@Svelandria, I quite agree about her actions being a product of her environment. I've had my own boughts of this kinda crap, so it's not like I have the right to toss her under that bus from
Speed. Rather, I thought her actions were complex and likewise fit into a larger sphere of drama. We
all have out own forms of "crazy/crazytown", yet we must each individually learn to work through/past said crazy. However, her sister's behavior & her parents horrible response to that behavior quite indeed produced said "drama" monarch reaction.
Moving forwards, both Greed & Chris offer the possibility of showing her that the narratives of her family are BS and she is indeed important in her own right. :3
@Simpleton, I likewise agree/concur with your analysis. A well developed character should have a combination of feelings/rationale behind their actions.
