"Grimm" Season 5 will see the arrival of a new big bad in town, David Giuntoli revealed during an interview with Parade.com.

"One of the things that keeps our society together is the fact that these monsters aren't going berserk all the time. They are trying to hold it together," Giuntoli, who plays the role of Nick Burkhardt, said.

While such is the case in the previous seasons of "Grimm," this is about to change this season, as this new big bad will try to take over the world without trying to blend in with humans. The actor also revealed that aside from trying to deal with the arrival of a new big bad in town, he will also have to face his own challenges of being a father.

"My priority is I want to keep this baby safe. And the best way to do that is to pack up and leave. Get the hell out of Dodge," he added.

Giuntoli went on and addressed rumors that Juliette is still alive because her body has not yet been found. The actor said that while he does not have any idea about the writers' plans and whether or not Juliette (Bitsie Tulloch) is still alive, he insisted that the show has gone for 11 episodes without Juliette.

Meanwhile, the official synopsis for "Grimm" Season 5 Episode 3 titled "Lost Boys" has been released. According to Carter Matt, the upcoming episode will show Nick and Hank "race against the clock," as Rosalee goes missing. Will they be able to save her just in time?
