R2-D2 has seen it all. The loveable droid made his chronological first appearance in Star Wars in The Phantom Menace as part of the crew on Padme’s Royal Starship, going on to be Anakin Skywalker’s astromech droid, Luke’s buddy in the original trilogy, and finally a key part of the story of the sequels. R2’s rebellious behavior is often chalked up to him never having his memory wiped, granting him a distinct personality many other droids lack.
But, as many fans have pointed out over the years, if R2-D2 can remember everything from the prequel era, why didn’t he tell Luke all about Anakin Skywalker, Padme, and the rest? Fans are debating the issue, asking why R2-D2 doesn’t appear to recognize Yoda (a pretty distinctive little dude) when they meet in The Empire Strikes Back?
