Spock met Jim when he was 7 and Jim was 6. It has since been generally agreed that this was a mistake (or: the one where they grow up together and things are simultaneously better and worse for it).

Prompt: Starfleet!AU - Human!Erik thinks Charles is the worst Vulcan ever. In which Erik is distressed by a Vulcan shaking hands with him and then very blatantly inviting him to *cough* observe his nocturnal habits.

He knew the calm before a storm when he saw it. And one had been brewing for weeks now.

Traumatized by his experience on Tarsus IV, Jim Kirk runs away to Vulcan to undergo kolinahr.

He is somewhat reluctant to admit it, but he and Spock still aren’t actually friends. Jim doesn’t fight with him any more – they work together well enough on the bridge, and there’s been no punches thrown since that first time. When he turns to Spock after Scotty (or, God help him, Chekov) has explained something that would be incomprehensible even without the accent, Spock translates. He’s even lost about fifty-percent of the mild condescension. Jim can deal with the other fifty-percent; he’s had enough women berate him for his arrogance to understand a healthy pride in your own abilities. It’s the other times that bother him.

The first time it happens, it just, sort of, well, it happens. He's sitting on the bridge, and they're kind of talking, but mostly just barking orders at everyone who'll listen because it's a bit of an emergency, and Kirk's got something about crew morale in the back of his mind because he's a damn good captain. And he's thinking about making them laugh, but he's also thinking about making sure they don't all die in the next ten minutes.

As much as Kirk tried not to let himself be influenced by old Spock's memories of the future, even he had to admit that he was having difficulty. It wasn't any specific event that bothered him, but the whole tone of the bridge was different. Spock was different. In old Spock's memories, Kirk had felt the two of them like two halves of a single whole, two sides of the same coin. They worked together like a well-oiled machine. He barely had to give an order before Spock had already carried it out, often anticipating him even before Kirk himself knew he was going to make the request. But that was old Spock and his Kirk. This was different, and after experiencing that sort of connection, the difference was frustrating.

They had taught him all about the physical size of it in the Academy, of course; he knew that the Galaxy was about twenty-five kiloparsecs across, which was the length of the old Route 66 about 2 x 1014 times over. He'd worked that out once, doodled in the margin of his notebook in class, but he still hadn't really comprehended it. Because every time it was impressed on him just how monumentally vast space was, all he heard was the potential for new planets to explore, new life and civilizations to find. And while that was true, he had never really grasped that in between lay vast expanses of emptiness.

"If the Captain requires someone to monitor his diet and activities until he is more stable, I will volunteer for such a duty," Spock says, and that's where it starts.

"I am, as you know, aware of your relationship with your Captain. Were our people not so endangered I would not ask this of you. But with the future of the Vulcan race in dire jeopardy, I must request that you return to New Vulcan to take part in the koon-ut-kal-if-fee with a new mate of our choosing."

He merely can see that, in the course of their years together, he and Nyota will part ways, and his way will merge with the captain's.

Amanda has been keeping something from him; Sarek finds out why.

Jim quickly figures out he has to break the rules if he’s going to survive on the Enterprise.

There was something devastatingly cute about the mix of wide brown eyes, pale skin, pointed ears, and neat hair cut when packaged in a body barely over three feet tall and swimming in a blue science uniform top and dark undershirt that was entirely too big for his body.

Two years later, the pon farr finally catches up with them.

Detective Spock, born on Vulcan and resident of San Francisco, is assigned to the Midwest police bureau. I think everyone can guess what happens next.

In which the subgenre of pon farr fic is mercilessly and lovingly deconstructed, with Wagner.

He is four years old. His father is dead, his father’s people glad to be rid of the traitor. He has only his mother and his mind, and both seem liable to break.

Uhura hates James T. Kirk because he never seems to do what is expected. Things get messy when Jim makes Spock do unexpected things in return.

The Federation and the Romulan Empire have been on the verge of war for what sometimes feels like forever; this is the place where what passes for peace might end.

The answer is √π233/hy7. Has been for all three months of the first semester. Jim's not sure why the galaxy's best and brightest haven't realize that, but it's not his school, not his problem.

"I do not care even a little bit. Take Vulcan or go back to Tactics with your tail between your legs, but I've done you enough favors. Leave now."

Winona has all kinds of dreams for Jim's future when he's a boy, but not Starfleet. It's already taken too much from them, she tells herself, and as much as she loves it -- as much as she wouldn't give up space for anything -- she's not about to give it her boy, too. That's not really why, after a while, though. It's that Jim seems so angry, so ready to fight anyone who gets in his way. She thinks he doesn't need more weapons, more reasons to fight; he needs a home.

The Enterprise is ordered to pick up a Vulcan Healer and transport him to the new colony. Once there they are scheduled to remain and assist with the early stages of setting up the colony. Kirk's liaison is his 'old friend' Ambassador Spock, now known as Elder Sepak, who takes the opportunity to help Kirk and Spock become better acquainted.

"T'Pring. I know that the bond makes you desire further closeness, but do not confuse loss of self with being close. You are T'Pring, he is Spock, and the two are joined, but not the same."

She's a press secretary, a PR manager; she's the one who keeps them on-message. She's the one who takes the make-shift bombs from Kirk's fingers.

When he'd lost Jim, he'd thought that that would be the greatest death he would be forced to face; to endure.

Seven months into their five year stint aboard the Enterprise, Jim's meld with Ambassador Spock comes back to bite him in the ass.

Sarek does not always understand his son, but that does not mean he does not love him.

In a timeline where the Vulcans never allowed Earth freedom from their oversight, Jim Kirk doesn't fit in. All he needs to get away is a fast ship and a crew as crazy as he is; luckily, some things are universal constants.

AKA 'The One Where Spock Prime is a Matchmaker'; but be warned that it's as much about Spock Prime and matchmaking as TOS is about modes of technology in the 23rd century.

Should he tell Chekov that Kirk and Spock were living together? Chekov could keep his mouth shut, but -- no, this was one of those things that was too good to keep to himself and too fucking insane to tell anyone, even his best friend. If Chekov found out on his own, then they'd scream about it and never tell anyone; yet if Spock was being moved into Kirk's room in the middle of the night, the chances of their going public any time soon were fucking slim, if existent at all.

There's a reason New Vulcan doesn't have all-night wedding chapels, Bones, and it's not because they don't like Elvis.

Spock accompanies his parents to an Earth resort where Jim Kirk is a dancer. 'Dirty Dancing' redux.

Just for shits, as far as Jim can tell, he teaches him the Standard accent that makes Vulcan ears bleed with pain, the one that makes them forgive you because you're trying so hard, and the educated one that might make a Vulcan take you mildly seriously. Then it's on to different dialects of Vulcan and why you don't talk like this in polite company and why this accent makes Vulcans think you're upper class, even if you're really, really not. As a chaser, he adds in Romulan and how it differs from Vulcan, and how S'Fuckhead basically rewrote it from the first few grunts the first proto-Vulcans made. (Which is actually kind of interesting, but Jim would rather live on plomeek soup than admit it.)

He's been a good Captain. It isn't his own ego talking, although it does tend to echo across the galaxy on a good day. He's seen the peer reviews his crew sent in, seen the overwhelming praise that's been sent to Starfleet on his behalf. And yet here he is on his mostly deserted ship filling out paperwork to send them scattered across the universe because not one of them wishes to remain with him.

Spock, who has just experienced intense emotional compromise, has no desire to do so again. And so, while Kirk assumes the captaincy, he goes to his quarters and meditates. He finds the place within his mind where he built the mental shields that separated him from T’Pring. Behind those telepathic walls lie the remains of his bond. As he examines the shields for damage, he is aware that something is behind them. It flutters faintly, like a baby bird genre:fluffing its tiny wings. It does not feel like death – it feels, strangely, like birth. But Spock will not risk exposing himself to a broken mind link. Down that path lies madness. He doubles the barriers, reinforces his defenses between the shattered bond and his mind, and the awareness disappears.

The last day of the Enterprise's five-year tour is comprised of about 90% lounging, 10% other.

After the bar fight, Nyota thinks to herself that if this is what being hit on by Jim Kirk leads to, she’s very glad she’s never going to have to see him again.

"Commander Spock, we have located your son," the Vulcan lady on the screen says, which would be great, except Jim can tell by the look on Spock’s face that he’s never heard of this kid before in his life. "If it is expedient, the child will be sent to join you on the Enterprise within the week."

If Amanda had to pick a word to describe Sarek, it would be "genuine," or maybe "surprising."

Amanda Grayson raises two boys on Vulcan.

Detailing one of Amanda Grayson's first diplomatic assignments, which happens to be on the USS Kelvin.

"I am meditating on Logic. I left her on my planet."

And having it confirmed, that Spock was actually begging for credits, almost shocked him speechless again. But not quite. "What are you doing here?"
