Pike doesn't look up right away when the door swishes open, just gives Spock a simple "sit" direction while he keeps scanning the com screen in front of him. He's long mastered the art of intimidation, especially on lowly cadets, but e's a bit interested to see how effective any of these are on a Vulcan. Human failings, he knows intimately. Vulcans are a whole different matter, though.

Spock will have to sit there until Pike thinks he's squirmed enough.
