Sulu! That face!
In my personal headcanon the device in Sulu’s hands is actually his smart phone and he is just texting Uhura about how adorable and hilarious Chekov is, and she is like, “I’M WORKING HIKARU. STOP TEXTING ME AND JUST DO SOMETHING ABOUT IT.”
(Because in the Enterprise in my head Sulu and Uhura are BFFs and they spend a lot of time talking about his feelings for Chekov because she is like “hahahahaha you finally are serious about someone and it’s a grumpy ridiculous Russian UNDERGRAD, you are so ridiculous bb.” Uhura, on the other hand, is the queen of having her shit together, so Sulu has NOTHING with which to reciprocally tease her, except maybe how hot she thinks Spock is, but she is like, “EVERYONE ELSE WITH EYES knows he is fine, Hikaru, HE PLAYS THE VULCAN LYRE, YOU CANNOT MAKE ME EMBARRASSED ABOUT THIS.”)
(Also they have a book club and he makes her watch every Errol Flynn movie with him and she makes him do drunk karaoke. It’s a beautiful Enterprise in my head.)
