No. I never said that and I never implied it. But Luke most certainly would have. If you object to the word “certainly” then put it this way: It is far more likely that Luke would have told everyone his father’s story than not.

Curious, but why do you think so? I ask because I’ve been thinking about this and I lean more towards him not. Luke to me is not the kind of hero to boast about his adventure and how he heroically vanquished evil/redeemed his father. I think back to the scene in ROTJ where he burns his father’s remains… alone. Why didn’t he have at least Leia, his sister, join him for the Vader bonfire?

Also, I think Luke would had been proud to say, in an alternative universe, he killed Vader if say Vader wasn’t his father or didn’t know Vader was his father. However, since Luke learned that Vader was his father, it’s something that struck him more emotionally. I mean, would you be proud to tell someone your father was some criminal? Someone whom was greatly feared and hated for unspeakable crimes against humanity?

Finally, Luke only told Leia who their father was. Luke told no one else. Leia told no one else except for the fact to Han that Luke and her are siblings. To me, this was a secret formed between Luke and Leia regarding Vader. Luke may have matured a lot over the trilogy, but doesn’t mean he’s not without flaws, and perhaps him being not open about his confrontation with his father is one of them.
