Eichorst (Richard Sammel) and Dutch (Ruta Gedmintas) had fans of FX's "The Strain" on the edge of their seats in episode 11, "Dead End." After several borderline disturbing moments, Dutch was able to rescued before Eichorst ate her as a vampire snack.

After their tense encounter in "Dead End," Sammel and Gedmintas spoke to the International Business Times over a press call about what to expect with the final two episodes of Season 2, and the shows use of flashbacks. Two episodes remain in "The Strain" Season 2 and Sammel and Gedmintas said there will not be a shortage of conflict or intensity.

"The whole bow of the second season is a condensation of conflict. There is more and more reason to believe the humans will make it and there are more and more reasons to believe the vampires will make it. There is preparation for a big battle, which we have seen with Red Hook, but there is something bigger coming up," Sammel said.

"I think the finale is one of the most ambitious episodes, I remember our producer looking slightly crazed the last few weeks of filming just feeling the weight of the pressure of what the script had delivered to him," Gedmintas dished. "There's definitely going to be a big finale."   

Throughout both seasons of "The Strain," many of the main characters have had their backstories explained in a series of flashbacks. Each backstory shows the viewer the history of how long the conflict between strigoi and humans have been going on, as well as what turned the characters into the ones we see on screen.

Setrakian's (David Bradley) heartbreaking story was told throughout Season 1, including the fact that the Master took away the woman he loved. Flashbacks in Season 1 also showed that Eichorst was a Nazi officer, who had Setrakian build the Master's coffin while in a concentration camp. Season 2 dug a little deeper into the Eichorst character and showed he wasn't always such an evil villain.

In episode 11 it was revealed that Eichorst was once an unsuccessful radio salesman, who had no direction in life. He was kind, but was never respected and felt he didn't have a purpose. After hearing a pitch from a Nazi soldier, Eichorst found his calling and would forever be changed by it.

"When you have a show that's this intense on action and gore, you need to have a sort of respect for the intimacy of the characters and you need to understand them, who these people were before this catastrophic event because everybody responds differently once something huge in their life happens," Gedmintas said. "You have to see who they were beforehand to understand why each of them take on a different role, that's what's interesting in humanity, why we do things."

Sammel said the flashbacks give depth to the characters, whether it's Quinlan (Rupert Penry-Jones), Eichorst, Palmer (Jonathan Hyde) or the Master, and it allows the viewer to understand why everything is happening and why characters are who they are. 

"It's a genius idea because it goes way beyond the life span of a human being, so we can travel far back and if we use it wisely you will not get bored of it," Sammel said.

Catch Sammel and Gedmintas Sunday at 10 p.m. EDT on "The Strain" on FX. The Season 2 finale airs on Sunday, Oct. 4.
