Old Married Spocoy hanging out with Marirk (Marcus/Kirk)
Going on a double date camping trip and singing old camp songs.
Laughing when Nyota and Scotty show up late because Nyota had to take an extra day to drag Scotty away from the Enterprise for one weekend.
Leonard laying with his head on Spock's lap while Jim, Nyota and him point at all the stars above and try to name them all and talk about missions they might have been on. Spock pointing out that they're almost always wrong about which planet it is, but being really impressed when they actually get one right.
Scotty rigging up a cool toy to make cou tless smores at once and trying to be romantic and feed one to nyota, only to have her move past the offered food and steal a kiss, leaving him sputtering and embaressed and all the more in love.
Ben and Hikaru showing up on the last night because they had to hang back to help damora pack and move to the Acadamy for the start of her classes. Not missing the opportunity to join in and start having fun and laughing while Carol fills them in on all the fun ridiculous things they have missed.
