A 'pop' disturbed the surroundings of Spinner's Lane. A woman who appeared out of thin air, carried a bundle in her arms. A hood was pulled over the woman's fiery red hair, the shadow of the hood covering her bright green eyes. The bundle in her arms was a mistake.

A mistake brought about by Severus Snape.

The girl was newly born, even her husband didn't know about her. The woman had concealed her pregnancy from him by glamour charms and spells. Now that the child was out, she was going to give her to her father.

Again, we are brought about to Severus Snape.

The bundle in her arms cooed quietly and Lily Evans smiled down at her child. Well, it wasn't her's anymore. She had told her old friend Severus that she was pregnant with his child, and he resolved the issue, saying he would take care of her. Her husband would never be none the wiser.

Lily drew in a breath and knocked on the door to the Snape house.

It was a quiet night for Severus Snape as he read his book in his old armchair. A cup of tea was held in his hand. The lamp that hung from the ceiling was filled with candles - only of which half were filled - gave Severus enough light to read his ancient leather tomb.

Hearing a knock at the door, Severus sat down his cup of tea and marked his page in his book and carefully sat it on the small rickety table beside his old armchair. He stood up and swept his way to the door. He had been anticipating this night sine Lily Potter told him of her pregnancy with his child nine long months ago.

It had all happened by accident. No, it wasn't a night of drunken passion between two lost lovers, but a potions accident that caused Snape - whenever he touched a woman(whether it be on the hand, shoulder, or elsewhere) - to become impregnated with his child. The night of the accident was also the night that he had apologized to Lily, and thanked her when she accepted his apology with a hug. He later realized his mistake a week later and told her. She was shocked, but soon got over it and said that she would have his child. He made up for it by saying that he would raise the child.

Severus opened the door to see Lily there, holding a bundle in her arms. He smiled at her and welcomed her into his house. The red head smiled back but shook her head.

"I should be getting back to James,"she said. "Here. Here is your daughter. Raise her well."Severus nodded and took the bundle.

"Of course Lily. I will give her the love of two parents,"Lily smiled and Apparated off his doorstep. Severus sighed and shut the door.

The bundle in his arms cooed softly and he smiled down at it. A tuft of black hair rose up from it's head and her eyes were already darkening from the newborn baby blue to a dark black. Good, no one would be able to tell that the child was Lily Potter nee Evans'. Severus took the wand out of his pocket and waved it around the room.

The lamp filled with candles was bright enough to light the whole room now. The rickety table was more sturdy and the old, threadbare green sofa was white and brand new looking. His armchair looked new as well, and was a leather brown. He sat down in the chair, the bundle still held delicately in his arms.

"Hello little one,"he said softly. "I'm your daddy, Severus. What's your name?"He knew the child wouldn't answer him back, but a piece of parchment showed from within the bundle. He carefully pulled it out and looked at it.

It was a birth certificate. There was also a note from Lily. 'Name her Severus, whatever you want. Send a copy of her birth certificate to the Ministry. Thank Merlin they don't require the parents names - Lily' Snape sighed to himself and looked at his child. According to Lily, it was a she.

What female names did he know? Severus let out a small smile as he recalled one that he would name her.

"Addriene Lillith Snape. That's her name,"he said softly. The little girl cooed and he let out a small chuckle. "Like your name, do you? I do too. It's fitting." Severus sat with his daughter until the early hours of the morning. With Addriene asleep, he stood up and moved a book from the bookshelves that surrounded the room. One bookshelf fell away and a doorway appeared. He opened the door quietly to not disturb his daughter and walked into the room.

With a wave of his wand, the room was filled with light. The space was a sweet yellow colour, he didn't know what the gender of his child would be so he chose a gender neutral colour. A border of teddy bears was around the top of the wall and a white crib awaited his daughter's sleeping form. He walked over to it and sat her down gently. He covered her small form with a white blanket and he charmed the blanket a sweet, girly pink colour. He brought the rocking chair from the corner of the room over to himself and he sat in it, watching his daughter in peace.

And that, is how Snape's daughter came to be.
