'Teen Wolf' season 6 episode 4 spoilers: Wild Hunt preys on lacrosse team; Lydia continues search for Stiles

The rules of the Wild Hunt are slowly coming to light as the sixth and final season of "Teen Wolf" unfolds. Now that Corey (Michael Johnston) has found a way to bring the Ghost Riders on an even playing field, will Scott's (Tyler Posey) pack finally be able to ward them away and retrieve the Wild Hunt's victims?

Corey's pivotal discovery did come with a catch, though. It has been said that anyone who catches sight of the Ghost Riders will have been marked for the Wild Hunt, and every single person at the party in Scott's house saw the Ghost Rider when Corey pulled it into existence. In "Teen Wolf" season 6 episode 4 titled "Relics," the Wild Hunt comes to collect its preys starting with the players of Beacon Hills High School's lacrosse team.

Will the combined forces of the alpha, Scott, and his beta, Liam (Dylan Sprayberry) be enough to keep their team safe? Or will the Ghost Riders come away from this particular hunt with the entire team in their loot bags?

Meanwhile, the episode preview features Lydia's (Holland Roden) continuing effort to find clues on Stiles' (Dylan O'Brien) existence. One scene shows her trying to peel off paint from a wall at the Stilinskis' house, but Claudia (Joey Honsa) stops her before she can uncover anything significant. She also comes to Sheriff Stilinski's (Linden Ashby) office to insist that people don't just get erased from existence without leaving something behind to remember them by.

The last three episodes have already proven this true. And although it was only Gwen (Alisha Boe) from the previous episode who specifically remembered her missing sister, this and the earlier relics all point to the possibility that Stiles and the others can still be brought back to the realm of the living before they are completely erased from existence.

Additionally, there is the matter with the new teacher, Mr. Douglas (Pete Ploszek) who was revealed to have been the tank guy escapee from the Dread Doctors' lair. He was shown in the finale episode of season 5. Reported to be a Nazi Alpha werewolf from World War II, the hot new teacher is also the mysterious monster that Chris (JR Bourne) is currently hunting. But is he really an enemy, or just someone who kills and preys on people's pineal glands out of necessity? Will he turn out to be the final supernatural foe that Scott puts down before he leaves Beacon Hills for college?

"Teen Wolf" season 6 episode 4 will air on Tuesday, Dec. 6, at 9 p.m. EST on MTV.
