I love Remelia so much, and I adore the contrast between her current self and her 'OG' self. It's truly an ingenious way to show what kind of person Remelia is. She's an incredibly dedicated and loyal person who only craves love and acceptance and we can see that in how she was more than ready to completely destroy the world for love when everyone abandoned her, but did everything she possibly could to save it instead even when there was only one single person who cared for her.
All she needed was someone, anyone, to care for her and she would've fought the entire world for them, but in the original no-one ever did and she suffered for it.
