im so confused with the comments i dont remember anythign abt her mom

I don't think we've been given much info about her mum yet. Just that she married Duke Sorfel as his 2nd wife and is implied to have been dead

so they didn't mention it either her and her other brother (i forgot his name but not the first wife's son) is from the same mom ?? atp i might just read the novel ┗( T﹏T )┛

Yep they have the same mom
