Continuity Problems

Ben: Your father was betrayed and murdered by another student named Darth Vader.
Luke: But... Darth means 'dark lord of the Sith' and is by definition a title used for Jedi who've turned to the dark side. Wasn't that a give away?
Ben: Well, his name wasn't Darth Vader at the time.
Luke: What was his name before it was Darth Vader?
Ben: Annakin Skywal... ton...sen. Annakin Skywaltonsen. Yeah, Annakin was a common name back in those times. Yep. I could go for something to drink couldn't you?
