Step sister and not actually related.
Cain refused to acknowledge her as a sibling because of her low blood (Aria's mother was a prostitute who was raised to the level of countess)
Cain is gross, but he ain't incestuous
i mean like tbh in my eyes their still siblings and like even if cain doesnt acknowledge her as a sibling, she sure does and im pretty sure shes feels uncomfortable. so like he gotta back tf off either way (/TДT)/
