When Jim says sit, Spock sits, dropping a sturdy Vulcan frame into the chair with a scrape and staring across the table at the other man as he speaks, stiff-shouldered. Yes, this kind of conversation makes Spock uncomfortable. He would rather be beaten with a large stick.

"You make me uncomfortable because I don't understand my preference for you outside of my responsibilities." Aboard ship, things had been different. After working, if Spock hadn't picked up an extra back-half or front-half of an under-staffed shift, he spent his time with the group in the rec room. When he ate, he took his meals with the group. When he desired intimacy, Nyota found him. That he found himself still searching for that was strange, and that he found himself seeking out James T. Kirk when he was searching was uncomfortable. Because it didn't make sense.

"But I don't normally suffer from post-decisional regret, no. Therefore I must assume that it is a result of some unique combination of factors. I agree with what you're suggesting, but have no solution to offer you. I offer my apologies." It's beginning to sound very much like the conversation on the beach. Circular. Spock has no desire to be involved in circular anything.

The obvious answer is to turn it into a spiral. "Just because I don't understand doesn't mean that it isn't true."
