This is why it's vital to remember that Maria saved Star Wars in the edit and Lucas didn't even direct Empire or Jedi. Through the magic of fanon and death of the author and contempt for IP law I can just pretend Lucas never said that.

Plus, Lucas was constantly making up new shit and retconning things. I firmly believe he was just making the story up as he went along.

But yeah god I hate the "father son daughter" bullshit. Like why the hell would you even do that? It's so dorky and out of place with the entire rest of the story. ; p
