McSpirk

James T. Kirk/Spock/Leonard McCoy

Star Trek's command trio — heart, logic, and the captain who needs both — anchors one of fandom's oldest OT3s, with roots in the original zine era. McSpirk resolves the franchise's foundational triangle by keeping all three on the bridge and in love.

Spock is a uniquely frustrating Vulcan.  McCoy has known this since the day they first met, and yet, the hobgoblin still manages to find new, inventive ways of irritating him.  Today, he is lying in a crumpled heap on the ground, insisting that he and Kirk leave him behind. McCoy very well may have

The Falutero Affair

by ladydragyn

The Falutero created by Leonard, M'Benga and their team is a medical miracle bringing hope to the hopeless. It is probably the most important invention to the galaxy. Too bad some people want it and its creators destroyed.

Spock's Shadow

by Dreaming_of_the_stars42

Spock has always had a difficult time negotiating between his human and vulcan half. This sometimes leads to complex, and rather illogical, emotions that he cannot control despite his training. Jim is rather in tune with his vulcan but finds it hard to bring up his concerns leading to a huge misunde

Spock was a Vulcan. He wasn't supposed to have a soulmate. He certainly wasn't supposed to have two. Tell that to the anatomical drawings and quickly scribbled notes on his wrists. Or Spock has never drawn on his skin, leaving Jim and Bones not knowing they have another soulmate besides each other.

Spock could sense the Captain's worry radiating from somewhere to his left and several decks above him, as well as the doctor’s, only a room away, which was excessively potent from the closer proximity (and due to McCoy's natural caring tendencies).
