Agreed. She loved 14 lifetimes actually, but since she was locked up and unsocialized for the majority of them, I think it makes sense for her to still have a childlike mindset. She wasn't allowed to learn much and had no way to progress mentally since she was constantly stuck in her teenage body for all of the other lifetimes which I like to think might keep her mindset equal to that of a teen as well. I think it'd be more of a shock if they made her have the mindset of a 70 year old when she never got to experience life in the same way that others would. Imo it makes sense that her mental growth was stunted up until now, if for nothing more than as a defense mechanism
right? but, well, it's amazing how she isn't numb yet. like an expressionless doll. I haven't even finished this lifetime halfway and I'm dead inside already.
i can only imagine how torn she was for 12 lifetimes that she still has a childlike innocence and hope for being loved. her mental age could very well be over 70, considering how long she got to live in each lifetime
sincerely hoping I'm not reading too much into it and it's not just lazy writing
