Chapter 4: The Task

December will approach in two weeks' time, most of the students in Hogwarts had decided of where they are going to spend for their upcoming Christmas. Spencer had received a letter from his parents saying that this time around Spencer and his younger siblings are required to go back home for Christmas in Italy since their grandparents had decided to celebrates Christmas there as well. And in the letter also indicated that his Uncle Tsuna and the whole of the Vongola 10th family, and includes the Varia will come to the Cavallone mansion to celebrates Christmas and Boxing day as well. Seems that their father is planning to have a big Christmas party this time around, and Spencer hasn't told anyone about it yet except the twins.

Since the winter season is approaching pretty soon, most students already spent most of their time inside the school and even though it is not snowing yet, the weather was pretty cold it could turn hot water to a cold one in no time.

It was on Monday morning that the students in Hogwarts received shocking and maybe good news as few students from different schools from around the world will come to Hogwarts for a friendly visit and rumours has it that these students will stays in Hogwarts before Christmas break. These students will arrived starting today and the schools that participates are Beauxbatons Academy of Magic, Durmstrang Institute, Salem Witches Institute and Brazilian Wizarding School and of course Hogwarts. Hogwarts had been chosen since it was located in the middle between Europe and the America continents.

As the students were pretty excited to hear about it, there were noises coming from outside the school as Filch came running into the Great Hall, announcing that some of the school participates had just arrived.

Hearing it, the students started running outside the Great Hall to 'greets' their guests as their Headmistress and most of the teachers in Hogwarts joining them in the school ground.

"Fratello, I can't see, Vince, stop pushing," Ariella spoke as she grabbed her elder brother's robe, afraid that she might fall since as Spencer quickly grabbed their hands, making sure that they didn't fall or being pushed by others and some of the girls who watched them was hoping that it is their hands he was holding. The twins each grab Lily and Christen's hands and pull the two girls together so that the four of them didn't get separated as students begin to fill the school ground.

The first school to arrive is Durmstrang as their ship emerged from below the lake. Then, they were followed by the Brazilian school as they arrived by some sort of magical transports on the road. The students' cheers as they welcomed their guests when some of them gasped to see flying horses pulling a pastel blue coach in the sky approaching Hogwarts, the Beauxbatons had arrived and they were followed by the Salem Witches Institution students that ride in a red and black coach pulled by some flying broomsticks as the 'head driver' pulled his broomstick towards the school ground as the Headmistress Professor McGonagall gave a warm welcome to each of them.

The Great Hall was filled with students as each of the four houses will be joined by the students from other schools. Students from Durmstrang sat on the Slytherin table, Beauxbatons on the Ravenclaw, and Salem joined the Gryffindor table and the Brazilian on Hufflepuff. Noises filled the Great Hall as students and teachers engaged in conversation among one another. One of the teachers from Durmstrang happened to be Viktor Krum, and most of the Gryffindor students, namely the Weasley and the Potter clans and few others, hated him, and especially Spencer since he had found out that he used to call his mother Mudblood when she was a student in Hogwarts but he didn't want to shows his hatred on him pretty obvious in front of the others, and especially not in front of his younger siblings.

"What is that git doing here, and why the Durmstrang had to send him instead of other teacher to be part of this friendly visit?" James spoke quietly among them as they eyed Viktor Krum in hatred, and even Neville shows his discomfort to be around him. From his eyes he could see the glares Spencer sent to the Durmstrang's professor, and he knew how much his best friend loathe him as he never see this side of him before.

"Hey mate, are you alright?" James asked the handsome blonde as he snapped from his gazed and turned to him.

"Yea, no I'm alright," Spencer started, tries to act normally but somehow couldn't convince his best friends.

"It's alright mate, we understand it pretty well," Edward replied, his gazed turned to the front as their headmistress is about to give her speech.

"Your attention please," the Headmistress spoke as silent begins to take over the noisy hall students and teachers turned their attention to the Hogwarts Headmistress whom about to start giving out her speech.

"Thank you. First of all I would like to welcome our friends from four different schools to Hogwarts and thank you for taking part in this friendly visit to our beloved school, please give them a big applause," she spoke as the students gives their big claps and some even whistled around. Spencer and the gang smiled as they clapped their hands and some even cheered loudly.

"And as you can see, the four schools had been divided to sits in these four houses, and I have chosen a representative from each house to become their tour guide while they are here, and we, the teachers in Hogwarts, had been decided to choose one best students from each house to become the representative. Our decision is final, and I want each of these representatives to be at their best and I also hope that every student from each house will give their cooperation as well when it is needed."

By this time, almost all the Hogwarts students paled and started looking at each other, wondering who the lucky person among them while some other are pretty confident and hoping to be the one to be chosen to represents their house. At first, Spencer and the almost the whole gang looked at Victoire since she's the eldest among them and she is even one of the bright students as well, but somehow she turned to him, knowing that he is the brightest and by far the bravest among the Gryffindor students. She smiled at him and Spencer flinched, he didn't like the idea when she smiled at him in a way at this very moment. He mouthed "impossible" to her as he shook his head and pointed his finger at her to indicate that she will be the one to be chosen while Victoire smirked teasingly at him.

I will call the name of the students that will represents their house, and when I call your name, please stand up so that the guests' of your house will recognize you and it is convenience for them if they have any particular needs during their visit here."

By that time, the guests of each house clapped their hands happily while most of the Hogwarts students begins to sulking, praying that it isn't their name that will be call out.

"For Slytherin house, Mr Scorpius Malfoy."

Scorpius flinched at first but when the Slytherin clapped their hands and cheered loudly, he stood, quite hesitate at first then some of the Durmstrang shakes hands with him while his sister cheered happily for him.

Spencer knows that Scorpius was a very confident and clever student and one of his competitors when it comes to study. He smiled at him as he showing him a thumb up.

"For Hufflepuff house, Ms Geraldine Henderson."

Another cheers coming from the Hufflepuff table as the sixth year student stood up while most of the students from both Ravenclaw and Gryffindor, especially the senior students, still waiting anxiously as some of them could feel their heart skipped a beat.

"For Ravenclaw house, Ms Janella Olbert."

Spencer glanced at the seventh year student as she stood, she is one of the most promising Ravenclaw's Quidditch chasers and she is a nice and friendly student as well who never fail to help anyone in need when it comes to study.

By that time, most of the senior students in Gryffindor table looked at each other as they are the remaining table that their Headmistress hasn't calls yet. Spencer and Victoire still smirked and pointed at each other as their beloved Headmistress is about to announce the name of the Gryffindor's representative.

"For Gryffindor house, Mr Spencer Cavallone."

Spencer flinched as his eyes wide opened and Victoire clapped and cheered the loudest among all of them as he stood up and tries to smile but by right he could feel some sort of discomfort in his stomach as if hundreds of butterflies roamed around and doing summersault inside. Some of their guests stood up and shakes hands with him and congratulates him. When he stood, he could see some of the girls' students looked at him in awe and that adding more to his discomfort.

"Congratulation fratello, we are so proud of you," the twins spoke simultaneously, smiling as they clapped with hands loudly with the others. Spencer smiled as he nods his head at their Headmistress and somehow tries to restrain himself from glaring at one of the Durmstrang's professor.

"That was very tiring, man I need more rest," Trevor whined as they reached the Gryffindor Common Room. He slumped himself on the sofa, followed by Johnny and Howard as Spencer, James and Edward looked sit on the floor. Most of the Gryffindor students had left to their own dormitory except a few of them who are still at the Common Room. Spencer looked at his watch, clearly it is quite late and he had lots to do. Today there were greet-and-meet session with their guests, the students from Salem and as the representative of Gryffindor it is his duty to introduce the Gryffindor students to their guests. Then after the feast, he and the Head of Gryffindor House had to escort their guests back to the guestrooms and they had to make some temporary timetable so that he can divided his time since he is not only a representative but also a Prefect and he still got classes to attend.

Listened to Trevor whined nonstop makes him and the rest of them glared at the Gryffindor prankster. Realized that they're stared at him, Trevor stopped his whining and winced as he tried to smile at them.

Standing on his feet, Spencer wished them goodnight before going to his dormitory which he shared with the rest of the fifth year boy students.

After taking a nice, warm shower, he changed into his dark blue flannel pajamas and lied down on his bed and as soon as his head hit the pillow he fell into a dreamless slumber.

The next morning, Spencer woke up a little bit earlier than usual. After having his shower and wore his school uniform, he left the Gryffindor tower towards the guestrooms to greet their guest of house. As he arrived there, the Head of Gryffindor House, Neville was already there, talking to one of the professor from Salem.

"Good morning, Professor Longbottom, and good morning to you sir, Professor Adelthorn," Spencer greeted the two professors as they greeted him back.

"Good morning Mr Cavallone, you're quite early today," Neville spoke as he smiled at the young Gryffindor, Spencer was one of his top students in his class and he was very proud of his old friend's son's achievement which could rival his own mother.

"Just called me Spencer, sir," Spencer said as he could see the students from Salem are now coming from their rooms with another professor, a female professor.

"Good morning Professor Ruskan," Spencer greeted the female professor as she nodded her head and smiled at him.

As everyone is ready for the day, Spencer led them to the Great Hall for breakfast, and on the way there he stumbled upon Scorpius who also led his House's guests to the Great Hall. He could see the Durmstrang's professor, Viktor Krum is walking in front of them as he was busy talking to Professor Slughorn, one of the oldest professor in Hogwarts. Spencer tries not to stare at Viktor Krum and turned his gaze somewhere else as Scorpius nudged his elbow with his.

"Morning mate," greeted the Slytherin student.

"Morning," replied the future Cavallone boss.

"So, are you ready to this new task?" asked Scorpius as they approaches the Great Hall, the two of them leads their guests to their respective tables as foods and drinks are filling the tables and the two of them could see that the guests on Hufflepuff and Ravenclaw are already there as well.

"Can say, just a bit nervous, actually," responded the handsome blonde as they both went separately and sit on their own table along with their guests while the teachers went to their own table.

"So, I hope that all of you had a pleasant night yesterday," Spencer said to one of the student from Salem who apparently is the senior student among them and she nodded her head and smiled at him.

"We have a pleasant night yesterday, and some good sleep as well, thanks for asking," she responded with a smile, and Spencer remembered that the other students from Salem Witches Institution called her as Josephine Delton, the senior and a prefect from Salem, and from his view Spencer could tell that this Josephine girl is an intelligent person.

"It's great to know, if there's any question or requirement please do not hesitate to ask, me and along with my friends will try to aid you as much as possible as we could, so hope you guys enjoys your breakfast," he replied and a smile stuck in his face, which makes some of the students, well apparently all of them are witches, to blushes and giggles among themselves.

"Thank you, we are eager to find out," she said nonchalantly and a smile appeared in her beautiful face.

The whole of them proceed into eating their breakfast when one by one the Hogwarts students begins to fill the Great Hall to have their breakfast before proceeds into their respective classes.

First day gone by and Spencer was fully worn out, his first duty was to showed their guests around Hogwarts, and so far they have covered almost one third of the school area. Luckily he got his best friends to tagged along with him and they had helped him to explain some about their school and its history and such.

And luckily on that night he wasn't on his prefect duty so he took the time to rest and read a letter that he got earlier from his parents. Looking out into the dark sky outside from his dormitory window he was about to read the letter when there's a knock on the door. James got up from his bed and opened the door only to see Vincent, Ariella and Lily in their pajamas stood outside their dormitory and in Ariella's arm was her black cat, Mystic. The cat purred as she strokes its fur softly.

"These three are hardly be separated these days, and Lily was never this close to anyone before, not even to us or to our cousins," James thought to himself as he allowed the first year trio to entered into their dormitory as both the twins ran towards their elder brother while Lily followed them from behind and sits next to Ariella who sits on Spencer's bed as Ariella put Mystic on the bed. Mystic jumped from the bed and into Spencer's lap, snuggles itself into the warm of Spencer's arm as he strokes the cat's fur softly.

"Lily, your brother is here, not there," teased James as Lily looked at him and her mouth pouted. James couldn't help but giggles as he just loved teasing his beloved youngest sister and knew how close she is to the twins, her real best friends that are not her cousins.

"Too bad James, I've got your sister's attention better than you," Spencer couldn't helped but to teased his best friend as James tossed his pillow at his best friend which he managed to caught gracefully before the pillow hit his face and tossed it back to James which hit him right in the face. The two of them then laughed as Edward came back from his shower and spotted the first year trio.

"Hello kids, not sleepy yet?" he asked as the three of them shook their heads.

"Not quite, we came to talk to fratello," Vincent replied smilingly as he sits next to Spencer and looked at the letter in his hand, the letter from their parents, he guesses.

Edward looked at them as he used to hear them called him fratello instead of using his name, showing that they're respected their elder brother very much even though he quite often saw them teased him. The twins were unlike any of the Weasleys or the Potters where they're often called each other by names, even if they were the youngest in the family; seem that their family concepts are way different from one another.

Edward was meant to asked Spencer about the presence of Viktor Krum in Hogwarts but he hold to it since Spencer's younger siblings were around at the moment and he's not sure whether the twins knew about it or not, but he prefer to play it safe and keep it shut, waiting for them to leave before ask.

Looking at the handsome blonde interacted and giggled happily with his younger siblings and Lily, Edward could see from the glints of Spencer's eyes that it were filled with love and happiness, something that he never saw before. Turned his gaze towards his cousin who listened attentively to their little conversation he could see that James was pretty amused as his own sister joined into the Cavallone's conversation and seems that they didn't mind at all.

xoxoxo

Ariella and Lily decided to go to bed as they are now pretty tired and Ariella yawned as she picked up Mystic from her brother's arm. Spencer hugged and kissed her forehead as they wished each other goodnight and he then hugged Lily and ruffled her hair as the girl let out a giggle. James and the rest of the fifth year boys watched them in amused to see how Spencer treated Lily liked his own sister and more surprisingly for James as a tint of jealousy appeared in his heart as his own little sister could easily fall for Spencer's brotherly love.

"Hey Lily, don't want to give your big brother a goodnight hug?" James teased as a smile curved on his lips. Lily walked towards him and hugged him before the two girls left the dormitory and returns to their own dormitory.

Vincent on the other hand, stayed behind as he wanted to speak with his elder brother. He waited for the girl to leave, especially Lily since he and his twin had some things in their mind.

"Okay young man, why don't you go to your dormitory as well, got something to tell?" Spencer asked him as he was a bit hesitated at first, seeing that the other fifth year boys stared at them with interest.

"Well, I've got something to tell you, but it's quite…well how to say it," Vincent spoke as he's trying to find the suitable word to say as he scratched his temple. Spencer nodded understandingly as he pulled his brother to his bed and pulled the curtain around his bed and before proceeds into their brotherly conversation he warned his friends not trying to peek on them as they nodded their heads, getting his message clearly. He then put the silencing charm so that they could talk easily.

"Okay, now no one could hear us, so you can tell me what is it that bothered you?" Spencer asked his younger brother as he fiddling with his fingers.

"Well, you know that Christmas is coming soon right, and we need to go back to Italy to celebrate. So Ari and I are thinking of giving Lily and Christen some Christmas present before leaving and somehow we already knew of what we wanted to give them, but we don't know how to tell mama and papa about it. So we think that maybe you could help us, and we don't want Lily and Christen to know since this is our secret, we wants to surprise them, so can you please?" Vincent slowly spilled to his brother of what are playing in his mind as Spencer grinned as he listened to his brother talked.

"So, this is what you want to talked about. Sure little brother no problem with that, but what do you mean that the two of you didn't know how to tell mama and papa about it. I'm sure that mama and papa will understand, besides it is for Christmas presents, so I don't think mama and papa will think badly of it," Spencer replied as he pulled his knees to his chest and wrapped his arms around it.

"We know, just that we don't know how to describe it pretty well, we wants it to be meaningful for them, just liked how mama and papa often gave us gifts that comes with certain meaning, we wanted it to be the same exact, a good and meaningful present for them, and between all of us you are very clear of it if you know what I meant," Vincent responded as Spencer listened thoughtfully, knowing of what his brother meant.

"Okay, so what kind of message that both of you wished in their present?"

"Well, we are hoping for the friendships appreciation or something like that, we wanted them to know how we appreciate their friendship with us, and the message had to be, you know, beautiful and meaningful."

"Okay, I think I get it. No problem at all, so what kind of presents that both of you wished to give to them?" Spencer spoke as he flashed a smile in his face.

"Well…" Vincent proceeds to tell his brother of what he and his twin have been planned to get for their friends for Christmas.
