The only part in there that really bothers me is the whole "Threepio was Anakin's droid all along, and Artoo was there too" bit. Poor old Threepio gets his mind wiped, and apparently Artoo is just happily feigning ignorance for the rest of the series.I think that's a stretch. There was no logic to it. I reckon that when Lucas made Star Wars (IV), he did not plan that Anakin had grown up on Tatooine. Tatooine was envisaged as an out of the way world nobody had every heard of. Anakin's history came much, much later.
