Where Kirk and Spock get turned into 6-year olds; Spock is quiet and curious, Kirk is loud and protective, the crew is amused and McCoy is at the end of his rope. :D

AU in which Spock grows up on Earth and meets Kirk as a kid. A series of snapshots of their bond and its growth over the years. In this installment, you'll see the boys at ages 5 and 8.

“Commander Spock, we have located your son,” the Vulcan lady on the screen says, which would be great, except Jim can tell by the look on Spock’s face that he’s never heard of this kid before in his life. “If it is expedient, the child will be sent to join you on the Enterprise within the week.”

Spock met Jim when he was 7 and Jim was 6. It has since been generally agreed that this was a mistake (or: the one where they grow up together and things are simultaneously better and worse for it).

"Commander Spock, we have located your son," the Vulcan lady on the screen says, which would be great, except Jim can tell by the look on Spock's face that he's never heard of this kid before in his life. "If it is expedient, the child will be sent to join you on the Enterprise within the week."

"'Spock,' Jim breathes out, completely overwhelmed by the gesture—not quite believing that Spock knows him so well, that's he's already started researching, that he trusts Jim with a member of his own endangered species." When Jim gets it in his head to adopt an eight year old Vulcan, Spock presents a logical solution to the issue of Jim's humanity: marriage to a Vulcan citizen.
