Chapter 2: Surprises a plenty

July 31, 2003

Harry was lying in the hammock he had set up in Zeus's cabin having moved out Hear's cabin when he nine. As he lay there he thought of his half-sister Thalia Grace who was half dead half alive because someone had sent some of his uncles most dangerous creatures after her. While most might think that Harry and his father might hate Lord Hades for the attack. But neither of them did because they knew that Hades did not send those creatures. Harry came to the defense of Hades believing that even if it had been creatures were from the Underworld, it could have been someone else because the Underworld is large place and there are quite a few enemies of the gods down there with a lot of power. Zeus thought about it then told Hades that he was off the hook for now.

A knock on the door broke Harry out of his thoughts, when he opened the door he saw Luke Castellan Son of Hermes standing at the door. "Harry Chiron wants to see you." Luke said with a smirk.

Harry shook his head and head out of the cabin. As he and Luke walked through camp they saw and of campers, nymphs, or satyrs around the camp. They wished him a happy birthday as he went by, and he told them thank you. Luke was leading him towards the Dinning Pavilion, for what Harry had no idea but he wondered if it had something to do with the lack of people around the camp. When they got to the Dinning Pavilion a few of Harry's friends shouted surprise as he entered. Harry smiled and thanked them as he walked over to his uncle Sirius, he asked Sirius, "Where are mom and Mooney?"

"Your mom should be back soon, but Mooney is looking after a group of Hunters." Sirius said sighing.

"Lord Apollo?" Harry asked already knowing the answer. Sirius gave him the who else look. "I wonder if he will ever give up on the Hunters?" Harry asked as he facepalmed at the antics of Apollo.

"Harry Sirius?" a booming voice asked startling the campers.

"Hagrid what are you doing here and how did you get through the barrier?" Sirius asked in a shocked tone.

"Sirius do not worry the barrier is still strong as ever. Albus alerted me that Hagrid would be coming to pick up Harry to get his school supplies for Hogwarts." Chiron explained calmly.

"But me and Lily were going to take him shopping." Sirius said in a upset tone.

"Sirius, you and Lily can still come." Hagrid said happily.

"Good because you wouldn't be able to stop me." Lily said walking into the Dinning Pavilion. Lily gave Harry and a girl a hug and tried to give a hug to Luke by he started running.

"Lily it is so good to see you." Hagrid said as years started appear. "I miss James he was such a nice kid." Hagrid said as he started sobbing.

"Don't worry Hagrid; James would be happy that you are helping Harry get his stuff for Hogwarts." Lily said trying to calm down the gentle half giant. They ate their food and head towards a safe place for them transport them to Diagon Alley.

=== BREAK ===

As the group's feet touched the ground again they noticed that they were in one of the portkey areas that would allow them access to the Leaky Cauldron and Diagon Alley. As they walked through the Leaky Cauldron, some of the customers recognized Lily and Sirius and wanted to congratulate them on the defeat of You-Know-Who. After everyone had shaken their hands at least twice Hagrid helped them move out of the Leaky Cauldron and into the alley. Hagrid tapped three bricks which turned into an archway leading to Diagon Alley. "Welcome to Diagon Alley." Hagrid said with a smile.

Harry was looking around wildly trying to take everything in at once. "So where are we going to first?" Harry asked curiously.

"Gringotts we need to get money for your school supplies." Lily explained as a twinge of pain ran through her heart.

"You wish James was here don't you Lily?" Hagrid asked as he placed his hand gently on Lily shoulder. Lily started tearing up remembering all the plans that they had made when James heard about Harry. James was so happy to be a father to Harry, even if Harry was not his son he was still happy. Hagrid squeezed Lily lightly and said, "We will all miss James but remember he will always be with you."

"Thank you Hagrid." Lily said giving him a small smile. When she recomposed herself they went off to Gringotts.

As they entered Gringotts Harry read an engraving on the doors that read.

Enter, stranger, but take heed

Of what awaits the sin of greed

For those who take, but do not earn,

Must pay most dearly in their turn.

So if you seek beneath our floors

A treasure that was never yours,

Thief, you have been warned, beware

Of finding more than treasure there.

This caused Harry to smirk and wonder if Lord Hermes or any of his children could get away with stealing from here. As if reading his mind Lily whispered to him, "Don't even think of challenging Lord Hermes or any of his children." Sirius barked with laughter, which caused Lily to stare at him sternly. Sirius wet with Hagrid to do something, while Lily and Harry searched for a teller.

When they got to one of the teller Lily saw who tell was. She then said in a respectful tone, "Hello Griphook it is good to see you again."

Griphook looked up in surprise that a witch or wizard would remember a goblins name. When he saw who it was a small smile appeared on his face then quickly disappeared. "What my Gringotts assist you with today?" Griphook asked flatly.

"I would like to withdraw some money from the Potter vault, for school supplies." Lily said kindly to Griphook.

Griphook nodded and motioned for a goblin to take his spy until he returns. As Griphook lead them through the bank and towards the carts he told Lily that the day James passed away they also sent offerings to Hades for James safe passage to Elysium. This caused Lily to give Griphook a quick hug and tell him thank you. After both had finished with Gringotts they met back up outside with Sirius and Hagrid who looked a little green. He excused himself to the Leaky Cauldron where said he would wait for them.

"Alright where is our first stop?" Sirius asked curiously.

"I think we should get robes and clothes first." Lily said with a small smile. Both Harry and Sirius sighed and lowered their heads but fallowed her.

The first place they went to was Madam Malkin's Robes for All Occasions. When they entered a girl at the counter asked without looking if they were here for Hogwarts, when they said yes she motioned them into the back. When walked into the back they saw a blond haired boy getting his robes.

"Hello dear starting Hogwarts too?" a lady asked kindly.

"Yes ma'am." Harry said kindly and respectfully. The lady motioned for him to stand next to the boy.

"So you continue to associate yourself with low lives and filth Black. Your poor family is rolling over in their graves." a man said from the waiting area.

"At least I not someone's boot licking lackey." Sirius retorted with a smirk.

"My father is no one's lackey!" the blond boy shouted angrily.

"Yes he is." Lily said out loud.

"What would a mudblood like you know." the man said angrily.

The woman who was working on the boy stopped pinning and stood up. She angrily said, "I will not have that kind of language in my store get out."

"We will do no such thing, and if you know what is good for you and your business you will finish it for free." the man said threateningly.

"I do not care who you pay of within the ministry I will not tolerate -" the woman started to say.

As the man and reached for his wand Harry moved quickly towards the boy. "I would put your wand away unless you to lose your son." Harry said in a cold tone. What all the adults saw was both of Harry's around the boys neck, ready to snap the boys neck.

"You wouldn't dare." the man said threateningly.

Harry's arms started to twist the boy's neck when someone shouted, "Enough!" A woman walked into the store and look between Harry and her husband. "What did you do?" the woman asked angrily.

"Nothing your cousin brought in this mudblood, then this woman decided she was better than us." the man said making up a story.

"I highly doubt that Lucius. You think that you can threaten people and always get away with it. You never think that just maybe someone out there is stronger than you. Now I find our son in danger and you are challenging someone who you cannot scare. Do you realize that he could have killed our son." the woman said angrily.

"Then I would have had the Dementors suck out his and his mudblood mother worthless souls." Lucius said confidently. Outside a storm started to brew and grow.

"Malfoy for once in your miserable life learn to watch what you say." Sirius said clamping his hand over Lucius mouth after he heard the first crackles of thunder.

"I am tired of this. Draco you have a choice you either stay with me your mother or your stepfather." Draco's mom said dropping a bomb shell.

"What he isn't my dad?" Draco asked angrily.

"Of course he isn't why would I let someone like him touch me, your stepfather would sleep with anything that had two legs." Draco's mother said with hate in her voice. She then said happily, "Your father is a powerful man that travels around a lot, but he cared for you. You see there were times when he would send me something; he told me that it would help protect you from monsters."

The group thought about it for a few seconds and put the pieces together about the identity of Draco's father. Lily walked over to Draco's mother and whispered something into her ear, when she nodded Lily told Harry to let go. She then said that they would be taking Draco someplace safe for the rest of the summer. After Lucius had been thrown out of the store they went about finishing getting the robes ready fitted and purchasing said robes. They head to the other stores on the list, when they came out there were only two stores left to visit one being for an animal companion and a wand.

The first stop was Eeylops Owl Emporium where they looked around at the different animals. Both boys walked around until something stopped them. The cause of them stopping was an owl landing on each of the boys and calmed them as their humans. For Harry a Snow White owl started to rub her head against his. For Draco a strong and regal eagle owl stood proudly on his shoulder, this caused Draco feel stronger than he had been feeling. They then paid and left with their companions and headed to their last shop.

When they walked in Harry heard a bell in the back ring. Harry also felt the magic in the building pulse and was enjoying it when an old man came sliding into the front of the store. "Ah Mr. Potter and Mr. Malfoy I wondered when I would see you both." the man said with a smile. He then looked at the three adults and said, "I hope the three have been taking, care your wands." The three adults nodded their heads which caused the man smile a little. "Good so let's get these two demigods their wep - I mean wands." the man said with a smile. The man head back towards the back of the store where door stood and unlocked it. When he went through the door two boxes glowed blue, he pulled these boxes and walked back out the door and locked it up. He then walked back to the front and put on a pair of glasses and looked at the boxes then the boys. What the man saw was different lines leaving the boxes and attaching themselves to the either boy. "Here you go boys take good care of these two they might save your life one day. Also inside is a note to read when you get back to camp. Also Lily will you tell Chiron I said hi." the man said with a smile.

The group walked to the Leaky Cauldron to meet up with Hagrid who would give the portkey back to the forest outside of camp. Sirius diced to stay with Draco's mom to help her divorce Lucius and help get settled into someplace safe.

=== BREAK ===

Back at camp Harry showed Draco around the camp while his mom explained the situation with Chiron.

"So Draco are you ready to meet Chiron and Mr. D?" Harry asked saying Mr. D with a sigh. Draco was nervous but nodded and they headed up to the Big House. When they got to the Big House Harry introduced Draco to Chiron and Mr. D who just grunted. "Don't worry about Mr. D he doesn't like us Demigods." Harry told Draco with a sigh.

"Well I believe that Hermes Cabin has a bunk -" Chiron started say when a symbol appeared over Draco's head.

"Well Draco I feel sorry for you." Harry said with pity

"Why?" Draco asked curiously.

"Because all your brothers and sisters like to do is making things." Harry said rolling his eyes.

"I don't have a problem with that." Draco said not understanding the problem.

"Harry will you show Draco to Hephaestus's cabin, I believe that's where Charles is." Chiron said questioningly. Harry nodded and lead Draco away from the big house. When they were both gone Chiron asked, "Do you still think something is wrong with the young man?"

"Only time will tell if he is the serpent that the Oracle spoke of." Lily said as she watched Harry and Draco walk away.

A/N: Were you surprised by who Draco's father is, I hope so. Sorry about the shortness of the chapter and how it was a bit boring, but do not fear the next chapter is the train ride and old family hatreds die hard. Also what was is this about a serpent and what did the Oracle tell Lily. And as always please read and review.
