Draco Malfoy, for all his money, prestige and pure-blooded bigotry, had decided to try and attack Harry through his friends long before that battle and on October 15th had lured Hermione to a secluded classroom with the full intention of raping her. He had been polyjuiced to look like Ron and Hermione thought she was simply going to get in some kissing between classes. Harry had followed her when he caught a sense of something being off from his friend. Later, he found that the perfume that she had gotten as a birthday present had reacted to a spell Malfoy had shot at her, leaching common sense out of the intended victim. It wasn't a dark potion but only semantics kept it from being labeled as such.
Harry slipped into blackness and attached himself to her shadow, walking down the same corridors she went through. When she met Malfoy, he calmly explained what he was going to do and how she wasn't going to remember anything other than Ron having taken her at Harry's insistence. Hermione's eyes were still glazed over from the effects of the spell while she started to disrobe, Malfoy laughing at the irony of it. Harry had heard enough and stunned his friend. He then disarmed Malfoy and ripped into his mind to find anything of potential value. Blood freely running out of his nose from the intrusion, Malfoy started to talk some smack at his arch nemesis, not really understanding how outclassed he really was.
Harry summoned the tainted perfume and poured it down Malfoy's mouth. A few minutes later as the potion took effect, Harry asked Malfoy to go take a swim in the lower part of the lake. Without the benefit of a bubble head charm or any other air. Malfoy agreed that that sounded like a grand idea and out he went. Harry, feeling guilty at the impending demise, then summoned some raw meat to stuff into Malfoy's pockets to get the merpeople good and riled up to rip him apart. Which they did and no one was any more aware of it than he was. Certainly not Hermione who didn't remember anything from that afternoon once she woke up back in her bed just prior to dinner.
He thought about that day every now and then. He wasn't really sorry about what he had done. He had removed a potential adversary. He was an annoyance when it was just Malfoy vs. Potter. But when he decided to take his sick fantasies out on his friends, he was a liability that needed removing. He regretted that Malfoy had gone down the path he did, but it was his choice.
After gathering his thoughts he decided to go visit Ginny's grave. He went there at least once every week. Sometimes more, never less. He was going to marry her; they were going to have a fine house. Even get a dog before they had children. She was going to show him the wonders of the world. Take him to see an ocean, or a desert in Egypt. They'd had plans.
Then all that crap happened. Voldemort. That big s-o-b. And now he wouldn't live a happy ending. He was alone again.
Ginny was buried at Godric's Hollow near his parents. Harry had requested it since she was his intended. The Weasleys made no objection; they were happy that Harry had loved Ginny so much that he wanted her buried in the Potter cemetery.
Now standing in front of her grave, Harry conjured hundreds of red roses to place around her tombstone.
"Hi, Ginny. It's me again," Harry started, sitting down on the cool grass.
After an hour of talking about what was happening at school, Harry sat there and stared at her grave. He sighed to himself. He didn't cry - the tears were no longer coming like they used to. He guessed he must be healing somewhat. He knew from Dumbledore that death wasn't just an end but the start of another adventure.
An adventure he wanted to accompany his dead girlfriend with, not alone. After a half hour of silence he laid his head on her grave and looked up to the stars. The quiet sounds of nature could be heard in the distance. Crickets, frogs, other creatures making noise. No humans.
Harry noticed a shooting star burning in the sky. Deciding to try his luck, he made a wish. "I wish I wasn't alone anymore. I wish I had a new life," he said as his eyes closed following the end of another long day.
After a few minutes, he slowly fell asleep. He could hear the crickets chirping and wondered what they were saying. He wondered if they thought he was crazy for spending as much time as he did at the gravesite. If he had looked at the sky again, he would have seen the shooting star explode into bright red-blue stars similar to when his broken time turner from the battle started to glow and spun backward and then vanished.
