Teen Wolf season 4, episode 7, “Weaponized,” has just finished airing. Our recap explains everything that went down in Beacon Hills this week.

Teen Wolf season 4, episode 7, titled “Weaponized,” begins with a man who has an injured werewolf trapped in a circle of mountain ash. Meanwhile, Scott and Stiles listen to a tape from the Benefactor and discuss what to do with the $500,000 of which they are now in possession. Stiles doesn’t want to give Peter his money, but before they decide anything, Malia shows up and tells them Satomi’s pack is dead.

Derek takes Braeden to the hospital, saying she’s been shot, while Satomi shows up at Deaton’s and attacks him. But, you know, as a friend.

Back at the school, we see that the person in charge of the PSAT is the mysterious man from earlier. Coach is supposed to be helping Mrs. Martin oversee the test, but he hasn’t shown up. She finds him slumped over his desk, and at first she thinks he’s broken his 15 years of sobriety — and at school, no less.

But after a girl passes out during the PSAT, Mrs. Martin notices a rash on her arm and goes back to check out Coach. He has the same thing on his back. Mrs. Martin calls the CDC, who show up and quarantine the school.

At Deaton’s office, Satomi brings a member of her pack who is blind and having trouble controlling his transformation. At the hospital, Braeden tells Melissa and Derek that Satomi’s pack wasn’t poisoned, they were infected by a virus designed to kill werewolves.

Lydia was one of the smart ones this episode, as she’s not at school experiencing all the excitement. Instead, she’s with Meredith’s contents at the lake house. She tries talking to Meredith’s spirit, but doesn’t get an answer. Instead she apologizes to her and then packs up the contents of the box. Before she does, however, she notices a picture of Meredith in the lake house — her lake house.

At the school, one of the CDC workers tries to draw blood from Kira, but she accidentally zaps the woman instead. The group takes cover with Mr. Yukimura, who notices that they’re all sick in one way or another. The gang decides to hide in the vault, which they find a secret entrance to in the basement.

Stiles and Scott trick Malia into opening the vault door, since she’s a Hale, but Malia says she wants to know what they’ve been hiding from her before she opens the door. Just before they’re about to tell her, Malia breaks the awkward silence. She knows she’s on the list. Stiles and Scott sigh in relief. Malia’s just happy she isn’t worth as much as everyone else, which means the assassins will take out others before her.

In the vault, Stiles speaks up about his money woes, saying the Hale fortune would solve a lot of problems. They talk about how rare it is that bearer bonds even exist still, and we have to wonder if that could help them track down the Benefactor, who had to change the bonds into cash.

They’ve also got another problem on their plate. Scott wants to tell Malia about her father — her real father — but Stiles is afraid it’ll make her run. He’s also afraid what Peter will do to her once she confronts him, saying that Peter will manipulate her, just like he manipulates the rest of them.

They decide Stiles has to leave in order to keep everyone safe and because he won’t be affected like the werewolves will. Deaton cracks open Satomi’s pack member’s skull (don’t worry, he’s dead) and figures out that they’re dealing with canine distemper that’s been weaponized.

Stiles figures out Coach is the only adult who had been infected, so he begins searching his office. Meanwhile, Satomi reveals that she’s a longtime friend of Derek’s mother, and during their conversation Deaton figures out that Satomi’s love of reishi tea kept her from getting infected.

It’s possible they’ve discovered the cure, but in order to get the rare tea, they have to go into the Hale family vault. In the vault, however, the symptoms for our heroes are getting worse, and Malia has gone blind. She’ll only have a few minutes now.

Miraculously, all of the non-supernatural creatures suddenly get better. But everyone in the vault is getting much, much worse. As the man from the PSATs holds a gun to Stiles’ head, Stiles refuses to give up the location of his friends. Before the man can pull the trigger, Agent McCall shoots him in the head, and then gives Stiles a message from Melissa: the antidote is in the vault.

Scott barely gets to the tea in time, but he finds the strength to pull it from the shelf and break it open, breathing in the cure.

Unfortunately, as Scott, Kira, and Malia get better, that means Malia’s eyesight returns. She sees her name as Malia Hale on the Dead Pool and walks out on Stiles.
