The Shat's theatricality in that moment doesn't really subscribe to the notion that he knew anything about an imminent rescue, at all. I mean, Kirk's wild-eyed, shaking with anger yell was more than just a vocal outburst ... am I right? Or am I right? Whose benefit was that for, then, if he knew Spock's plan - aside from ours, that is? His ex-wife's? His kid's? Bones, even? It's well-handled, dramatically ... I like how the camera slowly zooms in on him, as Khan spouts his words of hate ... but the scream is so absurd it's almost comical. When Darth Vader tells Luke who his father is, the scream Luke responds with falls right into that very same category. I laughed when I first saw that ... it was so rediculous and over the top. Same with The Shat's delivery.
