Did Vader know throughout ANH that he had a son, or did he not find out till TESB and that his name was Luke Skywalker?
There was a Marvel comic where Boba Fett tells Vader the name of the person who destroyed the Death Star, but I don’t think it’s still canon.
Actually that version is the canon one, though the old EU version isn’t all that different, other than that (as far as I can remember) Boba Fett was never involved and it took much longer for him to find out.
