A fugitive must be captured in Bulgaria in the upcoming episode 6, titled "Her Spy's Harmed," of the second season of the American crime drama "Blindspot."

There's a fugitive whistleblower in Bulgaria that Weller (Sullivan Stapleton) and Nas (Archie Panjabi) must hunt down. Meanwhile, Jane (Jaimie Alexander) goes to a dangerous Sandstorm mission with Roman (Luke Mitchell). Reade (Rob Brown) and Zapata (Audrey Esparza), on the other hand, have to respond to an urgent matter before it's too late.

The promo trailer for "Her Spy's Harmed" shows Nas telling Jane that the terrorist organization Sandstorm could strike anytime, but they don't know when, where, and how it would happen. Jane assures Nas that she can turn in Roman, who is very close to confessing. Meanwhile, there is a huge secret that only Reade and Zapata know, which is close to getting exposed. Patterson (Ashley Johnson) tells Weller that there is no bug in Borden's (Ukweli Roach) office, but something much more interesting. Before the clip ends, one of the team members is injured after the explosion.

The previous episode, titled "Condone Untidiest Thefts," saw Zapata discovering that Reade may be responsible for the death of the coach. In an interview with Entertainment Weekly, executive producer Martin Gero talked about the dynamics of the two after the revelation.

The EP said, "Certainly it tests his relationship with Zapata. Reade is like a brother to her. She'll do just about anything to keep him out of jail — even if he did do it."

Brown, on the other hand, shared what the next move of the two will be in an interview with Collider. He said, "From there, they have to figure out how to get out of that spot, before more eyes are on the situation. The more people that see it, the more people who end up involved in it."

"Blindspot" season 2 airs Wednesdays at 8 p.m. on NBC.
