DISCLAIMER: Anything you can recognize, I do not own. I hope you enjoy the story. I really like pairing Harry (whether female or male) with anyone in the Weasley family (except for Ron and Ginny).

Fred saw Harry leave the great hall at lunch. She caught his eye as she left and he couldn't help but grin seeing the challenge in them. He told his twin he would be right back and took off after the girl who brought him so much amusement. "So we still on for after classes?" he asked the moment he reached her side.

She gave him a grin full of mischievousness, "why wait till after classes," she returned challengingly.

"A girl after my own heart," he said with a chuckle. "Not worried about detentions and point loss?"

"I have potions, I will probably get fewer for skipping then showing up and then I have history. Honestly pointless class in all," She said easily. "I've not been here long but I already know quite enough about both classes professors. Not worth the time nor the bother. But if you have to go to classes like a good boy we can wait."

"Ohhh still risking the dungeon bats wrath. That's a risk on a good day and a bad," Fred said amused, "And one thing no one has ever accused me of is being a good boy. To the forest we go then?"

"Sounds like a plan, lead the way Fred," she said as he took her hand and they slipped through the school. Avoiding professors and other students as they went. She found herself amazed by the secret passages he showed her or the nifty hiding spot he found once they heard his older brother. Percy the Prefect. She knew without a doubt in her mind that this would be brilliant and they hadn't even entered the forest yet.

*GEORGE*

It was about ten minutes after Fred had left the great hall that George knew there was a problem. He was clearly not going for a quick bathroom run. Still, he waited thinking that his twin was likely to return at some point. As the great hall emptied however, George checked his watch realizing that Fred was definitely not coming back and if he did not go to class then he'd be late. So, he made his way to transfigurations and took a seat beside Lee.

The other teen looked to him confused glancing at the empty seat on Georges other side. George gave a slight shrug as class began but as the professor began attendance, she easily noticed the missing twin, "Mr. Weasley, where is your twin brother?"

"Well you see..." he started before cringing wishing he had thought up an excuse before entering the classroom but he had not expected his twin to skip without him. "I could give you this brilliant lie and say he's in the infirmary, off fighting the giant squid, being lectured by Percy or something but I got no idea. He left lunch, said he'd be back and never showed so I can't answer you."

Now everyone looked there way startled, one twin without the other was just impossible to see or really think about. Many of them had never witnessed them separate. When one got sick, the other usually did as well or faked it well enough they could hang out in the infirmary together. For George not to know where his twin was, was shocking to the lot of them. Even to the professor though she quickly caught her baring's, "I see, please inform him he has a detention with me tomorrow at 5."

Lee nudged George as class started, discretely getting his attention to stay out of sight of the lioness. "He didn't by any chance get attacked by Slytherins," Lee asked worried about the possibility.

That thought never dawned on George, but he quickly remembered what he saw Fred following or rather whom. A first year and from the looks of it, it had been the potter girl. George remembered the mention of the girl in the astronomy tower and guessed the two were related. "No, I don't think so," George stated, he'd feel through the twin bond if he was in pain. "I think he just decided to skip today or got distracted."

To others it would be strange but Lee knew both twins well, he knew Fred was the one who had a quick temper, loved chaos, wanted to fight and was always willing to do something for a thrill. George was quieter, more studious, goal oriented and was not as willing to get into real trouble.

Still usually they were always together so it was strange for him to see. He relaxed though, under the assurance it was unlikely that he was attacked.

*Fred and Harry*

As the two students approached the forest, Harry gave it a good look over. She hadn't really gotten the opportunity to observe it so early in the year. It looked fairly mundane to her. Sure the trees seemed slightly larger but she was expecting something more from a magical forest. Something…less muggle. "Seems rather tame," Harry mocked as they entered through a break in the trees.

Fred chuckled having thought the same thing at first glance, "the real nasties tend to be further back," Fred admitted, "Up here they are all sweet and cuddly." Fred dodged a plant that went to take a bite out of his leg much to Harrys surprise. She knew magical plants were a bit more…sentient on levels but to see a plant try to take a bite out of someone's leg reminded her she wasn't in the muggle world anymore. "See sweet and cuddly," Fred offered with a cheeky grin.

She laughed since few would find a joke in a plant trying to take off his leg, but he just easily laughed it off. "You're amusing," Harry stated jumping onto a rock so she could get a better look around.

"I try," Fred returned as she jumped back down. "So, the forest is our playground, anywhere you want to go?"

She glanced around, they were now deep enough that she couldn't see the school through the dense trees, "surprise me."

Fred led her deeper to a spring thinking that of all people, she might like the area. "It's not thrilling but this is one of my favorite places in the forest. If you go deep enough in the hot spring you reach these underground cave systems. Fucking brilliant. The walls glow because of the crystalized rocks."

He caught her interest, glowing rocks in an underground cave. How could that not be interesting? It was something magical. Maybe not plants trying to take your leg off magical but it was still something she wanted to see. "How deep?"

"You got to drop down about fifteen feet and it's a good two-minute swim. Takes holding your breath as long as possible. George hates it, he hates not being able to breath that long but if you reach it its brill...then if you don't then well, I am sure someone will find your body eventually."

Not bothered by the end of his comment, she decided that she wanted to see the cave not caring about the potential dangers she would face below the water. She took off her shoes, overcoat and sweater not caring about modesty. "So you going to show me?"

He grinned, he could never convince George to go down after the first few times when he almost never made it. It was not as interesting without someone to share it with. "I should hope you will excuse the impropriety, but slacks slow us down. Too heavy."

The amused look she gave him made him want to laugh realizing exactly what was on her mind. "Ahh, I see so that's why you like it here," she said amused, "do you show it to all the girls."

He chuckled not offended by the thought at all, "you're the first but sweetheart, in a few years that may be my interest but your eleven."

"Twelve," she corrected. "I was born September 30th, I am twelve."

He grinned since that made a lot of difference, that one year. He was after all only 13. Even George wouldn't be able to complain too much about propriety and morals. "Well then, strip away love. Ladies first."

She removed her shirt revealing a black braw and her pants quickly followed, not at all bothered by him seeing her near naked. She seemed to have no moral boundaries. Then again, neither did Fred which just made the situation all the more amusing to them both. "Now your turn pretty boy."

He chuckled taking off his pants and shirt. "So I should have asked, can you swim?" It was a second thought but surely she wouldn't have been so easy to attempt it if she never swam before.

"Yeah," she said, "I use to break into the public pool at night to swim."

For some reason, likely due to where they were, that fact did not surprise him. The illegality of the action didn't bother him. It just made him more interested. "A rebel then, I am suitably impressed, how long can you hold your breath."

She scowled slightly as she answered but it was just barely visible beneath her calm mask, "my cousin had a thing for holding me underwater, 3 minutes at most though."

Fred's eyes narrowed slightly, he liked a joke, a prank and a good fight but you did not do something like that to another person…especially someone who shared your blood. That crossed a line even Fred would never dream of crossing. "You should hex him," he said as his eyes trailed to her back and he could see the scars marking her skin. He had a feeling it was not just her cousin who was the issue. "Do you live close to the git?"

"I live with him, my aunt and uncle," she answered slipping into the water not bothered by her gaze. She managed to be surprised, as it was the beginning of October, she expected the water to be chilled as the air was. "This is rather warm."

He took that as a very clear notice that that was as much as she was saying so he too slipped into the water. "Hot springs, there are a lot more, deeper in the forest but these ones are only mid warm and they have the caves."

She nodded, "alright then, lead the way."

He took a breath and dived under, she followed him as they swam deep and just as they were in the most need for breath, they swam upwards and breached the surface gasping. "2 minutes 23 seconds," Fred said pulling himself up onto the rocky ledge. "You good?"

She nodded still catching her breath as he helped her up. "That was awesome," she said finally before looking to where they were. "Merlin," she said amazed "this is..." There were absolutely no words to describe the room she was now in.

All around them were crystal lined walls in all colors, they seemed to glow in the darkness of the cave giving it an eary light. Never had she imagined witnessing something so perfect. "Pretty isn't it," Fred asked finding it as amazing as he always did. He could come down here a thousand times and he would never get tired of seeing the beauty in the cave.

"Yes," she agreed, "what's deeper?"

He cast a Lumos, he was really finding himself liking this girl. "No idea, I haven't gone too far past here, want to check?" He had never gone past it since George thought it was too dangerous, too much of a chance of cave ins and he had only been there three times since it was not as fun alone. Not as fun to explore when he couldn't share it with his brother.

"You know it," she agreed as they went deeper through more crystal lined walls. The rocky ground cut at their feet but they ignored it as they went deeper, searching out anything, knowing that around any corner could be a dangerous creature to await. It just made the adventure all the more exciting.

"Another spring," she said when they ended up inside what seemed like a larger room with no glowing crystals. The caves seemed to branch off into dozens of other stone paths. It made them curious as to what had been down here or rather whom. Was the cave natural or built by people from the school over years.

Fred stuck his foot in the water, it was fairly warm. Similar to the spring that they had just swam into, "all the forests hot springs and water networks must be interconnected," Fred suggested. "Want to see where the water leads?"

"Could be more than three minutes," she admitted glancing down. "To get to the top."

He flashed her a grin, to him this was the ultimate test in finding out if she was actually willing to take the risks or was all talk, "risk I am willing to take, you?"

She grinned excited by the prospect, "Sounds like a thrill," she said slipping into the water. Taking a breath, they went down and found an opening. They swam through the water and then up towards where they could see the light breaking through. To their surprise they made it out quicker than in the other.

It took a moment to acclimate themselves once their heads broke the surface and neither were expecting what they saw. Surrounding them were dozens of spiders the size of cars. She had had no idea that spiders could even grow that big. They could easily devour the two teens. "Acromentula," Fred stated quietly though he was amazed, he had heard rumors of a nest in the forest but never actually saw one. "We must be nearly in the center of their nest. I've never been this deep, they are usually vicious and deadly."

"You're telling me we are in the center of an acromentula nest," she demanded unable to believe it. She was seeing it but she couldn't believe they were in front of so many giant arachnids. For the muggle raised girl, it was an amazing site to see and completely different then what she expected.

"Looks like," he said wondering if she was bothered, most people, most sane people would be completely and utterly terrified. Knowing that fact did not however stop him from looking around amazed.

Instead of being scared, she lit up happily, "this is bloody brilliant, if we stepped out of this water we would be dead."

"You and me will get along great," he said amazed that she found the same thrill in it as he did. The potential for death bothering neither of them. It only added to the thrill.

She gave him a grin that lit up her entire face, "So this is the first date, I can't wait until the second," she said taking a breath and going under while he was still processing what she said.

"Neither can I," Fred admitted before following her.

They easily made it back to the main area. Fred checked the time again before cringing, "its four thirty, we'd best go back, or we will miss dinner and all this swimming's making me hungry." He honestly hated the idea of going back. Having too much fun. Still his twin would worry if he wasn't back. Honestly his twin already was probably extremely worried about his disappearance. He would do it again but he didn't want to worry George more then he already was. He especially did not want the professors to come looking for him.

"Alright," she agreed as they went under and out only this swim was much harder, and they barely made it up. Exhausted from there exploring. It took them ten minutes to catch their breaths before they got dressed and returned to the school.

They made it into the great hall just in time for dinner. They took a seat, beside George and across from Harrys friend. "you have a detention tomorrow and minus 10 points," Neville stated as she sat down. "Binns didn't notice."

George looked at them both realizing they had dampish hair, it made him wonder what they were up to but he was almost afraid to ask. It could have been anything. Breaking into the prefects washroom, going for a swim in the black lake or doing something that made them both need to take a shower, He wouldn't put anything against Fred. He'd probably never guess what he was really up to. "Fred, you got a detention tomorrow as well, were you together?"

"Yeah," Fred said grabbing some food not bothered by the detention. He was probably in detentions more times than he was not. "Only one there's a shocker."

Harry snickered feeling the same way, "I'd have gotten at least two if I showed up to class."

Neville cringed since he was the only friend she previously had, and he found her more rebellious moments dangerous. He did not understand why she went out of her way to cause problems or why she got a thrill out of pissing off the most terrifying teacher in the school. Every potions class seemed to be a war between Snape and Harry. How annoyed could they make the other, how long until she got kicked out of class, how many points he could take. "Mostly because you can't go without telling him to go to hell."

"Or get laid since he clearly needs it," she said causing Fred to break down and laugh.

George wondered how his twin found someone as insane as he was, he didn't know whether to be impressed or terrified. "You are suicidal."

She winked at him, "never, that's no fun, just dead and bluhhh. Very uncreative. I have far too many plans. Adventures to have."

"Going to take me with you," Fred asked with a grin.

"Anytime curfew breaker," she said lightly, her eyes brightening by the idea, remembering their previous adventure just finished. The trip to the forest. Acromentula. Crystal caves. What else could they find if they looked hard enough. She couldn't wait to find out. "As long as you show me some great spots."

"It would be my greatest pleasure," Fred said.

George and Neville shared a worry look wondering exactly what they got themselves into with there two closest friends getting to know eachother.
