- LYDIA: - Previously on Teen Wolf...
GERARD: The name
Sebastien Valet
has been forgotten.
- COREY: They took - him and I couldn't
do anything.
We can find him.
- SURGEON: True evil only - comes by corrupting
something truly good.
Mason!
(BEAST ROARS)
- SCOTT: Who the - hell was that?
Sebastien Valet.
(GROWLS)
(MUSIC PLAYING)
You knew, didn't you?
I wasn't certain,
but I suspected.
Although, it makes sense
that Marie-Jeanne's pike would
be reforged into something
- that could appear - as innocuous as a cane.
But will it kill him?
You're damn right it will.
- Vanishing - twin syndrome...
- This is part of your - expertise, right?
Not particularly, no.
(MUSIC PLAYING)
(DOOR OPENS)
He's still alive.
(TRACY GASPING)
(THEO GRUNTING)
(GRUNTS)
(PANTING)
This looks bad, Theo.
I'll be fine.
(MUSIC PLAYING)
(GROANS)
Maybe we need to stop.
Or figure out another plan.
- Just take a couple more - days to think about it.
Days? You want
to wait days?
- You're hurt. - You need time to heal.
And I'm not like the others.
I can't take your pain.
I know,
and that's okay.
- Because you can do - something else for me.
You can give me your power.
(YELLS)
(GROANS)
Theo...
(GRUNTING)
(SNARLING)
Theo, stop...
(GASPS)
(GRUNTING)
(GRUNTS)
And then there were none.

- DESERT WOLF: - Who are you calling, Malia?
Is it Stiles, your boyfriend?
Tell him to come.
Bring all your friends,
if you want.
Go ahead, Malia.
You tell me how many
people I'm going to
have to kill tonight.
(BEEPING)
- SCOTT: Can you - keep him alive?
- I'm not sure - he technically is alive.
- Screw keeping him alive. - How do we get him to talk?
- Personally, I don't think we - utilize torture nearly enough.
SEBASTIEN: Come...
Did you hear that?
SEBASTIEN: Come to me...
To me.
(HIGH-PITCHED NOISE)
(WINCING)
Liam, wait!
(GROANS)
DEATON: Stop.
It's electrified.
Marcel...
- If this is what - immortality looks like,
- I think you might - have been misled.
For you...
All for you...
- What did you do - with it, Marcel?
Where is the pike?
The Argents...
The cane.
But they took it.
They took the cane.
I lost him.
- Sebastien's going to - know we have the pike.
- And if he doesn't, - he's going to figure
it out soon enough.
Then what do we do?
We stop chasing him.
And make him come to us.
(GUNSHOT)
Almost, Braeden.
But not quite.
You'll get another chance.
- But you better make - sure it's a head shot.
Coming down, Malia?
Malia, don't move!
- Maybe there's - something in here.
- Something about how - he was a Genetic Chimera.
Mason had a vanishing twin.
- Now we've got - a vanishing Mason.
- What does that have to - do with him turning into
a 250-year-old French guy?
How does that even happen?
Hold on, Scott might
have something.
Mason's twin wasn't
entirely gone. That's what
made him a Genetic Chimera.
The DNA was still there.
Metaphorically speaking,
the DNA of Mason could still
be inside Sebastien as well.
How?
Life is energy.
Energy doesn't
just disappear.
- The Dread Doctors may have - found a way to break the rules
of the supernatural world
- but there are some rules - that simply won't break.
- So Mason can't - just be gone?
Somewhere in Sebastien
he has to still exist
in some form.
A spark of energy,
a flicker of memory.
Hang on...
- Liam, you said Mason - said something
right before he turned.
He said, "That's not my name."
- He finally - remembered his name.
Damnatio Memoriae.
That's what they wanted.
- They wanted Sebastien - to remember his name.
Scott, you know the
myth of what happens
when you call a werewolf
by its given name?
It turns back to human.
What does that mean?
- Someone can just - walk up to the Beast,
- yell Mason's name - and turn him back?
Not someone...
Lydia.
- Who did you say - you were looking for?
The man's name is Argent.
Did you say Argent?
Sorry. My son likes to
leave incredibly long and
incredibly confusing messages.
- Maybe I should just turn - the damn thing...
So...
- You're looking for - one of the Argents?
(SOUND OF HEART BEAT)
You seem to know who I am.
That means you know
what I'm capable of.
I've got some experience.
Your weapons may be
more sophisticated
than the arrows and
the bullets of my time,
but they still won't kill me.
- I'm pretty sure - a nine millimeter Beretta
will do more damage
than an 18th century musket.
Are you certain?
I can walk out
of this place
with my hands clean.
Or, I can walk out with
them drenched in blood.
Your choice.
(SOUND OF HEART BEAT)
Sir?
Clark, don't.
Stop where you are.
Let him go.
No!

(DRAMATIC MUSIC)
Melissa...
Melissa!
Malia. Come down.
Don't listen to her.
I'm not going to stop, Malia.
- I'm taking back what - you stole from me.
I didn't steal anything.
DESERT WOLF: But you did.
And I don't care if you were
a willing participant or not.
Talia Hale spent nine months
trying to convince me of
the miracle of childbirth.
- You know what it - really felt like?
A parasite.
Talia said it was a gift...
That the coyote passes
down part of her power
to her daughter.
She called it beautiful.
I call it theft.
(STAIRS CREAKING)
(GUNSHOTS)
(GLASS SHATTERING)
Where is it?
- I brought you here - like you wanted.
- How about letting - me go now?
- This demon, on the left. - What is he?
He's called a Hellhound.
Parrish... His name
is Parrish, isn't it?
- And the Argents will try to - put the pike in his hands.
When did young people
become so confident?
(SHRIEKS)
(GASPING)
(GROANS)
I know that sound.
It's the Argents, isn't it?
- Drawing the Beast - to them. Corralling it.
- You'll need to be - back at full capacity.
(DRAMATIC MUSIC)
Let's find out.
(ELECTRICITY CRACKLING)
(GASPING)
Looks like it worked.
You know, Theo,
someday your willingness
to stab anyone and everyone
in the back
might turn out to
be your downfall.
(LAUGHS)
- Don't worry. You can - still have Scott's eyes.
- I'll just be bringing - them to you.
Hey. You all right?
Did...
Did you find something?
A solution?
Yeah. It was you.
It was you, Lydia.
(GUN COCKING)
Lydia's been hurt. Badly.
(DISTANT GROWLING)
It doesn't change anything.
What if she's dying?
- If we don't stop - Sebastien, she will die.
- He's not just - coming for the pike.
- He's coming for anything - that stands in his way.
- Right now, - that's all of us.
(GROWLING AND POUNDING NOISE)
What are you doing?
You saved my life once.
Now, I'm going to save yours.
(POUNDING NOISE)
(GROWLING NOISE)
- I'm not sure I'm getting - the strategy here.
You're the strategy, Parrish.
- You're the one - in the fresco.
Put there as a reminder
that the Beast
isn't unstoppable.
Whoever painted it...
They didn't see a guy with
a gun facing down the Beast.
They saw you.
They saw a Hellhound.
(DRAMATIC MUSIC)
(MUSIC PLAYING)
Is she okay?
She's gonna be fine, but...
She can't really talk.
Then it's over, isn't it?
- There's nothing - we can do to save him.
(PHONE VIBRATING)
Give me a second.
- KIRA: Hey, it's me. Oh, God, - I wish you just picked up.
I hate leaving messages.
- I always ramble. - I always say stupid things
- and when I finally get - to the super important thing
- that I'm supposed to say, - the voicemail cuts
me off and...
(BEEPS)
KIRA: Me again.
I have to leave.
But I'm coming back
to help. I promise.
Because you're right, Scott.
If anyone's going to
save Mason, it's you.
- It's us. - (LINE DISCONNECTS)
(MUSIC PLAYING)
Get up.
Why?
Because I've got an idea.
And because this isn't over.
- (GROANING) - (DOOR OPENING)
(MUSIC PLAYING)
- Lydia, this is gonna have - to be just between us,
- since I can - get fired for it.
- It's a cortisone shot. - It's gonna bring
the inflammation down.
Not there.
(LYDIA GROANS)
- Oh, yeah, okay, - I'm gonna need to leave.
- You're not going - anywhere.
Hold her hand.
- Okay, fine. I'm not leaving, - but I still might faint.
- MELISSA: (SOFTLY) - Okay. Here we go.
(THUDDING)
- Okay, Lydia, this is - gonna hurt like a bitch.
- (WHIMPERING) - (MUSIC PLAYING)
(GASPING)
(ELEVATOR DINGS)
Okay. I'll get Malia.
- Text me when - you find Parrish.
Hold on.
- What is this? - Something I've been
working on for a while.
Just make sure
Malia gets it.
Is it plan B?
It was plan A.
Plan A never works.
- This one will. - Okay.
(DOOR OPENING)
Hayden?
(GASPING)
- They said that you can - help us when we get hurt.
- (GROANS) Well, I think - I'm pretty hurt.

It could have worked.
With Belasko's talons.
(LYDIA GASPING)
(STRAINING)
(MUSIC PLAYING)
You broke my neck.
And good luck with that.
- There's an access grate - that leads to the sublevel.
- I think we can - get to Lydia there.
What about Mason?
- We can still - save your friend.
Let's go.
(GUNSHOT)
(GRUNTS)
This just isn't my day.
This is a surprising
alliance, Scott.
You and Deucalion?
(DEUCALION GASPING)
How long have you been
planning this clever
little double cross?
- About as long as he and I - have been planning this one.
What are you doing?
- I knew when - I brought you back,
- it would never be - about saving lives.
- Only about - immortalizing your own.
Scott, go.

Go, now!

of glass out of my chest?
Please?

LIAM: Scott.
I'll do it.
Liam...
It should be me.
- If you get me - close enough, I'll do it.
- We're not killing - your best friend.
- SEBASTIEN: - That belongs to me.
It's a family heirloom.
I'd like it back, please.
- It's all yours. - Just give us Mason.
- Unfortunately, I would - not know where to begin.
- And while I've benefited - from his memories,
- I don't have much - use for an alter ego.
(SCOTT AND LIAM SNARLING)

Come and get it.

We can still save Mason.
Who's going to save you?

- Hayden, I've managed - to stabilize the injury.
- But considering - you're a Chimera,
I don't know how,
or if, you'll heal.
- We can still take you - to the hospital.
- I've already died - there once.
It's your choice.
I know.
(SNARLING)
(MUSIC PLAYING)
You saved their lives.
Mason. Malia.
Half the population
of Beacon Hills.
- That's got to feel - pretty good.
It did. For a while.
- But it's something - you want to feel again.
Yeah.
Yeah, I think so.
Welcome to
your future career
in law enforcement.
(MUSIC PLAYING)
- You don't have - to do this.
I made a deal
with them.
I need to.
- It's not for my parents. - It's not for you.
It's for me.
- How long is it - going to take?
As long as it takes.
Keep it for me.
Keep it safe.
- But she'll be back. - She still has to graduate.
- That's the thing, - though, I don't know...
- When we started - this school year,
- I was so stressed about - everyone ending up
- in the same place - after we graduate.
- But I don't think - it matters.
- We always seem to find - each other anyway.
Even Allison.
He didn't tell you.
It was in the tunnels...
When Sebastien had
his hands around
Scott's throat.
The guy probably
didn't even know
what he was doing.
- His claws got into - Scott's neck.
He was going
to kill him,
but then he stopped
and he said a name...
Marie-Jeanne.
He saw Scott's memories.
He saw Allison.
- LYDIA: They must have - looked like each other.
- I mean, maybe - exactly like each other.
- STILES: It gave Scott - a chance to break free.
She saved him.
Allison saved his life.
