Narcissa | Cassiopeia
She cannot do both, that isn't how things work. I'm not saying that you cannot spend time with her and hope that it is pleasant, but a member of our family does not choose to dilute the bloodline.
In that case? I came to Preya to avoid that terrible man Grindelwald, and now he is here. This place is...unpredictable. And I don't mean to question your regard for Lucius at all, but I would say that if you want to change your 'old path' for those reasons, instead of looking to Andromeda and her behaviour you should convince Lucius never to go near that man Tom Riddle, no matter what happens.
