No because I watch tos, and then I watch the aos movies, and I wonder if aos Bones feels like he's not needed anymore. Those movies focus so much on Spock and Kirk, and yes there are moments in which McCoy is there too, but sometimes, I wonder if Leonard sits in his quarters, knowing Jim and Spock are probably in one or the other's quarters, having a nice little chat.
And there's so much you can work with here. Because imagine, after McCoy risks his career, breaks his Oath of Hypocrisy, Jim doesn't thank him, oh no. He thanks Spock, and McCoy can understand why, but at the same time he doesn't get it.
So the two of them had been slowly drifting apart, after years of friendship. 3 years together as best friends, mind you, and Leonard feels as if he's been replaced by Jim's ex-nemesis.
But he still trusts Bones, still calls him by that wretched nickname. McCoy both loves it and hates it.
Because in the end, Jim's like the sun, and Leonard finds he can't remember a time without him.
Then they're ambushed by thousands of strange wasps, and McCoy can't even get to Jim. So he latches on to the next closest friend he has on this damn ship; Mr hobgoblin himself. He almost gets shot in the face but it's fine, Spock's there to shoot back. Then they're abandoning ship, and they land on the most beautiful planet (though he doesn't realise until *after* they've left it). Spock's hurt, of course, so McCoy helps him as much as he can. He hates that he can't help all that much.
Later on, he's flying a goddamned shuttle to catch Jim; it was all very mathematical and so very scary. He does save Jim, he somehow lands without crashing the damn thing, and all's well that ends well.
But later, when they're at that party and the three of them are standing side by side, Leonard knows he'll start drifting away again. For he was a measly comet compared to Jim's sun and Spock's moon.
And Leonard finds he doesn't fit into that equation much at all.
