time travel au where vader dies as he did in canon but wakes up as 19 y/o padawan anakin again, with his baby face and little braid and literally the weirdest vibes anyone has ever seen. the plot is not important. what is important is that obi-wan's padawan is like a thousand times weirder than he was before, which is saying a lot.
vaderkin: ... you are so young, my master. a young man, in your prime. and handsome. dashing, even. it is strange that i did not see it.
obi-wan, who is 100% committed to being the "boring old man" in anakin's life and registering in the negatives on anakin's 'hot people' scale: ???
anakin is so weird, so changed. it is definitely anakin - the force signature doesn't lie - but his claims that he "had a force vision, don't worry about it" don't really hold up because - what 19 year old has such an in-depth knowledge of military strategy, and with no war in sight? how has his youthful arrogance turned into cold assurance overnight, because yeah he's still arrogant as hell but he can actually back it up? his stare is even more unsettling and that is saying a lot, because as far as obi-wan knows (and he's been with anakin almost constantly for a decade) anakin shouldn't have the dead-eyed stare of a seasoned killer
and naturally the weirdest part is that anakin seems to have... a newfound crush on obi-wan? like he is making passes and keeps commenting on obi-wan's looks but with the energy of an older man at a school reunion telling you you've 'really grown into yourself' since he last saw you rather than an awkward teenager discovering what attraction is. anakin is really not subtle about it, but he's also not even embarrassed or starry-eyed and red-cheeked about it. anakin calls obi-wan a handsome young thing when he's never looked at obi-wan in his life before, and his usual 'moody adolescent' has turned into 'get those damn kids off my lawn', and why is obi-wan's very young padawan suddenly serving 'horny grandfather', obi-wan is a deeply confused man
