TEXT: [PREVIOUSLY_ON] Derek: I know a little about this pack. Their Alpha is a woman named Satomi. They have a kind of secret meeting place in the woods. (GROANING) Deputy Parrish: Meredith's gone. They found her an hour ago in her room. Kira: Peter and Malia? Lydia: Father and daughter. Stiles: We should probably count it. (SNARLING) (SIGHS) (SNARLING CONTINUES) MAN ON TAPE: After entering the IP address, you will be connected through a Darknet portal to an untraceable bank. Once logged in, enter your account number to receive wire transfers. The IP address will deactivate with each transfer. You will be assigned a new IP address if you choose to continue down the list. Remember, visual confirmation is always required for payment. Stiles: You ever made a wire transfer? Scott: Never had enough money. Stiles: So you didn't understand a word of that either? Scott: I don't understand any of this. Why would someone use all this money just to kill us? Stiles: Someone wants you dead, dude. Badly. Whoa, whoa, what are you doing? Scott: It's late. We've got the PSATs in the morning. Stiles: No, I meant the money. $500,000. You know how much money that is? Scott: It's 500,000... Stiles: It's half a million dollars. Scott. What are you going to do, just slide it under your mattress? Scott: I have to talk to Derek. The money's his. Stiles: You mean his and Peter's. Scott: What does that mean? Stiles: It means maybe we should proceed with caution. Scott: You don't think we should tell Derek? Stiles: No. No. (SIGHS) No, of course we have to tell him. I'm just... I'm just saying, some of that money's Peter's, right? Scott: Yeah. Stiles: Right? Peter. Homicidal killer? Remember? You want to give $500,000 to him.
SUMMARY:
Derek rushes an injured Braeden to the hospital. A virus designed to kill werewolves is released during the PSATs, and the school is quarantined. Deaton is confronted by Satomi at the animal clinic; she explains that most of her pack have been wiped out by the virus, and she was the only one who was immune. After conducting an autopsy on a werewolf, Deaton figures out that the virus is a version of canine distemper . With help from Satomi and Derek, they realize that Reishi tea leaves are the cure, and that there is a jar of them in the Hale vault. Scott, Malia and Kira are dying due to the virus, and hide in the vault to avoid the assassin. Stiles discovers that an assassin, a teacher overseeing the PSATs, is responsible for unleashing the virus. Agent McCall saves Stiles by shooting the teacher, who was about to kill Stiles. Using the last of his strength, Scott finds the tea leaves and breaks the jar, releasing the spores, which cures the virus. Malia walks away from the others after discovering that she is Peter's daughter.
