- THEO: Previously on - Teen Wolf...
There's four steps.
- We get into Eichen, - we get into the Closed Unit,
get Lydia, get out.
If we don't do this,
- she's going to die - in there tonight.
We're in. We did it.
LYDIA: Stiles...
- You're going to die - if you stay.
Hello, this is Natalie Martin.
I need to see
my daughter immediately.
We're here for Lydia Martin.
- Lydia, I'm not - leaving you here.
(ALARM BLARING)
(GASPS)
I'm looking for a Hellhound.
- DR. VALACK: - You wanted a Hellhound...
(DEEP GROWLING)
I think you found one.
(GRUNTS, SCREAMS)
(ROARING)
Come on.
- We're getting - Lydia out of here.
(MUSIC PLAYING)
(PARRISH ROARING)
(GROWLS)
- Back off. - (GRUNTS)
I said back off.
Take him.
- The guy's on fire. - You'll heal. Do it.
(SNARLS)
(GROWLING)
(SCREAMING)
Theo, this isn't working.
(WHIRRING)
(SCREAMING)
(GROANS)
- Sorry Theo, but I'm not - done with her yet.
(ROARS)
(SCREAMING)
(GRUNTS)
(GROWLING)
(GROANS)
(GRUNTING)
(MUSIC PLAYING)
STILES: (YELLS) Hey! Lydia!
(GRUNTING)
Lydia!
(THEME MUSIC PLAYING)
(MUSIC PLAYING)
(HAYDEN EXHALES)
Don't go.
I have to.
Stay.
Stay here?
With you?
Stay with us.
(MUSIC PLAYING)
- Theo thinks he's gonna - be able to take its power.
(SCOFFS) He's crazy.
- It's gonna - rip his head off.
- But you think Scott - can save everyone?
I know he can.
It's different now.
I think dying
did something to him.
- It did something - to me, too.
But none of it was good.
What if it happened again?
What if you got hurt?
- What would you - want me to do?
Now that you know everything.
(MUSIC PLAYING)
- DEUCALION: Starting - to question
where your loyalties lie?
- Or maybe you're starting - to understand your role.
What role?
Why would Theo
leave you here?
Why not leave
Josh or Corey?
- You're stronger - and faster than both.
And more fearless.
- I know why - I'm stuck here with you.
- Because when it - comes to Liam,
I'm a liability.
- You could leave. - You could go off to help them.
No one has to know.
Except for you.
Oh, I'm no friend to Theo.
You want to help Liam?
Worry less about
being a liability
and more about
your ability to lie.
Does anyone have eyes
on the Closed Unit?
I need a status report.
- GUARD: It's a war zone - down here.
Uh... 10-4.
(MUSIC PLAYING)
- And what about the patients? - Lydia Martin?
Who is this?
It's... Unit Nine.
- There is no Unit Nine. - Who is this?
How did you get...
- All right. We need - to figure out another way
to get into this Closed Unit.
- How do we get through - the mountain ash?
I don't know yet.
- But there's somebody else here - that might be able to help us.
Who?
Meredith.
- (GRUNTS) - BOY: Let me try.
(MUSIC PLAYING)
- You're not gonna find her - without me.
(MUSIC PLAYING)
(SNARLS)
- (ELECTRICITY CRACKLING) - (MUSIC PLAYING)
- I don't know how long - I'm going to last.
How did you stop it before?
- Scott carried me outside, - which almost killed him.
Okay, uh...
- Maybe we could try - grounding you to something.
- You have a degree - in electrical engineering?
- 'Cause I don't know - how to do that.
(EXCLAIMS)
You have to get out of here.
I can't leave you.
- I should've stayed in the - desert with the Skinwalkers.
I can't control this.
I'm never going
to be able to.
- Kira, it worked. - (MUSIC PLAYING)
You saw it work.
- You controlled it enough - to cause the brownout.
You can stop it.
- (DISTORTED) I can't! - (MUSIC PLAYING)
Malia, go!
(HUFFING)
(ELECTROMAGNETIC HUMMING)
(CRACKLING)

(CELL DOOR BEEPS AND OPENS)
(MUSIC PLAYING)
Meredith?
Meredith? It's Scott.
Scott McCall.
THEO: Stiles.
- I want her - out of here, too.
(MUSIC PLAYING)
- I've got her scent. - What do you want?
What's the difference?
- Huh. - I can find her. You can't.
(STEAM BLOWING)
(MUSIC PLAYING)
- It leads to the tunnels, - doesn't it?
There's miles of them.
- STILES: They could be - anywhere by now.
SCOTT: Hey. Meredith,
can you hear me?
We need your help.
We're trying to find Lydia.
- We're trying - to get her out of here.
- Scott, I think - we better go.
Meredith, listen.
- There has to be another way - to get to Lydia.
- We can't get past - the mountain ash.
How do we find her?
Scott...
I could hurt you.
(MUSIC PLAYING)
Okay.
- (GASPS) - (MUSIC PLAYING)
(ELECTRICITY CRACKLING)
Kira?
Kira.
- JOSH: - I wouldn't do that.
(MUSIC PLAYING)
- Electricity's still - coming off her.
I can feel it from here.
I can help her.
Why?
- JOSH: Because - I need your help.
With him.
(DISTORTED) Meredith?
(MUSIC PLAYING)
(INAUDIBLE)
(DISTANT INDISTINCT SPEECH)
(MUSIC PLAYING)
(BOTH GRUNT)
(ROARS)
(ROARING)
(GROANS)
(PANTING)
(GROWLING)
Oh, sh...
(SCREAMING)
- MEREDITH: She doesn't - have much time.
What's happening to her?
(ECHOES) She's being
consumed by her power.
Dr. Valack thinks
it's worth it if she can
answer the question.
What question?
Who is the Beast?
She can answer that?
Not yet.
- Not until the screams - in her head are loud enough
to kill her.
SCOTT: How do I get to her?
You can't.
- You won't be able - to get past the mountain ash.
But someone else
might be able to.
Who?
The Hellhound.
You mean Parrish?
They're connected.
- Find the Hellhound, - (MUSIC PLAYING)
and he'll find the Banshee.
(SCREAMING)
(MUSIC PLAYING)
- DEUCALION: - Five texts in two minutes?
- Someone's trying - to get your attention.
Maybe you should go.
- I'm obviously not - going anywhere.
- Could you please - shut the hell up?
DEUCALION: I have a feeling
you and I are going
to be friends, Hayden.
I think we're going
to discover a lot of common
ground beneath our feet.
(CELL PHONE VIBRATES)
- Now is that really necessary? - (MUSIC PLAYING)
- It's Kanima Venom - from Tracy.
- Enough to paralyze you - for a couple hours.
If we're going to be friends,
Hayden, you really need
to learn to trust me.
Now I trust you.
(RAGGED BREATHING)
MEREDITH: Save her.
(DOOR SLAMS OPEN)
LIAM: Oh!
(PANTING)
Is he out?
Yeah.
Okay.
- STILES: I thought - you had her scent.
I lost it.
So find it again.
- What do you smell - down here, Stiles?
- Chemicals - and fecal matter.
- Although, I'm pretty sure - the fecal matter is you.
I smell it, too.
It's all that I can smell.
- Which is why I'm trying - something else.
- So can you shut up - and let me concentrate?
I'm gonna find her.
- You know you won't, Stiles. - You're going
to have to trust me.
Trust you?
- The guy who murdered his - own sister when he was nine?
Yeah, I was
nine years old.
(MUSIC PLAYING)
- I also believed a guy - in a red suit
- came down the chimney - to deliver presents.
- So when three people - in leather masks showed up
- and said that my sister - wanted me to have her heart,
I believed them, too.
- So then together - you gutted and killed her.
That's a beautiful story.
- I watched her fall - into the water and freeze
to death in minutes.
- Do you think I had - any idea what was going on?
I think you pushed her.
And I think you liked it.
(LYDIA SCREAMING)
What direction was that?
Where is it coming from?
Everywhere.
(GASPS)
(GROANS)
- DR. VALACK: Just hold on - a little longer, Lydia.
(GROANS)
You can make it.
- I want you to focus - on this, Lydia.
- And what other sounds - you hear now,
push them aside.
(WHIMPERS)
Focus on this sound.
(CRACKLING RHYTHMICALLY)
(SOFTLY) That's it.
- Focus on this - sound and my voice.
All right, Lydia?
(LYDIA GASPS)
Don't worry, Lydia.
- Nurse Cross wasn't nearly - as strong as you are.
(WHIMPERING)
(ELECTRICITY CRACKLING)
SCOTT: Parrish? Parrish.
- Parrish. Parrish, hey. - Can you hear me?
How did I get here?
- We don't know. We just - followed the burning smell.
SCOTT: Parrish, listen.
Eichen's in lockdown.
- There's no way - for us to get out
unless Plan B works.
Plan B?
What's Plan B?
Don't worry about it.
- Right now, we need you - to find Lydia.
- Me? - LIAM: Actually,
not completely you.
We kind of need
the other you.
SCOTT: The Hellhound.
(GROANS)
Why isn't he healing?
- Maybe he can't. - Maybe it's too much.
Or maybe it's the pain.
(GROANS)
He's going to die, isn't he?
- His heartbeat's - getting slower.
What do we do?
- You can't heal him, - can you?
No, but I can
take his pain.
- It could help. It might even - get him to start healing.
(MUSIC PLAYING)
Then do it.
You first.
(ELECTRICITY CRACKLING)
You said you could help her.
- Yeah, but it's not like taking - voltage from a car battery.
- She's got a lot more - power than that.
(GROANS)
- Are you going to do - something or not?
- When you help her. - I don't trust you.
I don't trust you either.
- All right. - We go at the same time.
You ready?
All right, here we go.
(MALIA GRUNTS)
(SCREAMS)
Nothing.
- Great. You're just - as useless as I am.
- I'm trying to help - save her life.
- Would you just - drop the altruistic crap?
- You want Lydia because - she gets you to Parrish,
- you want Parrish 'cause - he gets you to the Beast.
- So what? - I want it dead, too.
- After you take - its power, right?
- We know why - you got the talons
- and we know - you're looking for Deucalion.
I found Deucalion.
You're right.
- I'm going to help - Parrish stop the Beast.
I'm going to take its power.
- And then I'm going - to break its neck.
- So maybe I'm not - the good guy in your eyes,
- but I might end up - being the guy that
saves all your asses.
Break it.
What?
- The sound travels - through the pipe.
- You'll hear better, - dumbass. Break it.
- DR. VALACK: - Lydia?
Can you hear me?
What do you want from me?
- DR. VALACK: I want your help - against the Dread Doctors.
They ruined me.
Destroyed me.
- They drove me - to obsession,
- consigned me - to professional ridicule.
- People thought - I was a monster
- when I was simply trying - to open their eyes.
- Now you want me - to be your eyes.
You'll see things, Lydia.
- Things that other - people cannot see.
You may not survive,
- but you might save - the lives of your friends.
(PANTING)
Do it!
- DR. VALACK: We have - to slow your mind first.
- There's too much - activity in your brain.
- We have to get - from a gamma wave
to a theta.
(MOANS)
It's too loud. I can't.
- If I try the mask now - it will kill you.
- You have to calm - your mind.
- You understand what - they've created.
The Beast.
- DR. VALACK: The Beast - of Gevaudan.
- An engineered - version of it.
- But it's not yet - fully grown.
It's still bound to its host,
the teenage Chimera inside.
- And it still requires the - Dread Doctors' protection.
Damnatio Memoriae.
DR. VALACK: That's right.
The Beast was a man first.
A human killer
in the late 1700s.
- The Dread Doctors are trying - to get it to remember itself.
To remember the man.
When that happens,
the teenager is gone.
(GROANS)
- Anybody know how - we're supposed
to get out of here?
- This place is still - in lockdown.
It's not just locked.
Yeah, I can feel it, too.
- What are we supposed to do? - Just wait here?
MALIA: There's a Plan B.
- We've got a guy - on the outside in case
this happens.
Who?
Mason.
- Mason's going to unlock - the lockdown?
- How's he going - to do that?
- KIRA: He's got the blueprints - of the building.
- And he has the full map - of Eichen's electrical system.
- All he has to do is get - into the transformer shed
behind the building.
- Don't worry. Mason knows - exactly what he's doing.
Liam, call me back,
I have no idea what to do.
(MUSIC PLAYING)
And I'm panicking.
- I'm completely - and totally panicking.
- I drove around this building, - like, four times
- and I can't find - this transformer shed.
- Well, actually, - that's partially right.
- Because I found where - the transformer shed
is supposed to be.
But it's not a shed anymore.
It's a wall.
Like, a very big wall.
- So, I mean, - I tried calling Hayden.
- And she still isn't here, - and I heard alarms go off.
- Now I don't know - what to do.
So, Liam, just call me.
(MUSIC CONTINUES PLAYING)
- DR. VALACK: This teenager, - Lydia, is the last
Genetic Chimera.
- A young man - or a young woman,
- maybe even - someone you know.
- A success where Theo - and the others were failures.
- But we went through the list - of Genetic Chimeras.
There's no one else.
- There must be - one you missed.
Another way they could
have two sets of DNA.
- If you could see the face - of this teenager,
discover its identity,
- then your friends - would have a fighting chance.
- The mask can - help you see.
- (THUD) - STILES: Lydia!
(GRUNTS)
(SHRIEKS)
STILES: Lydia!
- What the hell are you doing? - Get the door.
I'm trying.
(WHIMPERING)
(STILES SHOUTING)
- I'm sorry. - But time's up.
(SCREAMING)
(MUSIC PLAYING)
You came back.
- We're getting you - out of here, okay?
- You can't. - It's too dangerous.
- Lydia, please shut up - and let me save your life.
(MUSIC PLAYING)
(ENGINE STARTING)
Okay, here we go.
Gonna ram the wall.
Gonna ram it with my car.
Just smash through it.
Take out the power.
And save my friends.
Here we go.
All right. Just ram it
and destroy my beautiful car
that my parents bought me
on my birthday,
but I'ma save my friends.
Here we go.
- Ram the wall. - All right.
(HUFFING)
What the hell
are you doing?
Oh, thank God.
Can we use your car?
Are you kidding?
- A car is not - getting through that.
- What? - You have any better ideas?
Uh...
MASON: Hayden?
Hayden.
- Wait. Whoa. Wait, Hayden. - Whoa, whoa, wait!
(THUD)
HAYDEN: I'm in!
Okay. Um...
- Okay. - There's two red levers.
- You're going - to pull them both.
You see them?
HAYDEN: I see 10.
- Two. - HAYDEN: No. 10.
There's ten red levers.
What do I do?
Mason?
- Mason, what am - I supposed to do?
Parrish?
- How's he going to get - through the mountain ash?
- He's burning it right out - of the walls.
- Okay. You gotta try - and stay on your feet.
- (LYDIA GROANS) - The plan didn't
work out too well.
- So I'm gonna need - your help, okay?
LYDIA: You had a plan?
- STILES: Yeah. - It was good on paper.
Not too much in reality.
- LYDIA: - I can't hold it.
(ECHOING CALLS)
Lydia...
Stiles, run!
(GROANS)
(GASPING)
(SCREAMING)
(ALL COUGHING)
(LYDIA GASPING)
Where to?
This way.
Come on.
Hayden, just pull them all.
Just pull them all!
There's a gate up ahead.
What about Mason?
He's on it. Trust me.
(HAYDEN PULLING LEVERS)
(MUSIC PLAYING)
- What's... - What's happening?
Plan B.
- SCOTT: Liam, slow down. - STILES: Liam, wait!
(GRUNTS)
(PANTING)
I told you.
(MUSIC PLAYING)
He did it.
- We gotta get - to Stiles' Jeep.
(VEHICLE APPROACHING)
PARRISH: Can you stand?
Is she okay?
- No, we need to go. - Give me the keys.
- We gotta get her - to the clinic.
(SLASHING)
(GROANS)
- Sorry, but she's - coming with me.
- Okay. Tracy, just wait. - You don't know
what's about to happen.
- TRACY: I'm taking her. - That's what's happening.
- And none of are you - going to do a thing...
- (ELECTRICITY CRACKLES) - (GROANS)
(MUSIC PLAYING)
- Could somebody - please get my daughter
out of this hellhole?
- STILES: Scott. - Yeah. I'm trying, I'm trying.
- We're almost there. - Lydia, just hold on, okay?
(LYDIA SCREAMS)
(MUSIC PLAYING)
STILES: Hey.
- Lydia, Lydia, hey, hey, - hey, hey, hey.
- Look. You're gonna - get through this, okay?
- Lydia, look at me, - you're gonna make it.
(BREATHING HEAVILY)
But you're not.
(ENGINE REVVING)
Get her on the table.
(LYDIA GROANING)
(MUSIC PLAYING)
- STILES: Whoa, whoa, whoa. - Hold her.
(SCREAMING)
- Doc, think you gotta - do something.
DEATON: I will.
- But right now, I need - you to keep her still.
(GRUNTS)
Steady.
- Steady. - What the hell is that?
Mistletoe.
- Mistletoe? She's got - a fricking hole in her head.
- (GROANS) - Stiles, help.
(GRUNTS)
DEATON: Steady.
(SCREAMING)
(PANTING)
STILES: Lydia.
Lydia?
Lydia.
Lydia, come on.
- No, no, no, no, no. - Come on, Lydia.
Wake up.
Come on.
- Wake up. Can you hear me? - Lydia.
Lydia, open your eyes.
Come on, come on.
- STILES: Come on. - Listen to me, Lydia.
- Hey, show me - your eyes, okay?
(MUSIC PLAYING)
- Lydia, you have - to open your eyes.
(MOANS)
You okay?
You're okay.
Want to try to sit up?
Mom?
Oh, honey.
- LYDIA: - They saved my life, Mom.
Stiles saved me.
(MUSIC CONTINUES PLAYING)
- I'm not paying - for the windows.
- I said it was for - emergencies only.
I had an emergency.
- DEUCALION: - Don't worry, Theo.
- A little dissension - in the ranks
is perfectly healthy.
- Did you find what you - were looking for?
No.
- But I think I might have - found something better.
A way to answer the question.
Who is the Beast?
(MUSIC PLAYING)
