10 Star Wars Details Only Explained Outside Of The Films
Information we don't NEED to know, but that's still nice to have anyway.
Star Wars has always had an expanded universe, ever since the beginning. The only difference between then and now is that Lucasfilm actually acknowledges that its extended universe exists nowadays.
Back in the day, if you brought up to George Lucas that Dark Horse Comics had Han Solo teaming up with a big green bunny who was also a certified badass, he'd... well let's face it, he'd kick himself for not thinking of such a thing first.
But the increased prominence of the expanded universe comes with a double edged sword (or lightsaber, if we're being accurate). Because now directors and writers will dedicate entire plot points to referencing stuff that will or has already been explained in material outside of the films those references appear in. Sometimes it's harmless extra bits of lore or fan-service; other times it's major plot and story developments.
These story details may not have been vital to the stories they were attached to per se, but surely there was room enough for them in the actual movies.
10. Luke Getting A Girlfriend - Heir To The Jedi
Because of the Jedi having that asinine law about not being allowed to get married, you rarely hear about Jedi having love interests, and if they do, it rarely ends well for either party. You would think that Luke, not being aware of this rule at all, what with the other Jedi being dead, would have a bit more luck. Sadly, no such luck for poor Luke.
Set between A New Hope and The Empire Strikes Back, Kevin Hearne's Heir To The Jedi saw Luke falling in love with a rebel engineer named Nakari Kalen. Being a farm boy from the middle of the desert, Luke of course knew absolutely nothing about interacting with a really cute girl, making for some adorable interactions.
But of course, if Luke was happily married to a badass rebel engineer, then Rey likely would have found him in much better conditions in The Last Jedi. Luke and Nakari's story ended in tragedy when she was murdered by the main villain of the story.
This detail sits at the bottom of the list because you don't really need this story to understand the movies. Don't expect this to last much longer.
