A/N: Merry Christmas! I saw the prompt below on Instagram and immediately thought of this. I'm going to post this in three parts, all on the same night if the site will cooperate. Hope you like it. I don't own Harry Potter. Reviews make my day so I'd love feedback!

Prompt: Your kid calls you to their room one night, 'there's something under the bed'. You go down to check it out and upon inspection see your child under the bed and they whisper 'I think there's a monster on the bed.'

In hindsight, Molly Weasley thought that it could have been worse. It could definitely have been worse. All was well that ended well anyway. Although, equally in hindsight, perhaps encouraging Fred and George to make friends with the nice, calm, studious boy from the village wasn't the best idea. In hindsight, she really should have been suspicious when they stopped complaining so soon about having to spend time with Jeremy. In hindsight, she should have been really, really, really suspicious when they suddenly asked if they could have a sleepover with him. But then again, all was well that ended well, and this at least, could have been worse.

It all started several months ago really, when the new muggle family moved into the village and Molly met the father while shopping. He had his son with him, Jeremy, at seven was a year older than the twins but a year younger than Percy. She'd gotten talking with his dad, who was named Marcus, and they got to talking about their kids, and he mentioned that Jeremy was rather quiet and found it hard to make friends, and that he really wished that he would spend less time reading and more time running around. In return, Molly shared a few stories about Percy, and how her children frequently dragged him out to play. And they kept talking, and slowly, the plan was born.

It wasn't a very sophisticated plan, it merely involved getting the twins and Jeremy together and hoping that they would be a good influence on each other. Molly was sure that the twins were old enough to remember when they couldn't mention magic, and she thought Jeremy might calm them down a little. Marcus in return hoped that the twins, highly active children from what Molly had said, would encourage Jeremy to spend a little less time reading and some more running around and making friends. In hindsight, the plan may have been a little optimistic.

It would probably have been alright if Percy hadn't been away at the time. If both Percy and Jeremy had been around, then maybe they would have managed to reign in the twins. As it was, it was two against one and Jeremy didn't have a hope. It wasn't that it was an instant change, it was merely that it was a steady one. In hindsight, maybe she should have supervised her sons more during the visits.

The first play-date had to be by necessity, in the village. Marcus and Sharon (his wife) were still painting (Molly did not want her sons anywhere near tempting cans of paint and paintbrushes. That was not a disaster waiting to happen, that was a disaster dancing around in a clown costume and begging to happen.) their new house, and Molly quickly made up an excuse that they were renovating theirs and there were a lot of tools lying around (Bringing a muggle boy into the Burrow was also a disaster begging to happen). So, the first play-date happened in the village park.

It was summer, about a month after the muggles had moved in when Molly finally convinced the twins to meet up with 'the nice muggle boy' and Marcus convinced his son to emerge from a good book for an afternoon. Marcus brought Jeremy to the park, and Molly brought the twins. They introduced the boys and then got into a conversation. In hindsight, supervising the children may have been more important. Or at least, supervising Fred and George.

As first impressions went, the three children did not hit it off. Fred and George took one look at the boy and thought 'Percy will like him' and Jeremy took one look at Fred and George, dressed in a motley assortment of Percy and Charlie's old clothes, much patched and already with a couple of tears in them, and promptly suggested they play hide and seek.

This was not out of any wish to actually play the game, but merely because Jeremy happened to be very good at hiding, and he had his book stuffed up the back of his jumper. Unfortunately for him, Fred and George had six years experience playing hide and seek in the burrow, which offered far more, and better, hiding places, and found him within two minutes, with 'Treasure Island' barely opened.

Also unfortunately, Fred spotted the cover of the book and suggested they go treasure hunting. Jeremy said the book wasn't about treasure (he'd only just started it) and George asked what it was about.

"Pirates"

"Lets play pirates then!"

"We can make swords out of sticks!"

"And eye-patches from leaves!"

This did actually sound rather fun. Jeremy hesitated, looking from his book to the two boys.

"We would need a ship" he said cautiously

"We can use the castle!"

"Yeah, the top of the slide can be the lookout."

"And it's already got rigging."

The play castle did indeed have rope netting to climb up. That did it. Jeremy carefully gave his book to his dad, who was by now too distracted to notice that Jeremy hadn't had the book when he'd arrived, and went to play.

An hour and a half later, all three boys had stick swords and leaf eye-patches. Their shoelaces had been removed to use as string, and once they had all taken out one shoelace, it seemed silly not to take the other out, and their shoes wouldn't stay on. And pirates didn't run around in socks, so they came off too. Fred and George both had mud warpaint on their faces, and all three of them were climbing over the play castle yelling about enemy ships and walking the plank. Even if two of the boys were wizards, and the other was a muggle, some childhood things were rather universal, and pirates is one of them.

When Molly and Marcus finally realised how long they had been chatting (they'd started talking about cooking, and then they were swapping recipes and then they got carried away) and called for their kids, the three boys that turned up were all dusty, waving sticks and eye-patches and grinning madly. Marcus gave a shocked laugh at seeing Jeremy, who was still missing his shoes and by this point had also lost his jumper (the pirate ship needed a flag). Molly had her first twinge of misgiving.

Nevertheless, the friendship continued. The next play-date was at the lake behind the burrow, because Fred and George asked and everyone had promised to keep brooms on the ground and everyone away from the house. Molly made a picnic for the boys and told them not to go further than the shallow end of the lake. She made sure that Jeremy could swim, just in case, and left them all in swimming costumes.

As soon as she was out of sight, the hunt for swords began and eye-patches were pulled out again. These were a little stronger than their previous ones, now made from cardboard and string rather than leaves. Once that was done the old row boat was pulled out, and the adventure was on.

And so it continued. On the fourth play-date, Jeremy pulled his first prank. It was a small affair with water balloons, but Fred and George celebrated it loudly, and Jeremy was just realising how much he enjoyed having friends and that running around and getting covered in mud was actually rather fun. On the seventh play-date, there was an incident of accidental magic.

Usually, this would have resulted in a quick owl to Arthur who would have quietly arranged for the obliviaters to deal with the muggle involved, but this time, there was no adult around. And it wasn't Fred or George's magic. They were in the woods (the pirates really were hunting for buried treasure this time) and a rotten branch dropped on Jeremy, and should have knocked him down. Instead, it bounced off his shoulder and he looked a bit nervous. Fred and George of course, handled it with subtlety and gentleness.

"Hey, you didn't tell us you're a wizard!"

"All this time we thought you were a muggle!"

Jeremy stared at them, this wasn't quite the reaction he'd expected. Most of the time when something weird happened to him, people didn't believe him, even if they'd actually seen it. And he'd never heard the term muggle before.

By the end of the visit, Jeremy had been informed of the meaning of both muggle and muggle-born, and of a great many things in the wizarding world, most importantly of course, broomsticks. They had also decided that they weren't going to tell anyone that Jeremy was a wizard. That would be boring. Instead, the sleepover was planned.
