There was almost too much information presented to him in Spock's memory push and Jim, with the limitations of a human mind, could not compartmentalize and analyze what he was seeing quite like the Vulcan could. However, a little effort and some trial and error, mixed with a little more creativity than Vulcans like to give themselves over to allowed him to replay the images slowly, like he was looking through data on a PADD.

His fingers even twitched slightly, a physical representation of what his mind was doing inside the shared space he and Spock had created between them.

A bonding link sounded fishy. How was it possible when one, Spock was only half Vulcan and Jim exactly no percent Vulcan? And about Uhura (and did that mean that Jim was going to have to look forward to whatever they did while alone)? And finally--

That girl.

Delving deeper, Jim saw her. T'Pring. The one Spock had been promised to until-- Well, he left Vulcan, likely, and started up his romance with their communications officer.
