Here is chapter two.
"Back to work, Ms. Granger." he ordered, looking up at her. She looked away and started working again. Suddenly, the door opened and her two best friends ran in.
"You're fifteen minutes late," the professor muttered, still grading papers, "that earns you another detention." They both groaned and Ron muttered something about a 'greasy git'.
"That's another detention, Mr.Weasley." Prof. Snape snapped. They were both silent. The professor stood up and stacked the papers neatly on his desk.
"You will help Ms. Granger and then you are to clean under every desk." he ordered, gesturing toward Hermione. They groaned and slumped over to her.
"Where were you two?" she whispered, looking at them.
"Malfoy." Harry replied.
"Quite." Snape ordered in his low, icy tone. He sat back down and took out a book. They kept quiet as they worked.
"Who's the girl?" Ron asked, after awhile.
"I think she's his daughter." Hermione answered, not stopping.The classroom door opened again; his wife walked in, carrying a crying baby. He was dressed in dark blue footy pajamas. He had a headful of black hair and his face was red form crying.
"He's teething." she explained, handing the baby to the professor.
"I took care of Aribella when she was teething." he muttered, holding him and patting him on the back.
"I have to take a bath, remember." she said, smiling as she walked out of the room. He rocked the baby and made shushing noises.
"Ari, go get that sleeping drought in my office." he ordered, closing the door and walking to his desk again.
"That baby needs to shut up." Ron muttered, as they covered their ears. Aribella came out of his office, carrying a veil and a bottle of juice.
"Thank you, Ari." he said, taking it. He poured a little bit of the veil into the bottle and it shook it up.
"Come on, Julius. This will help." he calmed, laying the still crying baby back in the nook of his arms. He put the bottle in his mouth and the baby started drinking. The professor leaned back in his chair; rocking the child slowly.
