Title: One Night Stand

Rating: T

Summary: It was a one night stand he didn't remember, at least not until now. And now he has a decision to make: pretend like nothing happened; or take responsibility for what did happen. SS/OC AU

A/N: This does contain teacher/student, but only in the beginning. Also, I am not saying with this story that I condone what they did. I am saying I believe in taking responsibility for your actions.
This is an AU in a world where Voldemot was somehow destroyed at the end of OOtP and Sirius lived. So no more voldy! So, I guess this is at the end of Harry's fifth year? Enjoy!

It was a one night stand, and he did not remember it. At least, not until the night came when there was a knock on his office door. Severus grumbled to himself as he slowly stood from his seat and walked around his desk to the door.

Who on earth could be coming to his office at this hour, it was almost curfew. Besides, there was only a week and a half left to the year. He was almost done grading the final assignments and then he was done.

Severus opened the door and saw seventh year, Jennifer Puddle standing in his doorway. Now he was very confused, what could she possibly need from him? The seventh years had finished their NEWTS and had no school work left. And as far as he could remember, Jennifer was not pursuing a career in potions.

"Yes, Ms. Puddle?" he asked, showing every ounce of his irritation.

Jennifer stared at her feet. Allowing her shoulder-length brown hair to shadow her face. She swallowed hard, then looked at her professor. "I need to talk to you about something. In private." she added.

Severus considered shutting the door in her face. Why should he have to waste his time talking to a student about her personal problems? But there was something in her dark brown eyes that was different. She looked scared.

Severus opened the door a little wider and stepped aside to allow the girl to enter.

"May I sit down?" she nodded. Then took his own seat across from her. "What is this about, Ms. Puddle?" he asked finally when she did not speak.

She looked up but avoided meeting his eyes. "I have a problem, a big problem really." She paused and looked at her professor for a moment. "The problem sort of has to do with you," she admitted, "That's why I'm here."

Severus stared at her, his face blank with confusion. What could he have done that would have affected this girl? His thoughts traveled to his death eater days, then to his spy days, and then to the recent destruction of the dark lord.

"I'm pregnant."

Severus was woken out of his thoughts by her statement. She was… pregnant? What did that have to do with him?

"And why should that concern me?" he asked calmly.

Jennifer stared at her hands, which were in her lap. "Y-you're the, the father." she stuttered out.

"That is impossible." Severus told her, his voice sounding more agitated. "I have never slept with one of my students." Especially not with a Hufflepuff. he added mentally.

"It was an accident. Just over a month ago, during a Hogsmeade trip. I guess we both got drunk, and- well, I woke up in bed with you." she told him gravely. "You were still asleep, so I just left. I-I was too embarrassed. I knew you probably wouldn't remember." she paused then added quietly, "I hoped you wouldn't remember."

Severus's head was spinning, he could not process what this girl was saying.

"I wouldn't even have bothered to ever tell you, but I just found out that I'm pregnant."

Severus felt sick. This was impossible, but he remembered the night. He had been depressed, and had had a few too many drinks; and that was the last thing he remembered before waking up the next day with a hangover. "Have you told anyone?" he asked, and now he was the one who could not meet her eyes.

"I wrote to my parents the a few days ago." she answered. "But don't worry, I didn't tell them it was a teacher's or anything. I just told them I made a mistake and got pregnant."

"And what did they say?" he questioned, when she didn't volunteer the information.

She swallowed, trying to hold back tears. "They told me I was on my own. They told me not to bother coming home. I've been kicked out."

A bitter taste filled Severus's mouth. What kind of parents would tell their child that? Then he felt sick again, as he realized this was really all his fault. If he hadn't gotten drunk, she wouldn't have wound up in bed with him.

"What are you going to do?" he asked, then thought of how that sounded. "I meant, have you figured anything out?"

Jennifer smiled slightly. "That's actually why I'm here. I was hoping, um, I know it's a lot to ask, but" she closed her eyes because she couldn't bare to look at him when she asked, "I was hoping I could stay with you until I get things sorted." she finished quickly.

And how could he say no? A seventeen year old girl, thrown out into the street without a place to stay, or money, or a job, and a baby on the way. His baby…

"You can stay with me." he told her.

Jennifer smiled as tears flooded her eyes. She had been so scared he would say no.

"You will stay at Hogwarts when all the other students leave. I have to remain here a day longer, since I am on staff. Then we can leave together."

Jennifer stood, nodding her head. Grateful that she had somewhere to go. Severus stood and led her to the door.

"If you need anything else," he began, "You can come by and let me know."

Suddenly, Jennifer threw her arms around Severus's middle. Hugging him tightly. "Thank you so much."

Severus waited until she released him, and walked out of his office, before allowing a small smiled to form on his lips.
