Not everyone is in control of their powers on “Teen Wolf” Season 5B. In episode 17, the gang learned more about how the Beast of Gévaudan gains power. However, the pack seems to be in less control of their own abilities. Both Kira (Arden Cho) and Parrish (Ryan Kelley) learned that their supernatural gifts are out of their control. However, one of them may have been able to fix the problem.

Parrish explains that he finds burned clothes and blood every time he wakes up. He needs Chris Argent (J.R. Bourne) to follow him to figure out what he’s doing. Parrish has no idea if he is killing people, but if he is, he needs Chris to stop him.

Scott (Tyler Posey), Stiles (Dylan O’Brien) and Liam (Dylan Sprayberry) are in touch with Chris and they follow Parrish too. When Argent gets to the school, there are already banners that have been burned. He meets up with the students and says that he lost the hellhound.

Suddenly, they discover a school bus full of dead and seriously injured teenagers. A student reaches out and asks for help, but Parrish appears and says that it’s a trap. The Beast steps onto the bus and rips the student in half. It’s not a trap for Scott. The creature wants Parrish. The Beast leads the hellhound into the woods, but the boys know better than to follow them.

Scott doesn’t go home because apparently Melissa (Melissa Ponzio) is cool with her son spending the night with his girlfriend. It seems curfews are less restrictive when you regularly save the city. When Scott wakes up in his girlfriend’s bed, he doesn’t let Kira know that he sees her practicing her kitsune moves. However, he looks suspicious.

At school, Corey (Michael Johnston) tells Mason (Khylin Rhambo) that he wants to ditch town. He is covered in burns from the run in with Parrish at Eichen House. Mason claims that he needs Corey around, but Corey knows that isn’t true. Mason says the pack always has a plan, but he is the one who has a major discovery.

Mason realizes that the Beast always shows up near a huge transmission source, like a cell tower. The Dread Doctors could use the news vans from the upcoming charity lacrosse game to bring the Beast out. The plan makes sense, especially since Scott thinks the Doctors want the Beast to come out more often. He might be gaining more power with each transformation.

Scott wants to get the lacrosse game canceled. The Sheriff (Linden Ashby) can’t cancel the game without a credible threat. He tells Stiles to get their coach. Their substitute doesn’t do much, so it's time to get Coach Finstock (Orny Adams) out of rehab. Finstock has been living the good life for the last seven months in rehab, but the boys promise he won’t have to coach anything. They just need him to forfeit.

Meanwhile, Lydia (Holland Roden) has to help Parrish. She finds the deputy bleeding in the stacks at the library. She brings him to the Chris and Gerard Argent (Michael Hogan), who have an idea.

They want to put the deputy in a freezing machine. It’ll bring Parrish’s body temperature down, which could bring out the hellhound. They want the hellhound to evolve to keep up with the Beast. They explain that the Beast is remembering its old life. Eventually, the Beast will remember his or her true identity. The consciousness of the teenage chimera won’t be there anymore. Parrish goes into the freezer and hopes for the best.

Back at school, the pack is nervous when they get to the game, but they have to go through with everything. Malia (Shelley Hennig) will take out the TV vans, but everything should be fine once the game is forfeited. “No one’s dying tonight,” Scott says.

When they get on the field, Finstock says he has never forfeited a game. They better hope Malia can pull all the wires in time. She can’t destroy all the transmission systems in the news vans because her mother (Marisol Nichols) interrupts. The Desert Wolf pulls her down and attacks. Malia knows that her mother can’t steal her powers until there is a full moon. The assassin offers to work together to work something out. Malia promises to kill her mother instead.

They have more trouble on the field when Kira’s kitsune powers come out. Scott tries to calm her, but Kira tells him to get out of his way. They have Brett (Cody Saintgnue) knock her down. Kira gets kicked off the field and starts muttering in Japanese.

Brett’s sister follows her. She tries to stop Kira and even speaks to her in Japanese. However, Kira viciously attacks her. Kira brawls with Brett’s sister through the school. Eventually, Scott comes into the school and has to hold back his girlfriend. Her kitsune powers go into full fire mode, but Scott finally brings her back to her senses. When Kira’s powers calm down, she has no idea what she’s done.

Meanwhile, Mason and Corey try to see if any of the Devenford Prep players have a shoe that matches the imprint the Beast left behind at the hospital. They don’t find what they’re looking for, but they share a kiss while snooping. Unfortunately, it seems like something is wrong with Corey. They decide that they need to leave quickly.

Back on the field, Hayden (Victoria Moroles) decides that she is no longer in the chimera pack. “I’m with you, all of you.” Hayden tells Liam. She realizes that she wants to be with Liam no matter what happens next. Liam has a game to get to though. They need more time on the field so that Malia can take out the news vans. Her mother is distracting her, but Liam’s girlfriend may have given him the confidence he needs. He suddenly displays some impressive skills and buys some more game time by evening up the score.

Lydia is the only pack member absent from the game because she is helping Parrish. She tries to talk to him after the freezer is on, but he says that he isn’t the deputy. “Jordan Parrish died. There is no Jordan Parrish,” the hellhound says.

The hellhound explains that Parrish is simply a body. Lydia says that the hellhound needs Parrish. He has to hold onto the human that will help him defeat the Beast. She tells him to remember Parrish’s death. It was when an IED exploded while Parrish was in Afghanistan. Parrish falls out of the freezing chamber, suddenly feeling like himself. He says he knows what to do.

That’s good news because the Beast is about to attack again. The Desert Wolf knows Malia feels affection for Stiles, and somehow that’s enough information for the villain to back off. That’s concerning, but Malia has to focus on the task at hand. She disables the last of the news vans, but the first van already fixed their transmission system. They can’t stop the signal that brings the Beast out.

Liam confronts the Beast head on, but the creature is chasing people down the halls of the school seconds later. The beta clearly didn’t win that fight, but fans will have to wait until next week to see if he survives.

“Teen Wolf” Season 5B airs Tuesdays at 9 p.m. EST on MTV.
