Neville Longbottom.
1) Neville knew he had been young when his parents had been taken into 's, he knew he was barely more than a baby. But he still felt guilty that he didn't remember his parents in their natural state, the only memories of them he has are the ones which repeated every year; them in their hospital bed, reaching out, giving him a sweet wrapper.
His room was full of sweet wrappers, he had a big chest and after each visit he added the new one to the collection. He knew it was stupid, but he just couldn't bear to throw them away.
He loved his grandmother, but sometimes he would give everything to be living with his parents and sometimes he felt so angry at them for fighting the dark side and risking their lives when they had him. How could they have put the death eaters before him? If they hadn't been fighting, maybe they would still be here with him today. Here in mentality and not just physically. He knew he was being selfish and he felt guilty for thinking that way, but he couldn't help the anger which raged through him sometimes.
2) Neville knew his grandmother was disappointed in him, other children his age were turning things different colours and making things explode or float. He couldn't do a thing. She thought he was a squib, he knew she did. He would never forget the relief on her face when he bounced after falling through that window. It made him sad, that she had so little to be proud of him for. When he got his Hogwarts letter, he resolved to do great things at Hogwarts, to live up to his parents. To make his grandmother proud.
3) On the train he heard all the other first years talking about what they could already do, and his heart ached.
When he sat under the sorting hat, he was sure that it was going to announce that there had been a mistake and he didn't have enough magic for Hogwarts. Especially as it took so long making a decision. When it finally called out "GRYFFINDOR" he was so relieved that he had rushed off wearing the hat, a fact Slytherins loved to tease him about. But, he was just happy to have ended up in his parent's house.
4) Teachers tended to bully Neville, or to laugh at him and his lack of talent. At the least, they pitied him. Professor Lupin wasn't like that. He was kind and sympathetic, he would listen when Neville went up to his office and ended up spilling out his soul, he told him stories about his parents who had been at school at the same time as him, he told him they would be proud, that he was like them; he raised his confidence.
5) When the Yule Ball was announced, Neville knew he was going to be the only one without a date. He grew even more sure of that when Hermione, rather sadly, told him she already had said she would go with Viktor Krum. He had never planned on asking Ginny, he had just overheard her talking to her friends about how much she wanted to go. Even so, he was surprised when she accepted his offer.
He had fun that night, he didn't like Ginny in a romantic way (and neither did she, him) but he made a true friend.
6) It wasn't until fourth year that Neville really discovered his love of Herbology. Professor Moody (or the man who said he was, as Neville later found out) had told him how impressed Professor Sprout was with his ability and he suddenly realised that he might actually have a talent at something. Something he could use to make people proud of him.
7) When Neville joined the DA, he finally thought he was doing something his parents would have done. He felt…brave, and like he truly belonged in Gryffindor. When the death eaters escaped he worked ten times harder than anyone else; he knew he was going to truly fight; fight for his parent's revenge.
8) The fight at the Ministry was tragic, life was lost, injuries sustained and true horrors witnessed. But Neville felt strangely elated. He had confronted Bellatrix Lestrange, had fought like a man, had endured the cruciatus curse, had helped save lives, he had lived up to his parents.
9) Neville was ready for the final battle, he was ready for the end of the Wizarding war but he was also ready to win. When Harry, Hermione and Ron came back he knew it was time. He was excited, and eager to start, The faster it started; the faster it was over.
He knew his talents now and he played on them well. He used various plants to attack death eaters, and more than a few of them were defeated by his skill and creativity.
Harry told him that he needed to kill Voldemort's snake, Nagini. It increased his enthusiasm; Harry trusted him with such an important duty; he knew now that he was worthy. When he pulled Godric Gryffindor's sword out of the hat he felt invincible. Here was proof of what was always doubted; he was a true Gryffindor.
He defeated Fenir Greyback, the man who had caused so much pain and conflict to Neville's role model; Remus Lupin. He fought and he fought and he watched Harry defeat Voldemort and together; they all took the victory.
He helped win the Second Wizarding war, just like his parents had done for the first.
10) The day he married Hannah Abbott was the happiest day of his life. It was his day, and all of his friends were there and his Grandmother, and everyone looked so happy. That day seemed to prove that he had finally made people proud and lived up to his parents legacy.
He was certain he would never have a happier day than that, and then two months later Hannah showed him a positive pregnancy test…
