There’s a scene in The Empire Strikes Back that shows Han and Leia arguing in the tunnel (the clip starts at 6:00): https://io9.gizmodo.com/a-look-inside-empire-strikes-backs-anniversary-antholog-1845487070. You’ll hardly notice it, but towards the end of that scene, there’s a character who walks out. Believe it or not, he has a name and a recently published story about him. His name is Chase Wilsorr, and the fact that a story has been written about him shows that in the Star Wars universe there is no such thing as a minor character. Even someone who is on-screen for one second can end up having their own story. The Gospels are filled with people who briefly appear, and yet how many of us know their name, story, or roles? Who is Joanna? And who is Susanna? Characters such as this—and specifically, female characters—may not be very well known, but they play important roles!
