The Enterprise was fully repaired and they were underway in their new five year mission by the time Jim thought to ask about the Tribble. Honestly he had given little thought to it after finding out how Bones had figured out that Khan's blood could revive him. As it was he only remembered it thanks to a report from a nearby Starbase saying they finally were able to get a Tribble break out under control.
The Captain sat back in his chair on the bridge after reading the report and with a thoughtful look glanced around at the crew members as if he would get the idle curiosity solved by just looking. After noticing that Spock was still not back on the bridge after being called to the labs for a brief look at some experiment, Jim turned to face Sulu. Most wouldn't know about it but the Helmsman was surprisingly well informed of any gossip around the ship. Jim suspected it was because of Chekov but had no proof just yet.
“Mr. Sulu, you happen to know what happened to the Tribble Bones was experimenting on?” He asked with a smile, sure that the other man would know. Instead he was surprised to hear Sulu respond with “No Captain.” and a slight shrug. Jim blinked then looked over to Chekov who had turned to Sulu at some point. “What about you Mr. Chekov?” The teen genius shook his head with a look that reminded Jim of a puppy denied a treat. “No Keptain, I haven't heard anything about it.”
