SPOCK: As I recall the pattern of our fuel flow, there is an access tube leading to the matter-antimatter reaction chamber.
SCOTT: There's a service crawlway, but it's not meant to be used while the integrator operates.
SPOCK: Still, it is there, and it might be possible to shut off the fuel at that point.
SCOTT: What with?! Bare hands?!
SPOCK: A magnetic probe.
SCOTT: Any matter that comes in contact with antimatter triggers the explosion! And I'm not even sure a man can live in the crawlway in the energy stream of the magnetic field that bottles up the antimatter!
SPOCK: I shall try.
SCOTT: You'll be killed, man!
SPOCK: Unless a solution is found quickly, that fate awaits all of us.
SCOTT: Aye. You're right. What have we got to lose? But I'll do it, Mister Spock. I know every millimetre of that system. I'll do whatever has to be done.
SPOCK: Very well, Mister Scott. You spoke of the feel of the ship being wrong.
SCOTT: Aye. It was an emotional statement. I don't expect you to understand it.
SPOCK: I note it, Mister Scott, without necessarily understanding it. I propose to run an analysis through the ship's computers, comparing the present condition of the Enterprise with her ideal condition.
SCOTT: Mister Spock, we don't have time for that!
SPOCK: We have twelve minutes and twenty seven seconds. I suggest you do whatever you can in the service crawlway, while I make the computer study.
