sure, canon's cool and all, but have you considered team ro au where sasuke is DEAD CONVINCED that Weasel is shisui and has this absolute vendetta against Weasel because he thinks Weasel's taking all his brother's time?
itachi is devastated, but can't say anything because, y'know, anbu secrets. accepts the kicks to his shins as punishment for being a bad brother.
shisui thinks this is the funniest fucking thing he's ever heard and absolutely does nothing to discourage sasuke. actively encourages it sometimes with comments like 'well, you've never seen Weasle and me in the same place....' and 'well, i am very good at clones. there'd be nothing stopping me from just making a clone in civilian clothes to throw you off....'
kakashi and tenzo spend way too much time trying to figure out how sasuke hasnt figured it out yet, considering kakashi&tenzo constantly walk around in full anbu gear without their masks. like, sure, itachi's good about secrecy and rules, but the three spend a decent amount of time together outside of missions, and kakashi isn't exactly, y'know, subtle. and sure, shisui frequently tags along cause where there's one bird boy, there's usually the other. BUT C'MON, KID!! itachi, your little brother is not built for recon missions. (he knows. gods, he knows....)
'your codename is literally just your name.'
itachi, staring into the distance: i know. but apparently, shisui is my best friend and clearly he did it to rub it in sasuke's face that he's closer to me than sasuke.
'you're joking'
'i never joke while on a mission, captain'
