[Kira has just woken Scott up from a nap in his bed, and when he opens his eyes, he is surprised to see Liam and Mason standing in front of them]
Scott
What's wrong?
I found something out from Corey. We know what Theo's doing.
He's looking for an Alpha. A blind Alpha.
Scott
[shocked] Deucalion.
[Scott and Stiles have just found Deputy Strauss in the hallway of the high school with a huge shotgun in his hands]
You don't think this is a bit much in terms of firepower for a high school?
SStrauss
Your dad's the one that issued us these things, and he wouldn't officially say why.
Scott
Did he say anything unofficially?
SStrauss
No, but everyone's got a theory.
SStrauss
[nervously] I shouldn't be talking to you guys. Don't you have class?
Come on, Strauss! What's your theory?
SStrauss
[hesitates] Do you guys believe in the supernatural?
[Stiles and Scott give each other alarmed looks]
I was just trying to do something right.
Scott
You do a lot right.
Yeah, but I did one thing really wrong.
Scott
Hayden's alive. Everything before that doesn't matter.
It should. I feel like I have to do more than just say sorry.
Scott
[amused] Actually... you still haven't done that.
[sighs] Back at my old school, at Devenford... I got into a fight with this kid. I knocked two of his teeth out. They made me write a letter of apology. We both knew it meant nothing. We both knew that sooner or later, we're gonna get into another fight. I can't just say I'm sorry. I feel like I have to do something. Like, maybe... somehow... I have to save your life.
Scott
[smiles] Don't worry. I'm pretty sure you'll get a chance.
[Scott and Liam have just found Argent hiding in the Dread Doctors' laboratory. Scott senses Gerard's presence and gives Argent a hilariously disappointed look]
Scott
You didn't.
[Scott's eyes flare red as Gerard approaches him, and Gerard looks genuinely surprised]
I haven't seen that color on you. It suits you.
[to Scott] Who's the old guy?
[laughs] Uh, at the moment, they would call me a necessary evil. But you can call me Gerard.
Scott
[to Argent] What were you thinking?
He's right. If you want to catch a werewolf like the Beast of Gévaudan, you're going to need more than one Argent.
[sighs] He knows all the stories. All the folklore. Everything written, and everything passed down.
[Argent and Gerard have just showed Scott and Liam the fresco painting with the two beast-like creatures fighting each other]
The one on the right is the Beast of Gévaudan.
Scott
Do you know what the other one is?
The Hellhound. The guardian of supernatural places. They're both creatures of the night. But you may know them as ordinary creatures during the day. And, most likely, neither of them know what they are.
[Deaton, Stiles, and Scott are at the animal clinic, where Deaton has just pulled out a stack of old Polaroid photos, all of which depict various supernatural creatures with bloody holes drilled into their heads]
What I'm about to show you isn't supposed to exist. This is the only surviving evidence of Dr. Valack's time as Chief Medical Officer at Eichen House. To call it human experimentation would be... charitable.
[Stiles' eyes widen at a photo of a woman who is painfully covering her ears with her hands]
A Banshee. She died screaming.
So, he drilled holes into their heads? All of them?
That was the experimentation part. He did it to werewolves, Banshees, wendigos... any creature he could get his hands on. And Valack found that trephination would initially heighten their powers, but to levels that couldn't be contained.
Scott
So, he wants to make Lydia more powerful.
Yeah, except she's going to end up like them.
Worse, actually. Lydia's abilities were already pretty exceptional to begin with. Putting a hole in her head will be like causing a leak in a nuclear reactor. She'll hear everything-- every death, every dying scream, all at once.
Scott
[worriedly] That's gonna kill her.
Not only that... Her own dying scream could be so powerful that it might kill everyone around her.
[Scott, Stiles, Kira, Malia, and Liam are gathered in the McCall House kitchen, where they're outlining their rescue plan]
There's four steps-- we get into Eichen, we get into the closed unit, we get Lydia, and get out.
Scott
And, we have to do all of this while getting past orderlies, guards, electric door locks, and a mountain ash barrier.
[skeptically] You have a plan for all of that?
[Stiles holds up an RFID keycard]
I stole this last night off an orderly... But, it's useless, 'cause they reset the codes each night.
Scott
The only way to get Lydia out of Eichen is to make that keycard work again.
How are you gonna do that?
We're getting to that, okay? Just listen. Two weeks ago, there was a brownout, and the security system rebooted. During a reboot, all of the keycards revert back to a default code.
So, if we trigger a reboot, the card goes back to the default code, it works again!
How are we gonna cause a brownout?
Scott
That's your part.You're going to draw power from the main line, but only enough to cause the brownout.
Not a blackout-- you do that, and you send Eichen into lockdown, which would be bad. Very, very bad. There's an electrical room behind the reception counter. The main power line goes into two breakers that run power to all of Eichen.
[panicked] Okay, slight problem-- I don't know how to do that.
Scott
That's okay! You have time to practice.
And, when we're gone, all anyone's going to think is that there was a reboot of the system caused by a brownout. Uh, any questions?
How do we get into Eichen House in the first place?
What's our worst-case scenario?
[overwhelmed] Okay, admittedly, a lot could go wrong...
[exasperatedly] Everything could go wrong.
Scott
[sighs] Guys, if we don't do this, we lose Lydia. She's going to die in there tonight... and she might take a lot of innocent people with her.
[Stiles and Scott have just run into Theo in the library and are both scowling at him]
Scott
What are you doing here?
I still need to graduate.
No. No, what you need is to be beaten, severely, with a lead pipe wrapped in barbed wire...
[sighs] Okay, I admit that mistakes were made--
Murders! Murders were made!
You know how the Soviets helped us win World War II? They knew how to make it through a Russian winter.
[sarcastically] That it? Okay. Thank you, Theo. Very informative.
