A brief summary of what happened in the last chapter of Harry Potter and the Deathly Hallows:
"Chapter 36: A Flaw In The Plan
When he opens his eyes again he's back in the forest, facedown on the ground. He hears Voldemort, who is on the ground as well, telling someone to make sure he's dead. Soft hands touch his face, and a whisper asking if Draco is alive. He whispers that he is, and Narcissa yells back to the crowd that Harry is, indeed, dead. Voldemort makes Hagrid carry him back up to the castle to show everyone that he's dead.
When they reach the grounds all the fighters of Hogwarts come out. Harry is still pretending to be dead, and his heart hurts to hear their grief for him. As Voldemort tortures Neville for trying to defy him, several things happen at once. Centaurs flood the grounds, shooting arrows at the Death Eaters, Grawp comes bursting out of the forest, and Neville manages to slice off Nagini's head with Gryffindor's sword, which he pulls out of the Sorting Hat.
A new battle rages on, and Voldemort runs into Hogwarts. Under his cloak, Harry follows him, intent on ending it for good. The battle is fierce, and Harry winds in and out, determined to get to Voldemort.
He watches in amazement as Mrs. Weasley kills Bellatrix Lestrange in an epic duel. Voldemort turns to kill Mrs. Weasley in return, and Harry unveils himself at last. The entire hall erupts in cheers and then silence as he and Voldemort circle each other, preparing to duel at last.
Harry tells Voldemort many interesting things as they circle each other, and he tries to get him to feel some remorse for what he's done. Voldemort, of course, doesn't believe anything Harry tells him, and when the spell is finally cast it's over in a moment. Voldemort is dead, and Harry is left alive, the true master of the Elder Wand.
After it's over Harry wants nothing but to be alone. He sneaks out with Ron and Hermione in order to tell them everything that happened. They go up to Dumbledore's office for one last talk with the Headmaster's portrait, and Harry decides to put back the Elder Wand because it causes more trouble than it's worth. Dumbledore, it turns out, agrees with him. Before returning the Elder Wand, however, Harry uses it one last time to repair his broken wand."

Harry smiled faintly at the painting of his former headmaster before turning to the door with the two wands. He walked with Ron and Hermione, who were hand in hand, out of his office. Seeing the closeness of his two best friend's made him want nothing more than to embrace Ginny and remain that way until it was time to leave the castle. However there had been a few last things on his mind that he had wanted to take care of before finding her.
Stepping down from the stairs leading from the headmaster's office, he walked out into the abandoned corridor. The tapestry that hung so feebly now at the windows appeared battered and torn, the cloth darkened in places where perhaps a hot spell or curse had struck it, still leaving it in tact. The marble floor was covered in scattered shards of broken tinted glass that had come from the windows. A few discarded wands lay amongst the glass as well, some cracked or broken. There were fragments of statues strewn about and pools of blood, but the bodies had been moved. Harry looked up to see candle chandeliers burnt out and hanging as if by a thread. He pulled out his wand and waved it over the hall in a sweeping motion, focusing on what he wanted to happen to the mess, just as Dumbledore had the prior year when he had met Slughorn. The broken glass returned to their windows, the tapestry looked reupholstered, the fragments of metal and wood returned to their statues, and the blood that had been shed for him cleaned up, but the wands remained as they were. Harry decided he would collect them up as he went about the rest of the castle doing this. He felt it was only right. Ron and Hermione followed silently, knowing Harry wanted to put his school back to the way it had been when they left it their sixth year.
They turned a corner where a few students lingered and passed by, some hobbling their way to the Great Hall to be treated. The three Malfoy's were making their way up the hall, with their son leading the way ahead. "Draco -" Harry paused, waiting to see if he would stop for him. Lucious sneered and kept a watch on him.
"O-on a first name basis now, Potter? What i-is it?" he stammered, obviously taken aback by Harry calling out his name.
"We saved your life twice, didn't we? Even as you were clearly on Voldemort's side. Don't make me regret that choice, Draco. I think you'll be quite happy that I've stopped you."
Draco looked around humiliated and hoping no one was close enough to see. He looked down for a moment to considerate, then back up at Harry, "Erm, thanks. . .P-po. . .Harry. Though I can hardly see why I'd be happy right now".
"Other then the fact you're still alive?," Harry pulled a wand out from a pocket in his cloak. Draco's wand. "I thought you would still be needing this." He held out his hand to relinquish it, but pulled back hesitantly as Draco reached out for it. "That is, if you vow to leave the life you've been living. Stop living in your father's shadow and doing only what would please him. I've seen how unhappy it makes you. But vow to me that you will make the right choices now. Draco?"
He nodded and thanked him again, though it was merely a whisper. Harry saw, or hoped he saw meaning and truth in his eyes. Draco took the wand and the two parted. Harry walked down to the Great Hall but stopped as he remembered that he still had the Elder Wand. He sighed to himself, still wanting the contentment of holding and seeing Ginny at last when he stepped into the Great Hall, but he turned to leave the castle and return the wand to Dumbledore's tomb.
Harry looked upon the wreckage and back to the castle. He felt incredible remorse for the fellow students who were harmed and killed out here, teachers and Order members alike. The mess had been caused for him, over him. Even the Death Eaters were people who, though he did not care for, died over his life. All so Voldemort could have him. Though just as suddenly as his remorse had struck him, relief took over. It was done, the battle was finished and his quest was overcome much better than he had expected. And Harry felt glad because Voldemort had been wrong. He had been called a fool and was told he would lose everything. But now Harry counted his blessings. He had a home to return to, his best friend's were alive and well. The majority of their two families were safe. Hogwarts was still standing, Hagrid and a number of teachers were alright. His mouth twitched into a half smile as he waved his wand again, restoring anything he could of the grounds in front of him. He continued to walk around doing so until he reached the other side where the lake was.
He walked slowly over to the lake, near where his deceased headmaster was buried. Voldemort had not taken any liberty in refilling the grave and Harry almost wanted to do it himself, without magic just as he had done for Dobby. He decided against it though as he wanted to get back to the castle. Fumbling for the Elder wand, he crouched by the tomb and opened it with his own wand. He looked at the peacefully resting man, which was to his surprise easier than he had expected. He guessed perhaps it was because he had seen him only a few hours before, even if it was however, in his head. Harry rested the wand in Dumbledore's hand and resealed the lid. He stood back and took a moment of silence yet again, as if Dumbledore had only just died in the final battle. Ron and Hermione stood at his side. He looked over, expecting Hermione to have tears in her eyes, but it seemed as though she shared his feelings. Or so at least he had hoped. Harry make a final flick of his wand and sent the pile of dirt back over Dumbledore's grave. Ron pulled out his wand next and fixed some near-by flowers over it, much to both Harry and Hermione's surprise. Lastly Hermione restored the headstone that marked the grave and the three turned to leave.
"Harry," started Hermione, who only stopped because she feared he might shoot her a glance to silence her as they walked, but he let her continue, "We're really very proud of you.", she gestured to herself and Ron, "You've always made the right choices in the end. What you did with Elder Wand was exceptionally mature of you. I can understand any feelings of loss Harry, but you ended what this world needed to end most. I also want to thank you for that." she looked at him, her eyes swimming with hope that he would not try to make an excuse for what she had said.
"Oh, thanks. I knew in the end what I had to do. I'm not sure anyone knows how badly I had wanted to die. But in the end it all worked, didn't it? And you're welcome Hermione, even though I should really be thanking you for putting up with me and sticking with me. The both of you."
They were at the castle now. At least reentering it had not been a sore sight as Harry had already fixed up the inside. The three of them clambered back upstairs, sore from all their misadventures. They were satisfied that they would not, as far as they know, have to deal with anything like that again in their lives. They reached the top of the stairs and walked through the front to the Great Hall, finally.
A remnant of grief filled the hall, accompanied by the thoughtful happiness of being safe with friends, though tears poured or streaked everyone's faces. Some had looked up as Harry walked in, a few gave him a faint smile or nod, occasionally a wave in his direction. A part of him wanted to address everyone sitting in the room, to thank them and tell him how sorry he was for their losses, as it was a great loss to him too. But he continued up to the front of the hall and brought Professor McGonagall the wands he had collected. She took them, barely nodding her thanks to him and let him go. He was happy she did not ask him anything of it. He walked until he found the Weasley's huddled together, talking in broken and deeply pained voices. Another painful blow struck him as their voices brought back the pristine visual that was the murder of his friend. The one's he thought of as family.
He sat down beside Mrs. Weasley, who he did not think could stop crying for the life of her. After all, Harry remembered, the boggart back at Grimmauld place had been of her son sprawled on the floor. Her worst fear, to lose the life of a loved one, a family member, was her deepest and biggest fear brought to life. He put an arm around her to console but did not say a word, he was not sure what he could say but he guessed that she would know that.
Hermione sat next to Harry with Ron's arms around her on her opposite side, both of them silent, sitting there in what seemed to be perpetual grief. Their head's were down together and Harry could see tears collecting on the table beneath their hidden faces. He was not sure if it was from the both of them or just Hermione, but it did not make a difference. Ginny was seated next to her mother, her head still resting on her shoulder which had only moved to see Harry once as he came to sit with them. She had looked at him sort of longingly, which he was sure he had made an expression that showed the same in return, but she turned away to stay with her mother and father. Mr. Weasley was next to her, discussing arrangements with George, Percy, and Bill across the table. Fleur was sitting on the end next to Bill, across from no one. She was silent and crying while Bill rubbed her shoulder, his arm around her comfortingly.
"Of course there will be room at home for all of us, but I'm sure Hermione will want to see her parents again. Harry, I'm sure has business to attend to. And you two," Mr. Weasley nodded to Bill and Fleur, "I'm sure would like to finally be home without disruptions." he finished.
"Actually, if you don't mind Mr. Wesley, I'd like to stay for the funeral. Get myself together before seeing my parents as well.", said Hermione. Her voice sounded weak and strained. Ron looked at her momentarily. At first happy that she wanted to stay, but then upset as she mentioned she would still be leaving to see her parents. Harry wondered if Ron would make it to go with her, if she would let him.
"Bill and I would like to come and ze you too." Fleur tried to smile at Mr. Wealsey and Bill nodded at his father in agreement.
"If you would prefer it, I'm sure it would be no problem." Mr Weasley glanced at his wife as he said this, but she only nodded.
"I'd prefer it too.", Harry put out there simply. Hearing his own voice was suddenly strange to him. Mr. Weasley nodded his approval. George made an attempt to grin at them for wanting to be there for his twin's funeral but turned away quickly, looking back to his father.
"Well, dear's," Mrs. Weasley cleared her throat, she sounded quiet and tried to make herself sound more relaxed, which had not worked, "Are we ready to return then?". George tried again to smile at her but that attempt had not worked well either. Each of them stood up and dissaperated, except for Ginny who had to hold on to her mother's arm for assistance. The scene around them blurred as they each took a deep breath and closed their eyes.
