Savira: The Awful Truth About Her Past

Savira was called into Dumbledore's Office. She walked in and sat down quietly. Why had she let Javira do that? Why didn't she stop her? I mean, Delco and Xoto did kill Syce. Neither of them liked her. But still, she was their sister. Her thoughts were interrupted as Dumbledore entered.

"Savira, your behaviors today was totally preposterous!"
"I understand that Headman."
"And at the same time, I pity you."
"Huh? What was that?"
"So, Keira and Syce are your younger sisters, eh?"
"InuYana as well."
"I see. Tell me, Savira, why did you choose to be a teacher?"
"Because, there are dangers out there greater than Voldemort. Like my youngest uncle, and the one I was made from."
"And who would that happen to be?"
"My uncle is Anubis. And the one I was made from, I do not know his name."
"...Savira, I hate to say this but, I want you to resign as the Potions teacher."
"What?"
"Watching your fight this afternoon made me think a bit. And I've decided, to have you as the Defense Against Dark Arts teacher. After all, you seem quite good at it. Especially if you were able to make Voldemort flee."
"But... I... Hmm. Very well."
"Aren't you going to ask?"
"Ask what?"
"About Keira?"
"No, we may be sisters, but we rarely fight together. Same goes for worrying. We care for ourselves."
"I see. Well, you're dismissed!"
"Thank you, Headmaster."

Savira stood and left.
