Well.... =Lucas= knew they were siblings; the actual Star Wars consisted of a 9 script arc that he had roughed out before deciding to start in the middle... And does anyone remember that very =FIRST= independant novelization done just after Star Wars shook the theaters? The one where things definitely were gettin incestuous in light of later information? Mmm, filet mignon. With ketchup. And french fries. With ketchup. And Diet Coke. With ketchup (and yes, I really have seen people blaspheme a filet in that manner)... How about catfish with ketchup!
