He stood as Spock approached him. It seemed almost odd, seeing him so young after feeling the depth of age and wisdom in the old Spock. But the sage had been right; this young Vulcan was a different person, and he had to remember that. What would grow up between them would be its own thing, however it turned out.
Varying ratings, reboot, bond fic. This series follows the relationship of Kirk and Spock starting right after the (first) movie and does so beautifully. Love how it uses Spock Prime, the mindmeld and bonding.
