It’s to show she’s a true Skywalker. True Skywalkers react the most emotionally over the deaths of people they’ve literally just met. Aunt and Uncle foster parents that you’ve known your whole life charred to bits? No reaction. Old hermit you’ve just met chooses to die fighting a cyborg? Big sad.
Lol, but also Luke hadn’t only just met Obi Wan he had met him in passing a few times, though yes he didn’t get to know him until a few hour (days?) earlier. However, I’d say that was the most important part of their relationship. Its when Ben openned up about being a Jedi and brought Luke closer than ever to his father than ever before in his whole life. And that is what Luke lost on the Death Star, The only link he had had and might ever have, to his father, plus the last remaining link to his home.
Luke showed his love for Owen and Beru when he rushed off to save them and when he found himself to late he was devesated to the point of generating the most touching peice of music in history out of the force. That says A LOT!
Also is this thread dead???
