He couldn't count on Hermione to save his ass every time he found himself in trouble in the future. His only other potential ally he could think of was Neville Longbottom, and Neville was a far cry from someone who would be useful in battle. Neville was an abused under-confident child just like Harry was, and would have his own problems to overcome.
"Dobby," he whispered, hoping the Elf would would come.
"Yes Harry Potter sir," the diminutive green being said with exuberance.
"Dobby, do you wish to be my house Elf?"
His eyes widened. The incredibly loyal being looked like Christmas had just been declared to be every day of the year.
"Yes sir, Harry Potter Sir. Dobby would love to be his Elf."
"How do I do that?"
Dobby reached over and grabbed Harry's hand. Instantly he felt a bond between the two form. It felt pure and comforting. He knew Dobby was loyal to him and him alone, and that he could trust him with his life.
"Dobby, I need to get out of Hogwarts. I need you to quietly pack up all my belongings in my room, get out my invisibility cloak, and bring it all here."
A minute later, Dobby returned with all his chest, cloak, and an outfit to wear outside of the hospital. With a deep breath, Harry stretched and snuck out of the hospital. The hastily put together plan seemed to have succeeded so far.
His goal: Diagon Alley and the Gringotts Bank branch located there.
He needed to get from Hogwarts to there, and he needed to do it immediately. With his belongings packed, he shrunk his school chest and donned his father's invisibility cloak. Thirty minutes later, after a quick jaunt through a Hogwarts secret passageway, he found himself emerging from the basement of Honeydukes, the sweet shop in Hogsmeade village. A quick run to "the Three Broomsticks" tavern and some stolen floo powder found himself emerging from the fireplace in Diagon Alley's Leaky Cauldron in London. Elapsed time thus far, twenty minutes.
He was easily able to sneak through the alley undetected, and wisely took off his cloak as he ascended the steps to Gringotts. After all, it wouldn't be a very smart thing to sneak into a bank where guards would sooner kill you than look at you while wearing a device such as a invisibility cloak.
Those few fleeting moments on the steps of that bank would be the last time Harry James Potter was seen in public for nearly two and half years.

Harry continued to sit on the bed, lost in the memories of what followed the acceptance of his heritage. The grief, the rage, and finally, the happiness of having actual physical things that belonged to his parents in his hands other than an old invisibility cloak.
The goblins were extremely helpful with finding trainers for Harry. He withdrew from Hogwarts and applied himself towards learning everything and anything that could possibly assist him. He trained his body, his mind, and even his soul. The magical "leech" in his scar was removed, setting Harry's mind at ease and giving him the first true period of uninterrupted sleep in his lifetime. The power boost he received after the leach's removal was also incredibly substantial.
Open war broke out within a week of Harry's removal of the soul fragment embedded in the scar. He later learned through the interrogation of a high-ranked prisoner that Voldemort had been attempting to influence Harry through the mental link embedded in the scar. The Dark Lord's goal was for Harry to stupidly wander into the Ministry of magic and steal a prophecy orb for him located in the Department of Mysteries. With this no longer an option, Voldemort had to steal it himself, which through his own poorly devised plan, exposed him publicly far sooner than he wanted.
Before that summer was finished, the news was out. Voldemort was back and Harry Potter wasn't a liar. But even then, Harry did not make any public appearances. Decrees were passed by the Wizengamot, declaring him a traitor to Britain unless he returned to fight the Dark Lord, but he ignored each and every one. He went through a crash course of magical combat far more intensive than had been seen in centuries. It was during this period, he discovered the love of his life.
Runes.
Runes could do everything Magic could do, but only better. They were static, predictable, and could be overpowered via Harry's insanely high magic levels to never break down even if subjected to simultaneous drains by hundreds of other normal wizards.
Eventually, Harry deemed his training adequate for the initial strike against his enemies. Magical Britain had taken no direct actions to combat the treasonous faction. They weren't even bothering to pursue them. The Death Eaters would never be defeated so long as the current toadies for Voldemort were entrenched in the legislature. As long as they held power, they could hold up the process for as long as needed to ensure the Dark Lord's ultimate victory.
So Harry had no choice. It was easy after all. All he did was compare each piece of legislation that helped Voldemort and which pieces that would aid muggleborns and compare who voted for what. It conveniently, gave him a very specific list of people who voted the same way each time.
He waited for a Wizengamot meeting where Dumbledore was out of the country on business. He stormed the Wizengamot and killed one-third of its members in the middle of a session. He left the room in ruins, each dead body with their left sleeve cut off, showing they were branded servants of the Dark Lord.
The action immediately alienated himself from both sides of the war, but it wasn't like he cared. He had already been declared a criminal and a traitor to Magical England, but at least now, he had done something to earn those charges. He was happy with the result since the government was free to make laws that actually targeted Death Eaters.
