Third person pov.
"Why did you save her, Severus?" Dumbledore asked Snape, who was standing in front of his desk.
"It was my first reaction. Saving a student seemed logical to me. If everything works out well, my position will not be questioned either," he explained himself.
"She is a very talented and as we today learned powerful witch. She will be very useful as a second spy... I also belive that you are able to judge, if saving some one could risk your position close to Tom. I have faith in Miss (y/l/n), that she will be able to maintain herself and be a good double agent, but incase she fails you won't be able to help her," Dumbledore told Snape.
"I wouldn't bother to anyways, it was pure instinct," the potion master told him looking dead into the headmasters eyes.
"She has always been very kind to you, sassy but kind," the headmaster told his teacher.
"It must be part of her nerv wrecking personality," he shot back.
"This personality traid will be most useful, she is always critical and sees things that don't meet the eye right away... Once you have fulfilled my request we will need it," Professor Dumbledore said.
Snape looked very unsatisfied with that. The request Dumbledore made was simply horrible. Not even (y/l/n) would still trust him after that. He himself wouldn't, because that was a wanted side effect.
Snape would do anything to protect this school and the dunderheads wandering its corridors and so he did today once again, but this time it hadn't been Harry Potter or one of his insufferable friends.
"I decided she will be a Black," Dumbledore interrupted Snape's thoughts.
"A Black?" Snape raised an eyebrow.
"Indeed," the unwanted daughter of the bloodtraider Sirius Black. Sirius never had a commited relationship. Now we add that she had been an accident, a product of a quick affair. Her mother might be a muggle but her father's blood is pure. Her mother never told her that, which is why she believed she was a muggleborn. Once she discovered her father was indeed Sirius Black, by getting her birth certificate into her hands, she decided to join the dark lord, because she hates muggles because of what they did to her. And even though she is sadly part muggle she will help the dark lord to fulfil his true destiny and rule above all.
Tom will see this story in her memories and he will see himself in her. His mother was a pure blood his father was a muggle. He will look over her halfblood status and take her in as on of them. Being as close to his believes as one can be because he knows, what he believes is her position," Dumbledore concluded.
"Because some parts of this story are true, like Sirius never being committed and her having bad struggles with the muggle in her live, it will be even more believable."
Snape flinched. "Struggles... Has her mom cocked her noodles too short?" he sarcastically snared.
"Beelive me Severus, there is more to her then meats the eye."
"Your background story is actually very logical comprehensible, the dark lord will believe her, if she plays her part well."
"I hope she will," Dumbledore replied.
"You should get some sleep now, Severus. I believe you've ordered her to your office at three o'clock. You should rest until then."
"I believe I'm perfectly able to decide myself when it is time for me to rest," Snape replied.
"I will plan out the next lesson now, headmaster," he said while leaving the room.A/N: As you may have noticed I'm into full on writing mood... I hope you liked this fairly different chapter stile. I won't use the third person pov too often, but it can be very important to get information like this into the story... 🙃 PLEASE tell me if you liked that pov (I really wanna find out... 🤣) and if you also liked the content of the chapter feel free to vote too.
