MTV’s scary supernatural drama “Teen Wolf” is back, and according to series developer Jeff Davis, no one will be safe.

Speaking with E! News, the 40-year-old writer/producer who was the brains behind the hit show "Criminal Minds," said, "I think fans should be worried about everyone. Fans should be worried about the pack and whether or not they can survive this season."

In the season’s unnerving premiere episode, titled “Creature of the Night,” fans witnessed Lydia (Holland Roden) trying to escape from Eichen House while being thwarted by a hallucination of Aiden (Max Carver).

According to Davis, that is just the start of her troubles.

"I would be worried about Lydia, definitely. She ends up in a very bad place by the end of the season," he says, adding: "What Lydia realizes this season is that she's not quite the fighter that her friends are and she gets tired of it and she wants to learn how to fight and protect herself, and that leads her to a path whether she wants to master her power and learn new powers as well. She's going to learn it from different sources, different skills from different sources."

Things sound like they will be changing up for Malia Tate (Shelley Hennig) as well. Describing what her character has gone through to Zap2it, actress Shelly Hennig says that "Malia has basically gone through school with the pack by her side. That's been fun to see. She's still not totally finished, if you will, but I like the pack has accepted her."

"The challenges I have had with playing Malia this season is that she's going through emotions we've never seen her go through before -- a lot of them are very human," says the 28-year-old former “Days of Our Lives” star.

The next episode of “Teen Wolf,” titled "Parasomnia," airs next Monday at 9 p.m. on MTV.
