That's not how the revised script went.And Spock only has a single line. So without Kelley there is no scene.
INT. BRIDGE
Spock and Kirk are in conference at the command chair. McCoy enters from behind them, looking somewhat bemused. He approaches them, stops. Kirk and Spock look at him.
KIRK
Yes, Bones?
McCOY
You might be interested. Lt. Palamas managed
a picturesque faint at breakfast this morning.
KIRK
Oh?
McCOY
Just after the smell of coffee made her slightly ill.
Kirk and Spock stare at him.
SPOCK
Should that be of significance to us, doctor?
McCOY
I don’t expect it to be to you.
(to Kirk)
But it should mean something to you.
KIRK
Something going around?
McCOY
I certainly hope not. I just finished examining her. She’s pregnant.
KIRK
What?
Even Spock looks surprised.
McCOY
You heard me.
KIRK
(beat)
Apollo?
McCOY
(nodding)
Apollo. Positively.
Kirk and Spock look stunned. McCoy continues, dryly.
McCOY
Now I’ll give you an interesting question to chew on.
What will the child be. Man? Or God?
(beat – to Spock)
You want to try that on your computer for size, Spock?
