Pressing the Point by jedibuttercup
After the events of the film, Pike has a conversation with Kirk. I really love Pike's insights into Kirk - through him, we can see how Kirk has matured (which, you may notice, is a theme I favour).
Pike clears his throat. As entertaining as this conversation is, it's not why he requested Kirk's presence, and if the young man has to stand there awhile feeling the consequences of a day's worth of picking fights with opponents stronger than himself, so much the better. Maybe it'll give him a little more perspective.

This was the conversation I wanted in the film: McCoy and Spock Prime. Lovely.
"My friend Jim's got problems of his own," says McCoy. "They're either going to lynch him or promote him, and I'm not sure which would be the more dangerous proposition." He shrugs. "But that's Jim Kirk for you - had to go and save us all, just to prove he could. Him and that green-blooded sonuvabitch."
The Vulcan beside him chokes on his water, and McCoy's nearly ready to attempt his first-ever cross-species Heimlich by the time he catches his breath. "My apologies," he wheezes. "I believe I should pay closer attention when I drink at my age."

How McCoy ended up enlisting in Starfleet.
McCoy squinted at the sun, not even sure what the hell day it was. Or what month it was. He had a few credits left to his name, but not a hell of a choice when it came to living. He could've psychoanalyzed himself; he was still in shock, maybe. Or he would be, if he didn't keep anesthetizing himself to prevent himself from feeling anything at all.

Kirk's stepfather is usually shown as being a cock, but here, he's still irritable and frustrated with Jim, but he cares. I really liked this.
“You can do better than this,” he finishes. Shit, the kid's sucked all the fight out of him, and he hasn't even opened his fucking mouth. After a long moment of silence, he shakes his head. “Just go to your room, okay? Go.”
A little knowledge is a dangerous thing by hjpatience
The things Kirk knows, the things he doesn't know (despite, um, knowing them) and the things he doesn't want to know. A great look at the whole lot of them.
He doesn’t know about the euphemistically named “solvent production facility” that Scotty has set up in a storage room off desk 6. He has absolutely no idea where the forty percent proof booze came from that had the usually reserved Nurse Chapel dancing with Chekov at the last impromptu it-was-a-total-disaster-but-we’re-not-de

Yes, I'm all about the gen, but this is Spock/Uhura, and it's so delightful! Spock is so precise in his courtship, and yet romance is still in him.
Now he is ready for his final task: learning to cook her favorite meal. He believes this task will take 2 to 4 weeks, not very long in comparison to how to 6.2 months he has already required to identify his feelings and resolve to act on them. It is, however, potentially long enough for her resistance to Cadet Kirk to crumble. He resolves to learn to cook a bit faster.

...or six characters who didn't board the USS Enterprise. Cracky crossover joy. (With bonus S.E.T.)
Winchester grins, and Jim's suddenly taken back years, racing his borrowed car off the edge of a cliff, the sheer joy of speed like he'd never felt before. It's all on Winchester's face. For all his posturing and scars, he looks like a kid. "Nah, warp 6," he says proudly. "I installed a tetryon plasma drive system last year."
But Not Jim Kirk by jedibuttercup
Again, this is looking at how Kirk has matured over the course of the film's events, by looking at his earlier relationship with Gary Mitchell. One of the reasons I like it, other than the excellent characterisation of New!Kirk, is the references to TOS-esque things. Very nicely done.
"How do I ever get myself into anything?" Jim parried, with a wan attempt at his usual smirk. "Don't go getting all jealous on me, though. I don't even know if they're going to lock me up or commend me when we get back; Pike's talking promotion, but who the hell even knows."
Also, bonus fan comic here, another bit of fan art (so cute!), and anything by turntap2 here.
