Oh..

This ending is completely different from original novel and it's actually even better and makes more sense and omg I love how badass real Edith is.. I mean.. if I'm also the real Edith.. after watching the last Edith live her life using my own body I would give up on trying too. Tho but yes, it's a deep meaning, I mean 'give up on trying' from real Edith just mean she give up on her life and she even mentioned that world wasn't meant for her and it was a really sad statement
