In the previous episode, Scott and Theo's pack together rescued Lydia from Eichen House, thanks to Stiles and also Parrish, who saved the Banshee from her own screams. Fans did not miss that Stydia moment where Stiles says: "Lydia, please shut up and let me save your life."

With Lydia, Kira and Liam back in Scott's team, the upcoming episode will get back to the show's new mystery — finding out the identity of The Beast. Scott will use a charity lacrosse game to draw The Beast out.

Previously, showrunner Jeff Davis shared a few details about this new threat in Beacon Hills. "It's formed by shadows," Davis told Entertainment Weekly. "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."

"Figuring out who is The Beast is a major mystery of the season," Davis added.
