A/N: My sort-of muse (who gives me an idea for a story and then deserts me to finish it) gave me this idea, and I just had to get it down! Anyway, this is going to be a fairly short fic, not like the Witches Watcher (or as I've so fondly named it, the bane of my existence), probably about 5 chappies.

Disclaimer: It's mine! All mine, dammit! OK; I own nothing. Happy now?

SLEEPING WITH THE ENEMY- CHAPTER 3: THE TRUTH

"… it's about you getting even with him. This is about revenge, sweetheart, and it always has been." He said before capturing her mouth in a second kiss.

Dawn responded to the kiss. Draco moved down to her neck and started sucking gently, all the time nudging her gently over to the bed. "I don't think this is a good idea." Draco didn't stop and Dawn didn't make him. He pulled the strap of her top down and slid his hand under her top. "Draco, I really don't think this is-" Dawn said pushing him away softly; looking over his shoulder. She suddenly pushed him away hard. "Harry, wait. It's not what it looks like!"

Emotions placed across Harry's face. Disbelief, anger, hurt. Mostly hurt as he watched his girlfriend and his rival kiss passionately. He blinked his eyes a couple of times to try and persuade himself that it wasn't real, this wasn't happening. But it was.

Harry couldn't draw his eyes away. All he could do was stand there in some perverse way and watch as Draco slowly moved her towards their bed, kissing her neck and shoulder.

He had heard what Draco said before he realised what was going on. Getting even with him for what? Revenge? He hadn't done anything! He saw him kiss her. He heard her weak protests. He saw her push him away gently, but he went back to her. His eyes met hers as she looked up and then pushed Draco totally away. Too little, too late.

"Harry, wait. It's not what it looks like."

Then what the hell is it? It looks like his girlfriend was making out with his enemy, but apparently that was wrong. Yeah right.

"I think it is what it looks like… I just came to tell you that Tonks said she'd go in my place; I'm not going anywhere… I guess I'll leave you to it." Harry backed out of the room, closing the door behind him. He leant against it to gather himself together before walking away, as far away as he could get without actually leaving the protection of 12 Grimmuld Place.

Draco was slightly shocked at Potter's reaction. No screaming, no tears, no fighting. He shrugged and turned back to Dawn. "Now, where were we?"

"You're unbelievable! Harry's a great guy and I just hurt his feelings. I can't believe I let you ruin things. I'm going after him." She grabbed her jacket and headed towards the door.

"Dawn!" Draco called annoyed. "He doesn't want to talk to you right now."

"Maybe not, but I'm gonna try. I want you gone by the time I get back." She said stubbornly and coldly.

Dawn caught up with Harry outside. He was sitting on the rubbish bin just looking into space. She sat down next to him.

"Harry, I'm so sorry."

"Go away." His voice was hollow and gruff.

"Please, just let me explain." Dawn took his silence as a yes and continued. "After patrolling I went to our room and I thought you'd gone. I was upset and angry 'cause I thought you'd left me again."

"So this is all my fault? You were trying to get back at me!" Harry said defensively.

"No, it's my fault. I'm just telling you what I felt. I wasn't trying to get back at you; I just wanted to be close to someone and you weren't there. Draco came in and started staying stuff. He said he cared for me-"

"I care for you." Harry insisted softly.

"-he said that it was just a bit of fun. One thing led to another and you saw what happened." Dawn finished quietly.

"Are you finished?" Dawn nodded. "Good. I already know all that, well, kind of. There are some things that I don't know; I want you to tell me, honestly. Was that the first time?"

"Harry-" Dawn pleaded

"Was it the first time?" He demanded.

"No." Dawn admitted quietly.

"When?"

"I don't see what this is going to-"

"When, Dawn?" His voice was hard and unfeeling.

"Last night when you were away. Harry I didn't mean to-"

"You didn't mean to? What, did you accidentally fall onto his lips? ...Have you slept with him?" She didn't reply. "Oh Merlin. Was it in our bed? It was, wasn't it! Why? I thought you loved me." He finished dejectedly.

"I do. I'm so sorry." Tears started trickling down Dawn's cheeks.

"Yeah, you said. How long has this been going on? Weeks? Months? Have you been seeing him behind my back since we got together?" The hurt was replaced by anger.

"No, of course not! It was just the once."

"And tonight. If I hadn't got back, you would have done it again."

"You were there! You heard me tell him to stop!"

"You didn't try very hard to make him, did you? How am I supposed to believe you? You lied to me. You cheated on me…with Malfoy. I thought I knew you." He got up and went back inside.

"Harry, I love you." Dawn sobbed.

"Yeah? Well, you've got a funny way of showing it." He said scornfully, turning his back on her and going inside.

The next morning, Dawn woke up alone, tired and feeling very sick. She dashed to the bathroom, and that is where Ginny found her half an hour later.

"I spoke to Harry." Ginny said, sitting down on the edge of the bath tub. "He found out, huh. He was bound to sooner or later."

Dawn didn't say anything. Partly because she had nothing to say and partly because she felt another wave of nausea coming on and spilled the contents of her stomach down the toilet.

"Are you alright?" Ginny asked, concerned. "Is it Harry?"

"I can't believe I was so stupid!" Dawn wailed. "He saw me and Draco kissing. I was going to stop him, I was just lonely."

"Dawn, don't even think about blaming this on Harry." Ginny warned.

"I'm not." Dawn sighed. "It's 100% my fault; 99% my fault…well it is fault a little!"

Ginny rolled her eyes. "Are you coming to breakfast?"

"Gotta face everyone sometime. Besides I feel much better now." She stood up. "Or maybe not…no, I'm fine. I'm fine…I think." Dawn wobbled unsteadily down to breakfast. All eyes turned to her as she sat down. Except for Harry's.

Willow looked disappointed, Spike looked angry, Mrs Weasly looked absolutely livid and Buffy looked pityingly at her. She sat down next to Ginny and looked at her breakfast. After her sickness that morning, she really wasn't hungry. Buffy passed her a steaming cup of hot coffee. But the smell made her nauseous again and she dashed from the room.

"What was all that about?" Buffy asked

"Dawn's not feeling so good." Ginny explained. "She was sick this morning."

However much he tried, Harry couldn't stop the concern that built up inside of him.

"Well, if it isn't Potter all alone." Draco taunted.

"Get lost, Malfoy." Harry growled.

"Where's your girlfriend scarhead? Found someone better has she?" The ex-Slytherin smirked.

Harry clenched his fists by his side. 'He just wants to wind you up. Don't let him do it.' He told himself. "Shut up, ferret-face."

"Mind you, I'm not gonna complain. She's a firecracker, but then you probably know that…or do you? Maybe the reason she was so keen to get it on with me, was because you weren't giving her any. You're not a eunuch are you?" Draco eyed Harry up and down warily.

Harry's face had gone crimson as he fought to keep himself under control.

"Ah well, your loss is another's gain. Your little slut- wait, she's my little slut now isn't she? Anyway, 'Dawnie' is-"

Suddenly, Draco found himself soaring across the room.

"I'd advise you not to talk about my sister like that Mister Malfoy." Buffy said in a voice of steel, her eyes flashing and Draco found out what it was like to get on the wrong side of a slayer.

"Are you alright Harry?" the slayer asked.

"I'm fine." He ground out.

"You know Dawn loves you, don't you. She regretted him by the next morning; this thing between the two of you is tearing her apart and, believe me, that never ends well for anyone. Anyway, don't let him get to you. See ya!" and with that the whirlwind slayer rushed out of the room, leaving Harry standing open mouthed and Draco picking himself off the floor.

Dawn ventured down into the lounge nervously. She wasn't in the mood for seeing Harry right now. Mrs Weasly was the only one there, so Dawn sat down and started to read the daily prophet. One of the headlines jumped out of her:

Harry Potter Betrayed by Love reported by Rita Skeeter

You would think that with all the hardships the-boy-who-lived has faced since the tragic death of his parents; he had deserved some luck in his love life. But no; Harry was cruelly cheated on by his girlfriend, an American muggle born.

It is rumoured that Dawn Summers has had a string of affairs over their two year relationship, one man, Angus Bellbottom, describes his meeting with her. "Miss Summers did not mention that she was in a relationship, [he says] if she did I, of course, would not have got involved. I was taken in by her…just like Harry Potter!"

Muggle borns are notorious for their muggle ways, and if this is one of them we can only warn Harry Potter, and the rest of the wizarding world, to steer well clear.

"Oh my God." Dawn whispered to herself upon reading the article.

"Is that the 'Daily Prophet'? Don't worry, they print all kinds of trash. Most people know it's a load of rubbish." Mrs Weasly said, not looking up for her knitting. She didn't speak with her usual warmth, but Dawn was surprised that she was talking to her at all. Mrs Weasly was known for being very protective of her family, and to her Harry was family.

"If you want my advice," she said, "then you'll take no notice of that nonsense and talk to Harry."

"Why? Why do you want me to talk to him?" Dawn asked.

Mrs Weasly looked at her as if she was crazy. "Because you make him happy." She explained slowly and patronisingly. Dawn looked surprised and Mrs Wesley rolled her eyes: "Americans!"

Dawn and Harry were avoiding each other. Dawn spent most of the day in their room, thinking about what Mrs Weasly had told her, and Harry spent it in Ron's thinking about what Buffy had said.

Ginny tried to talk to Harry, but he was still mad and hurt. Although; he was starting to believe that Dawn had spoken the truth; that it had been a one off. After all, he did hear Dawn pushing Draco away and she came after him instead of staying with the ferret.

Harry had let his anger get the better of him and given Draco a black eye. He had been a lot nicer to be around after that, and Draco had the smirk wiped off his face once and for all and was also more bearable.

Ginny took Dawn's dinner up to her room as she still wasn't feeling right. She also collected some of Harry's belongings from the room he shared with Dawn and moved them into Ron's room (he was still away).

A couple of days later, things returned to normal; more or less. Dawn and Harry were still avoiding each other, despite all the efforts to get them to talk, and Dawn was avoiding Draco like the plague, but apart from that…

A few days after Harry found out, Dawn was still being sick in the mornings. Buffy asked Willow to check on her sister. Just to make sure that it was just her being very upset about Harry making her sick as everyone thought, and not something serious.

"OK, Dawnie, just lie back and I'll see what's wrong." Willow said chirpily; it annoyed Dawn to no end; how can anyone by that happy this early in the morning? OK, so it was 11am, but still...

Willow placed her hands over Dawn's belly and a golden glow emitted from them. She moved them slowly over her stomach, muttering to herself.

"Right, all looks normal, let me just look over here…Oh Goddess." Willow pulled back, ash white.

"What's wrong?" Dawn asked, worried.

"Dawnie; I don't really know how to say this…you're pregnant."

Dawn's face also went white as a sheet and she felt an entirely different kind of sickness. "Pregnant?"

Uh-oh! Who's the daddy? Is it Draco or Harry or someone else?

Now this is the part where I beg for reviews so here we go; please review, blah, blah, blah, please review. Got it? Great!
