Even if Marie knew about Adia's past, it wouldn't change what happened to her before coming to the Nexus. That fate was set in stone years ago and those weaknesses from years of trying to survive an apocalyptic world will always be present.

Adia's comment causes Marie to frown, no longer calm like before. There's no way she can tell Adia about her primal nature, that she must kill humans in order to survive, lest her sanity be lost. No matter how many good deeds she's done, nothing outweighs the need to slaughter. "Perhaps you're right..." It's a weak, cover-up answer, but one that tries to paint Marie in a fetal position, appear depressed and in sorrow.

"I wish him all the best in his endeavors. There's no hatred in my heart towards his decision."
