Well here's Chapter 2! Enjoy!
Hermione woke up with an aching all over her body. After getting past the pounding in her head, the chill from the ground beneath her started seeping through her shirt. Cold floor? As far back as she could remember, the Burrow had never been this chilly; what with Mrs. Weasley's constant warming charm during the autumn and winter months. She sat up and looked around, trying to get her bearings. That's when she noticed Fred and George sprawled out on either side a couple meters away from her. The former was groggily getting up, just as she had, and was looking around. "Fred!" she whispered. Immediately his head snapped to hers and they both made to get up off the cold ground.
"You all right?" he asked her while rubbing her arms to try and bring some warmth to them. Fred realized what he was doing and stopped abruptly; thanking Merlin it was night out so his blush wouldn't be noticed. Wait. Night? Could've sworn we left the shop during noontime.
"Fred. We're still in Hogsmeade." Hermione whispered, and then noticed something else that made her eyes widen. "Fred! The shop! Your shop is gone!" Fred turned to where her wide eyes were looking at. Indeed their shop was no longer there, but in its place the seemingly new Zonko's, not looking at all like it had when they had bought it off of the aging Mr. Zonko.
A groan came from their left and they realized they had forgotten about poor George. Hermione and Fred rushed over to the confused looking George. Rubbing his face with both hands, they barely made out what he said, "Wha – 's goin' on?"
"Don't really know, Georgie. Think you could take a shot at guessin'?" Fred asked with a slight smile. George just groaned in reply.
Meanwhile, Hermione had been trying to figure out how they had ended up here. Wherever "here" is, she thought wryly. Twins play prank. I pass out. I wake up. Can't move. No Pepper Up potion. Twins help me to the fireplace. Fred throws powder. Blue flames. Why the blue flames though? What on earth would affect the Floo powder to make the flames blue. Unless…
"Fred! Give me your hand!" Hermione cried to the stunned twin. Reaching out to grab her thinking she wanted to hold his hand. "Err. That's not exactly what I meant." She said giving a nervous laugh and thanking Merlin no one could see her blush. Fred instantly let go of her hand and turned to look the other way, but only met the smirking face of George. Hermione took out her wand and muttered 'lumos'. Grabbing Fred's hand once again she turned it around palm up and waving her glowing wand across it. "I knew it! Look, your palm and fingernails have blue powder still stuck to them. You didn't use the floo powder." The awkwardness left them completely at the sight of an explanation.
"Not to put a damper on things, Hermione, but Fred also threw the powder on you. It could just be the residue left behind from that." George said, adding his two cents.
The smile she gave both the twins told them that she had figured everything out. "I thought of that, too. Fred's a lefty, right?" She looked to said twin and continued when he confirmed her statement. "So he would have used his left hand to throw the powder at me when you were going through with your prank. When I woke up, however, and couldn't walk, Fred grabbed me on my right side, leaving the only hand open for use his right. That is the hand he grabbed the floo powder, or what he thought to be the floo powder, with." She grabbed his left hand and sure enough, there were specks of blue left on that hand also.
No one spoke for a few minutes; they were still digesting everything that had happened so far. That is, until Fred went and broke the silence. "George?"
"Yes Fred?"
"Did you clean out the excess floo powder in the fireplace like you said you would?" He asked in the same monotonous voice. George looked up at them both with wide guilty eyes. Fred let a breath of air he hadn't realized he was holding. "I bet the Pass-Out Powder reacted badly with the floo powder that was already in the fireplace."
The trio once again lapsed into silence. Hermione, this time, was the one to break the silence. "Well, it seems that the closest thing we can get to normality is Hogwarts, so I guess we should start there first." The twins nodded their heads in agreement.
"We can take the passage that goes into Honeydukes." George chimed in. They all made to go when Fred grabbed Hermione's hand to signal her to stay back. George kept on walking, knowing exactly what was going on with his brother before he even did.
"Listen Hermione, I'm really sorry for getting you – us – into this whole thing. I didn't mean for any of this to happen. I wasn't even one hundred percent sure I was totally okay with pranking you like we did before. I'm just, real sorry." Hermione stared back at the bashful twin. An apologetic Fred? A hyper Fred? Yes. Mischievous Fred? Definitely. Hungry Fred? No problem. But a contrite Fred? Never head of it.
"Yeah, uh, sure. You know, after helping Harry defeat Voldemort, life can kinda get a bit boring. So I guess I should be thanking you." She responded with a small smile. "C'mon. George's going to be wondering where we are."
They clambered out of the passageway and into the dark halls of Hogwarts. She couldn't quite place it, but there was a different feel to it. The trio made their way to the Headmistress' office, but was stopped by the stone gargoyle that kept them from going any further. They stared at the gargoyle for a few seconds before George started to try and guess the password.
"Cockroach Clusters."
"Lemon Drops." Fred tried.
"Bertie Bott's Ever-" Hermione at just started, but a welcoming, kind voice supplied the correct password.
"Sugar Quills, actually." Said a quite calm, and quite a bit younger, Dumbledore. The twins and Hermione could only gape at their once Headmaster who they knew to be dead, killed by the late Severus Snape. "Come now; You surely must have quite the urgent situation that requires you to come to me at this time of the night. And to be honest, I can't say that I recognize you." He said while ushering them into his spacious office.
Once they had seated themselves in the chairs that were summoned by the Headmaster, the twins kept quiet, giving Hermione the floor. "Before I begin, sir, I would like inquire what year it is?"
"It is August 31, 1977, my dear." Dumbledore told them.
"Well, you see sir, by some sort of accident involving one of their," she indicated the twins on either side of her, "inventions that reacted badly with floo powder, we ended up here. We are actually from the year 1998." Hermione hadn't really processed what she had just said, and when it finally got through to her that they were sent over twenty years into the passed, she grabbed Fred's hand for comfort.
Dumbledore didn't react right away to their current predicament. Hermione had gone ghostly pale and Fred's thumb was rubbing soothing circles around her hand while George put a brotherly arm around her shoulders. Finally, the wise Headmaster spoke. "I will contact an Unspeakable I'm friendly with who specializes in cases with time and time travelling and I will let him know about your situation. As of now, there is not much I can do but provide a home for you three. You all look like you could be in your seventh year so that is where you will be staying until we can get you sorted out. No what are your names?"
"I'm Hermione Granger and they are Fred and George Weasley." She told him in a shaky voice, but other than that Hermione looked like she was recovering from the shock. Although, she still held tightly onto Fred's hand, but George's arm had retreated back to his body when he saw she was better.
"Granger. I don't think I've heard of that name; I presume you are Muggle-born then? Yes, yes, of course. Now Weasley, that could be a problem. There are so many of you!" he said with a small chuckle, making the twinkle in his eye even more prominent. "Perhaps change it to Warren?"
The twins nodded in agreement. "I will take care of all your school supplies, but which House were you sorted into? I know how stressful the Sorting can, and I know you wouldn't want to go through it a second time."
"Gryffindor, sir." This time it was Fred who had spoken, a hint of pride in his voice when proclaiming their old House to be Gryffindor.
"Very well. You will be introduced tomorrow as transfer students after the Sorting. The house elves should have prepared a room for you by now and I will summon one for you to take you there. If there are no more questions, I will be bidding you goodnight." He said to them. They left the Headmaster's office and waited outside for the elf.
