff series, "Redemption." As Entertainment Weekly reports, the teaser promo for the spinoff drama offers explanation as to how and why Tom will be leaving the flagship series.

In the said promo of "The Blacklist" spinoff drama, Tom discovers that his supposed father, Howard Hargrave is still alive. Howard asks Tom to join Scottie's company to find out more about her, which may ultimately be Tom's reason for going on his own.
