@mostthingskenobi sent me an ask a little while ago about Obi-Wan and a tattoo, and I couldn’t help thinking there would be some kind of story behind it? So, here’s how I can imagine this going down:
It’s the end of a major battle (sometime around the end of S2), Obi-Wan has been pretty seriously injured, and his armor is just wrecked with blaster fire. Once Kix has everyone stabilized and they’re waiting for the medical frigate, the troops do as they do to keep entertained: new tattoos! For the Shinies, for the vets, and then… for the Jedi? Don’t you want one General? How about you, Commander? Ahsoka declines on the grounds that her skin coloration is still changing, and she doesn’t want to be stuck with something that’ll look weird once she’s grown up. Anakin makes himself scarce – Kix’s tattoo needle reminds him uneasily of the tool used to implant the microtransmitters into slaves on Tatooine, though he’d never admit it. Obi-Wan runs out of objections somewhere between when his painkillers kick in and about halfway through someone’s hip flask of Corellian whiskey.
Anakin returns to find Obi-Wan, passed out, with a half-finished Jedi Order emblem on his shoulder. He tries to explain to the troops that you can’t just tattoo someone when they’re unconscious, but they argue that this is clearly the best time, cause then you can’t feel it! And the General picked the design, they wouldn’t just do it without his permission. (Also, “Snips, how could you let this happen?” “Master, I can’t forbid Master Kenobi from getting a tattoo if he says he wants one!” “You can if he’s flying with no stabilizers!” “…Master?” “Drunk, Snips.”)
Obi-Wan comes to on the medical frigate and concludes that the tattoo seemed like a much better idea when he was drugged (something about his armor being ruined, so if he just put the emblem right on his shoulder he wouldn’t need it anymore…well, it made sense at the time…). But, by this time the clones are so tickled about General Kenobi taking part in their post-battle tradition that he doesn’t have the heart to have it lasered off right away.
