may be infected
in the U.S. Alone already.
How can we know
if we've got it inside us?
We can't. We just have to make sure
we stay awake.
The change occurs when the body
undergoes REM sleep.
We'll watch each other,
make sure we don't fall asleep.
Fort Detrick is 50 miles from here.
We get down there, they'll take us in.
I'm not going anywhere withoutmyson.
Carol and l'll go and find Oliver.
Then we'll meet you at Fort Detrick.
Look.
Where did you go? I was worried.
Oh, God.
You've always trusted me.
We've never been apart.
You have to come to me,
orwe can't be together.
I need you.
Henyo.
Are there other people in the house?
Form a line.
Take a seat on the buses.
Staywithin the barricade.
Thank you for your cooperation.
We should turn around.
We should not go there.
No. They'll notice.
Juststay calm, keep walking,
look them straight in the eye.
- Stop it! Let go!
- Staywhere you are!
I know what's going on!
We don't have to go with them!
Get on the ground, ma'am.
I've been asleep.
Don't you get it? I've alreadyslept.
That's one of my patients.
Would you let go of me?
Help!
Let's go.
Good luck.
She was saying she slept.
Did you hear her?
So if she slept and she were infected,
that would mean she was immune.
Possibly. There might be something
in hermedical records.
Do you keep them in your office?
Yeah.
215, are you still requesting backup
for a trafficstop at Hampshire and M?
Yes, dispatcher, we've got... 215, we need
backup as soon as you can. Over.
Copy, 215. ETAfive minutes.
All units, please be advised,
inoculations have begun.
Scout 42, see the National Guard commander
at 56th Street to assist in crowd control.
Copy. ETAfive minutes.
Here's what I have. G.P. Notes 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 thatsample
you broughtme 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.
- Hersister gave her the chickenpox.
- Itmight not be normal encephalitis.
There's acute disseminated
encephalomyelitis, which is ADEM.
It affects substantia alba, the brain's
white matter, as opposed to graymatter.
It could be the reason why the virus
hasn't been able to attack hersystem.
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 theyfind out that he's immune?
I'm gonna call Galeano,
tell him what's going on. Okay?
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 onlyway 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?
- L'll know in about an hour.
Listen, Steven.
Remember the woman we saw by
the roadblock? She had ADEM as a child.
Substantia alba. Interesting.
What I'm thinking is that if she's immune,
maybe we have causality.
I get it. I see it.
