(A/N: Sorry this one's so short, but I figured this scene needed to be its own chapter. Wasn't really sure how to make this work, but I tried.)
That night, while Snape was grading papers there was a knock on his door. He looked up and standing there with a small smile on her face was Sarah. She had a blanket draped over her shoulders and was wearing a pair of her black jeans and a black turtle neck.
"Hey," she said softly. "It took a while, but I finally persuaded the nurse to let me go." Snape nodded and stood up. "Look, I know you heard about my... issues..." she stopped for a moment to regain her voice. Her vow not to cry had failed her yet again. "I'm sorry, dad." Tears began to fill her eyes. "I know you wanted a witch, but instead I turned out to be a muggle. I know you wanted me to be a strong person, but I am so weak. And I know you wanted a girl that made good decisions, and then I go and do this."
"Oh child," he muttered. He walked up to her and wrapped his arms around her. She wept softly into his shoulder.
"I'm so sorry," she said softly. He shushed her and stroked her hair comfortingly.
"There's nothing to be sorry about, Sarah." he whispered. "You're my daughter and you mean the world to me. I'm sorry it took so long for me to see it. I wouldn't have anyone else for a daughter. I love you, Sarah."
"I love you dad," she sobbed. He hugged her closer until she stopped crying. He looked her in the eye.
"I don't know how long it'll take, but I promise that you won't have to go through this alone. And Bud will be dealt with. It won't be easy, and it won't be fun, but he will be dealt with." She nodded and wiped the tears away.
"Thanks," she whispered. She turned and began to walk away, accidentally bumping into the edge of a table. Snape snickered a little and she scooted to the side, rubbing the spot she had hit. "Careful," he muttered.
"Ah, shuddap," she chuckled, and went back to the Gryffandor tower.
