How will the Stefan/Silas doppelganger situation play out in season five of "The Vampire Diaries"? CW/The Vampire Diaries

Fans of “The Vampire Diaries” are still in shock after the jaw-dropping season-four finale, and it sounds like season five is going to be just as action-packed. The new season won’t premiere for a couple of months, but, meanwhile, we’ve got a line on what to expect from the Silas/Stefan drama.

The season-four episode 23, “Graduation,” revealed that Stefan is a doppelganger of Silas. Like Katherine, Silas has some serious issues with Stefan -- and chose to lock him in a box and throw him over a waterfall into a lake. So, how will season five play out with Silas impersonating the younger Salvatore? According to executive producer Julie Plec, the Mystic Falls group will catch on pretty quickly.

“Truth be told, I don’t think it’ll be too long,” Plec told TV Guide. “I think that there’s more fun to be played with people learning quickly, but independently of the other, so there’s a lot of good bait-and-switch Katherine-style stuff that could happen early in the season. And people that know Stefan well will be able to catch on pretty quickly I would hope.”

While Silas and Stefan have obvious different personalities, fans can’t forget that Silas has the ability to read minds. An action by Silas might tip off Damon, Caroline or Elena, but the original bad guy has the ability of flipping the Stefan switch to throw them off again.

But does Silas actually want to stick around Mystic Falls to wreak havoc on the crew? With the cure gone, his path toward death has definitely changed.

“His agenda has always been to cure himself, to get rid of the other side, so that he could then die and pass over and find peace,” Plec told TVLine. “That will remain his agenda.”

The mystery is exactly how Silas will get to the other side with the veil up and Bonnie gone. Is another Bennett witch hanging around town? Or will Silas (or someone else) try to resurrect her?

Fans already know that Bonnie will be sticking around in season five, but we don’t know to what extent. In the season-four finale, Bonnie made Jeremy promise to keep her ghostly secret for the summer, but will little Gilbert be able to keep that promise? Or will he spend his summer trying to find a way to bring her back?

Without magic on the other side, Bonnie is pretty useless, but having Jeremy be able to see her can definitely work in her favor. While there do not appear to be any witches left in Mystic Falls to help, it’s possible that Silas may have some other mysterious powers up his sleeve.
