"Blindspot" season 2 is back after a one-month hiatus. The newest episode may prove to be a nail-biter, with reports of some familiar faces coming back for the episode.

The Courier Daily recaps the synopsis of the new episode, with a title " Evil Did I Dwell, Lewd Did I Live." It seems that Weller, played by Sullivan Stapleton and Jane, played by Jaimie Alexander will meet Nas' source over at Sandstorm.

Viewers will remember what happened to Nas in the latest episode, with a title "Draw O Caesar, Erase A Coward." She actually receives a call from her contact there, but when she goes to the dead-drop, she is surprisingly attacked while in her car.

She may be the reason why Weller and Jane will see the contact at Sandstorm. Meanwhile, aside from that, the two will also meet face to face with an old enemy. But there is no official word yet on who exactly that enemy will be.

The last episode of "Blacklist" dealt with a removal business that was actually used as a front for human smuggling. The illegal immigrants are brought to a clinic, where their organs are harvested for some very wealthy clients. Weller, along with Roman, were captured by the enemies, but they were eventually rescued by the team. During that episode, Reade is also confronted by Patterson about his drug habits, which he vehemently denies.

The EconoTimes reports that actress Jaimie Alexander also opened up about Weller and Jane. Jaimie says that what's good about the two is that they get each other, which is crucial, especially with their line of work. The site also says that the team will find another mole, which may contribute to why Sandstorm has been one step ahead of them all this time.
