Remele being of higher blood than Tagora, can Tagora really sue her for art theft? I mean I'm sure the caste system established on Alternia wouldn't care or even let Tagora's accuse Remele

Tagora is just a Legislacerator, think that he’s part of a firm and Remele’s only one caste higher. Besides, Teals are stereotyped as the Law Guys, so they’re likely to be involved even with Violet affairs.
