"well, hello, long time no see isn't, *(y/n)*?"
Bellatrix revealed herself inside (y/n)'s room as she held a picture of the girl and Dumbledore from her graduation day and looked at her in a deep way in which one could feel her contagious madness throughout the room. In addition to Bellatrix's presence, a strong minty smell was prevalent in the place. It reminded her (y/n) of her years at hogwarts, remembering the bullying she suffered from Bellatrix, letting her anger take over her soul for wanting to end the life of the woman who had invaded her home.
"What are you doing here?" (y/n) decided to ask. Bellatrix starts laughing hysterically and answers
"I came to get you. Now that old man is dead and Voldemort controls everything." (y/n) couldn't hide the emotion of surprise that was already on her face and then in a desperate tone asks.
"Wait, what does YOU mean by that? Are you talking about-"
"Exactly." Bellatrix interrupts her and then continues. A smile was more than obvious on her face. She was excited to see (y/n) in a way.
"Dumbledore is dead and Voldemort killed him" the anger and sadness feeling mixed and intensified more and more in (y/n) and without thinking, she pulled out her new wand and before she could cast a spell, Bellatrix quickly looked for her wand but without success in finding it and finally throws herself in front of (y/n), leaving her unarmed and picking up her wand."A wand? You need a-" Bellatrix was startled to see the wand in her hand. And then she remembered the frustrating moment when she examined Dumbledore's lifeless body but could not find her wand to give to the dark lord, which earned her a great humiliation from her greatest master.
*flashback on*
"Incompetent!" Voldemort's voice echoed in her head and the sensation of the slap he gave her on the face made a single tear come out of her eye. All the Death Eaters looked at her with disgust.
"I asked you for something very simple, just to get the wand for me and you let them get it first.
Voldemort raised his arm and aimed his wand at Bellatrix"Avada...-" Voldemort was interrupted by one of his subordinates, Severus Snape.
"Milord, pardon the interruption. But I believe it is not necessary to kill your ally since this one has importance. Remember that Dumbledore was looking after a girl? Even the girl was close to him and must know something about the wand. Even Bellatrix knows her well." After Severus' words were finished, a smile formed on Voldemort's face, but it didn't look happy. It looked like a disgusted smile.
*flashback off*
Bellatrix was sure that (y/n) knew something about the wand but did not know how likely the girl was to possess it.
"My life would be so much better if you wouldn't get in my way." (y/n) pushed Bellatrix, causing her to fall to the ground and as she hit her in the face, Bellatrix's fury awakened, turning (y/n) over her body and hanging her, nearly piercing the wand of wands into her belly. Bellatrix could feel (y/n)'s fear rising and she loved being authoritative and in control.
"Now you will pay for everything you have done for me, mudblood" Bellatrix appears next to (y/n), walking out of her apartment and leaving a cloud of smoke around the place
