Hmmm. So Comte, Vlad and Leonardo are purebloods and purebloods are born, so theu could in theory knock up MC and they would have a baby. So my thought is, WHAT IF that would happen AND then MC would actually turn to pure blood too? Or what if when having sex while her having her days she would turn to pureblood? So that is how purebloods would actually being made, having sex when human having her days. Which would be why there aren't so many purebloods because not many like having sex while on their days. I would LOVE to read a fic where one of them would have sex while MC is on her days and Boom, she turns slowly to pureblood. I especially would want to see Leonardo's reaction! And of course Vlad's and Comte's reactions too. Because i bet they wouldn't know about it either.
