Morg.
You are stranger.
I saw you on my ship!
Jim ...
she may not remember ...
or even really know.
Disassociation
could be complete.
It doesn't seem possible
she could have performed surgery
on Spock.
No, it doesn't.
You hurt Luma.
It is not permitted again
to hurt anyone.
Sorry.
We don't want
to hurt anyone.
If you wish to return
to your home, you may go.
No.
We'll stay here
and learn about you
and tell you of us.
Yes, for instance,
above it's cold
and harsh.
And below, it's warm.
The air is fresh.
Aye. There's no sun,
but there's light.
I wish to talk
to those in charge.
In charge?
Yes, the organizers,
the managers ...
the leader
of your people.
I am leader.
There is no other.
That's impossible.
Who built the machines?
Who are the doctors?
Who controls
this complex?
Control?
Controller?
Yes, the Controller.
The Controller.
Who ... Who controls?
I would like to meet --
to see him.
No. It is not permitted.
Never!
Controller is alone.
Apart.
We serve Controller.
No other
is permitted near.
We intend no harm.
You have come
to destroy us.
No, no, no.
We just want to talk to somebody
about Spock's brain.
Brain and brain!
What is brain?
It is Controller,
is it not?
Yes, yes,
in a way it is.
The human brain controls
the individual's functions.
Bones ...
Scotty ...
Spock's brain
controls ...
It's not possible.
Great ... leader.
Great leader!
We come from a far place
to learn from
your Controller.
You lie! You know me.
You have said that.
You came to take back
the Controller.
He is our friend.
You must take us to him.
We beg you.
Soon it will be
too late.
Do not take them,
Kara.
Do not take them
to the Controller!
They will be prevented.
You must take us --
I must learn what to do.
Come with me.
Keep them here.
Yes, mistress.
Ship 's Log.
Lieutenant Sulu recording.
I am holding the Enterprise
in orbit
about
planet Sigma Draconis 7.
Captain Kirk's hunch that
Spock's brain is on this planet
appears to be correct.
Ensign Chekov
remains on the surface
to act as liaison
between the captain
and the Enterprise.
I never felt anything
like that.
Every nerve in my body
was on fire.
I never believed the human organism
could take such pain.
These are on
to stay.
Must be a magnetic lock
of some kind.
No wonder the Morgs
are so obedient...
or terrified.
How is this place
kept functioning
by the primitive minds
we've met?
Those women could
never have set up
anything as
complex as this.
Why, that takes
engineering genius.
But there's no sign of engineering
genius in those women.
They were smart enough
to invent these training devices.
What a way to maintain
control over a man.
"Pain and delight,"
he said up above.
I'm sure you noticed
the delight aspect.
Yes, I certainly did notice
those delightful aspects.
But that, too,
was strictly under command
of the women.
How does Spock's brain
fit into this?
With a communicator,
we might be able
to find out.
This fellow is keeping us
from our property.
Isn't there a way
to correct that situation?
Science might
provide an answer.
It does, Captain.
Agreed, Doctor.
Science will triumph.
Come on, Scotty.
Bones, give them something
to keep them out for a while.
Spock.
Spock.
Come on, Spock.
Spock, you were on
this frequency, Spock.
Yes, Captain,
lam still here.
Have you returned
to the Enterprise?
No.
We might be able
to locate you,
if you gave us some idea of
what they were using you for.
Is it medical?
I am not certain.
I seem to have a body
which stretches into infinity.
Body?
Why, you have none.
Then what am l?
You are
a disembodied brain.
Fascinating.
It could explain much,
Doctor.
My medulla oblongata
is hard at work
apparently breathing,
apparently
pumping blood,
apparently maintaining
a normal physiologic temperature.
Spock, we don't
have time for that.
Why are you endangering
your lives by coming here?
