Whoever's doing this is infected with blood rage.
Why would he be following Matthew and Diana?
The killer stole their portraits,
miniatures painted in the 16th century, nothing else was taken.
Now you're mated, blood rage is harder to control.
I want the infected vampire found, killed and the outbreak contained.
Vampires can no longer sire, witches' powers are waning.
Daemons seem to be slipping into actual mental illness.
We need a cure for blood rage.
I will give you my blood, but in a way Matthew will not pick up your scent.
He cannot know about our pact.
I will watch over the child.
Madam de Clermont. I'm Benjamin Fuchs.
Matthew, I think I met him. And he certainly didn't say he was your son.
He's not my son!
When did they get back?
I told you never to come back here.
Oh, I'll leave. When I get what I came for.
He is not here.
I haven't seen him for months.
I'm sure he'll turn up.
And when he does, you'll let me know, won't you?
Why can't you just leave him alone, Benjamin?
I'm sorry Matthew, but it's far more complex than we first imagined.
We've identified nearly a hundred vampire genes.
We still have over 400 to go.
This is a massive task.
You're a scientist, you know how this works.
You can't cut corners.
And Miriam is as brilliant as she is annoying.
-Thank you. -You're welcome.
-But there's still only two of us. -So then, the cure is...
Years away.
Well, then we need to work faster because Diana is pregnant.
And if the babies are infected, we'll need a cure.
Look, I understand, but it will take time.
And we're going to need more researchers.
If anyone can find answers, it's Miriam and Chris.
Yes, but we've got weeks. Not years.
What is it?
Vampires.
Matthew.
Diana Bishop.
Father Hubbard.
Why are you here?
London is my domain, until God calls us to Him.
But I've come looking for you.
Both of you.
You left something in my keeping.
Jack.
I've brought him back
where he belongs.
The plague came back to London.
I started shivering one morning, by dawn I was dying.
Father Hubbard made me a vampire.
I had to save his life.
Poor boy didn't know what he was choosing.
He was a young man, by this time, Matthew.
-Not the little boy you left behind. -Henry Percy, well provided for.
Did you really think a warm bed and food in his belly could mend his broken heart?
He went to the docks every day looking for ships from Europe,
hoping that you'd be aboard
or that someone would have some news of you.
In the end, I had to tell him you weren't coming back.
I am so sorry we left you.
He told me that you'd time walked back to this century.
You knew that?
You knew that in the 1590's?
I gave Hubbard a drop of my blood. So that he would protect Jack.
And he did.
I did.
He was your responsibility, Matthew.
You made him mine.
Get out.
Why are you so angry?
Because your blood could've revealed everything about you to Hubbard
and therefore, in turn, reveal all of my secrets too!
One drop was all he got. I used my magic.
He got some of my secrets, he won't have learned any of yours.
What did you expect him to do?
Hubbard couldn't let Jack die, could you?
I chose to die as a human, rather than live without my wife or son!
Do you wish you had?
No.
Because I would never have met you.
And now, I have a chance to be a father again.
That's exactly what Jack has.
Another chance to have a family. With us.
I remember finding this book.
In Bohemia.
An old grimoire.
Full of spells that worked.
Once.
When witches had real power.
I found something else.
A letter from Edward Kelley about the missing pages from the Book of Life.
Missing pages?
Three pages were torn out.
Kelley sent them to three different recipients.
Imagine if we could find those pages and reunite them with the Book.
We?
You want me to help you?
I gave you your place on the Congregation.
I owe you nothing.
You can't control me anymore.
I am a weaver.
Beware of the witch with the blood of the lion and of the wolf,
for she will destroy the children of the night.
And you thought Diana was that witch.
Satu, you must help me.
Your time is over.
Gerbert has no loyalty.
As soon as you cease to be useful to him, he will turn on you.
You and Gerbert are the same.
Men obsessed with power.
What's this?
It's the research Diana and I have been doing.
The last time she saw the Book of Life was in Blackfriars.
And she sent it to John Dee, so it could find its way to Elias Ashmole,
to the Bodleian.
Now, we know it's still there, somewhere,
but the pages Edward Kelley tore out are still lost.
And where's the best place to hide a page?
On your desk, by the looks of it.
In a book.
And Dee took some of his library to Europe.
And the rest, it stayed here, in England.
Over his lifetime, they were sold off, pilfered.
They ended up all over the world.
So, I've been tracking down the current locations
of all the magical and alchemical books.
So Diana can search through them.
I think Matthew's feeling guilty about Jack.
He's a 6th century patriarch.
Vampire families are held together with obedience and discipline.
Well, Diana's a 21st century witch. Something's going to have to change.
I have to go into the university with Diana.
Gallowglass and Fernando will stay with you.
Drawing helps me think.
Or stop thinking.
Why didn't you want me to become a vampire?
When I knew I was dying, my life just felt unfinished.
Maybe that's how everyone feels.
But I knew that I had a chance to find you again.
I'm so glad you're here, Jack.
We have an awful lot to catch up on.
Or we start again.
A clean slate.
We're not just understaffed.
We don't have enough DNA from your bloodline.
We only have three samples: Matthew, Marcus and Ysabeau.
And if you want us to establish a pedigree that can tell us
how blood rage is inherited, we're gonna need more.
Marcus should go to New Orleans.
-What's in New Orleans? -Marcus' children.
Vampire children?
I'll talk to Marcus.
Good, that will give me a chance to share what data we have with my team.
I'm sorry, you're team of teenage warmbloods, analyzing creature DNA?
-I don't think so. -Try students.
They need to know. And we need their help.
-It's too dangerous. -Matthew.
This is a huge task.
You want a cure for blood rage tomorrow,
but you only want two people working on it?
If our genetic information gets into the wrong hands, it will get us all killed,
if not worse.
-I understand. -No, you don't. You don't.
My father was captured by the Germans during the war
and experimented on
and tortured all in the name of medical science. I can assure you Chris,
you have no idea what your kind is capable of.
I'm a black man, from Alabama.
Believe me, I understand what humans are capable of.
Now, my team here are not the wrong hands.
You're not gonna be able to keep
the existence of creatures away from humans for much longer.
You're one autopsy, one genetic counselling session,
one home DNA-testing kit away from being outed.
Now, who do you want to have that information?
-Working alone will always limit us. -We've already trusted Chris.
I think it's time to trust others.
I was worried they wouldn't recognize me, but Diana knew right away.
-She's exactly like I remember. -Aye, she is that.
Baldwin.
Gallowglass.
I need to speak with Matthew and Diana.
I think they're inside the house Has something happened?
-Who the hell is this? -Jack Blackfriars.
Get out.
Now.
One of Hubbard's strays.
It's family only in this house.
Jack!
Baldwin. No.
Darling, I understand.
But conversing with students about creature genetics goes
against everything that has secured my survival.
It goes against the very reason that Philippe established the Covenant,
900 years ago.
Well, Philippe also said that the only reliable thing in the world is change.
Lychee?
What is it?
Matthew?
Jack attacked Baldwin!
A vampire you are concealing?
Jack, Jack, Jack. Calm down, calm down!
-Look at me. Look at me! -Tell him I belong to you!
I am the head of this family!
If you can't control your houseguest, I will.
Baldwin!
Take your hands off my son.
Let Jack go! Let him go.
Let him go!
Baldwin,
Jack belongs to us. I will deal with this. Do you understand?
Diana, please.
Diana.
Release him from your spell, now.
Stay away!
I drank his blood.
I saw his memories.
He is the blood raged killer.
This is his work!
The slaughter of warmbloods!
Jack?
Was this you?
Is it true?
And you were protecting him?
You know what has to be done.
Monsieur.
I promise you, I had no knowledge of Jack's blood rage.
Brother, this could ruin our family.
Kill him.
God help me.
Do it!
Please, Matthew, no!
Jack!
You aren't going to kill him.
Are you?
Look, Jack had begged me not to tell you.
And I hoped you wouldn't need to know.
If Jack is kept safe and happy, then the blood rage recedes, as you know.
How did he get it?
Was it from you?
Benjamin Fuchs is my sire.
Benjamin.
In 1349, I lost my whole parish to the plague.
I buried them all.
And then, I dug my own grave and lay down in it.
But I was brought back to life. Benjamin resurrected me.
He hoped that I would have blood rage.
He also hoped that I would stand with him against the de Clermonts
and their allies.
Why did you bring Jack to us? Now?
I hadn't heard from Benjamin for years.
But then he came,
looking for Jack.
Jack was young when I sired him.
He was malleable.
Benjamin saw this, he saw that Jack could be what I wouldn't.
And used his blood rage as a weapon against the de Clermonts.
So he forced Jack to kill,
to hunt for pleasure, to torture his victims.
He told Jack that he needed to prove
that he was really one of Matthew de Clermont's blood.
-And you couldn't stop him? -Oh, I tried, Diana.
But I have many lost souls in my flock to take care of.
I was Jack's sire, but I wasn't his father.
He promised me.
He says "I will not kill."
So many times, but...
-It was like an addiction. -It is an addiction.
If it isn't controlled, and Benjamin would have been far too strong for him.
You're my last hope for him, Matthew.
You can't kill Jack. He's our son.
We need to find him and help him.
Jack is in more suffering than you can possibly imagine.
I can end that suffering, give him peace.
And he's already put us all at risk.
Okay, this is ridiculous. Aren't the lab finding a cure for blood rage?
I mean isn't that why we were all dragged here?
And what if there is no cure?
We bring him home, we keep him safe until we find one.
And when the Congregation find out that Jack is guilty of the blood rage murders,
they will kill him.
Or Baldwin will kill him, or Benjamin will find him
and none of them will care how much pain they inflict upon our boy!
To save Jack,
I would have to disobey Baldwin.
The head of my family.
It's insanity.
This is a war that we cannot win.
A father protects his children.
Where are you going?
To find Jack.
You know everyone else is in the library.
Matthew is out hunting Jack.
Hunting?
But Jack is family.
When a vampire shows signs of blood rage,
they're killed. By order of the Congregation.
And because I'm a carrier,
Matthew was charged with killing every vampire I sired in New Orleans.
And every vampire they sired.
Hardly any of my family survived.
Matthew spared the carriers, but the cull was the only way
to stop them exposing vampires to humans.
Where are you, Jack?
I know you're there.
You've come to kill me.
I understand.
I stole these.
I had to kill a man to get them, but it was all that I could find of you.
I didn't know becoming a vampire would make me sick.
I was already dying, I thought
that what difference would it make?
When I realized I couldn't control myself,
I didn't want to live anymore, but Philippe told me to wait for you.
Philippe? My father?
He said that you would be the one to teach me to ignore what my blood
is telling me to do.
He can't have known how evil I would become.
The boy I knew in Blackfriars had no evil in him whatsoever.
I'm not the boy that you knew.
I won't fight you.
I've done so many things in my life I regret.
So many things that weren't even considered wrong hundreds of years ago.
Things change.
Philippe was right about that.
Matthew says that you taught him to control his blood rage.
Matthew realized his nature didn't have to be his destiny.
All I taught him was to pause and reflect.
See, learning control isn't easy, or quick.
Thank you.
You've also got Diana.
She'd do anything for you.
Don't let Matthew know.
About what?
Your feelings for Diana.
You can't hide them from me.
Philippe charged me to look after her.
I've spent her whole life keeping her safe.
And Diana is with Matthew now.
One day, perhaps soon, Gallowglass,
you will have to walk away from her.
I know.
But not today.
Domenico,
Thank you for coming.
It's the de Clermont pedigree their family tree from the Congregation archives.
Can you see anything wrong with it?
-No. -There's something missing.
They've hidden what they don't want us to know.
Can I trust you, Domenico?
I did as you asked.
Told the Congregation about the blood raged vampire.
You used it to attack the de Clermonts. I've had...
Even the de Clermont's secrets come out, eventually.
Benjamin.
I thought you were dead.
The de Clermont's day is nearly over.
It's about time Matthew de Clermont learns who he's dealing with.
Thank you.
For bringing him home.
You're welcome.
So, I'll be going to New Orleans.
I know.
Forming a scion will be hard.
But I think it's the only way to change things.
Take responsibility for everyone who's inherited my blood rage.
I'll take Marcus and Jack with me.
-Jack? -Yes.
I'm not leaving a blood raged vampire with my mate and our babies.
I don't want to be without you.
Nor do I.
Before I go, there's something I need to do.
With your help.
Anyone want to tell me what that is?
-It looks like human chromosome two. -It is human chromosome two.
But this is what we are gonna be focusing on:
Chromosome 24, known as CC.
What does CC stand for?
Before I answer that, I'd like to remind you
that you've all signed a nondisclosure agreement.
This is a highly sensitive, highly confidential research project.
'Cause lives are at stake here.
Lives have already been lost.
CC stands for...
Creature Chromosome.
This is my DNA.
And it's Creature Chromosome because...
I'm a vampire.
And before you ask, I can go outside during the day.
I'm Catholic and I have a crucifix. And when I sleep,
which is not very often,
I prefer a bed to a coffin.
These myths are all you really know of us.
We have had to hide from humans.
We've been vilified, we've been hunted,
because people fear what they don't understand.
I hope that by trusting you,
you can start to accept us.
Thank you.
Oh, and...
Miriam, whom you already know and trust, I hope,
is also a vampire.
And my wife, Diana, is a witch.
Although witches are, trust me, a whole other story.
So there we are.
Any questions?
How many?
-What? -Children, in New Orleans.
How many are left? To convince, for your scion?
Five.
Out of 20.
And then there's their children.
Your grandchildren?
None of them will be happy to see me with Matthew.
But they're still your family.
This is something I have to do.
I will be fine, I promise. Yeah?
Yeah, I know.
I need your support, Marcus.
And I know this won't be easy for you.
Find a cure for blood rage.
Fight to repeal the Covenant.
Defy the Congregation which upholds injustice.
And form a scion so we can live freely without Baldwin breathing down our necks.
And then?
I'll forgive you.
For the murders, for the secrets.
And I will be the first to offer my allegiance.
Yes?
Hello, Matthew.
Remember me?
Benjamin.
It's been a long time.
What do you want?
Check your email.
Trust me, Jack.
One day we'll look back on this together.
Is it on?
-Are you ready? -I don't want to.
I want to show Matthew what you can do.
That you're worthy of his respect, his love.
Give me.
They look scared.
Come on, Jack.
You wonder why Matthew left you.
Perhaps he knew you didn't have the spirit in you.
Not enough to be his son.
That's it, Jack.
That's it.
You see Matthew,
he truly is a child of your blood.
What is it that you want?
The whole family together.
You, me, Jack,
Diana.
We're all just wondering when the bodies will start turning up.
You brought the devil back to town, Marcus, what did you expect?
-Jack! -I'm here as Ransome's sire.
He can't change what's already happened.
But he can own it, Marcus.
Every time things were tough for her, she read her way out of it.
I don't understand how you know that.
If you have the page, you'd be wise to hand it over.
I know how you value your invisibility.
