It had been two days and they were no closer to a solution. McCoy sat dejectedly in the mess hall, chewing on a sprig of celery. He had been unable to eat meat, mostly because Spock had told him not to. Spock did have a good reason to say so. Vulcans could digest meat, but Spock had gone so long without he would probably just end up getting sick.

McCoy was depressed. He stared at his stupid hands. Spock's hands. The stupid switch was going to get them both killed. He sighed, leaning forward to place a chin onto the palm of his hand. He really needed something to cheer him up.

Suddenly, McCoy brightened. He quickly stood up and walked to the replicator, ordering McCoy supplement 54.

He carried the covered tray back to his table as Spock walked in. McCoy waved him over and Spock nodded resolutely. He grabbed a tray from the replicator and slumped over to sit next to McCoy.

"I now realize, Doctor, why you always believed it impossible for me to survive without copious amounts of sleep." He pulled the lid off his dish, taking a bite from a lavish salad.

McCoy nodded. "And, I suppose I realize why you always found that reaction odd. I haven't been able to sleep these past days." He shifted the cover off his own dish and prepared to take a bite of his meal.

Spock suddenly eyed him sharply, his newly acquired blue eyes squinting. "What is that?"

McCoy looked at Spock in surprise, his reaction had been… emotional? "It's just chocolate Spock."

"You can't eat that." Spock said, snatching the lid and placing it on the dish again.

"Why not!" McCoy exclaimed, pushing Spock's hand away from the dish.

"Doctor, right now, for all intents and purposes you are a Vulcan. A Vulcan can not eat chocolate, they will become inebriated."

McCoy's eyes widened. "Really?" he said maliciously. "I did not know that, Spock." He grinned wickedly, causing Spock to raise his eyebrows once more.

"Doctor, I realize you are not a Vulcan and can not control your emotions to such a degree but could you please stop smiling like that?" Spock said, hissing the last. He quickly rose, abandoning his plate and stalking off through the doors of the mess hall.

McCoy watched with open amazement at the sight. He felt almost obligated to go after Spock and say something sarcastic, but he quelled the feeling and put on a somber face.

If Spock wanted an emotionless McCoy, that's what he was going to get.
