Narcissa eyed her interestingly. "Your offer is very much appreciated. And I did not want to imply that you had no manners, Miss Granger." Narcissa took a deep breath, glancing out of the window. "I will say it has taken me – and sometimes it still takes –  some time for me to overcome certain parts of my upbringing and societal prejudices, yet I know honesty when I see it. And despite the current conflict between you and my son... We are fighting for the same goal. He trusted and still trusts you despite the things that have happened - even if he has trouble admitting it - and the only goal I have is his well-being."
