recent material on you.
How are you feeling?
Okay.
Any problems?
Well, I had a fight with my girl.
Any confusion?
Are you experiencing any difficulty
identifying persons or objects?
Any language disorientation?
No.
Can you come back over to room 203?
What did you find to be a problem?
We'll take that up when you get here.
Connie.
Donna.
All right, Fred. Very good.
And this next test,
with your eyes covered...
...reach out and feel an object
with each hand.
You are to tell us if the object
presented to your left hand...
...is identical to the object
presented to your right.
One more thing, Fred.
We need an updated blood test.
So go down the hall to the pathology lab,
and they'll fix you up.
And by the time you get back, we should
almost be through with our evaluation.
I'll be upstairs with Hank.
You certainly seem
much more depressed today...
...than you did when we first saw you.
Pardon?
Last week, when we first saw you,
you were kidding and laughing.
Did you ever get her the flowers?
Crazy job they gave me.
But if I wasn't doing it,
someone else would be.
And they might get it wrong.
They might set Arctor up,
plant drugs on him and collect a reward.
Better it be me,
despite the disadvantages.
Just protecting everyone from Barris
is justification in itself.
What the hell am I talking about?
I must be nuts.
I know Bob Arctor. He's a good person.
He's up to nothing.
At least, nothing too bad.
In fact, he works for the Orange County
Sheriff's Office covertly...
...which is probably why Barris is after him.
But that wouldn't explain...
...why the Orange County Sheriff's Office
is after him.
Something big is definitely
going down in this house.
This rundown, rubble-filled house...
...with its weed-patch yard...
...and cat box that never gets emptied.
What a waste of a truly good house.
So much could be done with it.
A family and children could live here.
It was designed for that.
Such a waste.
They ought to confiscate it
and put it to better use.
I'm supposed to act like they aren't here.
Assuming there's a "they" at all.
It may just be my imagination.
Whatever it is that's watching...
...it's not human...
...unlike little dark-eyed Donna.
It doesn't ever blink.
What does a scanner see?
Into the head?
Down into the heart?
Does it see into me, into us?
Clearly or darkly?
I hope it sees clearly,
because I can't any longer see into myself.
I see only murk.
I hope for everyone's sake
the scanners do better.
Because if the scanner sees only darkly,
the way I do...
...then I'm cursed and cursed again.
And we'll only wind up dead this way...
...knowing very little
and getting that little fragment wrong too.
You show what we regard...
...more as competition phenomenon
than impairment.
Yeah?
Competition between the left and the right
hemispheres of your brain.
It's like you have two signals
that interfere with each other...
...by carrying conflicting information.
It's as if you have two fuel gauges
on your car.
They're studying
the same amount of fuel...
...but one says your tank is full,
the other registers empty.
They can't both be right.
And you as the driver have only
an indirect relationship to the fuel tank...
...via the gauges.
So, what does all this mean?
Well, I'm sure you know already.
You've been experiencing it
without knowing why or what it is.
Two hemispheres of my brain...
...are competing?
- Yes.
- Yes.
But why?
Substance D.
It often causes that, functionally,
