The lift doors slid open just in time for McCoy to see a dark finger slide off Spock's shoulder and hear the end of a flirtatious "See you later." He barely contained a smug snort as the first officer joined him inside and turned to face the closing doors. Spock stared straight ahead, not acknowledging him. McCoy wished he had gotten his zinger in when he had a chance.

...but alas, he hadn't.

...but damn, if this wasn't a big ship, and every second with that pointy-eared bastard was like an hour with a judgmental mother-in-law.

"Say, Spock..." McCoy finally broke the silence.

"Yes doctor?" Spock answered, glancing at him.

"Well—purely as a matter of biological curiosity, do you and Uhura ever-"

"Like many dissimilar animal hybrids, I am infertile but physically competent." There was a pause. Spock turned to him. "...If that was in fact your inquiry."

McCoy put a hand on his hip, scratched his chin, and bit the inside of his cheek. The lift doors slid open. "...Y'know, that wasn't my inquiry, but thanks for the information!" he replied as he left, in a tone that implied he was not at all thankful for the information.
