Previously on Grimm...
They said you were dead. I think I was.
I hope that stick does what we think it does.
It's healing her!
I'm being haunted.
I believe they're going to kill you.
Two men waiting by your car.
This time, you chose the right side, Sean.
Two dimensions exist simultaneously,
one where the cat is alive, one where it's dead.
As long as the box stays closed, both realities exist-
- Eve! Nick! - Diana.
Mommy, it worked. I got Nick back for you.
I think part of you stayed in the other place.
She's not a Hexenbiest anymore.
No!
Wu, come on.
Wu, wake up, now, Wu.
This'll bring you back. All right?
It worked on me.
Come on!
Wu, come on! Come on, Wu.
Come on. Come on, man.
Hank! Come on! Come on! This has to work.
Come on, Hank, you're not gonna die. You can't die!
Please, please, Hank, come on.
Why isn't this working?
God!
Oh, God.
Nick!
They're dead.
Oh, my God.
Oh, my God, Nick.
Did you... It's not working.
No, they can't be dead!
Oh, my God! He killed everybody.
Except me, and I don't know why.
Maybe he thought you were dead,
or maybe the stick protected you.
Well, if the stick protected me,
why didn't it do anything to help Hank or Wu?
Didn't anybody shoot this thing?
We all did, it didn't make any difference.
Nick, we have to find out how to stop him.
I'm not gonna have any more cops killed.
I'm gonna find him and I'm gonna kill him.
If bullets won't kill him, we have to do this the way our ancestors did.
Cut off his head.
The weapon's still in the Spice Shop?
I have to warn Adalind first.
It's Nick.
- Nick? - Where's Renard?
He's right here.
He needs to hear this, but I don't want Diana to.
She's asleep. We're upstairs. What happened?
Zerstörer hit the precinct.
What?
He killed everyone who was inside.
Everyone?
Including Hank and Wu.
Oh, my God, Nick, no.
Where were you?
I was with them.
I was the only one he didn't kill... Couldn't kill... I don't know.
Bullets don't have any effect on him.
I still have the stick, maybe that's why I'm not dead.
I tried to use it on Wu and Hank, but it didn't do anything.
Nick, Diana said that this thing doesn't just want her,
it also wants Kelly.
No.
We have to stop him.
We're doing everything we can. Trubel's with me.
Thank God.
I'm gonna send her after you. What?
If he finds them, I need one of us with them.
Okay-
I'm going to the Spice Shop, I'll check in with you from there.
Please be careful.
You, too.
Here, take my car.
I don't think we should split up.
I need you out there.
What if...
What if, what?
I'm afraid to even say it, but what if Zerstörer really is unstoppable?
You mean unkillable?
I mean un-whatever it takes to get rid of him.
We don't know if he's a devil, some dark force of the universe,
or just evil incarnate.
Everything has a beginning and an end.
Well, I'm not finding any beginning or end
to whatever Zerstörer is.
"Strength of One's Blood" mean anything to anybody?
No, why?
Well, there's a reference to it here,
maybe sort of an Achilles' heel type of thing?
Specifically for Zerstörer?
No, it's more generically in reference to unstoppable evil,
Zerstörer-like dark forces of the universe
that precipitate apocalyptic events.
"When the beast appears invincible
"and death the only fate to those who fight it,"
"only the strength of one's blood"
"can overcome the great evil and destroy the destroyer."
"Strength of One's Blood."
There are a ton of blood spells in this book.
It's how I got through the mirror.
I think I know of one.
It's a potion. Force do sang.
It's in one of my parents' books.
It's really difficult to make though, it takes a ton of time,
has quite a few ingredients,
and is almost impossible to do
because it requires the blood of three opposing forces,
a Grimm, a Wesen, and a Hexenbiest.
Well, yeah.
I mean, that would be next to impossible,
considering a Grimm will kill any Wesen who asks for its blood,
and a Hexenbiest will pretty much kill anything for any reason.
But not for us.
You really think it'll work?
I have no idea, but it's definitely a "last resort" kind of potion.
Maybe it's just what we need to defeat this evil bastard.
Well, we're gonna have to ask Adalind
because my blood won't work anymore.
I'll text Nick.
Dude, we are taking you down.
That's enough.
Okay, now.
Nick, back here.
We may be onto something that might put an end to Zerstörer.
Yeah, it's sort of an Achilles' heel deal.
It's called force do sang.
It's referenced in one of the books as "Strength of One's Blood."
We're gonna need your blood.
What's wrong?
It hit the precinct.
We tried to fight it, but it killed everyone.
What do you mean, everyone?
Hank. Wu.
What? Oh, my God!
Hank and Wu are gone?
Yeah.
I can't believe it.
Trubel showed up after. I sent her to the cabin.
What do you need my blood for?
We need the blood of a Grimm, a Wesen,
and a Hexenbiest for this to work.
They all need to be mixed at the same time.
We have to go to Adalind.
Nick, it's the strongest poison I know of.
Yeah, supposedly, just this side of nuclear.
Let's do it! All right.
I just need a few more minutes to get it ready to go.
This better work,
'cause I don't know how I'm gonna get
close enough to him to cut his head off.
Hey, get me a thermos.
I wonder who was collecting all of these.
If I remember, it was a postman.
Blutbaden, old school.
Look, I want to tell you something.
Now, we've both made a lot of mistakes.
Too many.
But we did one thing right.
Diana.
I'm sorry for a lot of that stuff.
Me, too.
I wish I'd never heard of those damn keys, or Black Claw.
Or Bonaparte. Or this.
Am I ever gonna be able to take this damn thing off?
You never tried after Bonaparte died?
He said that great harm would come
to my children if I ever took it off.
I don't want to take that chance.
I will do everything in my power to protect Diana and Kelly.
I know you will.
It's Trubel.
Trubel!
You're supposed to be on our side now?
A lot has changed.
Yeah, I know.
I wish Meisner knew.
Trust me, he does.
I'll be outside. If he shows, you'll know.
Question, once it's ready, how do we get it on Zerstörer?
What about dipping bullets in it?
Like we did with the Siegbarste?
Remember, we shot him with that poison and it worked.
I still have the gun.
Maybe we should bring it. I'll get it.
Take your own car.
Once this is ready, you don't need to be there.
I'll ride with Nick.
I wish I hadn't lost what I was.
I'm sorry my blood is no good for this, we could've made it here.
I thought you weren't gonna do that anymore.
Do what?
Regret what's done.
I have no regrets, and I am definitely not done.
That I know.
Nick, go, they need your blood!
No!
Go!
Eve.
Juliette.
No regrets.
Come on. Come on. Not you. Not you.
Oh, God!
Where are you?
Come back and fight!
God damn you!
Come on!
You alone? Yeah.
But Nick and Eve should be pretty close behind us.
He tell you about Hank and Wu?
I can't believe it. I don't think I ever will.
You brought food?
We found something that might work on Zerstörer.
What?
We need to talk to Adalind.
She's inside.
What happened?
We found something in one of the books
referenced as "Strength of One's Blood."
Have you ever heard of force do sang?
"Power of blood"?
Yeah, I have, but, I mean, that's pretty impossible, isn't it?
It's definitely not easy.
We're praying it'll work against Zerstörer.
Okay, but doesn't it need a Wesen,
Hexenbiest, and a Grimm's blood?
Yes, Nick should be here soon. We'll just start getting it ready.
Okay-
That's his place.
What's happening?
I can't guarantee what'll happen if I go any closer.
It's too dangerous.
But there's nothing more I can do. I'm out of here.
Hey. Where's Eve?
No.
Let's go.
Nick's here.
Oh, God, I'm glad you're back. It's just awful about Hank and Wu.
- They didn't deserve that. - None of 'em did.
Where's Eve?
Zerstörer hit the Spice Shop just after you left.
Oh, God. He killed her.
Oh, God.
This can't be happening.
He let you live again?
It's gotta be the stick.
I don't know how else to explain it.
I tried to use it on her, it didn't work.
This Will.
Okay, the knife has to go through all of our hands together.
Then what?
Then we pull it out,
and all of our blood flows together into the bowl.
It can't be one of the three of us.
I can't.
I can.
Now, we Woge.
DO it!
Keep it together!
Okay-
That's enough blood.
I like that part of the spell.
I've never seen that before.
Hope that's what happens to Zerstörer.
Mommy.
Is everything all right, honey?
I feel different and I can't sleep.
There's no need to be scared, sweetie.
I'm not anymore.
Well, good. Because we have something
that'll take care of him once and for all.
Oh, so you know he's coming here.
What?
He knows where Nick is.
How?
The stick tells him.
Oh, my God! That's how he knows where you are, Nick.
And he wants it, Nick. He's been looking for it for a very long time.
Diana?
Diana!
No. No!
No, Diana!
Take Kelly and get out of here.
Nick, you need me! Save him!
Trubel, please!
Okay, you should go with Trubel.
I am not leaving you, and don't you dare argue with me!
Don't hurt him. He wants me to be with him.
Honey, you don't know what you're talking about.
He needs me!
I'll die before I let you have her.
I know.
Monroe, get the bowl.
- But don't spill anything! - Don't get it on you!
Okay-
Oh, my God.
Diana.
It's working!
I'm not taking any chances.
Oh, crap!
Trubel! Run!
Monroe!
Adalind.
Save Kelly and Diana.
No. No.
Monroe. Monroe.
No, you can't.
You can't.
No!
Stay away from my brother.
Diana...
You son of a bitch!
Kelly!
We're ready.
My brother likes you, too.
You've taken everything from me, you're not gonna take my son.
That doesn't need to happen.
None of this does.
The stick is what you want.
It is.
You can't kill me as long as I have it.
I'm willing to give you something in exchange for it.
I'm not interested.
You will be.
Trubel!
Trubel...
Nick! Did We kill him?
No.
Then why are we alive?
I can give them all back to you.
What the hell is going on?
You can have it.
No, Nick!
You can't give it to this lying son-of-a-bitch-devil!
If he wants the stick so bad, why doesn't he just take it?
Why's he asking when he can just take it from you?
What is he not telling you?
You might want to ask your children what to do.
Nick, you can't give it to him.
I want the people I love to live again.
Take it!
No, Nick! Nick, no!
Don't! Nick!
I understand what you want, but this will be the end of humanity.
This isn't about us, or the ones we love.
I can't let you do this.
Get out of my way!
No.
Nick! Nick, please don't do this.
No!
Nick! Nick.
You must not... You cannot betray us.
And what we are.
Stop. You must stop.
KELLY; Nick. Nicky!
Mom?
You can't do what you want to do.
How are you here?
Don't give away what you hold.
They're all dead. I have no choice!
AUNT MARIE; Nick.
Aunt Marie.
What you think you have to do is not what must be done.
Trubel is right.
He can't take it from you, it has to be given to him.
That is why he has taken everyone you loved, Nick.
So that you will give him what he wants.
If you do this,
you will sacrifice the world to endless pain and suffering.
The world you saw in the other place.
I want my friends back.
I want Adalind, and Diana... I want my son!
I want 'em all back.
You can defeat him.
I tried, I can't!
You can. You can.
With the Strength of One's Blood!
We tried that! You didn't.
The strength of your blood, the blood of your Grimm ancestors, all of us!
It's inside you.
It's what's makes us who we are.
Trubel, too.
The strength we need, that we all need, comes from our family.
It's where we've always found the way and the will to fight.
And with that, we can defeat any evil.
Together.
Nick!
This is what you killed everyone to get.
Give it to me.
Come and get it.
No.
You wanted it?
Here it is.
How'd you know I needed you?
We feel it.
Why do you think Theresa came back?
She felt it, too.
We are all descendants of the first Grimm.
That stick you found, the one our Grimm ancestors buried,
is part of a much greater power.
Guard it well.
You kept me from doing something terrible.
We helped you find your strength.
Take good care of my grandson.
I like his name.
I can't believe we did it.
The two of us taking this thing down.
The two of us? What are you talking about?
Me and you, who else?
But I did nothing for them.
Nick! Where did they go?
Who?
The other Grimms fighting with you.
Oh, my God.
I can bring them all back to life.
What are you talking about?
If it worked for you, it can work for them.
Nick, something's happening.
No way!
Nick... No!
Nick, no!
Nick! Nick, no!
Nick, no!
- Eve! - Nick?
Nick? I don't believe it!
Are you okay?
Mommy, it worked. I got Nick back for you.
Thank God you're okay.
You're alive.
Yeah, so are you.
Oh, my God. You're all alive.
What happened?
Eve! You're okay!
You're okay.
Yeah.
You're all okay.
Even you. Yeah.
We're fine.
It's you two we're worried about.
Oh, my God, we're too late.
Rosalee!
Nick!
Hank, you're okay!
Wait, you're okay?
And you!
Oh, God. Oh, God!
Yeah. Why, wasn't I?
- Trubel! - Trubel!
What're you doing here? Oh, my God!
I've been looking for you guys everywhere.
Trubel.
I had a feeling something bad was gonna happen.
But I guess it didn't.
What?
You're a Hexenbiest again.
Again?
Nick, he didn't come back through.
No, he didn't.
He's dead, and I'm not afraid anymore.
Neither am I.
Kelly! Where's Kelly?
Hey!
I'm so glad you're all here.
Nick, are you all right?
What's wrong?
I thought you were all...
Nick?
I'm just so thankful you're all here.
I know this ain't gonna make a lot of sense,
but when I was in the other place,
I didn't know if I'd ever get back.
And I felt what it would be like to lose all of you,
everyone I ever loved,
and anyone who ever meant anything to me, my family.
We thought we had lost you, too, man.
Come here.
We did it!
Uh, Nick?
Where did this come from?
He didn't know what to tell them.
But this time Zerstörer did not come through the mirror
anywhere in the world.
Because in the final epic battle
with the terrible beast from the other place,
Nick Burkhardt discovered that the only way to defeat such evil
was with the Strength of his Blood,
his Aunt Marie, his mother Kelly,
and Trubel, his third cousin on his mother's side.
The power of our ancestors.
And though the people of our world would never know
how close they had come to Hell on Earth,
we knew.
Because he never turned away from who he was, a Grimm,
and for that reason the world was changed.
Some will say it's just a myth, legend, or fairy tale,
but I know it's true because my father told me so.
Kelly, come on. I'm almost done.
Let's go.
Diana! Hurry up.
I'm coming!
Mom and Dad are waiting.
We've got Wesen to kill. The triplets are coming, too.
Yeah?
What's taking you so long?
