Raised by the Dementors

Surprise!

Remember that I OWN NOTHING  except for the plot and Gemini ok???? The rest belongs to JK Rowling. (future me here, rewriting is a pain but I do this for you guys cause I love y'all so enjoy!)

Strands of her messy curly hair stuck out in unnatural angles as the woman walked towards her cell. Some of it stuck to her face with sweat and half-dried blood, an obvious sign of her struggle against the guards who dragged her into the prison. Her bare feet were stained with brick powder and her hands were tied behind her back as she was forced to walk, a wand held to the side of her head, which she tried to bite a couple of times. Despite her obviously bad situation, Bellatrix Lestrange had a smile on her face, more akin to the smile of the mad hatter than a genuine, sane smile, but a smile nonetheless. Her face looked sickly pale and her teeth looked more yellow than a slice of cheese, but the woman still hummed a happy tune as she walked towards her new, hellish home. Did she feel guilty for serving her Dark Lord? Of course not! So why should she mourn? Why should she cry for a man who she believes to be alive? Because Bellatrix knew the Dark Lord wouldn't die by an infant's hand, he was much more powerful than the world perceived him to be! This is why she would wait, as his servant, until he grew strong enough to return. The occasional demented giggle left her mouth as she walked, and such a creepy and familiar and dreadful laugh was bound to catch someone's attention. 

From the bars of his cell, Sirius Black saw the approaching Bellatrix Lestrange, looking more unhinged and (dare he say, uglier) than he'd ever seen his cousin. Azkaban seemed to have drained most of his strength, but he had enough to walk towards the bars and let out a series of quiet curses, watching as Bellatrix spotted him. She let out a manic laugh as she was tossed into her cell, immediately bursting in a fit of laughter on the floor. It took a few minutes for her to regain her composure, but once she did, she leaned against the wall separating her cell from Sirius', clearing her throat before speaking. "It's been a while, has it not, Orion? Fancy to see a blood traitor here! Though you do deserve it, probably for being so stupid and... yeah, stupid."

Even after years of not speaking a word to each other, Bellatrix still managed to push Sirius's buttons. "I thought you were the one putting people in cells and shamelessly torturing them? How does it feel to finally get put into place? Not only are you the insane sister but you're also in jail now! Couldn't even do your job as Voldemort's dog properly, otherwise, you wouldn't be here, Druella." 

The Black cousins, as much as they despised each other, could agree on hating to be called by their middle name. One for wanting to be apart from his family, the other for believing herself to be superior to her ancestors, who they were both named after. 

At the mention of Voldemort, Bellatrix punched the wall, sending dust flying through Sirius's cell. For a woman in Azkaban who had been starved and tortured, she had a great deal of physical strength. "Don't you dare speak his name, filthy blood traitor! At least I was not disowned by the family! I brought them pride, you brought them disappointment by running off with Potter and his friends. Isn't Pettigrew the reason you're here? Because he betrayed you? Pathetic." She laughed once more, sending them looks from the nearby prisoners. They looked more dead than alive as if laughs were foreign to them. Sirius almost felt bad for them, almost. 

His fist clenched when Bellatrix brought up Pettigrew and James, but he decided to keep his composure. His cousin knew how to rile people up, which would inevitably get both of them in very big trouble. "Listen, Bellatrix, there is no more Black family. I'm all that's left of it, and I plan on ending this cursed bloodline. Now, you can either accept this and reconcile with me since I am the only person who will be willing to talk to you about this new life we live, or you can go insane and never speak to family, or anyone, for that matter. You'll die alone if you keep up your manipulative behavior. Maybe learn from Narcissa and Andromeda while you're here because they are one thousand times better than you and you know it."
