A/N: Wow, thanks for all my reviews! I really do appreciate knowing that people actually read my fics. Ok, let's see what happens when the dust clears:

Chapter Two – Harry?

'What the hell just happened?' asked Fred, between racking coughs which felt like they were tearing his lungs up.

'I dunno.' George answered when his own coughing fit subsided. 'That stuff really isn't fun to inhale though!'

They raised their heads and looked around, looking for any damage to the room. Incredibly; apart from the fact that all traces of Essence of Mayfly had vanished, the Room of Requirement was totally untouched. In fact, the twins could have sworn that the room was tidier than it had been before the accident.

'We better get to our next class, Professor Snape's taking Defense Against the Dark Arts again.' said George, getting to his feet. He looked at his watch to see if they were already latebut it had stopped working.

'Oh man, his classes suck! If only we'd got the time accelerator right already!'

Grumbling to each other the twins walked out of the Room of Requirement and started along the corridors to the classroom. As they walked they began to notice, almost subconsciously, little things that weren't quite as they should have been. People they met had slightly old fashioned haircuts, or stickers and badges on their bags for bands that the Weasleys didn't recognise.

'This is weird; I haven't seen a single person I recognize. I thought we knew everyone at Hogwarts.' George noted.

'Yeah, weird…' agreed Fred thoughtfully. They turned down another hallway and saw a familiar messy head of black hair walking away from them, accompanied by a small, mousy haired boy and a boy with shoulder-length black hair who they didn't recognize.

'HARRY!' the Weasleys yelled down the corridor. The boys kept walking.

'God, is he suddenly deaf or something?' wondered Fred.

'Oy, POTTER!' George bellowed. The boy finally stopped and turned around, the twins ran up to him. 'Hey Harry, what's going on around here? Everyone looks different. You're the first person who doesn't look like they stepped straight out of the seventies or something.'

'Do I know you?' the unruly-haired boy said, looking annoyed. Now that they saw his face he did look just like Harry, but there was something in the way he held himself which wasn't right; an arrogance in his manner which Harry had never had. It was like looking at Harry with deliberate little mistakes.

'Of course you do, we're Fred and George Weasley, Ron's brothers. Speaking of which; where is Ron, and Hermione too? Who're these people you're with?' asked Fred, becoming confused.

'I don't know who the hell you are and I don't know who you're talking about, but if you don't leave us alone I'm going to hex you.' said the boy, pulling out his wand and frowning at the twins. 'I really don't have time to talk to nutters.' Without further ado the trio stalked away, leaving Fred and George staring after them in disbelief.

'Come on Padfoot, we've got Quidditch practice later, just gotta get through Divination first.' the boy was saying as they moved away.

'Who were those weirdos?' said the long haired boy.

'I dunno, but Prongs really showed them not to mess with us!' said the smaller boy, looking excited and breathless.

Behind them, the twins looked at each other.

'Padfoot? Prongs?' they whispered 'It can't be?' Reaching an instant decision they pelted down the corridor after the other boys. They skidded to a halt in front of them and said;

'If you're Prongs and you're Padfoot, are you the Marauders?' They asked, wide-eyed. 'Did you write the Marauders' Map?'

'How do you know about that?' exclaimed the mousy-haired boy, 'It's not even finished yet!'

'Yes it is; we've been using it for years.' replied Fred, pulling the map out of the pocket of his robes and activating it. He showed it to the other three boys. 'Without this George and I would never have accomplished some of our most famous tricks.'

'Now listen,' said the long-haired boy, his voice low and threatening, 'I don't know how you got that; but I promise you, if you tell anyone about it I will hex you into the middle of the next decade.'

'We're not going to say anything. In fact, we think we could give you a hand.' offered George.

'We don't need help.' said the messy haired boy stubbornly.

'Yeah, from the sound of it you're more likely to need our help. Didn't you say you'd be nothing without our map?' said the long-haired boy brutally.

'That's not exactly what I said-' began Fred indignantly, but the messy haired boy cut him off:

'Precisely. So stay the hell out of our way, whoever you are.' He said ruthlessly, before storming away down the otherwise empty corridor, his two friends behind him.

'Fine; THIS MEANS WAR!' Fred and George bellowed after them. They walked off in the other direction, their heads close together as they started planning ways to show the Marauders that the Weasleys were just as crafty as they were.

A/N: Ok, things have got more interesting! Coming up next; Fred and George figure out who the Marauders are, as well as when they are and the prank war begins!
