Teen Wolf finale recap
Scott (Tyler Posey) learned who his enemies were in the "Teen Wolf" Season 5A finale, and it's a revelation that will majorly affect Season 5B. MTV

“Teen Wolf” Season 5B is about to jump back into action, but fans will want to remember where it left off. The MTV drama is pretty complicated, and it isn’t the easiest thing to jump into without recalling the last episode. Here’s what you definitely need to know before tuning in to Tuesday's midseason premiere:

Scott vs. Liam –The Dread Doctors’ experiment was killing Hayden (Victoria Moroles), and Liam (Dylan Sprayberry) thought a werewolf bite might be the answer. Scott (Tyler Posey) refused because he didn’t think she’d survive the bite, and a supermoon only increased Liam’s anger. Theo (Cody Christian) locked Liam in the school with Scott via mountain ash. The alpha and beta engaged in an epic fight, but Mason (Khylin Rhambo) interrupted to tell Liam that Hayden died. It was enough to make Liam realize what he is doing and back off.

Theo Is Evil – Theo finally revealed that he is evil and a chimera. He is part coyote, which is why Malia (Shelley Hennig) trusted him to help kill the Desert Wolf. However, Scott knows better. He realized that Theo poisoned his inhaler with wolfsbane. The villain was also banking on Liam killing Scott. Once the beta bailed, Theo decided to attack the alpha himself. He dug his claws into Scott’s chest and seemingly killed him. His mother arrived, and Mason said that he hasn't had a pulse for 15 minutes. That didn’t stop Melissa from doing CPR. The distressed nurse hit his chest one last time and he came back to life.

Parrish Is A Hellhound – Lydia (Holland Roden) finally figured out what Parrish (Ryan Kelley) is. She did some research and discovered that the deputy fits the description of the hellhound. He is considered a guardian of the supernatural. Unfortunately, that didn’t stop his recent habit of snatching bodies. His powers seemed to take over and he stole the bodies that didn’t survive the chimera experiments and brought them to the nemeton.

Stiles’ Choice – Theo gave Stiles a horrible ultimatum. He could either go to Scott to share new information or save his father, who Theo kidnapped and assaulted. Stiles chooses the Sheriff, who was found badly beaten.

Theo’s New Pack – Theo put his claws into Lydia’s neck to learn the nemeton's location. After the experience, Lydia seemed catatonic. When he arrived at the nemeton, Theo injected all of the dead chimeras with some concoction that brought them all back to life. It seems none of the Dread Doctors’ experiments, including Hayden, are actually dead. They’re Theo’s new pack.

In “Teen Wolf” Season 5B, Scott will be focused on bringing the pack back together. He and Stiles will have to find a way to make up fast because Theo did more than just beat up the Sheriff. Something mysterious is wrong with him. Meanwhile, Liam will discover that Hayden isn’t dead anymore, but that doesn’t mean they’ll be getting back together. They’re in opposing packs. However, both packs might have to worry about the same villain. The Beast of Gévaudan is not going to make anything easy for the group.

“Teen Wolf” Season 5B premieres Tuesday at 10 p.m. EST on MTV.
