What's the old expression?

You've got a screw loose

That's pretty accurate

That's how I've always

visualized the human brain

An extremely

complex machine

and the more complex you make

a machine

the more inevitable it becomes

you will experience errors

glitches

loose screws

Like a record player skipping

you might find yourself

repeating the same actions

over and over again

You know you shouldn't

be doing it

Or you

keep doing it subconciously

when you know it's wrong

But you just can't

help yourself

You've lost control

of your machine

I... uh

ran out of bandages

so I just...

It's okay we got plenty

When did you first start iching?

Eleven months ago

Alright and where does it itch?

It's always in the same place

Where's Dr. Jensen?

He'll be in shortly

Have you undergone any prior‐

I've tried everything

Everything

Nothing works

It never stops

Are you new?

Where's Diana?

Now, on a scale from one to ten

how much pain?

Pain has nothing to do with this

It's not nerve damage or

psoriasis or trichotillomania

I've already been over this

a thousand goddamn times would

you please just get the Doctor!

Now I'mma need you to lower

your voice, okay?

We're working as fast as we can

we're not machines

Paging Dr. Jensen!

Prep her for immediate surgery

Val...

How are you?

Alright

So here's the breakdown of‐

The patient had incurred

brain damage

She lost consistent motor

control on the left side

of her body

You see, over the

eleven month period

she had actually penetrated

the parietal bone

She had itched a hole

through the side of her skull

and that night

she had scratched

the surface of her cortex

Who is running your machine?

Is it you?

Or have you lost control?

Did you ever have control

to begin with?

What if I described an ant?

A tiny red ant

Crawling on your forehead

slowly, making it's way

towards your hairline

and up to the crown of your head

You can feel it can't you?

Even though you know

it's not there

Can you resist the urge?

Or do you just...

...have...

...to scratch?
