Actress Arden Cho will return as Kira Yukimura in this Tuesday's episode of Teen Wolf. Executive producer Jeff Davis confirmed to TV Line that Scott and Kira are "still together". Davis called the couple's time apart as an "anxious separation" and teased that Scott is still "very worried about" their time out.

"When we pick up with Kira, you'll see just where Mexico has taken her to try to fix the problem of the fox spirit taking over," the creator revealed.

Entertainment Weekly has released the exclusive look of the show's newest villain, as showrunner Jeff Davis also shared a few details about The Beast to the magazine.

Davis told EW: "It's formed by shadows. The chimera that's inside it is sort of surrounded by it. The person — we don't know whether it's a he or she yet — doesn't necessarily transform like Bruce Banner transforms into the Hulk. It's actually more just shadows and darkness take shape around that person."

The showrunner also added that figuring out who is The Beast is a major mystery for the rest of the season.
