Ever since re-watching ANH a couple weeks ago, I've been thinking a lot about everyone who could've known about Vader's past life as a Jedi by the time of Ep. IV. First off, let's get the obvious ones out of the way: -Palpatine -Obi-Wan -Yoda There's no arguing with these characters, clearly. Where it gets murky, however, is when you take these into consideration: -R2-D2 -Owen & Beru -Tarkin -Yularen -Bail Organa With these characters, it's never explicitly stated they're completely in the know regarding Vader's alter-ego, so what do you think? Also, is there anyone I missed that I should add to the list?
