Stiles younger sister (only by one and a half years) Maria was introduced to the supernatural world when she met Derek Hale. She also had a crush on him ever since. But she knows that they will never have a romantic relationship because of the age gap. One year later when Maria was a sophomore and Liam her best friend was a freshman (A/N: at the beginning of season 4) she was turned into a Heretic at around the same time Scott bit Liam and he turned into a Werewolf. Apparently Maria was a witch her whole life but she never knew. She always felt drawn to nature but she just thought that she liked nature and nothing more. Then Katherine Pierce came into the picture. She was the one who turned Maria. And she was the one who left her in the middle of the street after she turned her and said nothing except "If you wanna live you better get some human blood into your organism. Oh and.. you should work on your magic it sucks." and with that she vanished. Maria has no one of her kind in her city no one who could help her. All her friends were werewolves and not some blood suckers. The only one who could help a little was Deaton. He knew that I needed a daylight ring. Which she had to make herself with the help of an old grimmuar Deaton had from his old friend who died. In that grimmuar were stories about witches, hybrids, heretics all sorts of supernatural beings and a whole bunch of spells of course. With time she got better at being a vampire as well as a witch and controlling her emotions. Luckily she doesn't have any huge problems anymore which is good because she and her friends have other things, bigger things to worry about. The only thing she didn't know was the amount of lust she would feel whenever looking at or talking to Liams ex friend/enemy Brett Talbot which will become a huge problem because she didn't have to deal with her lust and horniness before since she wasn't attracted to anyone else the whole time she was a vampire.
