She paid 15 times the price of the blue diamond, where did she get the money?! She was poor. Did she get a loan?! Does the bank give a 1,2 bn to random commoners even if the duke backs them uo?! Why did she have to pay 15 more times the prices when it was unnecessary and she was poor! It doesn’t make sense for someone who wants to be successful financially to waste a billion. I call bs.
