Random Headcanons no one asked for, Bonus Round
•Luke and Leia actually find out they share a birthday pretty early on, but considering neither of them actually has a reason to suspect that they’re long lost siblings, they don’t think much of it besides “birthday buddy!”
•Luke has never done much for his birthday while in the Alliance. He got the day off from chores back on Tatooine, and if the crops had been good sometimes Owen and Beru could scrape together enough to get some kind of cake. On his 17th birthday Owen somehow saved enough to get Luke a replacement part for the T-16. Celebrating without Owen and Beru, even if theirs were small and not terribly festive by some standards, just feels too weird for him.
•Wedge decides fairly quickly this will not do at all and organizes Giant Group Birthdays for the pilots, going by month. This starts to catch on with other branches of the Alliance, and bi-monthly birthday gatherings become a thing.
•After finding out they’re twins, Luke and Leia make a point of trying to spend every birthday together, even if it has to be via hologram.
•Poe Dameron has birthday parties for BB-8. C-3PO thinks this is precious and will not hesitate to say so. Leia is very tired of Threepio “hinting” that BB-8 would look very grown-up with shiny gold plating.
•Chewbacca can out-snark anyone, anywhere, hands down. Once he and Han ran across a gang of alien pirates whose leadership was determined by a Trial of Insults. Chewbacca got annoyed with their captain and accidentally ended up taking command of a pirate galleon. He and Han eventually absconded with a treasure map, but the pirates were too impressed by the Wookiee’s Snark Power to be mad.
•Lando writes poetry, but he’d be much too embarrassed to let anyone read it.
•Luke knows a lot of code-songs he learned from his aunt and uncle while growing up. (Because I like to imagine they helped slaves escape, much like in some of @fialleril ’s writings), and he teaches some of them to one or two Rogues, Leia, Han, and Chewbacca. The secret directions embedded in the lyrics save lives more than once.
•Maintenance crew on the Executor has an entire wall of tally marks for every training droid Vader had totaled. There’s a different wall for people he’s totaled, with names rather than tallies. It’s probably not safe to keep a memorial, but no one’s told them not to so far.
•Piett started out just drinking tea in the morning before starting his shifts. The longer he deals with the unique brand of weirdness living on the Lady Ex brings, the more calming tea (or occasionally strongly caffeinated tea) he requires. He’s up to four cups a day and steadily rising.
•For Leia’s twenty-third birthday, Mon Mothma gave her a hologram she’d been keeping of a younger Bail Organa with Senator Amidala and a young Mothma all smiling. There’s someone in the back that looks like a tall Jedi, but Leia can’t be sure. She and Mothma mourn a while, but the catharsis is good for both of them.
•Every time the Rebels move to a new base, Rogue Squadron makes sure to paint a rough portrait of Bhodi Rook somewhere in their assigned hangar, whether on a ship or a wall. There are memorials to all the members of the Scarif Mission, but Rogue Squadron always has an extra one for Rook. “Because he’s the pilot.”
