A/N: This is a crossover between Harry Potter, The Mortal Instruments, Kane Chronicles and Percy Jackson. Just a little something I wrote for my friend in study hall. The couples, in order of appearance, are Romione, Sizabelle, Clace, Walt/Sadie, and Percabeth. I don't own any of these characters or their stories.

As you walk down the streets of New York on Christmas Eve you smile. It's a perfect night, snow gently falling, lights glimmering, children shrieking. You duck into the Spring Street subway station, it's much warmer in the station so you slip off your hat, and put your gloves into your pockets. You look at the people around smiling. A married couple, tourists by the look of their fanny packs and perplexed expressions while they look at the subway map argue.

"Ronald, I told you we have to take the six train!" one of the tourists with bushy, brown hair argues as she crosses her arms.

"We have to go uptown, not downtown!" her husband argues.

"The six train does take you uptown, you don't know any thing about muggle inventions anyways!"

"Fine, have it your way, but if we're late Harry and Ginny will kill us, I doubt they can handle all five kids," Ronald says as the six train pulls into the station.

You're confused what they mean about muggles but you just get into the car in front of you and take a seat across from a group of teenagers with strange tattoos. You've heard weirder things in New York anyway.

Two of the teenagers, a blonde haired guy, and a petite redhead promptly start making out, casing the other two to gag.

"Really, I get that you haven't been able to touch each other in ages, but really? In a subway car?" one of the teenagers interrupts the couple's make-out session, pushing her long, dark hair behind her ear.

"I have to agree with Izzy on this one, you don't see us making out everywhere," a pale, dark haired boy chimes in.

Their conversation is interrupted when the train reaches its next stop. The teenagers get out, and the doors slide closed. A couple stops later you get out, and climb the stairs into the chilly night.

You reach Central Park after a few blocks. You mindlessly walk down the pathways just thinking and taking in the beauty of the snow. You sit down on a bench so you can people watch.

First a man in a suit goes by, talking furiously on the phone, next an old lady with two rambunctious kids, next a couple, an dark skinned boy with hypnotizing eyes, and a small, fair girl with pink streaks in her hair. They're wearing ridiculous linen outfits, completely impractical for the weather, but they don't seem to notice. They laugh as they cling on to each other, laughing at a joke you didn't hear.

You sit for who knows how long, lost in your own thoughts until a couple sits next to you. They laugh as they stare into each other's eyes, whispering thoughts for only them to hear. The girl is pretty, with curly blonde hair, grey eyes, and a tan you'd kill for. The boy has dark hair, and green eyes. He laughs as he feeds the girl a blue M&M.

"What time do we have to be at your mom's?" the girl asks.

"Ummm, I don't really know," the boy replies running his hands through his hair.

"You are such a seaweed brain," the girl smiles, "I think she might of texted me the time,"

"Hey, how come you get a phone, and I don't!" the boy crosses his arms.

"Because I've been at Camp the longest!" she smirks, then looks down at her phone, "Zeus!" she exclaims, you are slightly confused by her choice of words, but shake it off. "We were supposed to be there a half hour ago!"

They sprint down the path, using a few choice words, and you smile to yourself. You look down at your watch, and realize you only have fourty-five minutes until you have to be at your parents. You stand up, and brush the snow from your butt, and start to walk home.
