Poe thought Finn had died in the TIE Fighter crash too, except Finn was literally Poe's knight in shining armor who broke all his conditioning and chose to help Poe escape. While getting to civilization on Jakku, Poe spends a LOT of time thinking about this person who he knew for such a short time, feeling guilty for his death and feeling an indefinable ache that he wouldn't get a chance to be the ex-stormtroopers friend and show him all the good things about the galaxy and life in general. He falls in hopeless tragic 'too-late' love with the idea he builds of his rescuer who died saving him, and vows to make Finn's sacrifice worth something.

Then Finn's not dead! Music swells, happy reunion and Poe has all these plans based on the Finn he built in his head. Except actual Finn isn't the Finn in Poe's head, he's a real person, and Poe's image of him gets a reality check.

But sometimes, reality can be even better than an idealization.

Happy Finn/Poe ending please.
