Previously on "Teen Wolf..."
Derek, I can't take it anymore.
Sacrificial blood. We're in a Nemeton.
- What's happening to me? - I don't know.
Why don't you just come back with me?
You, Lydia, you're just a girl who knew too much.
If a Druid went down the wrong path, there's a Gaelic word for that as well, Darach.
Dad?
Okay, all medications should be sealed inside the plastic bags,
and the patients carry it in their hands.
When you've completely evacuated the room,
you mark the door with a red "X," okay?
What the hell is going on?
The weather called for mild thunderstorms this morning.
And now they're saying power is already out in several towns.
Hill Valley's under a flood watch.
I live in Hill Valley.
Are your patients clear?
Uh,
all except for Cora Hale.
Hey, anyone want to tell me when they're getting my niece out of here?
Sorry, but she wasn't, uh...
You're supposed to be dead.
I get that a lot actually.
Derek?
- Derek, where are you? - Right here.
Thank God.
Something happened at the recital. At the school.
Okay, I need to tell you before you hear it,
before you hear any of it from them.
- From who? - Scott, Stiles.
They're gonna tell you things.
Things you can't believe. You have to trust me, okay?
- You trust me. - What is it?
Promise you'll listen to me.
I promise.
They're already here, aren't they?
So, they told you it was me?
That I'm the one taking people?
We told him you're the one killing people.
Oh, that's right.
Committing human sacrifices? What, cutting their throats?
Yeah, I probably do it on my lunch hour.
That way, I can get back to teaching high school English
the rest of the day.
That makes perfect sense.
Where's my dad?
How should I know?
Derek, tell me you don't believe this.
Do you know what happened to Stiles's father?
No.
Ask her why she almost killed Lydia.
Lydia Martin?
- I don't know anything about that. - What do you know?
I know that these boys, for whatever misguided reason,
are filling your head with an absurd story.
And one they can't prove, by the way.
What if we can?
What is that?
My boss told me it's a poison and a cure,
which means you can use it
and it can be used against you.
Mistletoe?
Derek, wait, wait!
You need me.
What are you?
The only person who can save your sister.
Call Peter. Call him!
It's not good. She's in and out of consciousness.
She's vomiting up black blood along with one other alarming substance.
Mistletoe.
How did you know that?
Derek. Derek, what are you doing?
Her life, it's in my hands!
Stop. Derek, stop!
Stilinski, you'll never find him.
Derek.
Derek!
That's right.
You need me.
All of you.
You should know I'm not doing this because I have to.
I want to.
I could still run,
and you wouldn't have an easy time stopping me.
But I don't want your sister to die.
I'm only doing what I had to do.
Shut up.
You need to hear the whole story, Derek.
You need to know just how connected we really are.
Stop talking.
I don't know, something feels wrong about this.
You know, we proved it to Derek,
but she still had this look like it didn't matter.
You know, like it was all still going according to plan.
You saw it, didn't you?
What's that?
Well, you got claws. I got a bat.
Scott! Scott!
What are you doing here? The hospital's evacuating.
- We're here for Cora. - What, all of you?
Why does Stiles have my bat?
Mom, just trust me on this. You need to get out of here.
Right now.
The building is supposed to be clear in 30 minutes.
We've got two ambulances that are coming back.
One's 10 minutes out, the other's 20.
Cora needs to be on one of those.
They'll be picking up in the basement garage.
- Got it. - Okay.
You don't have to keep me on a leash, Derek. I'm going to help.
Derek.
We got a problem.
Big problem.
Help me.
Ethan, Aiden, stop!
You don't know what you're doing.
All we want is her.
Okay, everybody, let's evacuate this way and stay calm!
You guys good?
Good... Oh! Oh, I'm so sorry.
Don't stop, don't stop!
Stiles!
I can't get a hold of Derek or Scott. How's Lydia?
She's got bruising on her neck.
They're taking her to a hospital downtown
because Beacon Memorial is being evacuated.
- The storm's that bad? - It will be.
And I overheard an EMT saying the backup generators
might be too old to last if the power goes out.
Beacon Memorial.
- That's where Cora is, right? - I'm taking the two of you home.
No, I have to get to the hospital. I can't leave Cora there with just Peter.
Isaac.
I'll drive.
Thank you, Ms. McCall.
You're him, aren't you?
Him?
The bad guy.
You have no idea.
You hesitated.
I pulled back. There's a difference.
They're protecting her.
- They don't have a choice! - Neither do we!
If all these sacrifices, all these bodies piling up,
if it's actually giving her the power to get rid of us,
then we need to take any chance we can to get rid of her.
- Where's the big guy? - He's close.
What about Ms. Blake?
What do you mean? What does that mean? Like, she's gone?
- Scott, are you kidding me? - Shh, quiet.
Me be quiet? Me, huh? Are you telling me what to do now?
When your psychotic, mass murdering girlfriend,
the second one you've dated, by the way, has got my dad
somewhere, tied up, waiting to be ritually sacrificed?
Stiles, they're still out there.
And... And they want her, right?
Which means now we don't have her either,
so my dad and Cora are both dead!
Not yet.
Is she really dying?
She's definitely not getting any better.
There has to be something that we can do. We have to help her.
You can't.
Only I can.
I can save her,
and I can tell you where Sheriff Stilinski is.
But there is a pack of Alphas in this hospital who want me dead.
So I'll help you,
but only when I'm out of here and safe.
Only then.
- Derek, wait! - She was trying to get out.
I was trying to keep from getting killed. You can't blame me for that.
If you want to show you're one of the good guys, then heal her.
Not until I'm safe.
I'd like to volunteer a different method of persuasion.
- Let's torture her. - Works for me.
Um, can I have your attention?
Mr. Deucalion...
Excuse me, just Deucalion,
requests you bring the woman calling herself Jennifer Blake
to the E.R. reception.
Do this, and everyone else can leave.
You have 10 minutes.
- He's not gonna hurt her. - Shut up.
He won't!
Scott, you know why.
Tell them it's true.
What does she mean?
You're not the only one he wants in his pack.
- Looks like the evacuation's over. - Are you catching a scent?
No, not with the rain this heavy.
Deucalion doesn't just want an Alpha pack. He wants perfection.
That means adding the rarest of Alphas to his ranks.
A true Alpha.
What's that?
The kind that doesn't have to steal his power from another.
One that can rise by the force of his own will.
Our little Scott.
It doesn't matter.
We still need to get her out of here.
- Scott, your mom... - My mom
said there's one more ambulance coming in 20 minutes.
And I don't think we've been here that long, so if we can get down to the garage,
get to the last ambulance, we can get out of here.
The twins aren't gonna let us just walk out.
- I'll distract them. - You mean fight them.
Whatever I have to do.
I'll help you.
Um, sorry, but I'm not going anywhere without you, Derek.
I'll do it.
But I'd prefer to be out there with an advantage.
An advantage like what? You mean like a weapon?
Something better than a baseball bat.
Hey, wait. What about these?
- Do you know how to use those? - Well, no.
Put 'em down.
Epinephrine?
That's only gonna make him stronger.
How strong?
All right, boys. Let's rumble.
It's still here!
Derek, over here.
Julia.
It is you.
You can't beat her on your own.
That's why we're gonna run.
Wait, wait! The elevator!
Thank you.
That was more than helpful.
What now? What do you want with me?
You?
You're my gesture of goodwill.
What?
Go find your son.
Do yourself a favor, Melissa.
Be careful out there.
Okay, okay, okay. We're okay. We're all right. You okay? How you doing?
Why do you look like you're not breathing?
Because you aren't breathing, are you?
Oh, no. Oh, God. Oh, no, no, no. Why are you not breathing? Come on.
Okay, okay, okay.
You can do this. Here we go, tilt the head.
Fingers on the chin. Clear the throat.
Great, nothing. I see nothing. Okay, all right, so, uh...
Just pinch the nose and blow.
Oh, come on, Cora.
Come on, Cora.
If you're thinking service hatch,
they bolt from the outside, so you'd have to break it.
All you'd end up doing is creating a lot of noise,
telling them exactly where we are.
Kali already knows.
Not necessarily. She saw that we got in,
but she might not know that we didn't get out.
Yeah, well, if I get through, then we can go to another floor.
Or you'd end up fighting them alone in an elevator shaft.
They'll rip my head off before you even have a chance to land a punch.
Then someone needs to get the backup generator running again.
Come on.
Oh, come on, Cora.
Come on, breathe.
Come on, Cora, breathe.
Oh!
You know, next time I put my lips to your mouth,
you better be awake.
That shot didn't last very long.
Those twins are really starting to piss me off.
How the hell are we supposed to get past them?
Personally, I think if we keep letting them beat the living crap out of us,
they'll tire and give up.
You couldn't have waited, like, 10 seconds?
They didn't get out, did they?
"Don't move. On our way."
You just hold on a little longer, okay?
Trust me, if anyone's gonna get us out of this, it's Scott.
Can't believe I just said that.
You know, I actually used to be the one with the plan.
Well, or at least a plan B.
Now I don't know. Now I'm thinking maybe you were right.
You know, maybe... Maybe we are pretty much useless.
Maybe all we really do is show up and find the bodies.
I don't want to find my father's body.
You know, you're a lot easier to talk to when you're completely unconscious.
I'm gonna take that as a sign you're a little worried.
Stay close to me.
I think I heard something.
Where?
Below us.
Stiles! Stiles, open the door!
Sorry.
Help me get him in.
Where's Derek and Jennifer?
I have to go back for them and my mom.
Okay, two problems. Kali's got the keys to this thing,
and I just saw the twins, like, 30 seconds ago.
Stay here.
Where is she?
We're trying not to hurt you.
- Try harder. - Hey!
I'd like to try something.
Sweetheart, get up!
Come on.
Anything?
Derek, I know what you're thinking.
That I'm using you,
that everything that has happened between us is a lie,
or that I'm evil.
A bitch.
But I hope you're not thinking
the most superficial thought.
"Is that her real face?
"The slashed, mutilated face revealed by the mistletoe.
"Is that what she really looks like?"
You should have kept his mother.
Is that so?
You have a soft spot for him.
I have an investment I'm trying to mature.
If you want to talk about soft spots,
let's talk about Jennifer Blake.
Or... What was her name again?
Julia.
Ah.
Julia Baccari.
That was my name.
I don't care.
I guess I should have changed it to something
with different first letters.
I think I read somewhere that people always pick aliases
that are subconsciously derivative of their original name.
It's a way of not completely letting go of your identity,
since your name is so tied to your sense of self.
Do you know what else is?
Your face.
The one that's supposed to be staring back at you in the mirror.
Not some hacked up atrocity you can't even recognize.
I still don't care.
But I bet you're curious.
I bet you wonder exactly what happened.
You were an emissary.
They tried killing you along with the rest of the pack.
Mystery solved.
I was Kali's emissary.
And I was the one she couldn't kill.
I didn't understand why I had to kill her too.
She was harmless.
But I did it because you wanted me to.
I did everything you asked to be a part of this pack.
You did it to be with Ennis,
so don't point that accusing toe at me.
And as for harmless,
how harmless does she look now?
I thought she was dead.
Did you?
Are you asking
if maybe there was a moment of uncertainty?
That when I walked away thinking she was dead,
that maybe I turned back?
And maybe I saw her there, lying perfectly still,
but I focused my hearing anyway.
Listened to the sound of her heart still beating,
still fighting for life, and I thought,
"I could go back and finish it,
"or I could let someone I love die peacefully."
And maybe I just kept walking.
My heart bleeds for you, Kali.
Apparently hers could have bled a little more.
For years, the Nemeton's power was virtually gone,
like the dying ember of a burned out fire.
But a few months earlier,
something happened
that caused that ember to glow a little brighter.
Something that gave it a spark of power again.
The sacrifice of a virgin.
You didn't know what you were doing back then,
but killing Paige in the root cellar,
sacrificing her there, gave power to the Nemeton.
You gave it power again.
You gave me power.
Just enough to hold on to life a little longer.
Long enough to be found.
She's still breathing.
He just let me go, said it was a gesture of goodwill.
No other reason.
He had to have a reason.
I don't think he does anything without a reason.
Well, if that means I should continue to be profoundly terrified,
then don't worry about it, I got that covered.
You know mistletoe is important to Druids,
but do you know the myth of why people kiss under mistletoe?
No.
It's a Norse myth.
Balder, the son of Odin, was the most beloved by the other Gods,
so much that they wanted to protect him
from all the dangers in the world.
His mother, Frigg, took an oath
from fire and water, metal, stone, and every living thing,
that they would never hurt Balder.
At a gathering, they tested him.
Stones, arrows, and flame were all hurled at him.
Nothing worked.
But there was one God who wasn't so enamored of Balder.
The God of mischief, Loki.
Loki discovered that Frigg had forgotten to ask mistletoe,
a tiny, seemingly harmless plant,
and completely overlooked.
Loki fashioned a dart out of mistletoe, and it killed Balder.
Frigg was heartbroken.
She decreed that mistletoe would never again be used as a weapon
and that she would place a kiss on anyone who passed under it.
So now we hang mistletoe underneath our door
during the holidays
so that we will never overlook it again.
We were the overlooked,
the emissaries.
It was a mistake Deucalion and the Alphas
should never have made,
because I made an oath of my own.
From virgins and warriors,
from healers, philosophers, and guardians,
to loan me their power so that I could teach these monsters
that their monstrous actions would never be overlooked.
- You killed innocent people. - So have you.
I know the real color of your eyes, Derek.
And I know what it means.
I'm not asking you to save just my life.
I'm asking you to save everyone they'll ever hurt again.
You can't beat them.
Are you sure about that?
Boyd asked you right before he died,
what happens to a werewolf during a lunar eclipse?
You didn't get the chance to tell him,
but you know, don't you?
What happens, Derek?
During the total lunar eclipse?
We lose all our power.
- So then they're essentially trapped? - Yeah, right.
There's no way of getting them out without turning the power back on.
But wait, wait, wait, if the power's back on,
they're gonna hear the elevator moving, right?
And they'll be on Jennifer and Derek as soon as it stops.
We can't get in a fight with them.
- You've got us now. - It's too much to risk.
They want her dead, and if she dies,
there's nothing that we can do for Stiles's dad or Cora.
I don't even think I know which teacher this is.
She's... She's the one with the brown hair. She's kind of hot.
No, it's... Just an observation.
I've got an idea.
What are they doing?
Plotting.
- You ready? - Yeah.
You're not nervous, are you?
Do I look nervous?
No, not at all.
- Did he look nervous? - Terrified.
Yeah, I can still hear you, very, very clearly.
Just go as soon as you see them, okay?
Yeah. Yeah, I got it.
I don't think they're on this floor.
Come on. Oh, God.
Derek, please look at me.
All right, come on, come on, come on!
- I got her. - Okay, get the door.
Stiles, let's go!
Stiles!
Mom.
Scott! Scott, wait!
- Come on, we gotta go. Drive, you idiot. - I can't. Not without Scott.
Come on, you want the Argents dead too? Make a choice!
Oh, for the love of God! Go, now!
All right!
Mom! Mom!
They're gone.
Guardians, Scott.
If you were with me, I could've told you what it meant.
I could've warned you.
Let me help you, Scott.
Let's help each other.
You help me catch her,
and I'll help you get your mother and Stiles's father back.
Scott.
Scott, don't do this. Don't go with him.
I don't know what else to do.
No, there's...
Scott, there's got to be something else, okay?
We always... We always have a plan B.
Not this time.
Scott.
I'm gonna find your dad.
I promise.
Scott!
Hey. Hey.
You all right?
Oh, God, where are we?
I don't know.
Looks like a root cellar to me,
but, uh, she called it something different.
She called it a
Nemeton.
