Teen Wolf's Stiles will need to keep a lid on his dark side if he wants to keep Void Stiles from slipping out in season 5B.

The Nogitsune is gone and, as much as we hate to agree with Theo on anything, the chimera is probably right when he says it's not coming back. These days, however, Stiles' anger is boiling just under the surface.

According to series creator Jeff Davis, the return of Void Stiles will never be off the table.

"That's part of the darkness still lurking inside of Stiles and he'll have the fear that, is it more than just being possessed?" Davis explained to Entertainment Weekly. "Is there something inside that he has to keep a lid on?"

Luckily, Stiles will soon have Scott to look after him once more. Theo's antics threw a wrench in their relationship (literally), but time will eventually bring Beacon Hills' dream team back together.

"It's going to be rocky still," Davis teased. "They were both taken in by an Iago and Theo played them all and pitted them against each other, so they've got to get past the underlying resentment and forgive each other and it's going to take more than one episode."

Well, that's certainly a bright spot on the horizon. With all the darkness swirling around Beacon Hills, viewers certainly need something to look forward to.
