Thalia and Reyna's jaws dropped as the brick wall rearranged itself to reveal a large square full of witches and wizards shopping in the strangest of stores.
"Woah. How the, what the, who?" Reyna could hardly speak partly due to the fact the fact that she had just seen her first glimpse of magic and also because when the brick wall had started to move Thalia had jumped back and grabbed Reyna's arm and still hadn't let go.
"Magic duh. Honestly mate, you two are acting like you've never seen magic before." (Bet you can guess who said that.)
"Ronald!" The bushy haired girl, Hermione, scolded the rude ginger who was apparently named Ronald while the black haired guy who had obviously done so something to anger Zeus resulting in the lightning shaped scar on his forehead, Harry, rolled his eyes while Ronald's sister laughed.
"Well sorry your rudeness we just don't have magic like this in the states." Thalia snapped at Ronald.
"Thalia calm down. He didn't know." Reyna placed her hand gently on Thalia's. Thalia looked down and blushed, quickly removing her hand.
"Whatever let's just go to the bank, get our money, and get our school stuff."
"Right. Follow me to Gringotts."
Thalia snickered and started a conversation with Reyna in Latin.(Jason taught her Latin)

Anything they say in Latin will be in Italics. Also T stands for what Thalia says and R for what Reyna says during their Latin conversations.

T: Is it just me or are wizards really bad at naming things.
R: Stop picking on them. We have weird names too. Like Medusa and Minotaur.
T: They're not as weird as Green Tots and Moldy Shorts. Also, you do know Percy fought those guys right?
R: What?! Percy fought the Minotaur and Medusa?! How is he still alive?!
T: He's Kelp Head, need I say any more? Also, he defeated the Minotaur twice, once when he came to camp the first time and then during the battle of Manhattan. And he defeated Medusa on his first quest, about a week after he got to Camp Half-Blood.
R: How in Juno did he survive with no training?
Juno: (In Manhattan having her cows leave "presents" where Annabeth was staying with Percy.) Don't refer to me as hell!
T: As I said before, he's Percy who knows how he survived.

The Weasleys, Harry, and Hermione were watching them in confusion.
"What bloody language are you loons speaking?!" (Guess who said that)
"Latin, we learn it at our school as well as Greek."
"Oh. Those our interesting languages to be required to learn. I don't suppose you could teach me?"
"Maybe some day. Now why have we stopped?
"Oh, we've arrived at Gringotts."
Thalia and Reyna looked up to see a massive bank built out of polished white marble.
"Woah. Annie would love this."
"Who's Annie?"
"Just a really good friend."
"Oh. Well let's go get our money."
With those words they eagerly entered Gringotts.
