The season 11 finale of Fox's Bones will be a meaningful one to longtime fans of the show.

The finale, titled "The Nightmare Within the Nightmare", is set to feature the return of the Puppeteer serial killer and promises to be a tense one for many characters.

Bones executive producer Jonathan Collier spoke about this in a new interview with E! News, explaining how the finale actually has a connection with the show's very first season.

"We are going to be seeing a type of serial killer we've never dealt with before, in a way that really is going to put some of our characters we love into direct jeopardy and conflict with each other," he said. "We will be paying it off with an amazing twist that we're really gratified by that's going to leave a lot more to come for the next season."

The new villain will be the primary antagonist for the show's 12th and final season, as Collier teased.

"We're going to bring in a new threat, a new villain, who couldn't have existed if the first season hadn't existed. We're really going to go back to our roots," Collier said. "I guarantee that no one will guess who it is still, but it all makes sense and I'm so happy to be dealing with this. I'm so happy to be laying this out and plotting it and it really carries us to an exciting and impactful place."

Luckily, Collier did admit that there won't be much turmoil in the Brennan (Emily Deschanel) and Booth (David Boreanaz) relationship.

"I think we've done a lot of challenging their relationship and their marriage, and that's not what this season's about. Their love, their marriage is strong," Collier revealed.

The Bones season 11 finale airs Thursday at 8 p.m. ET/PT on Fox. The show's final season will come along at some point in 2017, though a specific premiere date has not yet been determined.
