There might not be much to this, but it's something that's bugged me for a long time - why did Obi-Wan Kenobi change his name to Ben Kenobi when he went into exile? It's not much of an alias, is it? The character was only called 'Ben Kenobi' in the third draft of SW, then received the dual names in the fourth draft (he didn't really exist in earlier drafts, except as General Luke Skywalker). I can sort of understand why GL did it initially, out of universe - it adds a layer of mystery before Obi-Wan actually turns up & admits it's his name as if it's screamingly obvious - "Well of course I know him, you knucklehead, he's me!" It's also a somewhat exotic name, compared to Luke, Biggs, Owen, etc - it's one of the reasons I think the character wasn't intended to be originally from Tatooine. Luke continues to call him 'Ben' in ESB, although Yoda never does so, he only refers to him as Obi-Wan, as does Vader. Then when Obi-Wan's ghost turns up in ROTJ, Luke addresses him as 'Obi-Wan' for the first time. I don't believe this is a coincidence or an oversight. It's also quite telling that George Lucas would always refer to him as Ben in interviews back in the OT era. Then there's this: So the script describes the character as Ben, yet Luke addresses him as Obi-Wan. Same with the script of ESB. So what's the story? Was 'Ben' his real name, with 'Obi-Wan' being some sort of title, or Jedi given name? Or was Ben a name he adopted in between the PT & OT? I was really expecting something to crop up in the PT - one rumour was that a close friend of Obi-Wan's, a clone trooper, was called Ben. Is there even a limp EU explanation?
