Something about the Terran idiom of pots and kettles should spring to mind here. Even so, Spock will always balance the benefit of all against the benefit of one. If it is between himself and Jim, then it is Jim that he should endeavor to let the universe keep. And if they might come upon an equilibrium, if it is possible that neither should be left behind? Well, that should be an ideal scenario indeed. All that aside: Jim might yet rattle the self-sacrificial tendencies from this Spock. Just as Spock may yet confirm for this Jim that his importance is paramount.

And thus, they reach such an impasse: that is one statement that would never sway this or that or another Spock. If he himself was so important, he should think, then why is Jim not? And he supposes this is why Jim spins about in his usual and chaotic thoughts. That he strikes upon an interesting compromise and course is no surprise to Spock. This is what makes him the Captain, after all.

Spock has no doubt he needn't remind Jim that his condition (as well as Jim's) is not stellar at the moment. Even so, he takes to Jim's suggestion without further thought. The sooner they might scale this obstacle, perhaps, the sooner they might clear this room. And, if there is a particular sort of mercy that the tower might show them, come upon a change of clothing.

"An inelegant solution, but a practical one."

Spock assesses the modeled position for no longer than he has to, eyes flicking up and away to focus upon the grain of the rock. He clears his throat, heart thudding away against his side. He reminds himself of what Jim has told upon the raft in the lower half of the room (he'd tell him, he'd left him know).

"As you wish," he says, the syllables rounded with the usual amount of capitulation. It is no hardship to answer that whim, but time is running out. "I believe the saying goes: 'on your mark.'"

He makes himself as pliant as he ought, settles with his back against Jim's.

Get set and go?
