Thanks to the mysterious Benefactor, every supernatural creature in Beacon Hills is a walking target. Although some members of Scott's (Tyler Posey) pack are human, Dylan O'Brien (Stiles) recently warned fans that one should never assume their favorite characters are safe.

"Yeah, fans can always kind of be wary of that," O'Brien said in reference to sudden deaths, according to Hollywood Life. "That's sort of something that's always a possibility on our show. It makes it exciting. It makes it devastating."

Some viewers are still reeling from Alison's (Crystal Reed) death in season 3B,  but they should start preparing themselves for another wild twist and potentially deadly finale.

"The second half of the season, fans will finally get to see who The Benefactor is - the bad guy basically of the season," O'Brien explained to Hollywood Life. "That will be revealed and then it always sort of finds a way to get flipped on its head and it's like not what you think. That's always all kinds of fun and it leads into this crazy finale where basically everybody's life is on the line."
