Ooohhh fascinating!! I always find it really interesting seeing how scripts change from first idea to final execution!
[Spoilers]
Selfishly, I'm glad you didn't go with the Amaia's death first idea since "ultimate freedom by way of suicide" has always left a bad taste in my mouth (looking at u Chopin's The Awakening), where it feels like surely there must be another way for this to go. I'm glad you ended the way you did! The parallels to the beginning were neat!
