should be in there.
I'm gonna check the computer.
I think her husband transformed very early.
- What kind of medication was she on?
- She was on BuSpar and clonazepam...
...and I recently prescribed Risperdal.
Oh, Jesus, how ridiculous.
Her husband's infected with an alien virus,
and I prescribe an antipsychotic.
Yeah, well, I thought that sample you brought me was a Halloween gag...
...so who's to know?
That's interesting.
She had encephalitis when she was a child.
- Yeah, it almost killed her.
- It onset as a varicella complication.
- Her sister gave her the chickenpox.
- It might not be normal encephalitis.
There's acute disseminated encephalomyelitis, which is ADEM.
It affects substantia alba, the brain's white matter,
as opposed to gray matter.
It could be the reason why the virus hasn't been able to attack her system.
Well, we need to find her.
- Are you all right?
- Three years ago...
...Oliver got the chickenpox.
He'd had his shots, but it was a new strain...
...and in the middle of it, he had horrible dreams.
His temperature skyrocketed, he was hallucinating.
I took him to the hospital.
They diagnosed him with...
ADEM.
- Do you think Ollie might be immune?
- It's a possibility.
He's been at Tucker's for two nights and he's still texting you.
That could be the reason why.
What if they find out that he's immune?
I'm gonna call Galeano, tell him what's going on.
Oh, Ben.
And then we'll go and find Oliver.
- Yeah?
- Hi, it's Ben.
- Did you reach Fort Detrick?
- Yeah, we're here.
You wouldn't believe this place, man.
So much Nobel gold here, you'd think you were at Fort Knox.
Nadler, Stamets, Bohm, Dworetzky.
They're flying people in constantly.
Helicopters and planes are swarming all around.
Somebody realized there's a war going on,
and the only way to win it is in a lab.
They know what they're doing.
They got a first-stage protocol.
- They've isolated it?
- They can test for it.
- Do you have it?
- I'lI know in about an hour.
Listen, Steven.
Remember the woman we saw by the roadblock?
She had ADEM as a child.
Substantia alba.
lnteresting.
What I'm thinking is that if she's immune, maybe we have causality.
I get it.  I see it.
The ADEM affects the neuron structure.
If that were true, we could create a conjugate vaccine.
If possible, we could reverse the process.
But we need verification.
We need blood work, biopsy, MRl, PET scan.
- Do we know she's alive?
- We got an alternative.
Carol's son, Oliver.
He had ADEM.
- Wait.  Wait, are you stilI downtown?
- Yeah, we're in Carol's office.
- Okay, you need to get out of there now.
- Why?
Okay.  Yeah.  Bye.
- Carol.
- That was Ollie.  He's in Baltimore.
Baltimore?
Tucker's taken him to his mother's house.
I don't know why.
Well, I think I know why.
That roadblock, that's the beginning.
They've set up quarantine.
Stay within the barricade.
They're sealing off this part of the city.
- No, I have to get to Baltimore.
- Yeah, I know.
I have to get to Oliver.
I promised you that we're gonna find Oliver.
You gotta trust me.
Stay down.
We'lI do what it takes to get through this.
- Hey!
- Hey!
Ben.
I have it.
Tucker held me down and I have it.
Oh, God.
I'm so afraid I'm gonna fall asleep.
I'm so afraid I'm gonna lose him, I'm gonna lose you.
I'm gonna lose everything that matters.
No, no, no, you won't.
You can easy go for a week without sleep,
and then we'll find a pharmacy.
We'lI do whatever it takes so you can stay awake.
I just want you to know there is nothing I wouldn't do for you.
Nothing.
Carol, get out!  Get out.
We've gotta get out of the car now.  Get out!
- Ben!
- I'll find you!
- No!
- Find Oliver!
I love you!
I need to see your ID, ma'am.
Never mind.
Good evening, ma'am.
Train number 171 receiving on Track 5.

Mom.  Mom.
Come with me.
This will help you sleep.
We have a place for you to lie down.
(I'm on the train.
