Jaws dropped with the latest trailer for "Orphan Black" season 4, just hours before the premiere episode airs on BBC America.

The latest trailer shows Paul Dierden (Dylan Bruce) and his girlfriend Beth (Tatiana Maslany), two of the supposedly dead characters of the show, having an intense and possibly fatal conversation with each other.

This could prove earlier spoilers' claims that "Orphan Black" season 4 will feature a lot of flashbacks, since that will be the only logical explanation why the two dead characters are included in the premiere episode of the new season.

In an interview with Entertainment Weekly, actor Jordan Gavaris confirmed that season 4 will start with a lot of references of season 1.

"It adds a sense of paranoia to the season, which I think the first season had a lot of, but then as the mystery unfolds and you learn who these people are the paranoia tends to quiet a little, because it's really loud normally," the actor explained. "But we have that back this season and it just adds to the hair trigger mystery effect."

Gavaris also mentioned that his character, Felix, will face more struggles in dealing with the fact that his foster sister, Sarah Manning (Maslany), is intensifying her quest to find out more about the backstory of the Leda project and her clones this season, which could make him feel alienated a little bit.

According to the actor, Felix and Sarah's bond was formed because of their similarity as orphans. But when Sarah learned that she is connected to several other individuals through clones, Felix will feel a little left out of his sister's life.

"I think he's just grappling with where he fits in, where his place is in the family, and I think it might mean he gets to explore new relationships. I can't necessarily say with whom," the actor revealed.

"Orphan Black" season 4 premieres on BBC One on Wednesday, April 14.
