In the past episode of "The Blacklist", the return of Katarina Rostova's return (Lotte Verbeek) was hinted but she is seen in a different light, a villain. She gets to warn Raymond Reddington (James Spader) and Liz Keen (Megan Boone) sort of mourn for his passing. Is that really the end of Reddington?

Doubts loomed that a spy dwells within the team of Red but the suspicion is a disappointment because the  mole is in the person of Samar (Mozhan Marno). Red does everything to protect its interest against the traitor. Other suspects are Aram, Liz and Ressler, as published in News Every Day.

Fans justify that Samar is an FBI agent undercover but why is this necessary? There are many possibilities leading the alleged betrayal to Samar - and as soon as that is known to Red, he will not hesitate to disclose the finding to Harold (Henry Lennix) as shown in "The Blacklist" Season 4 Episode 9 teaser.

The probe for the hunt follows with the four suspects' background displayed onscreen. The very first one who is scrutinized is Ressler (Diego Klattenhoff), then Liz (Megan Boone) is next and Aram (Amir Arison) immediately followed on the hot seat. The last one verified is Samar and she is likely the main suspect.

Back to  Katarina Rostova, her fans worldwide are thrilled to watch her again and remembered how she was introduced by Harold to the FBI in Season 2. As viewers know that she is an Iranian-born Baloch and got into Mossad after her parents' traumatic ordeal suffered under the Iranian government that killed them, according to Movie News Guide.

"The Blacklist" Season 4 Episode 9 resumes on January 5, 2017 at NBC where it will be featured that the traitor in question endangers Elizabeth's life, as indicated earlier here on Jobs & Hire.
