Title: Ironically, no

Summary: McCoy and his son are hiding something, something neither wants anyone to know. Spock still manages to expose them. Things are going just fine until McCoy faints mysteriously.

Characters: Spock/McCoy, and son, and Kirk.

Author's notes: Finally! The trilogy will be completed! Be forewarned that this one has a plan, so it might actually be updated on a not-stupid schedule. But… If you review every chapter, I'm way more inclined to write. Hint.

By the way, it's a good idea to read the first two installments before you read this one. (A little piece of Irony, and An Ironic twist of fate, respectivly.)

Spock impassively activated Doctor McCoy's door again. He knew it was making an irritating beeping noise, and that McCoy had to hear it. He also knew that McCoy hadn't answered the first time, even though he had to be in there.

Activating the door a third time he finally heard a response.

"Don't come in! Give me a second."

Spock frowned at the Doctor's choice of words, unless something had happened to make the Doctor posses superhuman speed he would take more than a second, probably a lot longer in fact.

His suspicions were confirmed with, thirty-eight point two seconds later the door opened. McCoy himself stepped out, nervously keying the door to shut again and using his body to shield the Vulcan from seeing inside.

"So… What's up?"

Blinking stoically, Spock glanced at the door. "Clearly you are attempting to hide something from me. This would be abnormal behavior even if you weren't leaving your son unattended."

That got him a nervous twitch from the Doctor, "I don't know what you mean."

"I also suspect that this has something to do with him." Spock drew his eyebrows together slightly, "He is unharmed?"

McCoy nervously fingered his shirt collar. "He's fine." Seeing Spock's unbelieving look he nodded for extra conviction. "No really!"

"Allow me to enter."

"I… this is stupid."

"Obviously," Spock raised one straight edged eyebrow.

McCoy glanced nervously up and down the hallway.

"There is no one here but us, Doctor."

"Name's Leonard." He muttered, but he was clearly distracted. After a moment he seemed convinced that the hall was indeed empty. "Spock, can you keep a secret?"

"Based on your level of nervousness, at this point I cannot say with conviction that I would be able to keep your secret. There is clearly a threat."

"Would you stop being so logical, just for a second?"

Spock paused briefly. "I have not been logical for a second, now may I know what this 'secret' is?"

"This is a bad idea." McCoy said. He carefully keyed to door to open. As it complied and slid open, McCoy reached forward and snatched Spock by his shirt, turning and pushing him into the room. Diving in after him, he slammed the door shut.

Spock straightened his shirt with a downward tug. "Doctor, please-"

"Father?"

Spock paused, mentally running through variables. The only person in the Doctor's quarters who would call McCoy 'father' would be his son. Which was impossible, his son was only three days old.

Turning around he was met with some confirmation of his analysis, and some strange new variables to consider. A boy who appeared to be the human equivalent of twelve stood clutching a data pad in both hands like a life preserver. His eyes were an exact copy of McCoy's, in fact his entire body was an exact copy of an, obviously, much younger McCoy, save for pitch black and shiny hair.

At a loss for words, Spock turned from the boy to McCoy.

"Just a moment, Korbin, I need to explain things to Spock."

Korbin nodded, "I understand, I will wait. Don't take long. If he doesn't get it right away, he's not smart enough anyway." He turned around and began to consult his data pad again. Spock noticed it had something akin to Einstein's theory of relativity on it.

McCoy shook his head. "Ah, the joys of parenthood." Looking back to Spock he nodded sharply. "Right, Spock, I'd like you to meet Korbin, my son."

Author's notes: Chapter one! My God! Okay, I've had this planned for a while, finally (At 4 a.m.) Got to the writing part. Hope it turns out as well as it did in my head! By the way, blame the internet for the name Korbin. I needed a name and looked it up on the baby name website.
