A/N: Had two different ideas with this and decided to combine them for a more well-rounded experience. Enjoy!

"Doctair, haf you ever vondered vhat happens to the passengers vhen you lose a train of thought?"

McCoy raised both his eyebrows as he looked at his patient. "No, Mr. Chekov, I have not."

Chekov seemed mildly perplexed by this as he stared at the ceiling. "Are they dead or should I declair them missing?"

"Probably just missing," McCoy replied smoothly. "After all, the train is simply lost, so it has to be somewhere, right?"

The navigator nodded slowly. "You are wery smart, Doctair."

"Thank you."

McCoy finished logging the latest vitals on Chekov's recovery. The bones in his leg were healing nicely and it was just a matter of waiting for all his pain medications to wear off. In the meantime, he often babbled. McCoy tried not to make his patients a source of amusement, but sometimes he couldn't help it. And other times, they were just a pain in the rear.

Speaking of which…

McCoy retreated into his office and fished around for the Pillow. Securing it, he walked into a private room to address his other patient: Jim Kirk.

Jim was also awake and staring at the ceiling, moving his mouth slightly as if speaking to someone. His arms flopped off either side of the biobed. He lolled his head towards McCoy's direction when the doctor entered.

"Heyyy, Bones," he greeted tiredly. A giggle found its way out of his chest.

"Good to see awake, Captain," McCoy replied. He put the Pillow on Jim's chest. "Hold this."

Kirk's arms automatically latched around the pillow without complaint. "How d'you do that, anyhow?" he slurred.

"How do I do what, Jim?" McCoy asked, keeping his attention focused on the panel's readings. He made a few notes on his PADD.

"Make your eyes so blue?"

McCoy sighed heavily. This was why he hated giving Jim trimaplodelene, but nothing else worked as well for clearing an infection from the man's system.

"I'm not answering that, Jim."

Kirk whined and clutched the Pillow tighter. "But what's your secret?"

"It's no secret, and you'll figure it out in a coupla' hours." McCoy finished his notes and gave Kirk another once-over.

Jim met his eyes. "But I would like you to show me."

McCoy rolled his eyes. "I'll check back in a bit, okay?" He left before Kirk could try another ploy.

Interestingly, as he walked back to the main ward, McCoy could hear another voice accompanying Chekov's. His whole countenance brightened when he recognized whose it was.

"…as such, 'down' is made irrelevant."

"But can you prove it, Mistair Spock?"

McCoy stepped in just in time to catch the exasperated look that flitted across Spock's face. "Ensign, I have effectively just done so. Gravity is most apparent as localized events tied to sufficient mass, or mimicked through the properties of spin or artificial recreations. Because the Enterprise, in this case, serves as its own generator of artificial gravity, 'down' only matters in regards to the events within the ship, not the state of the ship itself." Spock finally seemed to notice McCoy, and his accompanying grin.

"Doctor. I came to inquire as to Ensign Chekov's and Captain Kirk's status," he said stiffly. "Though it appears the ensign is... still recovering."

"Doctair, how do ve know that the ship isn't flying upside-down?" Chekov queried anxiously.

"Because if it were, we'd all be walking on the ceiling," McCoy answered. The navigator seemed satisfied with that and nodded his head. Spock opened his mouth but McCoy beat him to it. "My office?"

The Vulcan followed without complaint.

"They're both going to make a full recovery," he reassured Spock once the door closed behind them. "I expect their current round of pain meds should wear off in another few hours before I discharge them to their quarters."

"Thank you, Doctor. Though, if I may ask, why is the Captain not in the main ward?"

McCoy exhaled heavily. "Because every time I have to give him the medication I did he gets a little… suggestive."

Spock raised an eyebrow. "Suggestive, Doctor?"

"Look, everyone reacts differently, and he's not the only one for this brand. But he's loosened up enough to make passes at whoever's closest and can get a little handsy without his Pillow. Don't worry, he's got his Pillow," McCoy added.

"I was not aware that there was cause for 'worry'," Spock said carefully. "Would it be permissible for me to see him?"

McCoy snickered, but then regained his veneer of professionalism. "I try to keep visitors to a minimum, Spock. It can be pretty embarrassing to find out later that you tried to hit on everything that moved while you were doped up. And trying to talk to him would be about as productive as it is with Chekov."

Spock straightened at that. McCoy wondered how much of their conversation he had missed. "Very well. Alert me when both are discharged from Sickbay… and coherent."

He chuckled. "Sure, Spock."
