I read the manga but i noticed something in the anime. At the beginning of the anime when Oz has a hallucination near Lacie's grave (Of Alice trying to kill him, saying things like "i'll never forgive you. i'll kill you" etc etc. ) BUT THEN throughout the anime she says things like " I don't like anyone who gets to close to him. I hate Glen, he took him away from me."
sorry this is so confusing, but yeah. :P
