A/N: I do not own Harry Potter (although I wish that I did (money!! $_$)) all rights go to J.K Rowling, though I'm just borrowing her ideas and adding some of mine.

A Weasley overheard

At the end of the day, Harry, Draco, Crabbe, Goyle, Nott and Rowan threw themselves on the couches in the Slytherin common room.

'Tss..I guess we should do the homework' Draco said with a yawn.

'Probably the best' Nott said with a yawn of himself.

When they finished their homework, the Slytherins left for dinner in the great hall, after which they immediately returned to the common room, where Harry asked Rowan to practise spells with him.

To avoid commotion, the six people left for Harry's dormitory, at which they took they places at the far ends.

Rowan started.

'Tarantallegra' Rowan cried.

'Protego' said almost whispering. He effectively blocked Rowan's spell, and began to counter.

'Fumos' Harry said pointing his wand at the centre of the dormitory.

Smoke filled the dormitory, blocking everyone's sight.

Harry launched himself away from where his opponent had last spotted him and heard Rowan attempting a shield charm, while there was nothing to defend against.

When no one attempted any spells, Harry heard Rowan mutter.

'Ventus'

The smoke vanished making everybody visible again.

Harry noticed himself being ridiculously close to his opponent, and at the same time Rowan spotted Harry as well.

Fast as Harry was, his opponent was faster this time.

'Impedimenta' he cried victoriously.

With barely time to react Harry concentrated.

Levicorpus was the only spell Harry could do non verbal, and he was secretly very proud of it. His father said that it had been originally Snape's invention.

He felt himself being hoisted into the air by his ankle as he cast the spell upon himself. Just barely dodging the jinx Rowan send flying at him and making it bounce against the wall behind him..

Caught off guard by this sudden behaviour, Rowan didn't guard himself properly as Harry aimed for him.

'Expelliarmus' Harry cried.

The force of his spell send his opponent crashing wandless into to the dormitory wall.

Letting himself drop to the floor Harry moved to his unarmed opponent, who leaped at his wand.

'Incarcerous' Harry muttered.

Ropes magically appeared and began to wrap themselves around Rowan to prevent him from reaching his wand.

'This is over Rowan' Harry said.

Harry made the ropes vanish and used a summoning charm to retrieve the wand of his opponent, who took it with a grimace.

'Wow Harry, that was cool' Nott said from the doorway.

Crabbe and Goyle were also grunting in the doorway, but not in a language Harry could understand.

Draco moved towards him and clapped him on the back.

'Nice one Harry' He said grinning.

'Nice duel' Rowan said, flexing his arm where ropes had bound themselves especially tight.

'Should've had you with that impediment jinx..he muttered.'

'yeah that was a close one' Harry agreed.

Noticing that it was nearly eight o'clock, Harry made an excuse to Rowan and sped off towards the dungeons.

'Welcome Potter' Snape said after Harry closed the doors. 'As I said, in these lessons, I am going to teach you how to use spells more advanced for your current level.'

'I understand sir.' Harry said respectively.

'Good,' Snape said. 'The first spell that I'm going to try to teach you is an advanced version of a shield charm, the incantation is therefore longer, but the shield stronger. It is called the Protego Horribilis. It is an advanced defensive spell and therefore also one of Hogwarts many emergency protective enchantments. Say it after me….Protego Horribilis.'

'Protego Horribilis' Harry repeated.

Snape grimaced. 'That would be the easy part, now for the actual spell.'

Snape raised his wand and with what seemed like a slash of a sword moved his wand to create a shield of the brightest purple.

'Your turn Potter, lets see what you can do.'

Harry raised his wand, and clearly said 'Protego Horribilis'.

A tiny almost liquid substance appeared in front of Harry's wand. Snape tapped it with his wand, and it vanished into purple motes.

'Too tiny, and not solidified' Snape said as if he had not expected anything better. 'But no matter, no matter, I've seen people do worse on their first time attempting this spell.'

'It was pathetic..' Harry said frowning.

'And that is exactly why you are here now.' Snape said. 'Not meaning to discourage, but we are going to continue doing this for at least six months, maybe more.'

Harry gasped and asked the potion master why.

'The first stage is to produce the actual spell, after that we will quicken your wand movement for as much as I think to be possible, after that we will go non verbal until you can do this spell on instinct alone.. Now begin!'

At ten o'clock in the evening Harry left Snapes office. He was exhausted. For two hours he had attempted the shield charm, but only managed to make the liquid form slightly larger. He began to understand why Snape thought he needed six months to do this.

Growling the password, he stepped into the Slytherin common room. Entering his dormitory, he discovered everyone else already sound asleep. He sat on his bed and once more put his wand on his head.

'Demonstro'

The evening walks through the castle were now almost a routine for him. He had already discovered two hidden passageways that could come in handy if he would ever be late for class.

Moving from the dungeons into the entry hall, he spotted two figures running up the stairs.

Weasley and Granger.

As he floated nearer, he listened to their conversation.

'Do you really think the thieves who attempted to break into Gringotts were after whatever Hargid took from that vault?' Weasley asked.

'Yes, I'm sure of it. Remember that we saw Hagrid, that day on Diagon Alley, and your dad had a chat with him, and how Hagrid said that he just came from Gringotts, "secret Howarts business"?

"But that doesn't prove that he emptied the vault that was going to be burglarized' Weasley said frowning.

'Common Ron, the way he switched from subjects when you asked, and his face turning red? I'm 100% sure!'

Now that was interesting. Apparently, they had met Hagrid on the same day he did. He remembered seeing the giant man coming out of Gringotts.

Secret Hogwarts Business huh?

He remembered the conversation he caught at his first evening in Howarts.

'..Brought it from Gringotts Dumbledore' Hagrid whispered. Revealing a small reddish stone, and gave it to the headmaster.

'Thanks you Hagrid' the headmaster said equally whispering, and took the stone.

Could that reddish stone be the object that Hagrid had taken from Gringotts that very day, and that was attempted to be stolen that very day as well?

After returning to his body, he went to bed. He would need to discuss this with Draco and the others.
