AN: Hey guys! So… This has actually been bugging me for a while… So I finally gave in and decided to write it! And I have to write now since I saved it before I did anything past Hey Guys… Oh well! This should be fun!

Harry Potter entered the great hall, with a fairly large group standing around him, all of them talking to each other happily, except for the Boy-Who-Lived… Oddly enough.

McGonagall went through the names, stopping as she reached Harry Potter, noticing that there were too many people left, with only a few names on the list. As she checked the list again it shook, pushing out a new list with many of the older names put on the new one with other names next to them. So, she read them out in order.

"Granger, Hermione/Prower, Miles!" She called out, squinting as she did so to make sure she got them right.

A girl with straight brown hair, which had blonde hints to it, walked forwards, ignoring the stares that she got due to the strange twin fox tails that sprouted from… Somewhere… She sat on the stool and McGonagall placed the sorting hat on her head. After a few minutes the hat finally decided.

"GRYFFINDOR!" It roared as she headed to the table silently.

"Weasley, Ronald/Echidna, Knuckles!" Was next, the Weasley son looked normal, apart from the dreadlocks and strange spiked fists…

His head touched the hat an- "GRYFFINDOR!" Instantly the hat decided.

It kept going, many students were sorted, all of them into Gryffindor… And then, it was time…

"Potter, Harry/Hedgehog, Sonic!" She called out, before she gasped, another name appearing.

"P-Potter, Harry/Hedgehog, Modern, S-Sonic!" She called out again, adding an extra piece in as another boy stepped out from behind a pillar, revealing a much older looking, but still 11, version of the boy who lived, as everyone noted the first Harry was quite short…

"Hey there!" The taller one said with a grin. "So… Who's goin' first? Me or Him?" He asked curiously.

"I believe, that we should go in order of names…" Dumbledore said from his place at the table.

"Alright! Hey Mi-" The taller one said before stopping, looking for the first Harry, until he found him sitting on the stool already, kicking his feet in the air, barely visible under the hat.

"GRYFFINDOR!" It called out, the taller Harry took the hat and put it on with a grin, getting, "GRYFFINDOR!"

The two Harry's sat down at the table together, high fiving as they did.

"Mr… Potters, if you could come to my office at the earliest convenient point?" Dumbledore asked, clearly confused.

"Kay!" The tall one said, giving a thumbs up, the smaller one just gave a thumbs up.

1 hour later

The two Harry's entered the office with McGonagall leaving afterwards.

"So, You uh, wanted to see us? Sir?" The tall one asked curiously, remembering to say sir afterwards.

"Indeed…" Dumbledore said, watching the two closely. "I am most curious as to how there are two of you." He explained.

"Oh! Well, that's kinda complicated sir, but the short version is that there isn't. We're actually from two different dimensions or something, at least, that's the theory since I can't remember this happening. Mini-Me here is the Harry Potter of your world, and me and my friends are from our own dimension, or… Well, Mini-Me is from his own dimension, one where my eyes never went green, or learned my homing attack… We call it the Classic dimension, I'm from the modern dimension." He explained with a shrug. "So… Just call us Classic or Modern, we'll also both respond to Sonic, or Harry." He added as 'Classic' Nodded his head. "Oh, and ah, Classic's kinda mute. It's why we're from different dimensions, since I could talk at the point he's at, even before I stopped looking like him." He added again.

"Interesting… I'll have to ask you to tell me more at some point…" Dumbledore mused, letting them go to the common room.

Outside the office.

The two Sonics left the office and raced down the stairways quickly, Modern leaving smoke and a trail of light behind him as he ran, forming an aura of light. Classic ran with his legs in an infinity symbol, occasionally spinning into a ball and running along the walls before they both crashed into a painting that slammed open from impact.

"Sonic…" A voice said as Hermione rolled her eyes, reading a book as she did.

"Heh… Hey Amy…" Modern mumbled quietly, getting a silent snicker from classic.

"Why didn't you tell us you were here?! We thought something got you!" A girl asked him as she clung to his side.

"Well… I couldn't, I was sorta… Well I didn't know where I was, it was just a black void for, I don't know how long, but then I did know where I was, and I just… Went with the flow, eventually I ended up here." He explained with a shrug.

"So, do you have anything about Classic's life? We can't figure anything out since well, he's mute." Hermione said.

"Sure thing Tails." Modern said with a nod. Classic suddenly bursting out hand signs at a speed most couldn't keep up with, except for Modern and a random student who paled as she saw them.

"Uh huh… Got it, really? Wow!" Modern muttered to himself as he managed to keep up with the signs. "Ok, I got it for you." He said, writing it down so that they could read it, knowing that he'd forget something if he spoke it.

"So… How can you understand him?" Ron asked.

"Hey, remember I was mute back when I was him, and since we seem to be more like split timelines than anything, I'll bet that the change was me getting a voice and my homing attack, not to mention eyes." Modern shrugged. "I used to use sign language when I was mute, I didn't use it for ages but I still practice just in case I need to." He explained, with Classic off using Sign Language to talk to the other student that had understood him, with that student using it to talk back to him.

"Huh, looks like Classic's found a friend!" Hermione said with a smile.

"Yeah, and someone he can actually talk to, which means if something happens and I go missing or something and Classics the only one to see it, he can tell someone, if they can actually understand him that is…" Modern muttered the last part.

"What d'you mean?" She asked him.

"Well he takes shortcuts a lot, for example for certain people he'll use letters and not the full names. I'd be M, he'd be C, Knux would be K, and you'd be T, and so on. For say, Cream, he'd use CR, to tell the difference." He explained with a final shrug before heading to bed, Classic following him after signing a goodbye to his new friend, who signed back with a smile. "C'mon mini-me, time to take a snooze cruise." He said as he flopped onto the soft bed.
