Yeah I've had a rebuttal rolling around my head in defence of the OG trilogy, really all those characters are technically Just Some Guys, it's not like they planned to always have a chosen one who is a Skywalker from the beginning, and Luke wasn't even a prophecy child like all his forebears, if it weren't for Leia looking for Obi-Wan, Luke would probably be in spacefash academy training to be a pilot and none the wiser about his origin
