Margot's note-writing has progressed by leaps and bounds. She's moved from the mystery notes (which tended to be both anonymous and nearly incomprehensible) to the slightly more targeted spy notes, to a new, clearly-articulated sort of warning/menacing note.
Key improvements include an identifiable target audience (i.e., anyone standing outside Margot's door), the correct spelling of 50% of the words, and the incorrect (yet completely readable) misspelling of the rest of the words.
