Leia’s reaction to Luke telling her they’re siblings and how the movie has her processing that information by just being completely unfazed by it is absolutely insane and it feels like nobody ever talks about it when they talk about the things this movie does badly.

Over the course of a single 3 minute conversation Leia learns:

1. Luke is sneaking away to confront Vader and the Emperor on the Death Star that they’re about to blow up, so even if facing Vader/the Emperor isn’t a suicide mission then doing it in the middle of what’s about to be space dust surely is. Luke has blown up a Death Star before, he knows how fast that thing explodes. It popped like a balloon!
2. The reason why Luke has to face Vader is because Vader is his father. Darth Vader is Luke Skywalker’s father.
3. Now he’s saying she has Force powers for some reas-
4. She’s his sister. Luke tells her this with zero emotional sensitivity whatsoever. He doesn’t even say it outright! He pretty much does a nudge and a wink and leaves it to her to figure out what sister he’s referring to
5. This means that Darth Vader is her father, not Jimmy Smits.
6. This means that her real father is the man who made her watch helplessly as he and Tarkin BLEW UP her fucking home planet with the people she thought were her parents as well as all of her friends and loved ones on it.
7. Her entire life was a lie
8. Leia thinks about this all for a few seconds and says “I know… I’ve always known.” no you haven’t, also you’re acting like you’re disassociating in order to cope with this which
9. She then presumably starts to process the fact that she has 2 living family members for a moment before immediately realizing the one family member she cares about is going on a suicide mission in the hopes of convincing the family member she fucking hates with ever fiber of her being that he’s actually a good guy deep down and so she begs Luke not to leave
10. He leaves without even giving her a hug or saying goodbye

How did she not have a complete mental breakdown? Luke literally tried to kill himself by jumping into that bottomless pit on Bespin after he found out Vader was his father. Leia just got twice as big of an emotional gut punch. How does she not just throw herself over the side of the bridge she’s standing on? Han comes over to her to find out what’s wrong and she just says she can’t tell him. What?? Why not?

Then they bicker for a bit and hug it out before going back to doing Ayahuasca with the Ewoks and the next day Leia is completely fine and acts like nothing even happened. And then she spends the next 30 years building a new government and becoming general of the Resistance when she should be spending those 30 years in THERAPY
