Alexander Kirk will soon be forced to come to Washington D.C. where Red and the task force will be waiting to get revenge on “The Blacklist” Season 3. While they try to take down Kirk for his role in Liz’s death, something is going to happen in the season finale, titled “Alexander Kirk: Conclusion,” that will put a team member in danger.

According to the synopsis, Red (James Spader) and the task force will get close to Kirk (Ulrich Thomsen), but a “shocking betrayal” will leave the team scrambling to rescue “one of their own.” The task force had to team up Halcyon, the group that tried to kidnap Liz (Megan Boone), in episode 22 in order to get to Kirk. Kirk knows secrets about Red that could shed light on his past and could also result in Kirk going after Red.

TVLine reported in April that “Red will experience a betrayal at the hands of someone very unexpected” in the Season 3 finale. The episode 23 promo video teases a few possibilities of who could be the one to turn on Red. While Red lines up his sniper to shoot Alexander Kirk, Ressler (Diego Klattenhoff) tries to stop Red from taking the shot. Red has promised to kill Kirk for taking Liz away from all of them, but Ressler could prevent this from happening.

“Do you want a bullet in Kirk’s head or one in mine?” Red asks Ressler. Ressler then takes out his gun and points it at Red’s head. Could Ressler be the one that betrays the task force?

Tom (Ryan Eggold) might also have other motives in the Season 3 finale. In Episode 22, Tom learned that his mother was Susan “Scottie” Hargrave (Famke Janssen) and she offered him a position with Halcyon. Tom turned it down, but he could change his mind. The promo video for the season finale shows Tom going rogue with the baby and it’s unclear where he was running off to. The last episode served as the pilot to a potential spinoff series focusing on Tom and the finale could further develop that story.
