"Teen Wolf" season 5 episode 17, "A Credible Threat," will see the pack try to intervene with a lacrosse game in order to save hundreds of people, identify the Beast, and stop the Dread Doctors' plans.

During the last episode Scott (Tyler Posey) and the rest of the pack rescued Lydia (Holland Roden) but not before discovering that Dr. Valack (Steven Brand) kidnapped her in order to retrieve more information about the Beast. The pack wants the same goals but they'll be getting it in a different way.

The promotional trailer for the episode showcases that the Dread Doctors and the Beast will be present during a lacrosse game between Beacon Hills High School and Devenford Prep, which will occur during a full moon. It is stated in the trailer that the Dread Doctors are not afraid of the full moon and that their goal is to make the Beast stronger.

Of course this means the Beast may end up wreaking havoc at the game and the pack will try to get the game cancelled before anything violent takes place. Unfortunately, the only person who can cancel the game is Coach Finstock (Orny Adams), who makes his return after not appearing throughout season 5A.

Since this is a lacrosse game, the episode will also see the return of Brett (Cody Saintgnue). Brett will be willing to help Scott and his team save the people at the game but it does not necessarily mean Brett will be leaving his group to join Scott's pack.

"If it seemed right, if it seemed like the right move, if it seemed like the best integrity thing to do, I think Brett would do it. But do I think he would just leave the pack just to join like a pack that's 'stronger' or something? I don't think so," actor Cody Saintgnue told the IB Times last December.

"Teen Wolf" season 5 episode 17 airs this Feb. 16.
