Just a quick story from Cissy's point of view about Bella.
Disclaimer: Obviously, I don't own Harry Potter. :P
It was the second night since Andromeda left us.
I was outside Bella's door. Where I felt numb and had shed only a few tears, keeping the Black's righteous manner, Bella had screamed. She had cried and broken objects. She'd blown up several muggle houses by accident because of her own anger - her insane anger. She had been the one to blast off Andromeda's name. She was the one who had ripped or smashed anything and everything she could in Meda's room. She had been the one to etch out Andromeda's face from photos.
Bella was the one who took it hardest.
Not father, not mother, not I. Not our cousins, though I'd never expect it from Sirius. I wondered if he even knew that she'd left, seeing as he was at the Potter's. Not Aunt Walburga, or Uncle Orion. But Bellatrix.
She had locked herself in her room now, and I could her weeping from the closed doorway. I'd have thought she'd be the one who had reacted like I, and I react like her; but no. She and Meda had always been close, too close for their own good seeing as Andromeda had become a traitor. I could also tell she was worried what her fellow Death Eater's would think. The Dark Lord's most trusted, her sister becomes a traitor and an enemy. Would Bella follow? Only a fool would ask that. It was obvious that Bella had become obsessed with her master and his cause.
I was too worried what would become of me if I knocked, and when I was about to open the door –risking my own life, truthfully- the door flung open. Bella stood in the doorway with blood-shot eyes, a tangled mass of curls, and tears rolling down her face. Before I got the chance to say anything, she grabbed my wrist and pulled me in her room.
"Don't you dare go the same way as her, Narcissa. If you do, so help me, I'll kill the pair of you. With no regrets and no hesitation. I'll make it as painful as I can for you, understand? If you dare betray me like her, I'll even try and get my Master to torture you. Are we clear?"
She hadn't released me, but had pushed me against the wall, her wand against my throat.
"Are we clear, Narcissa?" I nodded quickly; I could feel the force of her clutch drawing beads of blood. She looked me over for a few seconds before letting me go and storming downstairs, and because of the open window, I heard a faint crack from outside. Sighing, I threw myself onto Bellatrix's bed, and took in her scent from her rarely-used pillow. It used to be all sweet, and would keep me happy. Now, because of the things she had done on her master's orders, it was fairly sugary, but I could smell the bitterness and almost taste the blood she had spilt on my tongue.
And for the first time in years, I cried until I had no more tears.
I cried for Bella, for Andy, for my life. I cried for the fact that my (now only) sister risked her life every day fighting along side her Lord. I cried because I didn't know what else to do at that moment. And for the next half hour, I forgot I was a Black. I just thought about how I had already lost one sister to a war, and now I was slowly losing Bella. My Bella. My only sister.
And then I remembered how Bellatrix only belonged to one person now. She didn't belong to me. She didn't even belong to herself.
She belonged to her master, the Dark Lord. She wasn't my Bella anymore, she wasn't Andy's Bella, and she wasn't her own Bella.
She was his Bella.
