I have looked through a lot of posts on here, but cannot find any specific answer for this question.

Now, it's been pretty fairly established that due to having his memory wiped, C-3PO would not recognize Anakin/Darth Vader. However, it seems that R2D2 either never had his memory wiped - which explains his quirky behavior - or only had certain parts reprogrammed.

Does R2-D2 know that Anakin is Vader, either from scanning him or simply because he's been told? It seems that if anyone aside from Obi Wan would know him, it would be him.

  • Kenobi and Yoda both know that Vader is Anakin; ("How did Obi-Wan know Darth Vader was Anakin?") and R2-D2 was with both of them before setting off for Alderaan

  • Does R2-D2 really know anything? He's a droid, after all… he can store, retrieve, and analyse information, but can he know? Mar 24, 2016 at 11:25
  • @JanusBahsJacquet - If you read the novels, he's actually quite a clever chap and certainly the brains of the operation as far as him and C-3PO are concerned

  • @Richard No doubt about that (that's clear from the movies too); but is that actual knowledge? I'm being pseudo-philosophical here, but I'd say true knowledge requires a higher level of abstract reflection than AI is capable of, even in Star Wars (unless of course the novelisations make it clear that droids are actually capable of actual reflection and all that entails).

  • @JanusBahsJacquet - In the novels, he's (occasionally) quite eloquent and both droids are capable of abstract thought and quiet philosophy. C-3PO is permanently baffled by human behaviour though.
