User blog comment:Seven Heavenly Virtues/Understanding Margarita: Overview, Gift and Sleepless/@comment-4698889-20140822091932

After taking the time to read this, I've finally gotten around to agreeing with your theories. Also, I'd like to add: What if, when this new "disease" hits, all the Sleepless people are desperate for a cure, Margarita SELLS them her poison at a steep price and markets it as medicine to make a profit? It's like a saying in America: "Create a need, then fill it."

However, I'm going to have to disagree with you on the possibility that Margarita wasn't aware that the Clockworker's Doll was spreading the fumes. Perhaps the Clockworker's Doll was spreading the vapor of a medicine/serum that GAVE people the symptoms of Sleepless. After all, it seems that Margarita, being the daughter of a doctor, also has some medicinal acumen.
