There really is no more evil place than the Slytherin common room. Not only is the place gloomy looking to begin with, but if Dumbledore had any clue of what really went on there he would probably choke on his acid pops.
A week had passed since Sirius had changed house, but he still had trouble fitting in. He passed some fifth year who was boiling cats.
"Is that your dinner?"
If the fifth year then had not been attacked by a cat and then struggled to get it off if his face, he would have given Sirius a long condescending look.
A couple of girls were plucking the feathers of a starling for their evil potion.
"Wotcha making?" Sirius asked them.
One of the girls rolled her eyes and sarcastically said: "Pea soup"
"Oh. What are the feathers for? Fibres?"
The girls glared at him until he went away.
Spotting a cage of canaries and a cage of cats in a corner, he couldn't resist the temptation of opening both to see what would happen.
For one, it got really noisy. And painful. And tons of cauldrons were knocked over. People ran at every direction, not wanting the potions to corrode their skin. A couple of seconds later only Sirius, Narcissa and Lucius remained.
"Tisk, tisk, tisk…" said Narcissa. "Why must you always make a mess wherever you go?"
"I couldn't resist"
"It's not fit for a Slytherin to release the ingredients" said Lucius.
Sirius went to the window and gazed at the far octopus.
"I don't understand. Why does it feel like I don't belong here? I know it doesn't make sense…"
"I'm sure it would make more sense if you sang about it" said Lucius.
Sirius thought that was a jolly idea.
Music begins:
(Tune: Go The Distance I)


Sirius:
I have often dreamed of a far off place
Where mischief and mayhem will be waiting for me
And the girls will cheer when they see my face
And I get the feeling that it's where I'm meant to be
Wanna find my way
Wanna prank the distance
Wanna misbehave
And do stuff that's wrong
I know every mile
Would be worth my while
But the old hat told me that it's here that I belong

"Yup, now it makes sense, just as I predicted" said Lucius just when Narcissa came back (no one had noticed her leaving) with a tie. A gryffindor tie.
"We don't quite understand, but when we stumbled upon you last week we found this lying next to you" she said, handing the tie to Sirius. "It even has your name on it, so it's no doubt it's yours"
"But it has the Gryffindor colours"
"Yes well you don't remember this but you were originally sorted into Gryffindor"
"So that's why everyone keeps asking me why I'm suddenly in Slytherin…"
"Anyway, you should probably talk to Dumbledore about this. Remember, the password is Tangerine Bean"
"And it's a long way so I packed you some lunch and some mittens" said Lucius, handing Sirius a box.
"But we just had dinner-"
"Like I said, it's a long way"
Sirius headed for Dumbledore's office immediately. Since it was such a long way, he started singing again:
(Tune: Go The Distance II)

Sirius:
I am on my way
Wanna prank the distance
This was really far
Why is it so long?
I hope all these miles
Will be worth my while
Gonna do all that it takes to find where I belong

He stopped singing just as he reached the door to the office. When he got no response when knocking on the door, he just took the liberty to go inside to see if there was anyone in there.
Dumbledore wasn't there, but it appeared as a wax figure of him was sitting by his desk in his place. Sirius figured that since Dumbledore kept it there, maybe it had the magical ability to communicate in his place as well.
"Oh mighty Dumbledore"
He wasn't sure how to address him.
"I'm kinda having problems with…fitting in…ish"
"Why hello there Sirius, I didn't see you come in! Want some acid pops?" said Dumbledore all of a sudden, grabbing a bowl of acid pops and offering it to Sirius, who was so scared he started running around in circles, screaming 'The alien puppets are taking over the earth god help us all' and didn't stop until Dumbledore shot a calming spell at him.
"I'm not a puppet, I was just sleeping. I sleep with my eyes open, you know. Anyway, you're having trouble fitting in you say? Well, I'm not surprised because you are actually a Gryffindor after all"
Sirius gasped.
"But they are my sworn enemies! I can't be a Gryffindor!"
"Well that was the house in which you were originally sorted. But then you drank the potion Severus' friends gave you, that potion almost drained you from everything that makes you a Gryffindor. Minerva is so sorry she didn't take you to the Hospital Wing that day she encountered you with that bottle"
"So…Can't I just be sorted back?"
"I'm afraid it's not that easy" said Dumbledore, gazing at the far distance. "You see, the hat is programmed not to sort anyone more than twice, or else everybody would wanna be resorted as soon as they were arguing with a best friend or having a crush on someone from another house. But there is one way"
"I change house without the hat's permission?"
"No I'm afraid that's impossible"
"Why? It's just a hat"
"Just a hat…" Dumbledore chuckled and Sirius' naivety. "Anyway, there is a way. You must prove yourself a true Gryffindor"
"But how?"
"You must seek James Potter, nobody is more Gryffindor than he is"
Sirius immediately skipped out of the office and all the way to the Gryffindor tower, while singing merrily:
(Tune: Go The Distance III)

Sirius:
I will beat the hat
I can prank the distance
I will face the girls
God I hate this song
Wanna be a brat
I can prank the distance
Gonna find that Potter and the place where I belong
