A few minutes into the journey, the door slid open to reveal the youngest red head boy.

"Excuse me, you guys mind?" he asked shyly "Everywhere else is full."

"I don't mind," Jack said looking to Harry who shook his head too.

The red head slipped in keeping his eyes on Harry, and sat down. When he realized he was staring, he quickly looked out of the window, pretending he hadn't looked.

Smirking, Jack started playing with a yoyo he managed to snatch from the Pole, seeing a black mark on the redhead's nose.

"Hey, Ron."

The twins were back.

"Listen, we're going down to the middle of the train – Lee Jordan's got a giant tarantula down there."

"Right," Ron mumbled.

"Harry," said the other twin "Did we introduce ourselves? Fred and George Weasley and this is Ron our brother."

"I've heard about you," Jack spoke up grinning, getting their attention "My Uncle says you're this generations trouble-makers at Hogwarts. Mind if I join you in some pranks?"

"Trouble-makers?" George asked astonished "You hear that Fred his Uncle think we're trouble-makers."

"I know can you believe it?" Fred asked being just as dramatic "For your and you Uncle's information... um..."

"Jack Frost," Jack said helping them.

"Right. Well Frost, for your information, we don't cause trouble," Fred finished.

"Yeah it just follows us around," George said.

"So you really were joking about that toilet seat thing back there?" Jack asked referring to what they said to their mum.

"Well, ok so we may be a little hard to handle, but we never do anything that can harm a fellow living creature. Besides, Peeves is way worse," Fred said defending himself and his brother.

"Who's Peeves?" Jack asked sure he knew that name from somewhere.

"He's a Poltergeist who has been living at Hogwarts for no-one-knows-how-long," George explained.

"I think my mum may have said something about him once," Jack said remembering once when Tooth was on a tooth-collecting frenzy and warned her mini fairy's about him.

"Well, see you all later then," they said and left.

"Bye," the three boys said, as the twins left, closing the compartment door shut.

Once it had, Jack turned to Ron.

"You're scared of spiders aren't you?" he asked in the most friendly way possible, getting a small nod from Ron.

"How do you know?" Harry asked.

"My family have some... Experience with handling and controlling fears," Jack said then pointed out some symptoms like clenched fists, avoiding of the eyes, and fast paced breathing.

Once that was over, Ron looked over to Harry and blurted out "Are you really Harry Potter?"

Harry nodded.

"Oh – well, I thought it might have been one of Fred and George's jokes," Ron explained "And do you really have the... the..."

"The what?" Harry asked confused.

"Scar..." Ron whispered.

Grinning Harry pulled his hair back to show his lightning shaped scar.

"So that's where You-Know-Who...?"

"Yes," Harry said calmly "But I don't really remember any of it."

"Nothing?" Ron asked eagerly.

"Well, I remember a bunch of green light, but nothing else."

"Wow," Ron said staring at Harry again then turned his attention out the window again.

"Still up for our bet Harry?" Jack asked thinking it was time to change the subject.

"You were serious about it?" Harry asked.

"What are you going on about?" Ron asked.

"Back in Diagon Alley, we met this prat who said 'imagine being in Hufflepuff, I think I'd leave...'" Jack said doing a perfect imitation of the boy "So after we ask Hagrid, he was with Harry getting his stuff, what Hufflepuff was, and he explained and when he said that that was the house for o' duffers, Harry betted himself that he'd be in that house, and I challenged him on it." Jack said coming to an end.

"It's only three sickles..." Harry said rolling his eyes "Why do you care so much?"

"It's not about the money, Harry," Jack said grinning "It's about proving you wrong."

Rolling his eyes Harry then turned to Ron and changed the subject again.

"Are all your family wizards?"

"I think so," Ron said smiling, liking this Jack Frost "I think Mum's got a second cousin who's an accountant, but we never talk about him."

"What about you Jack?" Harry asked "We didn't get to talk about families back in Diagon Alley."

"I've had a few families," Jack said not wanting to get into this too much "My birth family, died when I was just a kid, got caught in a blizzard one night. So with no one to look after me, I chose to live life on the streets for a bit. I'll spare you some sob stories about how lonely it was and of some of the wrong people I spent some time with, anyway a couple of years ago, my new family adopted me and they were the ones at the station."

"Well either way," Harry said "You both must know a bit about magic already."

"I heard you went to live with Muggles," said Ron "What are they like?"

"Horrible," Harry said right away then said "Well not all of them, my aunt, uncle and cousin are though. Wish I had three wizard brothers..."

"Five," Ron corrected him, for some reason looking gloomy again. "I'm the sixth in our family to go to Hogwarts. You could say I've got a lot to live up to. Bill and Charlie have already left – Bill was Head Boy and Charlie was captain at Quidditch. Now Percy's Prefect. Fred and George mess around a lot but everyone likes them and they still get pretty good marks. Everyone expects me to do as well as the others, but if I do, it's no big deal because they did it first."

As Ron said his speech, Jack was getting minor flash backs to when his was still human. In the 1700's there were a lot of big families. And as Jack thought about it, he could remember having a couple of older siblings himself.

"You never get anything new, either, with five brothers. I've got Bill's old robes, Charlie's old wand, and Percy's old rat."

Ron reached into his jacket pocket and pulled out a fat grey rat, which was asleep.

"His name's Scabbers but he doesn't do much, well except sleep. Percy got an owl for becoming Prefect, but they couldn't aff – I mean, I got Scabbers instead."

Sensing that the speech was over Jack said what was on his mind.

"Being part of a big family isn't something to be upset about, just means you have more people to play with. And you shouldn't try and be a second anyone. Just be yourself."

When all he got were looks of confusion, Jack explained.

"Why worry and bother about being them, when you are already perfect at being yourself?" Jack asked "Besides isn't it great to be different and be exactly who you are?"

Feeling a little better, but still not wanting to say anything, Ron looked out the window again.

"I don't think there's anything wrong with not being able to afford an owl," Harry said "Until a month ago I didn't even have any money, or anything that belonged to me myself. They were all Dudley's first. And I never got any real birthday presents either."

"But you got Christmas ones, Easter eggs and Tooth Fairy money right?" Jack asked knowing that at least Sandy would do his job right.

"A few, but not as much as Dudley, and the numbers got smaller as I got older." Harry said then went back to telling Ron about not knowing anything.

Thinking on what to do, Jack looked into his trunk and pulled out some parchment and ink and a book to lean on and wrote a letter to the Guardian asking for an explanation to this news.

As Jack was finishing, saying to himself he'll send it with the 'I'm here' letter he said he'd send to them when he got to Hogwarts, the door slid open and a smiling dimpled woman was there with a trolley of snacks and sweets.

"Anything off the trolley dears?" she asked.

Harry and Jack got to their feet and grabbed their money bags and went outside, Ron muttering he brought sandwiches.

While Harry looked confused and bought some of everything, Jack asked if there was anything that didn't have sugar in it.

"I've got some butter and ham sandwiches here if you like," the witch said kindly "But that's about it."

"Just my mum isn't all that keen with me having sugary things," Jack said weighing his options. In the end he bought the sandwiches and a few chocolate frogs and a pack of Bertie Botts Every Flavour Beans.

When he got back inside the compartment, Ron and Harry were digging into Harry's sweets, Ron's sandwiches, being forgotten.

Smiling Jack looked at the chocolate frogs.

"These aren't real frogs are they?" Harry asked.

"It's just a spell," Ron said "Besides it's the card you want. I'm missing Agrippa."

"What?" Jack and Harry asked together.

"Oh right. Well each pack has a different card inside them to collect, and each card is of a famous Witch or Wizard," Ron explained "I've got about 500 myself. But I haven't got Agrippa or Ptolemy."

"You mean these guys?" Jack asked lifting out two cards from his packs.

"That's them," Ron said nodding then was confused when Jack held them out to him.

"You want them don't you?" Jack asked smiling.

"Are... Are you serious?" Ron asked looking as if it were his birthday, getting a grin and a nod from Jack. "Thanks..."

"So this Is Dumbledore?" Harry said looking at his card.

"Don't tell me you've never heard of Dumbledore..." Ron said reading his cards.

Smiling Jack took a bite out of his sandwiches.

"Hey he's gone?" Harry said looking amazed at his card.

"Well, you can't expect him to be around all day, can you?" Ron asked.

"Well, no, but in Muggle photo's they just stay put, right Jack?" Harry asked looking for back-up getting a nod from him.

"What? They don't move at all?" Ron asked sounding amazed "Weird."

Once Jack had finished his sandwiches, he moved to his Bertie Botts Every Flavour Beans.

"You want to be careful with them," Ron said his mouth stuffed with a liquorice wand.

"Why?" Jack asked unsure he wanted them now.

"When they say 'every flavour' the mean every flavour," Ron explained, Harry listening in as well. "They do all the usual things like orange, and lime, and chocolate and peppermint. But they also do spinach, liver, and tripe. George swore he got a bogey flavoured one once."

As Ron finished, Jack took a small lick of the brown bean he was holding.

"AGH! THAT'S DISGUSTING!" Jack cried and threw the bean into the empty sandwich box "Cow-Pat..." he said looking around for some water.

"How on earth, do you know what cow-pat tastes like?" Ron asked giving him some water.

"One of the years I was alone," Jack said not sure if he wanted to tell them this "I was in a farmer's field camping for the night, having dinner. I went into my tent to get some extra lights, because it was getting dark, and well..." Jack said blushing seeing the others turn green. "Thinking I only burnt it I... Yeah..." Jack said leaving it at that.

In less than five seconds Ron and Harry burst out laughing.

"Wow, man that has got to be some of the worst luck I have ever heard of!" Ron said calming down a bit.

After eating the rest of the good beans and throwing the unwanted ones in the sandwich box, there was a knock on the door.

It was the round faced boy from the station, looking a bit upset.

"Excuse me, but have you seen a toad at all?"

"Sorry," Harry said shaking his head.

"I've lost him!" he cried loudly "He keeps running away from me!"

"I'll help you look for him," Jack said getting up and getting his wand out.

"You will?" the boy asked beaming.

"Yeah, come on he can't have gone far," Jack said "He's got to be somewhere on this train right?"

*o*

After around three quarters of an hour going up and down the train asking everyone they could if they had seen a runaway toad, unfortunately not getting any luck, Jack and Neville went back to their compartments, Jack seeing three unknown boys inside his one.

Well two unknown ones and the boy from Madam Malkin's.

"Oh, you're going to fight us are you?" the boy sneered, not noticing Jack come in.

"Unless you get out now," Harry said.

"But we don't feel like leaving, do we boys?" the blonde asked the two gorillas either side of him "We've eaten all out food, and you seem to have some left."

As the boy on the right was reaching for a chocolate frog, Jack spoke up, making the three boys jump.

"You know what, your right," he said going to his side of the compartment and tipped the discarded beans into an empty box, telling Harry and Ron to be quiet. "Here you are."

"Now at last, someone who knows how to show loyalty to his fellow wizard," the boy said saying his name was Draco Malfoy.

"You're welcome," Jack said not shaking the boys hand "If I were you Draco, I'd have the brown one first. Brown's the colour for chocolate right?" he said smirking looking over to Harry and Ron who were having trouble keeping their laughter inside them.

Spitting it out he swore and asked what it was.

"Just a Bertie Bean," Jack said shrugging "If you don't like them then kindly hand them back and leave."

Snarling a little they left, and good thing too because Ron and Harry couldn't keep their laughs inside themselves much longer.

"Man I really hope you and my brothers don't gang up on us with your pranking Jack," Ron said whipping tears from his eyes.

Seconds later, a girl with brown bushy hair appeared sounding like a mother when she asked "What has been going on?"

But all the boys ignore her as Ron asked after calming down "You guys have met Malfoy before?" and Harry explained all about Diagon Alley.

"Ah... he's the prat," Ron said in understanding explaining about their family being supporters of You-Know-Who.

"May we help you?" Jack asked the girl.

"You guys had better hurry up and change into your robes," she said, again sounding like a mother in Jack's opinion. "I've just been up the front to ask the driver and he says we're nearly there. You haven't been fighting have you? You'll be in trouble before we even get there!"

"Hey, 'Mum', none of us has been fighting alright," Jack said pointing his wand at her "But if you don't back off I might do something about that hair for you."

"All right - I only came in because people outside were acting very childishly..."

"Newsflash pigtails we are children!" Jack said the compartment getting a little colder "Now would you mind leaving so we can get changed?"

"Fine," she said turning to leave, then stopped and looked at Ron "You've got dirt on your nose by the way. Did you know? Just there..."

And finally she was gone.

"Good riddance," Jack mumbled putting his wand away and pulling out his robes "Whatever house I'm in I hope she's not in it."

"Hey Jack you alright?" Harry asked carefully.

"Huh? Oh, yeah I'm fine," Jack said "I just... Don't like being accused of things that I didn't do. I've had some... bad experiences with things like that and my family when we were getting to know each other."

Nodding, Harry and Ron dropped the subject, and silently, they all changed into their robes.

After the three of them were changed, a voice echoed through the train saying they would be arriving in five minutes and asked for everything to be left on the train.

Jack helped Ron and Harry to stuff their pockets with the remainders of Harry's sweets, finishing as the train came to a halt.

One by one, doors were opened and people were stepping out onto the platform.

A lamp could be seen, and a familiar voice was heard calling "Firs'-Years! Firs'-Years over here! All right there Harry? Jack?"

When all the first years were gathered together, Hagrid led them to a fleet of little boats sitting on top of a large lake.

Seeing it made Jack come to a standstill.

"No more than 4 to a boat," Hagrid said then saw Jack "You ok there Jack."

"Huh uh, I'm fine," Jack said trying to stay calm, "Just don't have all that much good experience with large lakes."

"It will be alright," Hagrid said gently "As long as you don't rock the boat too much, or lean over the side too far you'll be fine."

So with that Jack got into the boat Harry, Ron and Neville were in.

"Everyone in?" Hagrid asked getting into a boat all to himself "Right then... FORWARD!"

All at once, the boats set sail across the lake, everyone amazed by how wonderful the castle was.

"Heads down," Hagrid called getting everyone to duck as they entered a cliff.

After going through the tunnel that seemed to go right under the castle, the boats stopped.

Carefully everyone got out of the boats.

"Oy, you there! This your toad?" Hagrid asked calling Neville back.

"Trevor!" he cried going to collect him.

Once they were all out, they climbed up a passage way to the what Jack suspected was the back door to the castle, then up a flight of stone steps, coming to a stop in front of a pair of large oak doors.

"Everyone here? You there! Still got your toad?"

Hagrid raised a gigantic fist and knocked on three times on the door.
