One of the executive producers of Pretty Little Liars recently revealed that fans will be seeing Jason DiLaurentis (Drew Van Acker) and Noel Kahn (Brant Daugherty) again.

Pretty Little Liars executive producer Joe Dougherty recently spoke with TVFanatic about what to expect when season 4B premieres in January, including the return of Jason and Noel.

"They're going to come in and move things forward," Dougherty said, noting that the fourth season is designed to be "a season of answers." He added that they are "really changing the game," starting with the first episode in January.

Noel has not been featured in season 4 because of his portrayer Daugherty taking a break to participate in season 17 of Dancing With the Stars. The actor came in seventh out of 123 participants overall.

One of the bigger questions going into the second half of season 4 is whether or not Ezra (Ian Harding) will become the big villain.

"I think what you see on most characters on the show is that they're usually motives behind motives and rationales behind rationales," he teased in reference to Ezra. "So that what you see is true and we're not going to take anything back but the story, there is a complete story that's told and you're just seeing fragments of it now."
