To observe Spock's vigil beside the Ambassador, I hesitate in Sickbay's recovery room doorway.

Both Vulcans are focused: heads bowed over data entry pads, fingers flying, their backs slightly turned away from each other.

Spock looks up first.

"Uhura said your father taught you to play chess, Spock."

"Indeed, I did."

The Ambassador speaks without looking up, and I catch Spock glancing at Sarek.

I hold my chessboard out, an offer. "I never had that opportunity."

"Indeed." Sarek's fingers come to an abrupt halt, and he looks up. "Perhaps my son…would indulge me in a game this evening."

"Certainly."
