Liz Keen (Megan Boone) continues to have trouble learning who to trust in the next episode of "The Blacklist" season 4.

In the previous episode titled "Gaia," Liz received a highly anticipated video chat from the person who claimed to be her father, Alexander Kirk (Ulrich Thomsen). The video showed the condition of her baby daughter, Agnes, who had been kidnapped by Kirk.

Liz specifically ordered her husband, Tom (Ryan Eggold), to avoid tracing the location where the video chat message was sent. But Tom decided to disobey her in hopes of finally rescuing their daughter. However, this made things worse since Kirk found out that their video chat had been traced. This led Liz to question her trust to Tom.

However, the list of people who Liz could give her trust to will grow shorter in the upcoming episode titled "The Lindquist Concern."

According to the synopsis from The Futon Critic, "Liz's loyalties are tested as Red (James Spader) takes action on an operation to intercept Alexander Kirk. Meanwhile the Task Force races to find a killer who targets inventors of revolutionary technology."

The trailer for the episode showed that while Liz could still not find it in herself to trust Kirk, she is also having a hard time trusting Red. In the promo video, Liz showed Red a result of a DNA test, telling him that she already found out that he was lying to her the whole time.

Additionally, the upcoming episode will see the return of actor Clark Middleton who will reprise his role as Red's skiptracer, Glen "Jellybean" Carter. This could mean that Red will ask him to look for a person in the upcoming episode. Does this mean Red will ask Jellybean to locate Kirk so that they can finally bring Agnes back to her parents?

"The Blacklist" season 4 episode 5 will air on NBC on Thursday, Oct. 20.
