To be fair, Leia wasn't Luke's sister until writing sessions for Return of the Jedi. Luke's sister was going to be a new character, but, now that there was only going to be that one more Star Wars movie, and not three more after it (Luke movies -- not even the Prequels that he also wasn't going to make), the job ended up getting foisted onto Leia, being one of only four female characters with lines up to that point -- and of those, one was Beru, who was out for age, squick-factor, and barbecue reasons; and another was Camie, who was cut from the released film, so cna be considered moot (though I kinda like the idea of her turning out to be Luke's sister). So, really, it was Leia or the "stand by, Ion Control" lady.
