Nico and Serafine having an older sister is the greatest headcanon I’ve heard in ages and I cannot stop myself from imagining it.

Just them having this older sister who is thought of as being the calm and reasonable one, which is an assumption that has lulled many a victim into a false sense of security because, in actuality, she is just as dangerous. She is nice and polite with an innocent face and ladylike manners; but she also thinks that everyone is expendable apart from Nico and Serafine. To her family is everything and she takes her role as the older sibling very seriously.

I cannot stop thinking about this and their relationship and childhood and I will be thinking about this all weekend now.

Thank you for your wonderful headcanons.

Yeah its such an interesting dynamic now that I think about it... this is the kinda stuff I like exploring ....

I like the idea of her being slightly more "dangerous" bc she is so fierecely devoted to her siblings that she'll do and has already done very awful things (tm) to keep them safe, and she hides this streak well with a polite, reasonable facade. Probs removes her accent and country mannerisms entirely when speaking to "outsiders".

Heck she may have been more of a mother figure than simply an older sister. Parentification at a young age and all that, even if shes only 3 or 4 years older .... abandoned by their parents either intentionally or by circumstance and left to be the Protector and the Grown Up .... food for thought
