Jealousy is one of the most common emotions that can be felt through everyone in the world. Even throughout the inhabitants of Hogwarts School of Witchcraft and Wizardry. Though there are some students who believe that the Slytherins are not capable of such emotions. Jealousy in the Slytherin house would make others proclaim that they can be normal or be able to be trusted. But one inhabitant of said household seems to beg to differ.
Narcissa Black, the youngest of the Black sisters, glared across the Great Hall at her cousin, Sirius. He was laughing along with his friends, the Marauders and not giving a care who heard him be free of his family. He and James Potter seemed to be the closest of the four friends and the feeling of intense hatred didn't befall amongst them. There are times where she wished with all that she carries that her family could be normal and not bind to the dark ways like those of the Potter household.
She could understand having freedom from a house that didn't accept that you were different but knowing that you will not be able to have support for your misgivings was not something she could live with. Family is the web of closeness that isn't supposed to break so why did the Blacks seem that they could bend the rules?
Rules defined the Blacks and now she wonders if it was worth it discrediting views that are different from your family. There was a churning inside her belly that made her want to throw up but she held it back as she quickly ran her small hand through her hair. It seemed truly unbelievable that she could be jealous of someone that disowned themselves from them.
If only she was able to do the same. She would be able to experience the sense of freedom that holds Sirius together. But she couldn't. As the youngest member in the Black family she had to abide by rules of maintaining a position of becoming arranged to the Malfoy heir. The head of the house would eventually be Regulus and she would have to follow his ruling among those of her husband. Be seen and not heard.
Thus the curse onto the youngest.
Freedom would have been nice.
