Dress uniforms, spit and polish.
I don't know how much longer
I'll be able to stand this.
I feel like my neck's in a sling.
The Vulcans are the last delegates we have to pick up.
As soon as they're aboard, we'll be able to relax.
Sure. A formal reception tonight,
114 delegates aboard for two weeks,
32 of them ambassadors,
half of them mad at the other half,
and everyone touchier than a raw antimatter pile
over this Coridan question.
[Chekov] Shuttlecraft approaching
with Ambassador Sarek's party -- one minute.
Bring them aboard, Mr. Chekov.
[Chekov] Standby to recover shuttlecraft.
Honor guard to the hangar deck.
[Technician] Clear hangar deck. Clear hangar deck.
Hangar deck pressurizing.
How does that Vulcan salute go ?
That hurts worse than the uniform.
Captain James Kirk.
My First Officer Commander Spock.
Vulcan honors us with your presence. We come to serve.
Your service honors us, Captain.
Chief Medical Officer Dr. McCoy.
and she who is my wife.
Our pleasure, madam.
I'll arrange a tour of the ship.
Mr. Spock will conduct you.
I prefer another guide, Captain.
As you wish, Ambassador.
Mr. Spock, we'll leave orbit in two hours.
Would you care to beam down and visit your parents ?
Ambassador Sarek and his wife
are my parents.
Space -- the final frontier.
These are the voyages of the Starship Enterprise.
Its five-year mission --
to explore strange new worlds,
to seek out new life and new civilizations,
to boldly go where no man has gone before.
Captain 's log, Stardate 3842.3.
We have departed Vulcan
for the neutral planetoid code-named Babel.
Since it is in our sector,
the Enterprise has been assigned
to transport ambassadors of Federation planets
to this vitally important council.
The issues of the council are politically complex,
the passengers ...
This is the engineering section.
There are a number of emergency backup systems
for the main controls.
Over here are a number of control computers.
After all these years among humans,
you still haven't learned to smile.
Humans smile with so little provocation.
And you haven't come to see us in four years, either.
The situation between my father and myself
has not changed.
My wife, attend.
A moment, if you please.
Yes, Captain ?
Explain the computer components.
I gave Spock his first instruction in computers, Captain.
He chose to devote his knowledge to Starfleet
instead of the Vulcan Science Academy.
If you will excuse me, Captain.
I'm sorry, Ambassador.
I did not mean to of fend.
I thought that --
Offense is a human emotion.
I'm returning to my quarters.
Continue, my wife.
Mrs. Sarek, I just don't understand.
I'm afraid you couldn't pronounce the Vulcan name.
Can you ?
After a fashion, and after many years of practice.
Shall we continue the tour ?
My husband did request it.
It sounded more like a command.
Of course. He's a vulcan. I'm his wife.
And Spock is his son.
You don't understand the Vulcan way, Captain.
It's a better way than ours.
But it's not easy.
It has kept Spock and Sarek
from speaking as father and son for 18 years.
Spock is my best officer ...
and my friend.
I'm glad he has such a friend.
It hasn't been easy on Spock.
Neither human nor Vulcan.
At home nowhere ...
I take it that Spock disagreed with his father
on a choice of career.
My husband has nothing against Starfleet.
But Vulcans believe that peace should not depend on force.
Starfleet force is used only as a last resort.
We're an instrument of civilization.
And it's a better opportunity
for a scientist to study the universe
than at the Vulcan Science Academy.
But Sarek wanted Spock to follow his teachings ...
as Sarek followed his own father's teachings.
They are both ... stubborn.
A human trait, Captain ?
[Uhura] Bridge to Captain Kirk.
Captain, I've picked up some sort of signal.
Just a few symbols.
That's what bothers me, sir.
Impossible to locate.
There wasn't enough of it.
Sensors show nothing in the area,
but it was a strong signal, as though it was very close.
Go to alert status 4.
Begin long-range scanning. Kirk out.
Captain 's log, Stardate 3842.4.
The interplanetary conference
will consider the petition of the Coridan planets ...
to be admitted to the Federation.
the Coridan system has been claimed by some of the races ...
now aboard our ship as delegates --
races who have strong personal reasons ...
for keeping Coridan out of the Federation.
The most pressing problem aboard the Enterprise ...
is to makesure open warfare ...
doesnot break out among the delegates ...
before the conference begins.
Mr. Ambassador, I understand you had retired
before this conference was called.
Forgive my curiosity,
but as a doctor, I'm interested in Vulcan physiology.
Isn't it unusual for a Vulcan to retire at your age ?
You're only 102.
102.437 precisely, Doctor,
measured in your years.
I had other concerns.
Sarek of Vulcan.
Do you vote to admit Coridan to the Federation ?
The vote will not be taken here, Ambassador Gav.
My government's instructions will be heard
in the council chambers on Babel.
You ! How do you vote,
Sarek of Vulcan ?
Why must you know, Tellarite ?
In council, his vote carries others.
I will know where he stands ...
Tellarites do not argue for reasons.
They simply argue.
No. You --
Gentlemen. Ambassador Sarek is quite correct.
This is not the council chamber of Babel.
I'm fully aware that the admission of Coridan
is a highly debatable issue,
but you won't solve it here.
You are correct, Captain.
My apologies, Captain.
You will excuse me.
Have you met Gav before, Ambassador ?
We debated during my last council session.
Ambassador Gav lost.
Spock, I've always suspected
that you were a little more human
than you let on.
Mrs. Sarek, I know about the rigorous training
of the Vulcan youth,
but tell me, did he ever run and play
like the human children,
even in secret ?
Well, he, uh ...
he did have a pet sehlat he was very fond of.
It's sort of a -- a fat teddy bear.
A teddy bear ?
Excuse me, Doctor.
It has been a rather long day for my wife.
A teddy bear.
Not precisely, Doctor.
On Vulcan, the teddy bears are alive,
and they have six-inch fangs.
[Chekov] Bridge to Captain Kirk.
Captain, sensors are registering
an unidentified vessel pacing us.
On my way.
All duty personnel on yellow alert.
Don't alarm the passengers. Kirk out.
A small ship, Captain.
It's been there five minutes, outside phaser range,
at extreme limit of sensors.
Identification, Spock ?
Sensors indicate the size of a scout ship,
but the configuration is unfamiliar.
Does she answer a hail ?
I've tried all frequencies
and a universal translator. No response, sir.
Maintain translator broadcast.
Check records for authorized ships.
Starfleet records no authorized vessel in this quadrant
Care to guess what she is ?
Guess, Captain ?
I shall need more data for my estimate.
Mr. Chekov, plot course to intercept that vessel.
I want to see what she looks like close up.
You embarrassed Spock this evening.
Not even a mother may do that.
He is a Vulcan.
He's also human.
He's a Starfleet officer.
I thought you didn't approve of Starfleet.
It is not a question of approval.
The fact exists -- he is in Starfleet.
He must command respect if he is to function.
Sarek, you're proud of him, aren't you ?
You're showing almost human pride in your son.
It does not require pride
to ask that Spock be given the respect which is his due,
not as my son, but as Spock.
Do you understand ?
Not really, but it doesn't matter.
I love you anyway.
I know. It isn't logical.
Vessel changing course,
heading toward us at high warp speed.
Ready main phasers.
Phasers armed and ready, sir.
They were traveling at approximately warp 10.
Back on original course, Mr. Chekov.
Report on intruder's movements.
Captain, Starfleet acknowledges report on our situation
and confirms-- no authorized Federation vessel
in this quadrant.
Back on original heading, Captain.
The intruder changed course immediately after we did.
It's ... paralleling us again.
Well, we have a shadow.
Faster, more maneuverable ...
Mr. Spock, full analysis of sensor readings.
I want to know who that intruder is.
Vulcan, I would speak to you.
It does seem unavoidable.
How do you vote on the Coridan admission ?
You seem unwilling to wait
for the council meeting, Ambassador.
We favor admission.
You favor ? Why ?
Under Federation law, Coridan can be protected
and its wealth administered for the benefit of its people.
That's well for you. Vulcan has no mining interest.
Coridan has nearly unlimited wealth of dilithium crystals,
but it is underpopulated
This invites illegal mining operations.
Illegal ? You accuse us ?
Some of your ships were carrying coridan dilithium crystals.
You call us thieves ?
Whatever arguments you have between yourselves is your business.
My business is running the ship.
As long as I command, there will be order.
Of course, Captain.
There will be payment for your slander, Sarek.
Threats are illogical.
And payment is usually expensive.
Security to Captain Kirk.
I'm on deck 11, section A-3.
I've just found one of the Tellarites murdered.
I think it's the ambassador himself, sir.
How was he killed ?
His neck was broken.
By an expert.
From the nature and location of the break,
the killer knew exactly where to apply pressure
to snap the neck instantly.
Who aboard would have that knowledge ?
the method is called tal-shaya.
It was considered a merciful form of execution
in ancient times.
A short time ago,
I broke up an argument between Gav and your father.
Spock, do you realize
that makes your father the most likely suspect ?
Vulcans do not approve of violence.
You're saying he couldn't have done it ?
I'm merely saying
it would be illogical to kill without reason.
But if he had a reason ...
could he have done it ?
If there were a reason,
my father is quite capable of killing ...
logically and efficiently.
Mrs. Sarek, I'm sorry to disturb you.
I must speak to your husband.
He's been gone for some time.
It's his habit to meditate in private before retiring.
What's wrong ? Spock ?
You want something of me, Captain ?
Ambassador, the Tellarite Gav has been murdered.
His neck was broken, Mr. Ambassador,
by what Spock describes as tal-shaya.
where were you during the past hour ?
Captain, you're not accusing him ?
If only on circumstantial evidence,
he is a logical suspect.
I quite agree.
Then where were you during the hour ?
In private meditation, Captain.
Spock will tell you
that such meditation is a personal experience,
not to be discussed.
especially not with Earthmen.
That's a very convenient excuse.
What's wrong ?
It's difficult to say with Vulcan physiology,
but I believe it's something to do with his cardiovascular system.
Can you help him ?
I don't know that yet either.
Yes, Captain. I get sensor readings of tri-tritanium
from the alien ship's hull.
I'm sorry about your father.
Yes, it could adversely affect our mission.
Aren't you worried about him ?
Worry is a human emotion, Captain.
I accept what has happened.
The ship's hull seems to have a high density level
or is cloaked against sensor probes.
It is manned, but sensors cannot make out specifics.
Well, the Romulans have nothing like it.
Certainly not the Federation or the neutral planets.
What about the Klingons ?
I think it unlikely it is one oftheirs.
Who, then ?
I picked up the last part ofa transmission
Just like that other one.
I put the recorder and the directional locator on it.
Mr. Chekov, directional locator indicates source
bearing 27, mark 8.
It's the intruder ship, sir.
Switch recorder to Mr. Spock's station for decode.
The directional locator indicates ...
reception point somewhere within the body of this ship.
A personal receiver ?
Somebody on board is in contact with that vessel ?
But I cannot decode this transmission.
Why not ?
It is in no known code.
There's no detectable pattern.
No standard references apply.
Are any conclusions possible from the information ?
It fits none of our computer records,
and it is alien.
Someone out there playing tag ?
Lieutenant, you've got your sensor locator on a wide beam.
Tighten your field to the interior of the ship.
If that alien vessel starts transmitting again,
I want to know
who on board the Enterprise is receiving.
Bones, how is he ?
From instrument readings,
our prime suspect has a malfunction in a heart valve.
It's similar to a heart attack in a human.
But with Vulcan physiology,
it's impossible to tell without an operation.
Mrs. Sarek, has he had any previous attacks ?
There were three others.
My physician prescribed Benjisidrine for the condition.
Why didn't you tell me ?
There was nothing you could have done.
when did you have these attacks ?
Two before we left Vulcan.
The third a few hours ago.
I was on the observation deck.
When the Tellarite was murdered,
I was quite incapacitated.
There were no witnesses ?
Doctor, do you propose surgery for the heart defect ?
I'm not sure. It's tough enough on a human.
On a Vulcan, an ordinary operation's out of the question.
Because of the construction of the Vulcan heart.
I suggest that a cryogenic open-heart procedure
would be the logical approach.
Bones, what about it ?
Well, I'm glad somebody's asking me something around here.
Well, the procedure they're discussing
would require tremendous amounts of blood for the patient.
I've checked the blood bank.
There isn't enough Vulcan blood and plasma
to even begin such an operation.
There are other Vulcans aboard.
My blood type is T-negative.
Somewhat rare, even for a Vulcan.
Yes, I'd say that's rare.
My blood is T-negative.
We've run a number of blood tests on Mr. Spock.
It isn't true Vulcan blood.
It has human blood elements in it.
It should be possible to filter out the human factors.
Even you couldn't give that much blood, Spock.
It would kill you.
Mrs. Sarek, you must understand
the chances are extremely small
to find a way to produce sufficient T-negative blood.
I would estimate the odds --
I see it, Spock,
but that was a Rigelian.
Rigelian physiology is very similar to Vulcan.
"Similar" is not good enough.
It's still experimental.
But it does look promising.
We would need such great amounts of blood
that, even if the drug worked on the Vulcans,
which I'm doubtful,
it would still drain Sarek to a critical level.
I consider the safety factor low,
Plus the fact
I've never operated on a Vulcan before.
Oh, I've studied the anatomical types.
I know where all the organs are.
But that's a lot different
from actual surgical experience.
So if I don't kill him with the operation,
the drug probably will.
What drug, Doctor ?
My husband is asleep.
What drug ?
A chemical stimulant
to speed up reproduction and replacement of blood in the body.
It's, uh, only experimental.
It has been used successfully
on test subjects on Rigel 5.
It places a tremendous strain
on the spleen and the liver.
In Sarek's condition,
the stimulant would kill him.
I underwent a physical examination last week.
Would you pull those records, please ?
You're perfectly healthy, Mr. Spock.
What has that got --
You're going to use it on yourself --
a transfusion from you to your father ?
It would seem the only answer.
It could damage you internally.
It could kill you.
I'm sorry, Spock.
I can't sanction it.
And I refuse to permit it.
I won't risk both of you.
Then you automatically condemn Sarek to death.
And you, Doctor,
have no logical alternative, either.
If you do not operate,
Sarek will die.
You now have the means to perform the operation.
I am volunteering myself as the blood donor.
I'll be at my station until you require me.
Agh ! Ohh !
I'm on deck five near my quarters.
I've been attacked by an Andorian.
[Mr. Spock] Captain 's log.
First Officer Spock in temporary command.
The captain 's been critically wounded
by one of the delegates to the Babel conference.
The ship is on alert status.
We are still being followed by the intruder vessel.
It's a bad wound --
punctured left lung.
A centimeter or so lower,
it'd have gone through the heart.
I'll be in the brig
questioning the Andorian prisoner.
the K-2 Factor is dropping.
your father is much worse.
There's no longer a choice.
I have to operate immediately.
We'll begin as soon as you're prepared.
My first responsibility is to the ship.
Our passengers' safety is by Starfleet order offirst importance.
We are being followed
by an alien, possibly hostile vessel.
I cannot relinquish command
under these circumstances.
You can turn command over to Scotty.
On what grounds, Doctor ?
do not recognize personal privilege.
I'll be in the brig interrogating the Andorian.
He is Thelev,
a minor member of my staff.
I know nothing of him
except that he has served adequately.
He's been subjected to questioning
under verifier scan and truth drug.
He reveals nothing.
I suggest his mind has been so conditioned
as part ofa preconceived plan.
My people are a violent race,
but we've no quarrel with Captain Kirk.
Apparently Thelev did.
You suggest a plot.
How could it profit us
to harm the captain ?
I do not know.
There is no logic
in Thelev's attack upon the captain.
There is no logic in Gav's murder.
Perhaps you should forget logic
and devote yourself to motivations
of passion or gain.
Those are reasons for murder.
Spock, you must turn command over
to somebody else.
When I was commissioned,
I took an oath to carry out responsibilities
which were clearly and exactly specified.
Any competent officer can command this ship.
Only you can give your father
the blood transfusions that he needs to live.
Any competent officer can command this ship
under normal circumstances.
The circumstances are not normal.
We're carrying over 100 valuable Federation passengers.
We're being pursued by an alien ship.
We're subject to possible attack.
There has been murder and attempted murder on board.
I cannot dismiss my duties.
Duty ? Your duty is to your father.
but this must take precedence.
If I could give the transfusion
without loss of time or efficiency,
Sarek understands my reason.
Well, I don't.
It's not human.
That's not a dirty word.
You're human, too.
Let that part of you come through.
Your father's dying.
Mother, how can you have lived on Vulcan,
married a Vulcan, raised a son on Vulcan,
what it means to be a Vulcan ?
If this is what it means, I don't want to know.
It means to adopt a philosophy
which is logical and beneficial.
We cannot disregard that philosophy
merely for personal gain
no matter how important that gain might be.
Nothing is as important as your father's life.
Can you imagine what my father would say
if I were to agree,
if I were to give up command of this vessel,
Jeopardize hundreds of lives,
risk interplanetary war --
all for the life of one person ?
When you were five years old
and came home stiff-lipped, anguished,
because the other boys tormented you
saying that you weren't really Vulcan ...
I watched you
knowing that --
that inside ...
that the human part of you was crying ...
and I cried, too.
There must be some part of me in you,
some part that I still can reach.
If being Vulcan is more important to you,
then you'll stand there
speaking rules and regulations from Starfleet
and Vulcan philosophy
and -- and let your father die and ...
and I'll hate you
for the rest of my life.
Oh, go to him now.
[Nurse Chapel] Dr. McCoy.
I'd like to get my hands
on the guy with the sledgehammer.
The one who hit you ?
No. The one inside my head.
How long have I -- Ohh.
Let that be a lesson.
Just lie there
and be happy you're still alive.
How's Sarek ?
If I could only operate.
What's stopping you ?
I thought you were all ready.
When you became injured,
Spock assumed command.
he's staying there until you're back on your feet,
even if it costs Sarek his life.
I can't damn him for his loyalty,
for doing his duty,
but I'm not going
to let him commit patricide.
Jim, if you stand,
you could start to bleed again.
Sarek will die without that operation,
you can't operate
without transfusions from Spock.
I'll convince Spock I'm all right
and order him to report here.
Soon as he leaves the bridge,
I'll turn command over to Scotty
and report to my quarters.
Will that fill your prescription ?
I'll take over, Mr. Spock.
You report to sickbay.
Are you all right ?
I've certified him physically fit.
Since I have an operation to perform
and both of us are required ...
Get out, Spock.
Chekov, what's the status of the intruder ?
Uh, no change, sir.
Maintaining its distance.
Any further transmissions, Lieutenant ?
Call Mr. Scott to the bridge.
the alien vessel is moving closer.
Relay that order.
Captain, I'm picking up the alien signal again,
but it's coming
from inside the Enterprise.
Specific origin ?
From the brig, sir.
Security, to the brig.
Search the prisoner immediately.
Mr. Spock's blood-reproduction rate
is up over 200%.
Sarek's heartbeat has risen to 324.
Blood pressure -- 90 over 40, dropping.
I wish I knew
whether that was good or bad.
Initiate sterile field.
Where do you think you're going ?
I must see the captain.
My patients don't walk out on an operation.
The alien ship --
if their power utilization curve isn't the norm,
it should be possible ...
to identify them this way.
So is your father's life.
We had to stun the Andorian.
He had a transceiver hidden in his antenna.
Captain, the alien ship
has changed course and speed --
moving directly toward us at warp 8.
Bring the prisoner to the bridge.
Phasers stand by to fire on my order.
Phasers manned and ready, sir.
Chekov, take over Spock's scanner.
Target, Mr. Chekov.
He's coming around again.
Fire as he passes, Ensign.
A clean miss, sir.
Report on his weaponry, Mr. Chekov.
Sensors record standard phasers, sir.
Standard phasers. Good.
They may have more speed,
but they're not giants.
Captain, the intercoms are jammed.
The ambassadors are asking what's going on.
Tell them to take a good guess,
but clear that board.
He's coming around again.
One more like that,
and I'll lose both these men.
Fire control locked into computers, Captain.
On my order,
fire photon torpedoes 2, 4, and 6.
Widest possible scatter.
Full spread missed, sir.
They're moving too fast.
Doctor, his heart's stopped.
The systems are off.
Then get me that old portable cardio-stimulator.
And call engineering
and have sickbay systems put on priority.
Number four shield has buckled, sir.
Shields firming up.
Number four's still weak, sir.
If they hit us there again, it'll go altogether.
Your friends out there are good.
They'll have to destroy this ship to win.
That was intended from the beginning.
You're not Andorian.
Damage reports coming in -- every deck.
Damage-control procedures, all decks.
That ship out there has phasers.
At least our weapons are alike.
Number two shield is gone.
Engineering, this is the captain.
Cut power on port side except for phaser banks.
At my signal,
cut starboard power.
Who are you ?
Find your own answers, Captain.
You haven't long to live.
You're a spy,
surgically altered to pass as an Andorian,
planted in the ambassador's party
to use terror and murder to disrupt us
and prepare for this attack.
cut power on starboard side.
maintain until further orders.
What are you doing ?
We're starting to drift, sir.
Shall I hold her on course ?
No. Stand by your phasers.
Phasers standing by.
He's just hovering out there, sir.
Looking us over.
We're dead as far as he knows.
You're baiting him.
You're trying to lure him in.
Here he comes.
Speed dropping close to sublight.
Hold your fire, Mr. Chekov.
Phasers locked on target.
Range ... closing.
Got him !
Secure from general quarters.
Lieutenant, open the hailing frequency.
If they wish to surrender ...
They could not surrender, Captain.
They had orders to self-destruct.
Lieutenant, relay to Starfleet command.
Tell them we have a prisoner.
Only temporarily, Captain.
You see, I had orders to self-destruct, too.
Quite painless, actually,
but there's no known antidote.
I anticipate another 10 minutes of life.
Take him to sickbay.
I seem to have ...
So did they.
Are you quite through shaking this ship around ?
Spock, Sarek -- how are they ?
You sure make it difficult for a surgeon trying --
Captain, come in.
That pig-headed Vulcan stamina --
I couldn't have pulled them through without it.
Some doctors have all the luck.
You'll find the alien --
We damaged their ship.
They destroyed themselves to avoid capture.
Bones, Thelev's body will be brought to your lab.
I want an autopsy.
He's an Orion, Doctor.
Intelligence reports that Orion smugglers
have been raiding the Coridan system.
What would they gain by an attack on Starfleet ?
and interplanetary war.
Of course, with Orion carefully neutral.
They'd clean up
supplying dilithium to both sides
and continue to raid Coridan.
The thing that confused me
was the power utilization curve.
It made them seem more powerful than a starship.
That ship was constructed
for a suicide mission.
Since they never intended
to return to their home base,
they could use 100% power on their attacks.
The thing I don't understand
is why I didn't think of it earlier.
You might have had
something else on your mind.
It hardly seems likely.
No, but thank you, anyway.
And you, Sarek,
would you also say thankyou to your son ?
I don't understand.
For saving your life.
Spock acted in the only logical manner open to him.
One does not thank logic, Amanda.
I'm sick to death of logic.
You know how I feel about your logic ?
Emotional, isn't she ?
She's always been so.
Indeed ? Why did you marry her ?
At the time,
it seemed the logical thing to do.
Oh. Bones ...
If you keep arguing with your kindly family doctor,
you're going to spend your next 10 days right here.
If you cooperate, you'll be out in two.
Doctor, I'll return to my station now.
You are at your station.
Dr. McCoy, I believe you're enjoying all this.
Indeed. I've never seen him look so happy.
Well, what do you know ?
I finally got the last word.
