@Toshii she has been consistently trying to avoid engagement with themt hroughout the series right from being picked by them in the orphanage... She can't outright just ignore them so she does her best to maintain necessary communication but thats all there is. She recognised that they can't understand her unwillingness but whether they remember or not, it does not take away from the fact that she was abused by them for an entire lifetime, of which they have no memory and she can't bring it up.... She touched the unnamed only because she was trying to die not gain more power.... Forgiving someone or letting go of grudges doesn't mean you gain back the part of you that you lost or the trust that was so utterly shattered. She has no familial or positive feelings for them. She feels what she feels and doesn't owe anyone the right to make her feel like she needs to make their life easier. She is polite, minding her own business and doing her duty to save the world. She doesn;t want to discuss what happened a lifetime ago because she was burned and they can't treat those scars. The end.
