Percy Jackson couldn't believe what he was seeing. His old friend, Luke Castellen was standing right there, looking like he did before Kronos possessed him.

"Luke!" Annabeth cried, throwing her arms around him.

"Hey Annie," he said softly.

"What, how?" Percy asked, dumb founded.

"I escaped the doors of death, right after Geae kidnapped Thantos."

"And you're here, like, totally not possessed and everything?" Percy asked again.

"Yup." Luke looked at Percy and Annabeth. "And I wanted to say, I am so sorry."

"Move!" Was heard from the crowd, as well as a good handful of people being shoved out of the way. A girl in silvery clothing and punk hair emerged from the crowd. "Luke?"

"Thalia?" Luke asked, smiling.

"Hate to break up this cute little reunion," Leo interrupted, "but who the Hades are you?" He pointed to Luke.

"Luke Castellen," Luke introduced himself, "Son of Hermes and former cabin leader."

"Oh yeah, you're like the super evil guy who-" Leo was cut short by Piper and Annabeth smacking him upside the head.

"Shut up, Repair Boy."

"Hey-"

"-Luke," two identical voices called out. Luke turned around only to see his siblings, the Stolls, dump a bucket of grape Gatorade on him.

The next two days at camp were intense. Both the Greeks and the Romans agreed on peace (though Octavian stage whispered to everyone that they could still beat the other side). They created a new camp, Camp Demigod.

Yes, an entire new camp was born in two days.

The third day they were back, Annabeth woke Percy.

"Seaweed Brain, get up!" She yelled.

"Wha- blue candy- I'M UP!" He said, sitting up straight.

"Well I didn't want you to be late when you're visiting your mom."

"Wha-"

"You said yesterday that you wanted to go into New York City and visit your mom," Annabeth said slowly.

"Oh yeah," Percy mumbled.

So there he was, sitting on the Subway, ready to take it to his mom's apartment in Manhattan.

"Can we, Harry?" A ginger haired girl begged a boy that looked much like Percy himself.

"Esh fine, we'll pick a hotel in Manhattan."

The ginger haired girl pecked the boy's cheek, and a guy who Percy assumed to be her brother contorted in disgust.

"Enough with the PDA you two!" The girl stuck her tongue out.

Soon enough, it was the stop for the Manhattan station. Percy got off, bumping into the guy who had been talking to the ginger haired girl and boy.

"Sorry mate," he said, coming to face Percy.

"No, problem," Percy muttered, staring incredulously at the boy's head. Peaking out from a mop of messy black hair, was a scar in the shape of a lightning bolt.

Harry Potter wished the Subway maps weren't so confusing. When the plane had finally set down on the ground, Harry had to keep himself from kissing the pavement. Ron was as fascinated with the plane terminal as his dad would have been. Harry and Hermoine had to keep him from stuffing himself in the luggage pick up.

Now they face a new challenge.

Getting to their hotel.

It was suppose to be directly in New York City, with a room for the girls and a room for the boys. Harry considered getting a taxi, but then Hermoine smacked him on the back of his head.

"Do you know anything about New York? It's impossible to get a taxi at this time."

"So then how do you suggest we get there?" Ron asked, munching on a giant soft pretzel.

Hermonie gulped. "The Subway."

Harry didn't get how they could ride a sandwhich to their hotel.

Soon, he found out that the 'Subway' was a train system, much like the Tube in London.

After carefully studying the network of lines with Hermoine, he concluded that they take the B Train.

Unfortunately the B Train took them to Chinatown, so they got on the C Train.

Which was taking them to Manhattan.

"Can we Harry," Ginny pleaded. She had been complaining about motion sickness from the ride.

"Esh fine, we can get a hotel in Manhattan." Ginny placed a kiss on Harry's cheek, must to the disgust of Ron.

"Enough with the PDA you two!" Ron cried. Ginny stuck her tongue out.

Harry noticed a boy, seventeen probably, watching them discreetly. He looked like Harry, only his eyes where more sea-green.

When Ginny said she was about to puke, the train came to a stop, for Manhattan station.

Ginny raced for the exit, with Ron and Hermoine strolling after her. Harry rushed after her, only to run right into the boy who had been watching them earlier.

"Sorry mate," he said, trying to steady himself. The boy was staring at his scar. Harry hated it when this happened.

"It's my fault," the boy said slowly.

"I wasn't watching where I was going," Harry apologied.

"As was I," the boy replied. He held out his hand for Harry to shake, looking at him carefully, "The name's Percy Jackson."

Harry shook Percy's hand. "Harry Potter."

Then the window exploded.
