Being the youngest of four girls, your older three sisters were always protective of you and expected you to be the angel of the family, which for your family was far from angelic. Normally you fit into that stereotype, you obeyed every rule and order from your parents, were a proud Slytherin like all three of your elder sisters and were dating a pureblood Slytherin. Bellatrix, although a little eccentric followed your parents' ideals to the letter unlike you who outwardly supported their ideas but had no actual care for blood status. Andromeda was the opposite, she was kind and loving and also burnt off of family tree due to marrying a Hufflepuff muggleborn. You secretly wrote her letters, loving your sister regardless of who she was married to. The youngest of your sisters Narcissa had just graduated from Hogwarts and was engaged to Lucius Malfoy whom your parents adored.

You loved all of your sisters but with Andromeda banished and Narcissa away living with her fiancé when you needed someone to turn to about your life, Bellatrix was the one you needed to go to. Although she was married and had a home with her husband, their home was next door to your parents' home, so it was not an issue for you and your boyfriend Y/B/N to get there to speak with her. He was apprehensive and stood behind you, knowing of her outbursts and danger she could cause. The two of you made your way to the lounge where Bellatrix sat.

"Bella," you smiled softly, rather scared of how she would react, but you knew if she was supporting you when you told your parents, they'd be a lot nicer about the situation.

"Sister," she grinned. "What do I owe the pleasure?"

"Um... we need to tell you something," you whispered as your boyfriend hung his head, too scared to make eye contact with your sister.

"Do sit, sister," she said pointing to the sofa opposite.

You gave her an awkward smile as your sister looked between you and your partner.

"Speak," she laughed maniacally, allowing her nails to play against her chin.

"Bella-"

"No, him," she said cutting you off.

Your boyfriend looked fearful but gave you a worried look, knowing he would have to do as she wished so that he didn't anger her more than what he would say would.

"Y/N," he paused. "She... um... she's pregnant."

Bellatrix's eyes darted to you before the crazy glimmer hit them. She grabbed her wand and dove towards your boyfriend, pushing the end painfully into his throat.

"You got her pregnant?! What were you thinking?" She screeched.

He jumped back as far as he could into the sofa but there wasn't any escape.

"Bella!" You exclaimed pushing her back.

"You've not even left school," she spat.

You were in your last year of Hogwarts, home for Christmas, with your eighteenth birthday being at the start of the school year.

"I know it isn't ideal, but things happen," you sighed.

"At least it is a pureblood," she huffed putting her wand down. "Does mother and father know? Or have you told Cissy and the blood traitor?"

"I came to you first," you whispered. "I'm scared and I need my sisters."

Bellatrix let out a sigh. "You had ruined your life," she stated. "But I shall help you raise the newest child to the House of Black as any good sister would."
