I figured something out a month or two ago: Princess Leia does not get to live a happy life.
Popular culture has always defined the term “princess” as a helpless or hapless royal heroine, a damsel in distress, a fashion model. And pop culture dictates that a princess must go on to live “happily ever after,” either by marrying a more or less royal Prince Charming or by asserting her female independence. The term “Princess” looks superficial on Leia, but she lives up to her title in so many ways.
