This is an answer to a prompt where Spock is more seriously injured than he realizes. This is part one and is still in progress.

"Bounty hunters. Why did it have to be bounty hunters?" Kirk looked over his shoulder, his chest heaving.

Spock stopped in deference to his human companions, as they did not have his Vulcan stamina and were not able to match his pace. "The emergency signal appeared to be quite genuine Captain. There was no reason to suspect-"

Kirk cut him off before he could finish. "We'll deal with that later. Now we have to get to the shuttlecraft before they figure out we escaped."

McCoy, chest heaving, glared at Spock in annoyance. "Just this once, I wish I could have your Vulcan stamina."

"It does have advantages under certain situations", Spock said as he surveyed their surroundings. "

"Yeah, yeah, I get it. You have a tough Vulcan hide. Speaking of which, you were awfully close to the explosion, are you all right?"

"I received merely cuts and bruises." Spock had set the bounty hunter's tricorder to explode and had been too close, but it had achieved the desired objective. The bounty hunters were stunned and Spock had used the opportunity to free Kirk and McCoy.

"Let me see." McCoy examined Spock's hands "They look all right, just some cuts. He lifted Spock's hand to examine his wrist when he paused and said, "What's this?"

Spock lifted his arm and his sleeve was wet, but not with blood. McCoy pulled up Spock's sleeve and it caught on a piece of metal embedded in his arm.

Spock looked at his arm impassively. "Interesting. I do not feel any discomfort."

"Do you mean that you don't feel the pain or that you don't feel anything."

Spock looked down at his arm as McCoy was probing the wound. "I do not feel anything. The area is curiously numb."

"I should probably remove this shard before we go. It could get dislodged or go deeper and cause more damage." He made Spock sit down on a nearby log and pulled out his medkit.

Spock pulled his hand away. "We don't have time for this doctor."

"Look, it will only take a minute and if I leave it in it could get deeper."

Kirk squatted next to the doctor. "You have a minute."

McCoy sprayed the area with disinfectant and used tweezers to pull the metal shard out. Spock cried out as jolts of electricity shot through his arm and spread through his body. He gasped and squeezed his eyes shut as he tried and failed to suppress the sensation.

"Spock what's wrong?"

Spock didn't answer, focusing on the sensations. He realized he had been holding his breath, then as the sensations gradually diminished, he breathed in slowly.

McCoy crouched next to Spock, tricorder out. "Spock what happened? You're pulse and blood pressure skyrocketed for a moment but it seems better now.

Spock opened his eyes. The sensation was now completely gone.

"You scared us for a minute. It almost looked like-"

Spock cut him off. "Whatever the sensation was, it is gone now.

"Well, let's get this cleaned up so we can go." McCoy picked up Spock's arm and rotated it. The act of rotation caused electricity to shoot through his arm again. It was not as intense as before, but it caused him to wince again.

McCoy pulled out his tricorder. "The shard must have been coated with a toxin for it to have this affect, but I'm not detecting anything." He put the metal shard into a specimen pouch. "I'll bring it with us just in case." He pulled out a bandage. "I'm going to wrap this lightly, all right?"

The barest touch caused brief shooting sensations, but he endured the discomfort.

"We should get him back to the Enterprise. There is no telling what type of toxin this is. "I've never seen anything quite like it."

"The shuttle is only about 2 kilometers away. If we can get there before the bounty hunters, we should be free and clear."

Spock rose from the log and a brief wave of dizziness caused him to sit down abruptly and he caught himself on his right hand and it collapsed under him as electricity once again pulsated throughout his body.
