"I think about it as well." She then dropped the root stalks to the boiling solution, then gestured for Keith to grab onto the few spices to his side while she stirred for now. "Which is why I relate to her most of the time."

Before returning, Nathalie spoke about how she was rather compassionate to Mystique despite the ill-gotten deeds she had done throughout her life. 

Back then, she read so many reviews how they blamed Arnold for being too rotten and failed so badly as a father figure. Not everyone would even accept how he deserved to be called such a father.

Even when Athan's father would've been a lot worse, and possibly most of the noble families had such a mindset; they were rather glorified and warranted for their actions.
