“No, Leia was definitely not Luke’s sister circa TESB. There are deleted scenes that illustrate this in spades - as well as the Marvel adaptation of the film. It was a love triangle, pure and simple.”- this is a correct statement and there are plenty of articles in publications such as Star Wars Insider , Starlog , Cinefex , Fantastic films etc to back it up as well as the making of books by J.W.Rinzler . I have many of these publications in storage boxes and will have to spend some time digging them up .
