- SCOTT: Previously on - Teen Wolf...
- SCOTT: The mark of - a family of hunters...
The Calaveras.
- LYDIA: What would - they want with Derek?
STILES: How do we find them?
SCOTT: Mexico.
- You don't know - where he is either.
(GROANING)
- ARAYA: - You know who took him.
(ELECTRICITY CRACKLING)
Say the name, Scott.
- SCOTT: Kate. - Is that Derek?
SCOTT: Sort of.
(PEOPLE CHEERING)
(ALL SHOUTING EXCITEDLY)
BOY: Go. Hey, let's go.
(GROWLING)
I thought
I could control it.
All this risk?
Just for a
basketball game?
- It's the finals. - They need me.
To do what?
Rip someone's throat
out on the court?
- Even born wolves - have to learn control
on a full moon, Derek.
- Yeah, but it's supposed - to be easier for us.
- Why does it - hurt like this?
- PETER: - Did you bring it?
- It's not working... - Did you bring it?
PETER: Go ahead.
(PANTING)
- I told you, - it's not working.
Do it!
Alpha, Beta, Omega...
Again.
Alpha, Beta, Omega...
Again.
Alpha, Beta, Omega...
Again!
- (ECHOING) - Alpha, Beta, Omega...
Alpha, Beta, Omega...
(SCREAMING)
(LOUD HISSING)
(GROWLING)
Hey!
(BANGING ON DOOR)
You okay in there?
(PANTING)
Ahhh!
ATTENDANT: Hey, you all right?
- What's going - on in there?
(GROWLING CONTINUES)
- (EXHALES SHARPLY) - Just a second.
Hey!
I'll be out in a minute!
(GROWLING)
(BANGING ON DOOR)
- You need to - open the door.
- I don't know what - the hell you're doing
- or whatever you're on, - but I got a key.
- You come out - or I'm coming in.
Hey!
- You want me to - call the cops?
You hear me?
Lady, open the door!
Open it!
You okay?
(ROARING)
(MUSIC PLAYING)
Wow.
Wow? Wow as in,
- "I've seen this before - and I know exactly what
to do," kind of wow?
- 'Cause that's the kind of wow - we were hoping for.
- I think you might - be overestimating
my abilities.
LYDIA: He's cold.
Really cold.
- Do you think - this is permanent?
- I'm not sure a medical - diagnosis is even adequate.
- This is well beyond - my experience.
- So what do we do with him? - DEATON: Until he wakes up?
Probably not much.
It might be best
to leave him with me.
He'll be safe here.
You mean from Kate?
- If she's alive and she is - what you say she is,
- she won't be able to - walk past that gate.
- Why would she - want do this to him?
DEATON: Knowing Kate,
- it's probably for - a reason that won't be
- any good for - anyone but her.
- (SCOFFS) And bad - for everyone else.
- DEATON: You guys - should probably go home.
- He doesn't look - to be in any danger.
- So maybe the rest of you - should get some sleep?
It is a school night.
And you all need to
start taking care of
your own lives again.
- Someone should - stay with you.
I'll stay.
My grades are fine.
- Despite missing - a few classes.
- I'm so not - okay with this.
Guys, go.
No.
- Text us if - anything happens.
- Nope, still not - okay with it.
- Not going anywhere. - All right, just 'cause
you're stronger...
(WATER DRIPPING)
(CLATTERING)
Scott?
Hey, Dad.
What's with the tools?
Oh, I was just, uh,
getting started
on a list of repairs
you guys need done.
- What time is it? - It's, um,
- midnight. - We were supposed
to have dinner.
We had a deal.
When your mom
has a night shift,
we have dinner.
- Sorry, I totally - forgot about it.
- When we got back - from the camping trip,
- I had to go straight - to the animal clinic
to finish up work.
All right, well...
- (SIGHS) - Tomorrow night.
- Dinner. - Great.
- Did you get - anything to eat?
- (EXHALES) - Yeah, Mexican.
How's he doing?
- His heart rate - is alarmingly high.
- LYDIA: - He's a lot warmer now.
Lydia, I'm going
to try something.
- I want you to keep holding - his hand, if that's okay.
LYDIA: That
- looks like - it healed really fast.
Unusually fast.
What does it mean?
I'm not sure.
Let's try something else.
- Grab me a five-milliliter - syringe. Top drawer.
- LYDIA: Derek. - DEATON: Derek?
Derek, are you all right?
(MUFFLED) Derek.
- Derek... Derek? - DEATON: Are you
all right, Derek?
Wait.
LYDIA: (ECHOING)
Derek? Derek?
Derek?
(GROANS)
- DEATON: Can you hear me? - You're safe.
LYDIA: Derek?
Derek?
- So it's, like, 2:00 - in the morning.
I wake up and
she's just lying
right next to me.
- She just sneaks in. - This was, like,
five times a week.
- And then - what happens?
This...
- Holy... - Yeah. Right on, right?
- After that, we spent - the rest of the night
spooning.
That sounds okay.
- Yeah, but I'm always - the little spoon. Always.
- This means you guys - are together, right?
You're dating?
- I don't know, - sometimes the way
she looks at me,
- I think she knows - I'm not telling
her something.
- You mean Peter? - We got to
tell her, Scott.
Yeah, I know.
I just...
I don't know how.
- MR. YUKIMURA: It might - surprise you to know
- that some of history's - greatest leaders
have had to endure
some pretty great failures.
- One you'll recognize - from last night's reading
failed in business,
had a nervous breakdown,
- was defeated for both - houses of Congress,
and lost as
Vice President,
- before he was finally - elected
- as one of the greatest - presidents that this country
has ever seen.
Who was he?
Malia.
(RINGING)
Scott, phones off.
Malia? One of our
greatest presidents.
Gettysburg Address?
(CELLPHONE CHIMES)
Phones off. Everyone.
Malia?
Does anyone else know?
(CELLPHONE BEEPING)
I said, phones off!
Dad, that was yours.
Oh. Um...
"Scott, call Lydia."
- I don't think he's - just younger in body.
- I think he's younger - in his mind, too.
- He didn't recognize - either of us.
- And he looked - like he was scared
out of his mind.
- STILES: So if you're a teenage - werewolf and you're scared,
where do you go?
- A wolf goes back to its den. - But Derek lives in a loft.
- Not when he - was a teenager.
The Hale House?
- DEATON: He wouldn't - remember the fire.
- It wouldn't have - happened yet.
LYDIA: Hold on.
- Say you do manage - to catch up to him,
- what are you going - to say to him?
- That his whole - family is dead?
- I guess I'm going - to have to.
Oh.
Good luck with that.
- She's probably right. - Maybe you shouldn't.
- You know, at least until - we figure out how to
get him back to normal.
- I can't lie to him. - Okay, I'll do it.
I don't think any of us can.
- Remember, he can hear - a heartbeat rising.
- When we find him, - we tell him the truth.
- If he gets to - the house first,
you won't have to.
Excuse me,
young man?
- You're calling - him young man?
Shut up, Haige.
Sorry, but you
can't be here.
Hey, dumbass.
You ever hear of
"no trespassing"?
This is my house.
- Nobody's been - here for years, kid.
- Now get the - hell out of here.
Haige,
- maybe a slightly - gentler touch?
Are you all right?
- We can help you - if something's wrong.
- What happened - to my house?
- Where's my family? - Where's my mother?
All right, let's go. Now.
(GROANING)
Hold on, just take it easy.
- Haige, would you... - Don't... Wait!
(GROANING)
Haige!
- Haige, - stand down!
(GROWLS)
(SIGHS)
- The other deputy thinks - I'm an idiot for even asking,
- but I have a feeling - if I take these cuffs off,
you're going to be okay?
- And I think you'll - help us figure out what
happened to your family
- so we can - get you out of here.
Am I right?
(UNSHACKLING)
The other deputy's the idiot.
I can't argue with that.
Parrish, get over here.
- I ran this kid's - prints eight times.
This is all that comes up.
PARRISH: Derek Hale?
Did you say "Hale"?
(EXHALES)
I'll handle this.
- STILINSKI: I want you - to be honest with me.
Absolutely and
completely honest.
- Have you been - time traveling?
Hang on, what?
- Because if time - traveling is real,
- you know what, - I'm done, I'm out.
- You're going to - be driving me
to Eichen House.
We found him like that.
- Where? Swimming in - the Fountain of Youth?
- No. We found him buried - in a tomb of wolfsbane
- in an Aztec temple in - Mexico underneath a church
- in the middle of a town - that was destroyed
by an earthquake.
You told me you were camping!
Yeah, we were.
In Mexico.
- Derek's been aged backwards. - He can't remember anything.
- We just need - to talk to him.
Yeah, well, so far
- he's not talking - to anybody.
(SIGHS)
He'll talk to me.
- Why would I go - anywhere with you?
There was an accident.
- You lost some memory, - but we can help you
get it back.
DEREK: How much memory?
A lot. But you can trust us.
You're an Alpha.
- DEREK: - Okay, who are you?
- And who is he? - Who are you?
- Oh, we're the guys - keeping you out of jail.
SCOTT: Let us help you.
No.
Okay, dude, you almost
tore apart two cops
back there.
- You need - to listen to us.
- And that starts with - no fangs, no claws,
- no wolf man. - You got that?
- I'm fine as long as - it's not on a full moon.
- You still have trouble - with the full moon?
I said I'm fine.
- All right, you coming - with us or not?
You want me to trust you?
Where's my family?
(SIGHS)
There was a fire.
And...
- They're not here anymore. - They're fine.
- Just had to move - out of Beacon Hills.
- And we're going - to take you to them
- as soon as we - figure out how to get
your memories back.
(EXHALES)
Okay.
I shouldn't have done that.
I lied my ass off.
Hey, your ass is fine.
- You saved him a ton - of unnecessary pain.
- We'll figure this - out in a day or two,
- he goes back - to being old Derek,
everyone's happy.
- Except for Derek, - who's never happy.
- It's just another person - that we're lying to.
- Just that I always feel - like it's better when
we tell the truth.
- With Lydia, - my mom, your dad.
- But that is - Derek Hale in there.
- He may be a kid right now, - but he's still Derek Hale.
- SCOTT: All right. - Take him to my house
- and don't let him - out of your sight.
And where are
you going?
- I'm going to go talk - to the guy we should
have gone to before.
Uh...
Yeah, I hate that guy.
♪ Run away, run away
♪ Let's take tomorrow ♪
Scott's going to find Peter.
- And we're supposed to meet - Stiles at Scott's house.
- That sounds - like a horrible plan.
But we've had worse.
Like yesterday in Mexico?
About that.
- Remember - how we were in the club
- and you and Scott - were tied up to
electrified cables?
Vividly.
I know.
- I guess what - I'm trying to ask is,
- if my hand was on - the dial connected to you
- and I had to - turn it up to 10...
Would I be angry?
Yeah.
No.
- Because I knew - you had no choice.
- Exactly like - Scott knows.
- And if you're - worried about him,
just remember,
- you're a katana-wielding, - badass kitsune.
(CHUCKLES)
- And he couldn't - be more into you.
(DOOR OPENS)
- Grab a card from - the visor so we can fill up.
- Uh, Beacon Hills - Credit Union.
- Does this many cards mean - you have good credit or bad?
- Hey, it looks - like you have
a full tank.
Lydia?
Are you okay? Lydia?
Don't look.
What are you doing here?
- I heard you were - coming to talk to Peter.
- And since Lydia - tells me he's basically
Satan in a V-neck,
- I figured you - shouldn't be alone.
I can handle Peter.
- You can handle - him better with me.
- We're going to wait here - for Scott. We're going
to sit quietly.
- And we're not going to - call or talk to anyone.
Do I talk to you?
- No. Fine. - Good.
- Who's going - to talk to him?
Ah! Are you getting taller?
- What are you - guys doing here?
Waiting for Scott.
Yeah, so am I.
We're supposed
to have dinner.
- I brought extra. - You guys hungry?
- Yeah. - No. We're not hungry.
- No, I'm starving. - Neither of us are hungry.
Thanks, though.
- Okay, well, if you're - not hungry, Stiles,
- your friend can - still eat with us.
- What's your name? - Miguel.
- (STUTTERING) - My cousin Miguel.
From Mexico. So...
(SPEAKING SPANISH)
Oh, my God.
(SPEAKING SPANISH)
Fantastic. Egg roll?
- Hell, yeah. - (LAUGHS NERVOUSLY)
- Shrimp fried rice - or pork fried rice?
Shrimp fried rice.
- Fantastic! - Egg roll.
Beef and broccoli.
What's wrong
with you?
Nothing.
Your heart is
pounding like crazy.
Are you nervous?
- He's just bad - at introductions.
Peter.
This is Malia.
PETER: Beautiful eyes.
- Did you get them - from your father?
Mother.
PETER: Interesting.
Anyway, I'm sure
they've told you
a lot about me.
- The homicidal - killing spree came up.
- Well, we're all - works in progress.
- Well, when you - progress to your
next killing spree,
- why don't you - try and make sure
they all stay dead?
- What is that - supposed to mean?
- What do you know about people - being turned by a scratch?
- Did you scratch - someone, Scott?
Don't worry about it,
the claws have
to go pretty deep.
But it's possible.
Like if you clawed out
someone's throat?
Well, yeah,
it's possible.
- It's also beyond rare. - I mean, we're talking
one in a
million.
So, uh, Miguel,
- what did you - say your last
name was again?
Oh, it's Juarez
Cinqua Tiago.
That's a mouthful.
How do you spell that?
Phonetically.
- Mr. McCall, - you're an FBI Agent?
He's low level.
Very low level.
- He doesn't even - have a voice.
- So do you - investigate murders?
- Sometimes. When - it's a federal crime.
What about fires?
- STILES: Oh, my God. - I wonder where Scott is.
- Shouldn't Scott - be here by now?
We should call Scott.
- What kind of fires - are you talking about?
(NERVOUS LAUGH)
- Do you know anything - about the Hale family?
Can't someone in
this town stay dead?
I think they were
hoping you would.
- Do you have any idea - why Kate would turn Derek
into a teenager again?
What color were his eyes?
Blue.
After Paige.
- Which could mean - around the time
he first met Kate.
- Derek and Kate - knew each other?
Biblically.
That's right, Scott.
- You weren't - the first wolf to climb
into a hunter's bed.
Okay, I didn't lie.
I omitted certain truths.
- Vital truths now - that I think about it.
- I don't want to - talk to you.
- I want to talk - to the Alpha.
I'll talk to Scott.
- Okay. I'm going - to go get him.
- My phone's downstairs. - Going to call him real quick.
- You stay here. - Just don't move, okay?
Don't move.
Don't...
I thought you...
Okay, Derek went to the site
of the house thinking that
it was still there, right?
- Yeah. But he doesn't - remember the fire.
But if he doesn't remember the
fire, then he doesn't remember
that it was Kate that set it.
So what does that mean?
- Kate didn't just take him - back to being a teenager.
- She took him - back to the age
where he still knew her.
When he still trusted her.
(DOOR CREAKS)
Kate?
Hey, handsome.
Been a long time.
(CHUCKLES)
Longer than you think.
- No, he's in your bedroom, - he'll be totally fine.
- To be honest, - I'm starting to miss
the old Derek.
- So, if you actually - think that Kate's
coming to find him...
You might be right.
Wait.
For what?
- Kate's out there - twisting her way into
Derek's head yet again.
We need to find her.
All we need's a scent.
- That could take hours. - If we want to
get ahead of her,
- we need to figure out - where she's going.
- Not to underestimate - my own cognitive faculties,
- but we're not exactly - a brain trust of
geniuses here.
- Then maybe we - should call one.
(FLIES BUZZING)
- We called Stilinski. - They're on their way.
- SCOTT: What does it look like? - Can you send pictures?
Uh, okay.
(CLEARS THROAT)
- To be honest, - I have a 4.0 in AP Biology,
and there are parts
of the human anatomy
- I have never seen before - on these walls.
(BOTH QUIVERING)
(BEEPING)
(CHIMES)
- Why would she want to kill - a gas station attendant?
- I don't think she could help - it. This was done in a frenzy.
It's not a murder.
- It's a symptom. - Of what?
She can't control the shift.
- Derek said he had the same - issue on the full moon.
That he was still learning.
Kate's still learning?
She wants to learn.
- So she wants Derek - to teach her?
No.
She wants the Triskelion.
What's wrong?
I don't know
about this.
- I'm not supposed to show - the vault to anyone
outside my family.
Come on,
we talked
about this.
- Yeah, but how - do you even know?
Because you told me.
Don't you remember?
- Tell me - if you remember this.
We get inside the vault.
We get the Triskelion.
- And then everything - goes back to normal.
That's all you want?
That's all we need.
- But right now, we have to - get inside that vault.
DEREK: Over here.
- Why would your - family build a vault
under a high school?
- The vault - was here first.
Did you catch a scent?
It's the same one.
The same one as Mexico.
What is she talking about?
- One of them came after - us in the Church ruins.
And one on the road.
- They couldn't have - followed us here.
- But they could've - been brought by Kate.
(GROWLING)
- Oh, I've heard - that sound before.
- Did it have - an animal skull?
- A human wearing - a skull over its face?
I think so.
What are they?
(GROWLING)
Berserkers.
Are you crazy?
There's just one of them.
- And that means - we have a chance.
To beat him?
To survive.
Not that.
(GROWLING)
- Scott. It's both of them. - They're both here.
Where the hell's Peter?
- I don't know. - He just took off.
KATE: This is it?
You're sure?
Yeah.
It doesn't look like much.
PETER: That's 'cause it isn't.
- Quite the elaborate scheme - you have here, Kate.
Two countries, Aztec temples,
Derek returned to a teenager.
One that trusted you.
One that loved you.
- All this complication just - to gain access to our vault.
- Just to get your hands on - that little piece of junk.
Turn it over.
Go ahead.
- There's a scrape - on the back
- where it used to say - "Made in China."
You're lying.
I admit I have
a tendency to
exaggerate things.
But in this case
the truth is
so much more fun.
Oh, I'm sorry,
sweetheart,
that little pendant
is just a physical
object to focus on.
It's training wheels.
Talia used it
to teach Laura.
- I tried to use it - to teach Derek.
(LOUD ROARING)
(GROWLING)
- Is this real? - Tell me if this is real.
- Didn't you hear that? - That was Scott.
I just heard Scott...
Tell me!
- I don't know, - and I don't care!
(PANTING)
- You seriously need - to find something better
than a baseball bat.
Kira!
Derek gave up on it
- back when - he learned another way
to control the shift.
When I taught him.
Concentrate.
- I taught him to use emotion, - to use anger,
and to focus on it.
To feel every ounce
of rage and hatred
that he could summon,
- and it was the anger - that taught him control.
- So you want to learn - to control it?
- You want to get - angry, Kate?
Let's get angry!
(GROANS)
(COUGHING)
(LOUD SCREECH)
- (ECHOING) - Wait!
Wait!
(GROANS)
Derek?
It was never
about the Triskelion.
(MUTTERING)
They took it
while I was blinded.
Took what?
Bonds.
- Bearer bonds - and they took them all.
- Bearer bonds? Hold on. - Hold on. Are you saying
you got robbed?
This was a heist.
Somebody planned this.
How much did they take?
Hundred-and-seventeen.
Thousand?
Million.
