I last saw her wishing Derek well on his journey, Fritz is practically on the other side of the moon, i doubt she'll ever see him again, to be honest. She must have felt devastated after their little talk.
Now Listen here, the fact is that she would never choose to harm you or your soul, but nobody ever said she would love you either. You see, when push comes to shove It'll all have to fall back into place. Don't worry much about it, run your body down with some lemonade and stop fussing about Mary.
