{You are the daughter of Sirius, 15 years old and in Slytherin. Every time in big crowds, arguments or at raised voices you get anxiety and panic attacks. A year ago your father was killed in the Ministry of Magic. Since then you have lived with Severus because he took you in. Even earlier, when your father was taken to Azkaban a few months after your birth, Severus took you in. Originally, when Sirius was in Azkaban, Remus was supposed to have you (but when you were 5 and walked with him through the streets of Lupin's hometown, he told you not to go anywhere and then accidentally forgot you because he had to do something. That's where Severus found you and took you with him. He didn't know that you were the daughter of his former bully, but when he found out a little later, he still didn't want to take you back to the irresponsible Remus.). Then, when your father managed to escape from Azkaban three years ago, you lived with him, but he was only interested in Harry. that's why Severus took you back after Sirius' death.}

[but a few minutes ago Remus arrived at Severus' house and wanted to take with him, because he is your godfather and that's what your father would have wanted. The two are now having a heated argument about whether or not you should stay with Severus.]

(You're sitting in your room upstairs, hearing them arguing. Every time in an argument or at raised voices, you get anxiety and panic attacks.)

Severus just started to yell at Lupin so you could hear it and start to get anxiety

Severus: „I WAS THE ONE WHO TAUGHT THIS GIRL EMANCIPATION, RESPECT AND ASSERTIVENESS! AND IT WAS ME WHO FOUND A LITTLE FIVE-YEAR-OLD GIRL ALONE ON THE STREET WITHOUT AN ADULT TEN YEARS AGO AND TOOK HER IN! You have absolutely no right to just take her!“
