the differences... mostly lie in that valencia is at heart a very paranoid person due to fighting space horrors and shit. and also just like. being raised under the Order/harmony... arguably following the harmony should be more generally accepting of things around her but alas! god assigned ocd
the aggression/manipulation/suspicion manifests like 75% of the time because of or in the presence of dan feng though she IS just kind of an angry person at heart for various reasons. but dan feng makes her worse for sure
scarlet on the other hand scores overall lower in those because the people around her are not actually encouraging her to be her worst self at all times lol
risk-taking/grandiosity is slightly more with scarlet though just due to the fact that she will act on impulse in many ways that valencia absolutely would NEVER and also just thinks like. she's gorgeous and has swag. val either does not or does not care
