Okay I just came up with a headcanon
and now I’m a mess. Let’s just imagine that scarf - the scarf that Hermione left in the forest for Ron to find - was a bit more for Hermione than just a scarf. It’s been with her for years, since she was a little girl, and carries bunches of happy memories of her childhood, her family, the way her world was before the war. So it’s incredibly precious to Hermione, it means the world, reminds her of her parents, of better times. And yet she leaves it in the forest although the chance for Ron to find it is tiny. She literally leaves a part of herself behind for him. A part of her stays at the place where he had left, waiting for him to find her.
“You…you told me once that you weren’t a hero. Umm…
There were times I didn’t even think you were human, but let me tell you this. You were the best man, the most human…human being that I’ve ever k n o w n.”
