Unexpected quest number 6(would expected Percy to stay out of this one, though)

The Athena(not) brat

We landed in front of a tub with a a sign that says "The Leaky Cauldron". Annabeth said: " Here it says we should ask for Butterbeer, go to the back and tap a certain brick." Leo replied: " Here I am, thinking Hecate gave you a tourist pamphlet." We erupted in laughter, except Zia, who walked to Annabeth and jabbed her finger at the bar, saying with suspicion: "How come I have a feeling we're the only one who can see the bar?" 

She's right, but not completely. A giant and a boy with a lightning scar on his head greeted us, and the giant asked: "New ter 'Ogwarts? 'Arry's too." We nodded. Lavinia asked curiously: "What's up with Harry's forehead?" The giant's expression turned serious, and if I was correct, a flash of fear flashed across his eyes. "Not 'ere to talk abou'." He said gruffly. Harry stuck out his hand with curiosity in his eyes: "Hi, my name is Harry Potter." We shook hands and introduced ourselves. Hagrid led us in, and Harry was swarmed by fans. 

After we shook them off, Reyna whispered: "That Quirell character looks kinda fishy." Hagrid shook his massive head, stopping in front of a big wall: "'e's a professor." He tapped a pink umbrella on a brick, and the bricks rumbled and twisted and formed a doorway. "Wow," Said Will as he stared at the doorway. "I know there's magic, but I never imagined it can be like this!"

The doorway isn't a normal corridor, either. Harry stepped inside and exclaimed: "This is, like, the dream shops!" Hagrid ushered us in. "Now we 'ave to go to Gringotts and get 'arry his money." He scrutinized us closely. Hazel said hurriedly that we already have the money, trying not to expose the fact that we're not wizards, but demigods.

"Come on!" said Sadie, excited, and bounded off. Harry followed, starting a conversation with her. 

There were owls, pets, potion ingredients, etc, etc. Hagrid led us to the clothes store, where a plump woman is fitting clothes onto a boy that looks like a child of Athena. He certainly didn't behave like that, though. We took turns. When Annabeth came back, she said to Harry: "This boy is the classic bully." Harry went up. When he came back, he whispered: "This one is spoiled, bratty and an idiot." We laughed.

Please don't be a ghost reader, and comment if my ideas are bad!
