A/N: Hey, guys :D Ok, new chapter is up. It's Calliope's fourth year, Oliver's sixth and Harry's second and now it's the year where all hell breaks lose. I remember the first time I saw the "Chamber of Secrets", I wanted to go there and strangle all the Slytherins.

Bellamort500- Thanks a lot :D The name "Calliope" has its origins in the Greek mythology and means "good singer". I love that name too :)

xXMizz Alec VolturiXx- Thank you :D I'm sorry if Charlie won't appear anymore (since it's Callie's fourth year, he has gratuated from Hogwarts). But I will mention him often :)

Gotta Dance 88- Thank you so much :) Yes, Calliope will need all her bravery, especially with the events of "The Chamber of Secrets" and her being Muggle-born

Disclaimer: I don't own Harry Potter

The lake was bathed in the sunlight and the nature around was prospering. Many students were sitting at the shores, enjoying the perfect weather, without wanting to go inside and do homework.

Fred, George, Oliver and Calliope, each with a cup of pumpkin juice, were talking enthusiastically about Quidditch. From time to time, though, Oliver looked in secret towards the young girl and couldn't believe how much she had changed. Only the last year, Calliope was a plain third-year, but now she had blossomed into a very pretty teenager. Her light brown hair wasn't short anymore, but was falling right beneath her shoulders in soft waves and her impressive, violet eyes were sparkling.

'Oh, I love the lake so much' she said now sweetly. 'It's so beautiful, isn't it?'

'Yeah, yeah, we know water is basically your element' George laughed. 'I still remember second year, when you sneaked out of your dormitory…'

'…on a rainy night…' Fred continued with a dark voice.

'…and stayed outside until four o' clock in the morning…'

'…without even catching a cold'

'It wasn't only me' Calliope shrugged. 'My crazy roommate called Lexi Stone practically dragged me outside. We just wanted to do something fun and crazy'

'That's the spirit!' Oliver smiled.

'Of course, what else would you say?' George snapped at him. 'You must be crazy if you want us to practice at six o' clock in the morning'

'Six o' clock?' Calliope repeated, wondering how obsessed her best friend and the new captain of the Quidditch team could be. 'Come on, Oliver, don't you think that's a bit barbaric? I mean, no one can concentrate without a good night's sleep'

'Thanks a lot, Calliope' the twins said at the same time.

Then, they winked at each other and stood up at the same time. The others weren't surprised. After three years of close friendship, they had realized that Fred and George were always spontaneous, always with new ideas for pranks and never afraid of the consequences. Even though, Calliope would be very grateful to them if they would stop making implies that she had a crush on Oliver. Oliver was a combination of best friend and brother for her and nothing more.

'Where are you going?' Oliver asked curiously.

'Oh, we want to find Lee' they answered. 'He said something about putting a Niffler in Snape's room'

After they left, a comfortable silence fell between Oliver and Calliope for a few minutes, until it was the Keeper who broke it by taking a book out of his bag.

'Here' he handed it to his friend. 'I thought you wanted to read it, right?'

'Quidditch Through the Ages' Calliope read the title and smiled widely. 'Thanks a lot, Ollie!'

Oliver rubbed his neck at the sound of his nickname coming from her and his face became slightly redder. Calliope couldn't believe it. Oliver Wood, the mighty Quidditch-obsessed Captain of the Gryffindor team, was actually blushing…and it suited him.

What? she slapped herself mentally. Why in the name of Godric Gryffindor did I think that?

'Don't mention it' Oliver made a gesture that it wasn't anything important. 'As you see, I keep my promises'

'Of course you do' Calliope gave him a warm smile. 'You're an excellent Keeper, after all'

Oliver returned the smile, but his look became more melancholic. Calliope, who could read him like an open book, understood at once what he was thinking about.

'Oliver, don't worry. You'll win the Cup. You're a very good player and captain, one of the best. You have a skilled team and, seriously, Harry Potter is as talented as Charlie was'

Oliver nodded and looked better. Last year, when Calliope learned that the famous Harry Potter had become the new Gryffindor Seeker only in his first year, she couldn't believe it and was very curious to see how he would fly. The result didn't disappoint her. Harry was riding his broom as if he was flying since he was born and everybody agreed on that. Being close friends with Oliver, Calliope had met him and was surprised by his kindness, his courage and his modesty. Being so famous didn't affect him at all, on the contrary, it was embarrassing him.

'So, where are Angelina, Alicia and Katie?' she asked now, referring to the three Chasers, with whom she was getting along very well.

'Probably discussing some girl stuff I will never understand' Oliver smiled. 'Lexi and the others?'

'Lexi, Phoebe and Elaine are with Yvonne and Linda from Hufflepuff' Calliope answered. 'And I bet all my chocolate frog cards that Harriet is with that Ravenclaw, Matthew. She had a crush on him since first year, so you can understand how she feels now that she's dating him'

Oliver chuckled and nodded again. He didn't know very much about the others, but he had talked to Lexi, who seemed to be Calliope's best female friend. He wanted to ask something else, but then an evil voice interrupted them.

'Wood. As I see, your friendships didn't change at all'

Marcus Flint had approached them. Calliope's eyes narrowed. The memory of him bullying her and her attacking him was still fresh in her mind. She had a difficult time in detention with Snape afterwards, but it was still her personal triumph. Since then, the only one who was despising the Slytherin Chaser more than her, was no other than Oliver himself.

'What do you mean, Flint?' Oliver didn't try to hide the hatred and anger he was feeling towards him.

'I had thought that, now that you're a Captain, you would hang out with…much better people' Flint grinned and looked straight at Calliope, who glared bravely back at him.

'Get lost, Flint!' she hissed. 'It's not your business with whom he hangs out or…'

'It's okay, Callie' Oliver told her softly. 'It's fine, he knows you're my best friend'

'Nice best friends you have, Wood' Flint didn't lose his smile. 'I had expected something more…not a Mudblood'

Since she learned that some wizards, especially the Slytherins, were despising Muggle-borns, Calliope was waiting to be insulted by them. Yet, this word, the worst someone could ever say to her, was a shock that overwhelmed her like a huge wave. It would be better if Flint had punched her or attacked her with some sort of spell. She wanted to speak, but her wet eyes and her trembling voice prevented her and she just looked at the lake, trying to control her breath.

A gasp made her turn again. Oliver had stood up and packed Flint from his shirt, with a furious expression on his face. Calliope had never seen him so furious before.

'Don't ever say something like this again, got it?' he yelled at the captain of the Slytherin Quidditch team. 'For your information, you filthy Slytherin, Calliope is much purer than you could ever be!'

Flint threw an ironic look towards her and left. Oliver immediately sat next to her and put his arm protectively around her shoulder. Calliope, ashamed for her tears, wanted to wipe them away, but Oliver held her hand.

'I'm sorry' she whispered.

'You're sorry?' Oliver couldn't believe his ears. 'He insulted you and you say you're sorry?'

'I'm sorry for crying, for not doing anything…'

'Calliope' her friend took a deep breath to calm down 'that word is the most insulting word against a Muggle-born. I had heard it before and was frustrated. Your reaction was normal. But do you want to learn something?'

She raised her head and looked at him confused. Her expression, broken and vulnerable, hurt him. He couldn't see her like this.

'You are a thousand times better that him. And I mean it, Calliope! Being Muggle-born or…"pureblood"' he shuddered, feeling disgusted by this word 'has nothing to do with who you are and what you do in your life. Trust me!'

A smile of gratitude appeared on her face and Calliope felt lucky that she had such a good friend, who didn't care about her origins. She rested her head on his shoulder and he rubbed her arm.

'That's much better' he whispered, happy that he had managed to comfort her and make her smile. 'Don't give a damn about what other people say. I don't want to see tears in those beautiful eyes again'

Calliope smiled wider. She wanted to thank him for everything, but she knew that words weren't necessary. He would understand, as always. When she was with him, she was feeling herself.

'Oh, look at them, Freddie!' George made them gasp. 'Now they're all lovey-dovey. About time, don't you think?'

'Certainly, bro' Fred agreed as they were sitting down next to them.

'Can you two be serious, at least for once?' Oliver said angrily. 'Not everything is a joke, guys!'

What happened?' the twins asked, noticing Calliope's tear-stained face.

'Oliver, please, don't…' Calliope mumbled, not wanting to worry her friends.

'Marcus Flint, that son of a Death Eater, again!' Oliver ignored her. 'He called her…He called her…He called her you-know-what'

'WHAT?' they yelled, balling their hands into fists.

'You're kidding, aren't you?'

'Yeah, guys, Calliope is crying because I'm kidding' Oliver rolled his eyes. 'Anyway, I told him that Calliope is purer than him'

'Anyone is purer…'

'…than the snakes'

'I was prepared for that' Calliope spoke. 'Since you guys warned me that Slytherins consider Muggle-borns scum, I was waiting some sort of insult towards me. But this word…Even the sound of it is horrible'

'It's all a matter of principles' George explained. 'Some families claim that they were magical from the beginning and therefore think that they're better than the rest of us'

'Which is rubbish' Fred nodded. 'Look at Callie or at Ron's friend, Hermione Granger. They're Muggle-born, but they're both wonderful witches'

Calliope smiled again and removed her head from Oliver's shoulder, feeling much better. She knew her friends were right and she wasn't ashamed for having non-magical parents. She loved them with all her heart and they had raised her and given her all their love. She was proud of them for who they were.

'I should send Bludger after him' Oliver muttered.

'And how would you sneak in Madam Hooch's office to steal it, Ollie?' Calliope teased him.

'Not the ball' Oliver laughed. 'My new owl. I named her Bludger and she would bite Flint until he would beg for mercy'

Calliope and the Weasley twins burst into laughter. Oliver was Oliver and would never change. If he wouldn't name his owl Bludger, he would name her Quaffle or Snitch.

'Well, you've found your laughter again' George commented relieved.

'Of course' she nodded. 'I mean, I know that you guys are right and I surely won't let Flint ruin my mood'

A/N: So, my friends, that was it. Hoe you enjoyed it. Calliope seems to have calmed down after Flint's insults, but what will happen when an even bigger threat appears? Can't wait for your reviews :D xx
