When Jim ends up as Spock's assistant as punishment for cheating on the kobayashi maru test, they quickly become close friends. Where will this relationship lead them?

(Basically a bunch of tropes and probably some angst)

Sent to Nimbus III on an errand of doomed diplomacy, Sarek has a chance encounter with a Klingon, Councilor Gorkon. Before he can get very far in negotiations, however, Sarek is forced to return to Vulcan upon the unexpected death of his son by Khan's hands.

As he struggles to understand the moral implications of the Genesis Project, Gorkon decides to accompany Sarek and Amanda back to Vulcan for his own mysterious reasons -- even as the Klingon Empire prepares for war.

And then of course there is Curzon Dax -- a young man coming to Vulcan in the midst of an identity crisis. Paradoxically he is old enough to remember 150 years worth of one Vulcan family's history, and unlike Sarek and Amanda, he doesn't feel especially bound by Vulcan cultural taboos to keep his mouth shut.

During their strange time together, Gorkon's unexpected wisdom leads to some revelations concerning Sarek's relationship with Spock and his opinions of Spock's bondmate, and helps guide Sarek's actions as Sarek makes plans to visit Jim on Earth.

Tapestry series.

Spock is held captive in a Cardassian facility and tortured for information. The only way he bears it is with the knowledge that at least Jim is safe. Unknown to him, they are forcing Jim to watch everything they do to his first officer.

This is going to be a multi-chapter fic. And it will be dealing with very dark themes. Darker than Finding Spock. Please heed the warnings if you are easily triggered.

It started with pon farr, and the forming of their bond on an isolated world.  But on their return to the Enterprise, they begin navigating the twists and turns and bumps of a new relationship, two strong personalities testing boundaries and struggling for balance.  Then Starfleet orders Kirk and Spock to negotiate a treaty with a potential Federation member and at the same time be an example of Federation tolerance.  Once on the planet, they find that things are not as they seem.

Unable to escape Apollo, Kirk and Spock agree to a quest to win the freedom of the entire crew.
