I find it lowkey hilarious how Flora quite fits the cottagecore lesbian aesthetic and the colors of the lesbian flag visually, and Helia has a feminine name, so there's this theory that he was supposed to be a female character at first but was changed so Flora wasn't left out and also had a boyfriend, like other Winx. As far as I know, it isn't anything official and just a theory based on his name and a little more feminine features than other specialists (long hair, face), but these two things put together still are funny to me.
I watched Winx Club as a kid, ofc I was destined to be a bi disaster with high standards and love for people embracing all their traits, whether they're seen as traditionally masculine or feminine.
