By the end of break Harry was surprised at how the time went by he actually enjoyed his time. He got many gifts from James Sirius and Remus and none from Evangeline but he didn't get her one anyways. Or either of the Order members well except the small few. Close to the end Harry had beaten the two ex-Quidditch players three times over, and just had a blast. 

In the train back to Hogwarts Theo pulled out the book and flicked straight to the Cerberus page, they read over the page almost hungrily and Harry's eyes shone then passing it to Draco.

"Here," He breathed, pointing to the lines he was reading, "Cerberus' go straight to sleep when they are subjected to music."

"Brilliant, all we have to do is get through the rest of the tasks." Draco said excitedly, "I can play the violin,"

"That's lucky because Hogwarts would go nuts at hearing me play." Harry with with a grin, "We'll go as soon as possible."

They planned out when they would go and what they would need to take, neither of them had any idea who wanted the stone but that could come after they had it. 

Harry smirked with an Idea in his fathers quarters knowing both Sirius and James would be coming here before the feast, he set up a charm which would change their robes bright orange and green as soon as they left the portrait hole. Harry also charmed the couch to sing when sat on and left, hurrying down to join the rest of the students for the feast. Sirius and James rushed in at the last minute, throwing glares to the innocent faced first years as they moved to their places as the Head table. Once everyone had settled, the Headmaster rose with a grandfatherly smile on his face.

"Welcome back, I hope your Christmas' were wonderful; dig in." He announced and the feast began. The feast passed quickly, the trio spoke with their friends. 

"You know that you are going to be in for some arguments because of this." Draco muttered to him and Harry smirked.

"Oh I know, I can't wait to see his face." They left the hall but a voice stopped Harry in his tracks. 

"Harry James Potter." He winced. 

"The prank on my door?" James asked 

Harry then adopted the innocent look "I have no idea what you mean. Did you check if it was the other marauder?"

"What-er-oh never mind" He then stormed off confused at who did it. 

Harry yawned the next morning as he jabbed Draco and Theo awake, he had become more relaxed in his sleeping habits since his return to the future, not having the grueling training and lessons he put himself through anymore, but he wasn't worried as all his magic was regularly practiced. He had even made time to practice his bow and arrow work during the holidays, beginning to teach his father as the older raven hair was fascinated. Harry went down to wait in the common room reading a book as usual and Draco fell in to the room soon after followed by Theo, they trudged up to the Hall and absently ate breakfast. Their lessons were simple, both having read and studied ahead, and Harry was glad when the day was over. It was a calm day only to end by his wonderful sister after Transfiguration; it was always Transfiguration.

"Just because you think your as important as me doesn't make you any less pathetic." She spat at him and Harry merely raised an eyebrow. 

"Whatever you say, Evangeline," He drawled with a smirk.

"Well we were better without you, anyway." She huffed, flouncing off and leaving Harry frozen in the hall trying not to take it for word.

Out of the corner he saw he saw his father and Sirius come up the steps, laughing about something. His father looked so happy just with Sirius. As her words repeated through his head. James looked up and caught sight of Harry and knew something was off but when they reached him, Harry was already down the hall lost within Hogwarts. 

Harry found himself in the bottom of the dungeons in Salazar's Dueling room once again. With the rage of everything Evangelina threw at him through the year and always had a dream of a sibling. And now he has a twin at that, who just doesn't want him. He spent most the time that night in the room training his best and organizing his mind scape. It was far too long for him since he has done this. 

It was past night fall when Harry resurfaced, he ran into his two friends first. Draco obviously was right on trying and promising retribution for what she said and Theo swore it was not true at all. After Harry promised not to disappear again he headed up to his fathers quarters. He was beyond worried but with a long conversation Harry had an understanding with his sister and him. 

As days turned to weeks Harry came up with his own challenge, to make his own version of the Marauders map. Harry quizzed his father and uncle on the spells of the map because he was  going to add the shortcuts and everything he knew about the castle, he also had an idea on linking the map to viewing and listening spells which could be put on the portraits. Once he had a list of the spells he left to study the map, he was finished with his homework and Draco, Theo and Blaise was studying, the latest Herbology paper.

Harry sat on his bed, with his curtains drawn and Spero around his neck, and opened the map, scouring it for every detail that it had. He was amazed, there was so much there and the dots of people had Harry's mind automatically wondering what they were doing. Dumbledore seemed to be pacing in his office, Snape looked as if he was brewing and when Harry's eyes glanced on the Defence corridor on their way up to Padfoot and Prongs he froze. 

Quirinus Quirrell was stated clearly but nearly on top of him was the name 'Tom Marvolo Riddle', Harry frowned in confusion which only deepened when Quirrell moved and the name went with him, Harry had seen that name before and decided he would look in to it. He noted where he would add passageways, noting down the rooms he knew to be there but didn't seem to appear on the map, and how he could link the listening spells. He jotted down a few more notes before settling for sleep, Spero hissed her goodnight and curled up by his neck. It turned out he wasn't the only one who had heard the name Riddle, Draco pointed out an award the man had won in the 40's.

"Why did you want to know?" Harry shrugged and Draco rolled his eyes. 

"Well never mind that, guess what I have got my hands on." The blonde pulled out a violin from his trunk and Harry's eyes lit up. 

"Tonight?" Theo asked with a smirk.

"You read my mind." 

The trio were on edge all through dinner so much so that Harry completely blanked Evangeline, which, given the state of their current relationship was quite impressive. The trio went to bed early so they could catch a few hours, Harry told Spero to wake him when the moon was risen which was around half eleven, and when they rose they were alert and ready. The raven head cast his masking spell on him and Theo and told the blonde to cast the spell 'calor conspectu' at his temple.

"This is completely strange." He muttered prodding Harry, who just looked like a red/orange outline in the Slytherin dorms.

"Yeah it's a bit disconcerting."  Theo agreed with Draco.

"Come on you guys."

 They walked out and headed to the third floor, Harry was constantly checking the map but they were lucky. When they reached the Cerberus' room, Draco began to play the first thing that came to his mind, the blond was amazing and a beautiful tune floated through the room immediately sending the Cerberus to sleep. Harry levitated the paw of the trap door and Theo followed soon after him. Harry then yelled for the blond to come and, the music stopped and Draco came flying down behind him as the Cerberus growled, they landed on a plant that, started to wrap around their limbs. 

 "Devil snare." Theo hissed and Harry lit a fire to release them, he cancelled the masking spell as they got up.

"Not particularly difficult." Harry pointed out as they went down the corridor, they entered a room which had loads of flying keys, and Harry didn't even bother to fly on the broom to search for the right one. He placed his hand on the door and sent a pulse of magic through it, it clicked open and they walked in to a huge room.

"Is that a chess board?" Draco gasped and Harry nodded, when they tried to walk across the pieces came to life and blocked their way, Harry raised an eyebrow.

"I'm guessing we have to play our way across but I don't particularly want to play chess with stone pieces." Harry said to the pair who nodded in agreement.

"Any suggestions?"

Harry grinned and grabbed them by the arm, he flamed them to the other side if the white pieces, the blonde stumbled and started retching. "There, that works." Harry told them cheerfully, he received filthy looks. 

"What in Merlin's name was that?"

"And never do that again!" Harry merely smirked. 

"Come on, pull yourselves' together." Harry told them only for Draco to punch him and walk in to the next room; the blond immediately ran back out eyes wide.

"We don't have to go through that specific room do we?"

Harry raised his eyebrows and cautiously entered the room, he understood Theo's haste. A troll, around 20ft tall, stood with its club hanging dumbly at its side, it didn't notice them at first but when it did it gave a huge roar and swung its club, they dived out the way and Harry spotted the door on the opposite side.

"Dray, Theo the door is over there." Harry pointed dodging the club again. "Go through it and I'll flame."

The blond nodded and bolted, Harry flamed out just in time as the club smashed in to the floor where he had just been stood, they both bolted through the door and flames shot up in each doorway, ones were purple and one was black. Draco pointed out a sheet of parchment on the table which was filled with 7 different shaped and sized bottles, Harry picked it up and read it.

"Danger lies before you, while safety lies behind, Two of us will help you, whichever you would find. One among us seven will let you move ahead, Another will transport the drinker back instead. Two among our number hold only nettle wine, Three of us are killers, waiting hidden in line. Choose, unless you wish to stay here forevermore, To help you in this choice we give you these clues four: First, however slyly the poison tries to hide, You will always find some on nettle wine's left side; Second, different are those who stand at either end, But if you would move on wards, neither is your friend; Third, as you see clearly, all are different size, Neither dwarf nor giant holds death in their insides; Fourth, the second left and the second on the right, Are twins once you taste them, though different at first sight..."
