The U.S.S. Enterprise has sent a landing party to an unknown planet to determine whether it was habitable. After a long day of exploration and data collection, everyone was tired. Even Spock felt a certain fatigue, weighing heavily on his limbs as he consulted with his science teams. After sending them off, he leaned back in his chair and rubbed his throbbing temple. The captain came a little late to their meeting. “There's a problem with the transporter. We'll probably have to stay here for the night,” Captain Kirk informed him. “Let's set up the tents.” Spock nodded and stood up, dismissing the dizziness as merely getting up too quickly. He helped coordinate the setting up of the tents while small chills racked through his body. The air seemed a little chilly, but no one else showed any discomfort. He overheard two researchers say it was a pleasantly warm night. It absolutely wasn't. At least not for him. When everything was ready, Spock excused himself and left early for his tent, which he was sharing with... someone; he couldn't remember. He pulled on a comfortable loose jumper and long sleeping trousers before preparing his sleeping place. He slid a heating plate under his thin mattress and grabbed a thick blanket. The tiredness was unbearable by now, tugging at his eyelids. There were still a thousand things to do, but they all became meaningless as he snuggled into his make-shift bed. Despite all the artificial warmth, he was still cold, the chills shaking through him. A slight congestion was building in his nasal passages and airways. Determined that he could overcome his discomfort by sheer force of will, Spock closed his eyes and tried to find peace in sleeping. Lying on his stomach, head on his arms and covered by the huge blanket, he looked a little too relaxed for a half-Vulcan and a little too peaceful for a human. Spock had already drifted into half-sleep when he heard footsteps. Someone was entering the tent.
