One I realised when re-reading The Titan's Curse
Nico wasn't the only LGBTQIA+ di Angelo sibling.
I think Bianca joined the hunters of Artemis because she had just come from facist italy in the 1930s and was scared of being put to death for liking other women. She didn't know about how that wasn't a thing anymore, and when she found out she would be safe and with other women (wink, wink) she joined straight away.
