A.N. So sorry it took so long for me to post again, but my parents dragged me off on holiday, where I got burnt. Horribly. Then, when we got back my mother deleted the next three chapters of this story and a fluffy one-shot I had done, so I had to begin again from scratch. Here's the next chapter anyway. Enjoy. I'll just go and bathe my burnt back. Ow.

Disclaimer: It's my birthday coming up; perhaps I'll be given the Harry Potter universe as a present. Until then, don't own it.

Can't get the line to work. Imagine this is one.

The next morning, Hermione woke, as usual, before any of the others, so she was able to untangle herself from a grumbling Ron's arms. 'Too early, 'Mione' he muttered, still half-asleep. 'Come back to bed' she blushed brightly at his sleepily innocent words, struggling gently as he tried to wrap his slender arms back around his unusual teddy bear.

'Stop it, Ron!' she giggled, pushing him off her. He groaned, and rose up from the bed. 'We'd better get dressed before the lads wake up' he told her, and she nodded ferverently. Ron looked shifty. 'Uh, 'Mione?' he asked her. 'Yes, Ron?' she replied, dragging on a pair of shorts and t-shirt from his trunk, as it was quite warm.

'I don't have any clothes. They're all in your trunk'. Hermione sighed. Honestly, he was stupid sometimes. Why didn't he think to bring some with him last night? 'Well then, you're just going to have to wear some of your own, and hope they fit my body ok' She told him, and he obediently went over to his trunk to find something.

After finding a t-shirt that could be a half-decent dress, he pulled his nightdress over his head, eyes firmly shut. Hermione yelped. 'What do you think you're doing?' she hissed. 'Get into the bathroom! The boys could wake up and see you any moment. I've done enough obliviating for the next year'

Ron glanced around and shuffled, being pushed firmly by Hermione, into the bathroom. He shifted awkwardly under her gaze. 'Aren't you going to leave?' he asked. 'No' she glared. 'Get dressed' He clamped his eyes shut. Ron was no creep; he wouldn't have looked even if Hermione wasn't there, despite REALLY wanting to, but he liked to be trusted.

'Today can't have any of the glitches of yesterday, ok?' she told him 'We don't want to have to obliviate our best friend again, or march into the Slytherin dungeons. I am going to teach you to act exactly like me, and you will learn. You in turn will tell me how to act like you, and I'll do as you say. We can't get caught again; the risks are too high. We're just lucky the holidays start on Tuesday. That means we only have to put up with one day of lessons'

(A.N. They switched on Saturday morning, having had the potion spilt on them on Friday. The Lavender and Malfoy incident happened on Saturday, and Hermione slept in the boys' dorm Saturday night. It is now Sunday, and the last day of lessons is Monday. They leave for the Burrow on Tuesday)

She sensed Ron was about to speak, but she shushed him. 'Yes, I know you'll have to go home to your family over Christmas, but we'll cross that bridge when we come to it. Good thing you already invited me before we switched' she smiled rather shyly, and he blushed.

'So when will you begin to teach me?' he asked, very aware of the fact he was exhausted. 'After breakfast' she told him, and he smiled at her. How well she knew him. The pair left the bathroom, but as it was still early, the other boys were still happily snoozing.

'Can I go back to sleep, 'Mione? Please?' he pleaded 'Just for a few minutes?' She rolled her eyes and wandered off to brush her teeth, wondering whether Ron would mind if he found out she had used his toothbrush. It was, after all, his mouth.

Ron took this as the green light, and settled down blissfully to get a few precious minutes shut eye, content knowing that the other boys wouldn't be up for ages, and Hermione would be there to help him get through this whole ordeal. With this in mind, he drifted off.

He awoke to raucous laughter. Seamus and Dean were nudging each other. Hermione came out of the bathroom, and realised how it must look. 'Hermione' was in 'Ron's' t-shirt, not the nightdress 'she' had been wearing the night before; none of them had seen her change. 'Hermione' was asleep in 'Ron's' bed, and he was coming out of the bathroom looking shifty.

'What were you guys doing?' grinned Seamus. Hermione punched him. Ron smiled at her. She was getting better at this hitting lark. 'I slept on the floor, you cheeky sod!' she told him angrily. Dean smirked, as Seamus went off to the bathroom to bathe his eye. 'Then why's she wearing your t-shirt?'

Hermione gaped, for once in her life utterly speechless. Ron leapt to her aid. 'It's not Ron's. It's Harry's.' A gasp resounded in the room. It was true; Ron had nicked it from Harry about a week ago, and forgotten to give it back.

They gaped, open mouthed, as the Chosen One yawned, slid out of bed, smiled at 'Hermione' and padded into the bathroom. His hair was even more messy than usual, he wasn't wearing a pyjama top, and his bottoms were on back to front.

Dean clapped 'Ron' on the shoulder consolingly. 'Jeese, I'm sorry, mate. We never knew'. 'Ron' simply stared. She was not supposed to have THIS happen to her. It was bad enough when they thought she had slept with Malfoy, but Harry…?

Ron was shaking a little. The boys presumed she was embarrassed at being caught out, and afraid they might turn her in, but he was, stupid though he knew, jealous. Why did Harry grin at Hermione like that? WAS there something going on between them? Something he hadn't picked up on?

He mentally shook himself. Harry was his best mate; he'd ask permission before starting anything with anyone so close to him. And he wouldn't do it anyway; he knew how Ron felt about Hermione. He was utterly paranoid; Hermione had slept in his arms last night, and she woke up in them.

He shivered. Down boy. Oh, wait…No need for that anymore, at least until Hermione prepares the potion.

Harry came out of the bathroom again, this time with his hair brushed so it was merely messy, not gale-swept, and much more awake. He still had no top on though. Ron felt like ripping his…throat out (A.N. Sorry to disappoint! ;). He was invading his territory.

Stealing his Herm…no! What kind of a thought was that!

The other lads were entirely oblivious to this whole drama in Ron's head. Seamus was disappointed; Dean was amazed, and Neville was simply confused. Harry wandered vaguely over to his two best friends, and plopped down on the bed in between them. Ron glared, Hermione sighed.

Neville piped up nervously, raising his hand as if he was in class. 'Yes, Neville?' asked Seamus 'Well, it's just, uh, Ron's bed's been slept in. If she slept with Harry (Harry's eyes shot open in surprise) and Ron slept on the floor, who slept in his bed?'

The three lads (minus Harry) stared speculatively at Ron and Hermione, as they answered simultaneously 'I did'. The boys grinned.

Ron and Hermione looked at each other. Ron quickly reached a decision. He snuggled up to Hermione and snaked his arm around his body's waist. 'Fine, we slept in the same bed, but nothing happened! Ron was the perfect gentleman. I'm wearing Harry's shirt because I didn't bring any clothes with me last night, and I can't go down from the boys' dorms in my nightdress, that's all'

Hermione looked furious. It was true, but they didn't have to know that! She had been preparing herself for another round of obliviating, and felt she was getting rather good at it. But she still objected to Seamus and Dean slapping her on the back roughly, winking at her and sniggering.

Even HER Good Girl reputation wouldn't withstand this.

Still can't get the line to work. Imagine this is one, too.

A.N. I think I've given away rather a lot of the plot for the future in this chapter. Don't worry though, my loyal reviewers and those scumbags who read but don't review, there's a couple of twists up my sleeve I don't think any of you know about yet. Mwahahahaha!

A.N.2: You may have noticed that when Ron and Hermione are speaking, Lavender is in italics. This is because they don't like her, and sort of roll their eyes or groan when they say her name. It's just normal type Lavender when it's her speaking, or when it's someone who she's friends with speaking about her. Oh, and it's Lavender in the A.N.s too, but I don't like her either.
