is it?
Not exactly.
Why?
I used proto-matter
in the Genesis matrix.
An unstable substance which
every ethical scientist in the galaxy
has denounced
as dangerously unpredictable.
It was the only way
to solve certain problems.
So, like your father,
you changed the rules.
If I hadn't, it might have been
years, or never!
How many have paid the price
for your impatience?
How many have died?
How much damage have you done?
And what is yet to come?
Bridge, nothing happening here.
- This planet is ageing in surges.
- And Spock with it.
- It seems they're joined together.
- They are.
How long?
Days. Maybe hours.
I'm sorry.
It will be hardest on Spock.
Soon he will feel the burning
of his Vulcan blood.
- I don't understand.
- Pon Farr.
Vulcan males must endure it every
seventh year of their adult life.
Whoever they are,
they're getting closer.
- I'll go.
- No.
I'll do it. Give me your phaser.
Sir, Starfleet calling USS Grissom.
A warning about us.
- Response?
- Nothing. As before.
What's the Grissom up to?
Will she join us or fire on us?
Chekov, break silence. Send
Captain Esteban my compliments.
- How are we doing?
- How are we doing?
Funny you should put it
quite that way, Jim.
We are doing fine.
But I'd feel safer
giving him one of my kidneys
than what's scrambled in my brain.
No response from Grissom
on any channel.
Keep trying.
At regular intervals.
So it has come.
It is called Pon Farr.
Pon Farr.
Will you trust me?
We are secured from Warp Speed.
Now entering Genesis Sector.
Proceed at impulse power.
- Vessel entering sector.
- Yes.
Federation Battle Cruiser.
Have they scanned us?
Not yet.
Engage cloaking device.
I'd swear there was
something there, sir.
What did you see?
For an instant, a scout class vessel.
Could be Grissom.
Patch in the hailing frequency.
Grissom, this is Enterprise calling.
Please come in.
Grissom, this is
Enterprise calling. Do you read?
Spock!
I've come a long way
for the power of Genesis.
And what do I find?
A weakling human,
a Vulcan boy and a woman.
My Lord, we are survivors
of a doomed expedition.
This planet will destroy itself soon.
The Genesis experiment is a failure.
A failure?
The most powerful destructive force
ever created.
You will tell me the secret
of the Genesis torpedo.
I have no knowledge.
Then I hope pain
is something you enjoy.
- I ordered no interruptions.
- But, sir...
- Federation Starship approaching.
- Bring me up.
Grissom, this is Enterprise calling.
Do you read?
Grissom, this is Enterprise
calling. Please come in.
Battle Alert!
Grissom, this is Enterprise.
Admiral Kirk calling Captain
Esteban or Lieutenant Saavik.
- Report status.
- We are cloaked.
Enemy closing on impulse power.
Range five thousand kellicams.
Good! This is just the turn of luck
I have been waiting for.
- Nothing on my scanner, sir.
- Short-range scan, Mr Chekov.
Put it on visual, Mr Sulu.
Range three thousand kellicams.
Steady. Continue on impulse power.
Range two thousand kellicams.
Stand by to transfer energy
to weapons.
At my command.
There! That distortion, see it?
Yes, sir. It's getting larger
as we close in.
Firing range, sir.
Gunner...
Target engine only. Understood?
Understood clearly, sir.
- Opinion, Mr Sulu.
- I think it's an energy surge.
- Enough energy to hide a ship?
- A cloaking device.
Red Alert, Mr Scott.
One thousand kellicams and closing.
All power to the weapons systems.
Wait. Wait.
No shields?
If my guess is right, they'll have to
de-cloak before they can fire.
May all your guesses be right.
- Klingon Bird of Prey. Arming.
- Fire, Mr Scott!
Good shooting, Mr Scott.
Precautionary, Mr Chekov, shields up.
Emergency power to the thrusters!
- Sir, the shield's non-responsive.
- Scotty?
The automation system's overloaded.
I didn't expect combat, you know.
Fire!
Emergency power.
Prepare to return fire.
Mr Scott, can you transfer power
to phaser
