When McCoy entered the enterprise, Nurse Chapel briefed him on the state of their captain and first officer.
"He was in pain. After he called for you, he just fell on the bed and began yelling. Some crewmen subdued him and gave him anesthetic to sleep. But..." Nurse Chapel bit her lip, "but it seemed it only sent one of them to sleep."
"Which one?" McCoy asked as the two rushed to sickbay.
"I don't know." Nurse Chapel shook her head, "this is all so confusing."
Bones turned to face her, "Could you tell which one was in pain?"
"Doctor, that's the thing... The way he yelled, the look in his eyes... Nobody could tell the difference. To us, it seemed like it was both Mr. Spock and Captain Kirk." She explained.
McCoy seemed a little worried as they approached the doors to sickbay. He nodded at the nurse and she began walking away.
When the doors opened, Spork was silently sitting crossed legged on top of the bed.
"Don't mean to interrupt." He remarked as he walked toward the meditating man.
"I had first thought that I needed to enter the machine again as to maybe reverse the process. I now realize the only thing I require is silence." The fusion replied.
"Oh?" McCoy slightly raised an eyebrow. "Why is that?"
Spork opened his eyes, revealing dark red bloodshot eyes (with tints of green) as if someone hadn't slept for days. "Because the pain I feel in my head disappears in silence."
"My god man, you took terrible." McCoy gasped.
He shook his head "How I look is irrelevant, Doctor."
"Okay then Spock, I'm going to assume you're Spock... What happened to Jim?" McCoy asked.
"He is asleep... As a Vulcan, I don't require as much as humans. I can go months without slumber." He said, closing his eyes again.
"You should go rest, Spock. It doesn't matter how much sleep your pointy-eared species can go without. You're in pain and sleep can help numb it." Bones replied.
"I do not need sleep. I need silence and..." Spock began to slowly stand from the bed, making sure to keep one hand on his forehead. "And to get to..." his face turned sources he clinched his mouth and shut his eyes.
McCoy ran to help but the Vulcan shrugged him off.
"I need to beam to Timon and Kals ship and enter the fusion machine again." Spock told the Doctor. He seemed to regain his strength and recover from an obvious headache.
"Spock... I think I understand why you'd want to try the machine again, but it could just make things worse." McCoy explained. "You need to lay down."
"I need to fix our situation, Bones. If not for myself and the Captain, then for Timon and Kal and whoever else was infected by the disease Kal is suffering from. There is a chance, however slim, that it could work. At this moment, it is the only chance the captain and I have. If you can offer any alternative, it is eagerly accepted. If not, our mind is made up." Spock walked away with an aura of determination following him.
McCoys frowned at the thought of Spock being right. Before returning to the side of Spock/Kirk, Dr. McCoy muttered
"Only Jim calls me "Bones"..."
They then proceeded on their mission to re-enter the fusion machine.
