- DEREK: Previously - on Teen Wolf...
Everyone around me gets hurt.
- DEATON: Mountain Ash is - some of what you'll use
to create the barrier.
- The only way to - protect one person
is to kill another.
- A certain level - of electric current
- will keep you - from transforming.
- ETHAN: Derek - killed one of ours.
- Either he joins our pack, - or Kali goes after him
and we kill him.
- Okay, keep pressure on it. - The doctor is on her way.
- Does anyone know - where Dr. Hilyard is?
- (INDISTINCT - P.A. ANNOUNCEMENT)
There you go.
Oh, thank God.
I'm starving.
Oh.
I'm sorry. I'm sorry.
- Thank you for - bringing me dinner.
Is everything okay?
- Except for half - the accident victims
- in a 10-car pile-up being - rerouted here from downtown,
- and the ER attending - not answering
any of his pages?
Yeah, I'm okay.
- What does "not - answering pages" mean?
- It means that - nobody can find him.
- So now we have to wait - for the on-call to get here.
- Miss? - Yes?
- Excuse me. - Can I kind of please
have something for the pain?
Okay, I'm sorry. I know.
- But actually giving - you something could
complicate things, so...
We really just need to wait
for the doctors, okay?
- Okay, how much longer - on Dr. Hilyard?
Ten minutes.
(CRYING)
Uh...
- You know, - I think I read online
that sometimes human contact
can help with pain.
(WHIMPERING)
(GASPS)
- ETHAN: Someone... - Someone help me!
I need help!
It's Dr. Hilyard again.
- Can you let Melissa know - that it may be
more than 10 minutes?
- I think there's - an accident up ahead.
- RECEPTIONIST: Yeah, - a 10-car pile-up, which
is why we need you here.
- I'm going - as fast as I can.
Okay.
- Okay, gentle, - gentle, gentle!
(SCREAMS)
- What did you do to him? - Nothing.
- He said he was - having chest pains
and trouble breathing,
- but it just - kept getting worse.
This is not good.
- How much longer - on Dr. Hilyard?
- His larynx has - shifted to the side.
- I think it's - a tension pneumothorax.
Mistletoe.
(MOANING)
Can you two
please go back to
the waiting room?
- Where are - the nurses and the doctors?
Where is everyone?
- It's a full house tonight. - They're tending
to other patients.
- Okay. Well, Mom, - how can we help?
- Honey, you can't. - His lung is collapsed.
- His heart is being - pushed against his
chest cavity now.
- He's gonna die, - isn't he?
No. No, he's not.
Scott, you grab the tape.
- You grab those scissors - and cut his shirt open.
(GRUNTS)
- (GASPING) - Okay.
- (GASPS) Mom, - he's not breathing.
I know, I know.
Okay.
How did you get in?
(GRUNTING)
(YELPING)
- (TIRES SQUEAL) - (GASPS)
(HORNS HONKING)
(MUFFLED YELPING)
(SCREAMING)
(AIR HISSING)
(INHALES)
(EXHALES)
Okay, here we go.
Thank you.
No problem.
What?
That was awesome.
(LAUGHS)
- It wasn't a... - No problem, you know.
I mean, it wasn't a big deal.
(LAUGHS)
(EXHALES)
I know you're not
gonna believe me,
but I didn't do anything.
- All I know is that - the minute that you got here,
- you went right for Danny. - And your brother
went for Lydia.
- We're not gonna hurt him. - Why should I believe you?
- Because we knew one - of them was gonna
be important to you,
and now we know it's Lydia.
What is it?
(SIREN WAILING)
STILES: Two missing...
Hang on there.
- They were both - in the car?
- No, Dad. - They're trying to tell you
- that it was two separate - kidnappings, okay?
Two doctors, both gone.
So whose car is this?
Dr. Hilyard.
The on-call doctor.
The ER attending is
the one that
never made it in.
- Let me just focus on - getting your story
first, all right?
Yeah.
Boys, give us a second.
- (SIREN WAILING - IN THE DISTANCE)
- These are definitely - sacrifices, right?
- Yeah, it's one - Deaton mentioned. Healers.
- What about Danny? - He threw up mistletoe.
That's not a coincidence.
- And if he hadn't - been with Ethan,
he probably would've died.
And Danny's not a healer?
I...
Can you hear that?
They found a body.
(CAMERA CLICKING)
(WHISPERING)
(ALARM BLARING)
What does it mean?
It means they're coming.
Tonight.
(GASPS)
(SIGHS) Really, boys?
Boys!
- What do you - think you're doing?
- Uh... We were - watching over you.
- We wanted to make sure - you weren't
the third sacrifice.
But both of you were asleep.
You were on watch last.
- What are you talking about? - You were on watch last.
No, you were on watch last.
- I might've been - on watch last.
(LAUGHS)
My heroes.
- Wait, didn't you say - that they were all doctors?
- I mean, I haven't had - an M.D. recently attached
to the end of my name,
- so I think - I'm in the clear.
Yeah, but it could just come
under any kind
of healer, Mom.
- And you were definitely - a healer last night.
Yeah, well, I'm not
gonna be anyone's
human sacrifice today.
- So, both of you, - get your butts to school.
Good morning.
- As you all know, - Mr. Harris is still missing.
I mean, sick.
Anyway, I'm filling in
while we all hope and pray
for a more
qualified substitute
to take my place.
- Okay. So let's get started, - shall we?
Hey, my dad said that
the ER attending
wasn't strangled,
- but did die - from asphyxiation.
They just don't know how.
- Do you think - the on-call doctor
could still be alive?
I don't know.
- But, Scott, there's got - to be at least 20 other
doctors in that hospital.
At least. You know?
Any one of them
could be next.
(CELL PHONE BUZZES)
- Hey, Doc. Sorry, - I'm in class right now.
Can I call you back later?
DEATON: Unfortunately, no.
I honestly thought
I might never have to
burden you like this,
but I'm afraid,
at the moment,
you're my only hope.
I'm going to be taken.
I need you to find me.
(HANGS UP)
- Doc, Doc, Doc, Doc, - what's happening?
(WINGS FLUTTERING)
DEREK: Go back to school.
Well, actually,
we can't.
Boyd and I are incredibly
and unbelievably sick.
- DEREK: With what, - brain damage?
- Well, I have - a migraine
- and Boyd here has - explosive diarrhea.
We're here to protect you.
You're here to protect me?
Well, I'm
in trouble then.
- Well, actually, Boyd here - came up with a plan.
Yeah, I thought about
the time Gerard had me
and Erica locked up,
- tied up with electrical wires - pushing current through us.
- I was wondering how we could - do something like that.
But on a bigger scale.
How did you know?
- Stiles called me as - soon as you left school.
I'm sorry.
Your boss' car
is still here
- and the back door - was wide open.
Scott.
- I need you to - tell me everything.
- BOYD: In a pool of - electrified water,
- it can take up to - 50 milliamps to
kill a normal human,
- less than the power it takes - to turn on a light bulb.
That's comforting.
- If we disable - the circuit interrupter
- in the building's - electrical room,
the current will keep coming,
- and anyone who - steps foot in here,
- they'll get - a pretty shocking surprise.
- Especially - someone who's barefoot.
All right,
- we're gonna do - everything we can.
- Right now, - the best thing you can do
is go back to school.
We have to tell him.
- You mean, - like, "tell him" tell him?
- Or tell him something else - that isn't telling him
- what I think you - want to tell him?
You know what I mean.
- You remember how - your mom reacted?
- She didn't look you in - the eye for, like, a week.
And she got over it.
- And it actually - made us closer.
- I don't know, dude. - I mean, look at him.
- Come on, he's completely - overwhelmed as it is.
- He's overwhelmed - because he has no clue
what's happening.
- He's got people - dying in his town,
- the town that he's - supposed to protect.
- And it's not his fault - that he doesn't
know what's happening.
- He's gonna find - out sooner or later.
- Okay, but is now - really the right time?
- What if not telling him now - gets someone else killed?
What if telling him
gets him killed, huh?
- I mean, okay, look, - I get that Deaton's been
like a father to you.
- I get that, okay? - But this isn't...
- Scott, - this is my actual father.
I can't...
- I can't lose both of - my parents, all right?
Not both of them.
You're right.
(SIGHS) No, I'm not.
I'm not right.
I'll tell him.
I'll help you.
(SIGHS)
MORELL: Please.
Whatever you need,
- however you can - help find my brother.
- STILINSKI: Will you - excuse us for a minute?
Thank you.
- Listen closely, - both of you.
- No sheriff, - deputy or detective
- is going to be - able to find him.
- You don't have to - ask us for help.
- Actually, - I'm trying to help you.
- Because if you're - going to find my brother,
- then you need to - use the one person
- who might actually - have an ability
to seek out the supernatural.
Lydia.
(FIRE ALARM RINGING)
Oh, man.
(BOTH SIGH)
Where are you going?
- Dude, it's a fire alarm. - (SCOFFS)
When in high school
has a fire alarm
actually been a real fire?
- That's exactly - the kind of thing
- you'd expect two - dumbass students to say
- just before - getting burned alive.
You first.
Go.
- You don't have very good - taste in guys, do you?
Hey.
- It's Dr. Hilyard, - isn't it?
Yeah.
Oh, God. Okay.
- Did she have ligature marks - around her throat?
- No. How do you - know about that?
- I need you to take a look - at the other body with me.
- I think I know - how they both died.
- And I think it's gonna - help you find Scott's boss.
(SCOFFS)
Is there a problem?
Yeah, Derek would
like to kindly ask you
to stop seeing Aidan.
Which means that
if I catch you
with him again,
- I'm not going to - pull the fire alarm.
- I'm going to pull your - tongue out of your head.
Sweetheart, my last boyfriend
was a homicidal lizard.
So, I think I can
handle a werewolf.
Let go.
- I said... - STILES: Let go.
I said, "Let go."
(CELL PHONE BUZZES)
(RHYTHMIC TAPPING)
A Ouija board?
- Also called a spirit board. - And it's worth a shot.
A shot in the dark.
- Would you just try it, - please, okay?
- Let's not forget - who this is for.
- Scott's boss, the guy - who has saved our
collective asses
on more than one occasion.
Okay, so do we all do this?
Yeah. Yeah.
You guys ready?
Yeah.
Yes.
Where's Dr. Deaton?
What?
Aren't you gonna answer it?
Oh, I don't know the answer.
- I thought we were asking - some sort of spirit.
- Well, do you know - any spirits?
- Is she for real? - (GROANS)
(CANE TAPPING)
- DEUCALION: Do you know - what a metronome is, Scott?
- It's a tool to help you - maintain a steady rhythm
once you've set the tempo.
Something tells me
the tempo of your life
has sped up considerably
in the last few hours.
If you'd like,
I could help slow it down
to a more manageable pace.
How?
By helping you find Deaton.
Okay, these are
Deaton's keys
for the clinic.
- Close your eyes, - and I'm gonna put
'em in your hand,
- and then we're - just gonna try and see
- if you can feel out - for his location.
It's called psychometry.
I'm not a psychic.
You're something! Okay?
- Just... Lydia, - put out your hand and...
Ooh.
What?
They're cold.
Lydia, concentrate. Please.
- Trying to save lives here. - For the love of God.
- Yeah, what is it? - What do you see?
Nothing.
- Your heart's pounding, - but it's not fear.
It's anger.
I bet I know what
you're thinking.
- Does he have something to do - with Deaton's disappearance?
Tell you what.
- If you can take - the cane away from me,
- I'll tell you - exactly where he is.
Now, what do you think?
(GRUNTS)
(GROANS)
Impressive.
- But you know I'm not the one - slashing up innocent people,
- praying to ancient gods, - gathering herbs,
- or whatever the hell - druids are supposed to do.
I am part of a pack
that wants Derek dead,
though.
Kali is coming for him.
- So there's a difficult choice - you're about to face,
- because someone is - going to die tonight.
- And whether - that's Derek or Deaton,
that's up to you.
Just tell me where he is.
- I'll give you - a very important clue.
Let the current guide you.
Automatic writing?
- Lydia, what are you doing? - What the hell is that?
A tree.
A...
- Lydia, you're supposed - to be writing words,
- like in sentences, - something like a location,
- something that would - tell us where he is.
- Well, maybe you - should've said that.
- Isn't she supposed to be - some kind of genius?
Genius, yes.
Psychic, no.
- Honestly, I don't know - why you're even
bothering with me anyway.
- Especially since it's - obvious you should be
talking to Danny.
Wait, what? Why Danny?
Because last night,
he was a target.
But he wasn't a sacrifice.
(SIGHS)
- The problem with - no ligature marks
around the neck
- is that both doctors - were still asphyxiated.
So the question is...
- How did they suffocate - if they weren't strangled?
Right.
- Now, take a look - at the wrist marks.
What do they tell you?
His hands were tied.
Not just tied.
Look how deep they go.
- I don't think that's just - from struggling to get out.
- I think - he was suspended.
- Hanging like that, - that means
- they would have to keep - lifting their bodies up
in order to breathe.
- Eventually, - they would lose strength
- and they wouldn't be able - to lift themselves up.
- It's how people used to - die from crucifixion.
- So you think Deaton is - somewhere right now,
hanging by his wrists?
MELISSA: Yeah.
- STILINSKI: And when he - no longer has the strength
- to pull himself up - to catch a breath...
(PANTING)
How long before he dies?
Minutes.
(SCHOOL BELL RINGING)
- But isn't Danny - still in the hospital?
- Yeah. That's where - we're going right now.
- I'll meet you there. - Why?
Is this gonna kill him?
I hope so.
- So I was looking through - one of his drawers,
and I found this.
(ELEVATOR BELL DINGS)
- He wasn't supposed - to be back yet.
- What do I do? - Where do I go?
- (WHISPERING) - What are you doing?
- (WHISPERING) - Nothing.
- Part of you is - doing something.
Oh.
Sorry.
Stop.
- I kind of don't - have control over that.
- Okay, well, - let me turn around.
Yeah, totally.
Allison.
What?
That's worse.
- (LAUGHS) - Shh.
(EXHALES)
(DOOR CLOSES)
See this map?
- Last time we were - in here talking,
my dad put a book over it.
- There was something about - the way he did it.
- It was like he was - trying to cover it.
I don't see anything.
- Yeah, you can't - until you use this.
- He's been tracking - and marking everything.
Cora and Boyd at the bank,
- the office in - the penthouse above us,
all of the dead bodies.
- He has a symbol for - where someone was taken,
- and then a different mark - for where the bodies
are found, see?
Now here's the scary part.
- There have been six - sacrifices, right?
- There are 12 - markings on the map.
SCOTT: What?
What does that mean?
- Did your dad find other - bodies and not tell anyone?
I don't think so.
I think he knows
- where the bodies - are going to be found.
- So one of these six - locations, one of these,
is where Deaton could end up.
- I mean, it doesn't - tell us where he's being
kept right now, but...
- But it's close to - figuring it out.
Yeah.
- (CLICKS) - (ELEVATOR BELL DINGS)
Hey.
I didn't hear you come in.
- Yeah, I was just - doing some homework.
- (WHISPERING) - Danny, you awake?
Danny?
(INHALES DEEPLY)
Wow.
(GROANS)
DANNY: What are you doing?
I'm not doing
anything, Danny.
- This is just a dream - that you're having.
- Why are you going - through my stuff?
Right, but only in
the dream, remember?
Dream.
You're dreaming.
Why would I dream about
you going through my stuff?
- I don't know that, - Danny, okay?
- It's your dream. - Take responsibility for it.
- Shut up and - go back to sleep.
- Oh, Danny boy, - you might've actually
found something here.
- Deaton's got to be - at one of the six locations,
but they're all over town.
- I don't know how - we can get to all of
them fast enough.
- STILES: Well, - we might not have to.
- Danny was doing a project - on something for
Mr. Harris' physics class,
- and I think it - actually means something.
What project?
Something on
telluric currents.
- Did you say currents? - Yeah.
- Isn't the light on that - supposed to be on?
Yeah.
- What does it mean - if it's not?
- Someone cut - the auxiliary power.
- What about the main... - (GENERATOR POWERS DOWN)
Derek.
What do we do now?
We fight.
(POUNDING ON DOOR)
Gonna be honest, Derek.
When Ennis died,
- I thought to myself - I'd just go for it.
Find you and kill you,
wherever you stood.
Then I remembered
how you surround yourself
with these teenagers,
hiding behind them,
and I thought,
"What's a girl got to do
to get you alone?"
- You and me, Derek, - or they tear her apart.
What do you say?
- You think you can - beat me one-on-one?
- I'm gonna rip your throat - out with my teeth.
- (GROWLS) - (ROARS)
- Okay, so, what does - this kid's homework
- have to do with - finding Deaton?
- Because it's not - just homework, okay?
- It's a project on - geomagnetic fields.
They flow through the earth.
- They can even be affected - by lunar phases, all right?
Now, look at this.
- This is a note from Harris - on Danny's proposal.
- "I strongly advise you to - choose another subject.
- "The ideas here, - while innovative
and thoughtful,
"border on pseudo-science.
"Not suitable for class."
- Harris wasn't - just a sacrifice.
- He knew something. - STILES: Now, check this out.
- Allison's dad wasn't the only - one with a map, all right?
Danny had one, too.
- Danny marked all - the telluric currents, okay?
- Now, the weird thing - about Beacon Hills
- is that - it actually is a beacon.
- You wouldn't - believe how much energy
flowing through this earth
is around this town.
Stiles, look, they match.
- All right, - there's three places,
right?
Where they're kidnapped,
- and then the place - where their body was found.
- Look, that's right on - the telluric current.
- So, maybe where - he was sacrificed is
somewhere in between.
Let me see that.
- You said there's - six more bodies
to be found.
Deaton's one of them.
- Got to be somewhere - in between, right?
Stop.
He's in the vault.
He's in the same vault.
- Guys, hold on. - Lydia, we don't have time.
- It's Boyd. - The plan didn't work.
They cut the power.
It's just like he said.
Go. I can save Deaton myself.
- What? Scott, - what about us?
- Cora can't get there - fast enough without you.
Go. We can save both of them.
All right, let's go.
(ENGINE STARTS)
(CRYING)
(SCREAMS)
(GROWLING)
(PANTING)
(GROWLING)
Derek!
No!
Wait!
(GRUNTING LOUDLY)
(SNARLING)
(GRUNTING)
(GROWLING)
(YELLING)
(COUGHING)
- Scott! Let me - give it a shot.
Okay, what
do we do?
- We pull them. - We pull all of them.
(CELL PHONE BUZZING)
Take him!
(GASPING)
- I'm giving you till - the next full moon, Derek.
Make the smart choice.
Join the pack.
- Or next time - I'm killing all of you.
(PANTING)
It's okay.
No, no. No, it's not.
It's not.
It's all okay, Derek.
I'm sorry.
The full moon.
That feeling.
It was worth it.
- Did you know it was - the lunar eclipse?
I always wondered what...
What that felt like
for one of us.
For a werewolf.
Boyd,
what do you think
will happen to us
on the lunar eclipse?
- They can last for hours, - you know?
- Because it's just - the earth's shadow.
- I wonder what - will happen to us.
- Maybe it'll - make us stronger.
- I hope - it'll make us stronger.
(SNARLS)
Boyd.
(CRYING)
- If you know - something about him
- and you're - reluctant to tell me,
- try remembering - it's a long list
of favors and penance
- before you're - redeemed in my eyes.
- You're gonna - tell me the story,
- and you're gonna - tell me the truth.
Surprised to see me?
- Only surprised that - it's taken you this long.
(BREATHING HEAVILY)
How'd you find us?
The vials in the clinic
- with the Celtic - symbols on 'em.
- I knew that one of - 'em looked familiar.
Sheriff, thank you
for being one
hell of a detective.
- You bet. Let's get - you an ambulance.
Your eyes were red.
Bright red.
How is that possible?
- STILINSKI: Paramedics - are on their way.
- I'll be back - in half a minute.
It's rare.
- It's something that doesn't - happen within 100 years,
but every once in a while,
a Beta can become an Alpha
- without having to - steal or take that power.
They call it a true Alpha.
It's one who rises purely on
the strength of character,
- by virtue, - by sheer force of will.
You knew this would happen.
I believed.
- From the moment I knew - you were bitten, I believed.
You're not the only one.
No.
Deucalion isn't after Derek.
He's after you.
