No, I create no symbolism from movies to anything real life. Even movies that are supposedly true stories or tv shows like Wayward. That missed the mark of the real story entirely. George Lucas has been asked about this to death. In his initial story Luke and Leia were supposed to be romantic. The pre-production edit for Return of the Jedi called for them to be brother and sister. She kisses him for luck before in New Hope before swinging across in the Death Star. She kisses him for real, clearly to make Han jealous in the sick bay in Empire. She never sees him again until the end of Empire in the Falcon, after telling Han she loved him. Where is the deep sibling romance?
