Harry sat glaring at the ceiling of the hospital wing. Madam Pomfrey was bustling about trying to heal the injured. Harry felt guilty looking at all this, he felt that he caused it. Damn Dumbledore for not telling him about himself being a Horcrux. He could have stopped this. Harry sighed and realized what he had to do. Run.
He waited until everyone was asleep and slipped his invisibility cloak over himself. He again checked to make sure no one was watching and left the infirmary. He stalked across the grounds of Hogwarts, still stained in blood and destroyed, confirming his thoughts that he caused this mess. Once he hit the apparation point, he turned took off cloak and apparted to the tent he, Ron, and Hermione were in before being taken to Malfoy Manor. He grabbed his supplies and put them in a bag before apparting to a forest near Ireland.
Thats when he snapped his wands. He then buried each half of both his wands in separate areas. It was time for him to stop using magic. He knew that because of apparting he could be traced to where he apparated so he immediately started stalking toward Ireland, where he would take an international portkey to America.
A few days later, he had arrived just outside New York City. He knew that all of wizarding Britain would realize that he is missing, so he was carefully covering his tracks.
He dyed his hair blonde with blue tips and was growing it out. He also got coloured contacts that were a crystal blue. Once he got a job and money, he was gonna start getting tattoos and piercings. He was working on adapting an American accent. Britain was long forgotten. Mostly.
He walked into the nearest bar and applied for a job, which he was instantly given. He was told to get better clothes though. He agreed.
He walked into a gothic looking store and bought tight black leather pants and a dark purple satin shirt, a emerald green light weight shirt, and a few other dark coloured shirts. He got a pair of white converse and a black sharpie to draw on them when he got bored.
He then went to muggle plastic surgeon to inquire about getting his scar removed. He made an appointment for a few weeks later to get it removed.
He went to a cheap inn and rented a room for the night, never once did he think about those he left behind in Britain.
He woke feeling oddly refreshed and git ready for his first day at the bar. He really hoped the Ministry wasn't tracking him. He wanted to be left alone.
He showered and put on some of his new clothes.
He didn't have to be at work until 7 pm, so he took some time to walk around the city.
He instantly fell in love with Central Park. He walked idly for hours, his mind wandering every where. He wondered what was going on in Britain now that he was gone. He listened to others conversations to try to differentiate between the English and American accents. He even wondered about his new job.
At 6:30, he went back to his flat- apartment- and changed and ran to the bar.
Alex, the main barman trained him that night. He met quite a few of the regulars, and was told some interesting stories. Nothing to compare to his yet though.
After a few days, he quickly fell into a routine of doing things- he even found the "Diagon Alley" of NYC. It wasn't called that though, at least Harry didn't think so.
There he picked up book to help him in obtaining his NEWTS, and all new supplies. New robes, new cauldrons, and even a new wand. He realized he had taken magic for-granted, and never knew just when he might need to use it. He needed the wand for emergencies, robes for walking this "Diagon Alley," and a cauldron for potions that have medicinal purposes. After being gone from magic for days, he knew he just couldn't up and leave. He just needed a new identity.
He went to the American Gringotts branch, and pulled every thing out of his vaults and shut them down. He knew the British Ministry could trace that, so that night he left to head to Las Angeles.
Meanwhile in Britain, every one was going crazy looking for their hero. Their lead stopped somewhere in Virginia. They could tell he was being careful about everything. It took them days to figure that much out. So they were quite elated when Gringotts contacted them saying that Harry just withdrew everything from their branch in NYC.
