McSpirk: The Trouble with Trios

This is a bribe fic written for my companion, Bradley. It's a mashing of AoS and ToS and I've smudged some canon to make it work. (I know, ugh, but I wanted to make it to Bradley's specifics)
Things of note: This is set in a mix of AoS and ToS. The mechanics of the academy are more similar to ToS, meaning Kirk won't become a captain in two years, but rather the original 14. However, more like AoS, Spock is currently teaching at the academy after working under Pike. And, like AoS, he rejected the VSA. McCoy, in this, is older than Kirk, but less so than in the original. This ignores Kirk's years as an ensign and a Lt, and ignores the canon fact that Leonard never went to the academy. This universe slightly changes starfleet requirements for medical officers.
