I'm sure Potions aren't meant to do that...

Summary – What happens when Draco and Harry are involved in a Potions accident, and end up with a baby to look after? Who is this baby and where did it come from? And more importantly, what are they going to do with it now they've got it?

Disclaimer – Harry Potter isn't mine! If it was, it wouldn't have ended up how it did, and Draco and Harry would have got together.

This is my second fan fiction, and it's a prequel to my first, as requested.

Dedications – This chapter is dedicated to njferrell, who asked me to write the prequel. I hope this is ok for you.

Harry's thoughts

Draco's thoughts

"Parseltongue"

And on with the story!

"Harry! We're going to be late! And you know that Professor Snape hates Gryffindors. Why give him a reason to hate us even more. Or worse...dock points from us!" Hermione called from the portrait, Ron swinging the door next to her, ignoring the protests from the woman in the painting. "C'mon Harry! She'll start yelling in a minute." He called, moving hurriedly backwards to avoid a whack on the head from his best-friend. Harry smirked at their behaviour, pulling himself up from the comfy armchair he was slumped in, and picking up his bag that was placed in the way of everyone who crossed the common-room. "Ok. I'm coming." He laughed at his two friend's expressions; one of complete relief, the other of humour.

They arrived a few minutes before the lesson started, and Harry leant against on of the walls. "See Mi. I could have stayed in the chair longer." He grumbled, looking at his feet as Hermione frowned at him. "Harry. At least he can't tell us off for being late."

"Of course he can." A cold voice sneered at them, and Harry looked up as non-other than Draco Malfoy stepped round the corner, with a group of Slytherins. Harry blushed slightly as he saw the handsome blonde, his tie partially done up and the top few buttons of his shirt undone, exposing the creamy skin below. Skin that just needed to be kissed, licked...Wait! Harry, you have to stop thinking about Malfoy in this way. "You're Gryffindors." Dra-Malfoy said as if that explained all, before slouching against the opposite wall, his shirt ruffling and showing more of that delicate skin. Harry shook his head and looked away, his cheeks flushed.

"Aww. Is the little Gryffindor thinking bad thoughts about a Slytherin?" Malfoy leered, and Harry flushed a little more. "You wish Malfoy!" He said heatedly, but the blonde merely smirked and licked his lips before turning to Blaise. The brunette slumped against the wall, running a hand through his naturally messy hair.

"All of you in!" Snape called as he swept through the corridor from the dungeons, where, Harry guessed, his private rooms were. As they filed into the classroom, Hermione and Ron sat together at the front, and Harry looked for a partner who wasn't Slytherin. "Mr Potter. Stop standing there like a dummy. Just sit down with Mr Malfoy and get on with the work." Harry started at Snape's voice.

"Professor. You can't expect Harry to work with Malfoy!" Ron burst out, standing up, red in the face. Snape just sneered at him. "Mr Weasley. I expect him to do just that. Now sit down before you get points taken off Gryffindor." Hermione looked scandalised, and pulled Ron down into his seat before the red-head could say any more. Harry shrugged at her apologetic glance, and slumped into the seat next to Malfoy, who was smirking at him, along with most of the other Slytherins. Of course they would be. It's their Slytherin Prince working with the Boy-Who-Lived. What a headline. He thought dryly.

Snape tapped on the board, and words appeared, written in his own neat, cursive hand. "Well then Potter. You get the ingredients, and I'll get the fire started." Malfoy said, not bothering to look at Harry before turning away to light the fire underneath the small cauldron beside their shared desk. The brunette shrugged and walked slowly over to the ingredients cabinet, quickly gathering the bottles. "Hey. I'm sorry mate. Bad luck." Ron said from beside him, and Harry grinned. "It's fine Ron. It's not like it could have been helped." He shrugged and walked back to the desk, putting the bottles down on the table.

"Careful Potter!" Malfoy exclaimed as he almost dropped one, and he started at the sudden noise. "Damn Malfoy. Don't scare me like that!" Harry shouted.

"Ten points from Gryffindor for shouting in a classroom." Snape said as he swept round the room, looking into steaming cauldrons, and peering over people's shoulders. Harry grimaced, and bit his cheek as he tried not to answer back.

Harry watched Malfoy carefully measure, cut and place ingredients into bowls, impressed at the blonde's concentration when doing something he enjoyed. He found himself wondering if Malfoy would be this attentive to details in bed, before mentally slapping himself for having such a thought. When he was finished, Malfoy looked up and scowled. "What are you doing Potter? Not helping, that's for sure." Harry flushed and retorted. "If you would let me do something, I would." Malfoy backed away from the desk. "Go on then Potter. Your turn."

The brunette bit his lip in concentration, carefully placing in the ash winder eyes with a bat's leg, and stirred clockwise...once...twice...thrice, then he stopped. He could feel the stare from those grey eyes on his back, and he looked at the board, determined not to make any mistakes. He picked up the dried lacewing flies and scattered five into the bubbling pot, waiting for half a minute before throwing in the other four. Harry looked up to see Malfoy watching him, and set an alarm for five minutes, when the next ingredients were to be added.

Hearing a splash, both Harry and Malfoy looked into the cauldron, wondering what on earth had happened, as neither of them did anything. Looking up, Malfoy noticed Pansy and her partner staring at them with smirks on their face. So, they were the ones that did that. I wonder what they put in it. Draco thought. Harry grabbed his arm and he was twisting round to yell at the Gryffindor, when he noticed the purple fumes that were being given off from their potion.

He was beginning to back away, as was Potter, when the whole cauldron exploded and covered them both in purple gunk. They both spluttered and staggered back, falling onto the floor. Hermione and Ron rushed forward before being ordered back by Snape. "Mr Malfoy. Mr Potter. What happened to your potion?" He asked, a little worried. That didn't help Harry at all, who could feel things moving inside his body.

"Sev. I feel weird." Malfoy whispered, and Harry nodded in agreement. "Get out of those robes." Snape snapped, and they struggled to take off their own robes. Malfoy stood up shivering in his trousers, but Harry lay on the floor, his eyes fixed on his stomach, which was rounded and definitely bumped.

"What the hell?! I'm pregnant!"
