Luna Lovegood Scamander
1) In the beginning, she didn't believe in her dad's stories. Because they just seemed too far fetched, too amazing and bewildering to be real. And besides, whenever he would tell a story her mother would simply give her a look and then smile at him, and Luna took that to mean that the stories weren't real, that her father was just an amazing story teller. It never really occurred to her that her dad might actually believe in them. She just thought they were stories.
Then her mom died, and suddenly she needed something, anything, to grab a hold of, to snatch, to keep her afloat. And her dad's stories were there, in front of her, like a lifeboat. So she grabbed hold, taking the Crumple-Horned Snorkack by the horns and holding on for her life- because here were these stories, that had nothing to do with the fact that her mother had just died, and she put her hope into them, praying that they might prove to be real, that they might take her away from the grief that was piling up in her chest. And then, after pretending to believe for so long, she did.
2) When she first saw the thestrals, she held a grudge against them. Because the only reason she could see them was because she could no longer see her mother, and she hated that something so beautiful (yes, she found them beautiful, graceful, elegant. Had it been any other situation she would have loved them at first sight) could come from something so ugly, so disastrous. And then she learned to forgive the thestrals, because really, it wasn't their fault, was it? Blaming the thestrals for her mother's death wouldn't fix anything, and it was just plain cruel to them.
3) She has good instincts about people. Like, for instance, Ron Weasley. She could sense right away that he was in love with Hermione Granger, even if he hadn't realised it yet (for Luna's part, she never really did understand why, because she didn't understand what could make a person who spent her days with her head buried in her books attractive. And maybe she was a little jealous. But that really didn't matter).
She knew the same about Harry Potter. Not that he was in love with Hermione Granger, but that he would be victorious. She knew in her heart that he would save them all, because she could sense it, that he had potential, and she trusted him. Even when she saw him hanging limp in Hagrid's arms, she refused to believe it. Because she couldn't be wrong. Not because she was arrogant, but because if Harry Potter wasn't there to save them, then who would? She couldn't be wrong. For the sake of humanity, she could not be wrong.
4) She was mad at her dad, furious, when she found out what he had done. That was saying a lot, because she rarely ever got mad. She simply didn't see the point of releasing such negative energy. But when she found out that he was ready to betray Harry Potter, despite everything she had ever told him, even through all of the things he had written about him, she was angry. She just couldn't believe he would go against the side he had claimed to support, that he would turn over the only chance of survival to You-Know-Who, that he would sacrifice so many lives to save the life of his daughter.
She then thought it over. And really, he couldn't be blamed. Because he didn't know what he was doing, due to grief and anxiety. Besides, he had already lost his wife. She could understand that he didn't want to lose his only daughter, too.
5) It never really bothered her that others ridiculed her, or that they hid her stuff. Because it was all just fun and games. Because those people weren't her friends. She didn't care what they thought, because really, why would she? She wouldn't let people who didn't know her affect her life. And maybe it took her a little longer then normal to find them, but she did get friends. And she loved them, because they were her friends. Maybe they thought her a little weird, but that was okay. She wasn't perfect, and nor were they. Hermione was too bookish, Harry too independent, Ron too sarcastic, always letting humour lead his life. But she never dwelled on those things, because they were her friends. And you don't let things like that get in the way of your friendships.
6) She always got along best with Neville. Because even though both her and Harry had lost a parent, in his case, both, Neville had lost his too. Maybe they weren't dead in the physical sense, but they were dead to Neville. Because at least Luna had spent time with her mother, at least she had known her, had known what it was like to be loved by her. But she couldn't imagine what it would be like to be so close to your parents, and yet so far away. She couldn't imagine the pain that would come from having your parents look at you with no realisation. And one night, when they were up on the Astronomy Tower talking about this, Luna leaned in and kissed Neville. When she pulled away he smiled at her, and she smiled back, because it had been nice, comforting. Nothing had ever come of it; she knew nothing would, for it had been evident that neither had felt anything. But she still always felt a certain affection for Neville.
Despite this, Ginny would always have a special place in her heart for that night in the hospital, after the birth of Lily, when she called her into the room and told her, with a big smile on her face and a little tiny girl with a mop of red hair already on her head, that she was looking at Lily Luna Potter, and then asked her if she would be her godmother (she of course said yes).
7) When she finally came to terms and accepted that some of her dad's mythical creatures, like the Crumple Horned Snorkack, didn't exist, it hurt a little bit. Because she had always trusted her father, and she had always believed in everything he had ever said. But then she found a numerous amount of other creatures, creatures even her father didn't know about, and she realised that it didn't matter whether some of the stories weren't true, because the most important thing was that her father had given her this love and this fascination for the creatures she found and nurtured. And really, he had led her to her most important find of all- Rolf.
8) Lysander doesn't like his name- she knows because a few days after he went to Hogwarts he wrote home telling her that everyone made fun of his name and his brother's name, and why on earth couldn't she have named them something normal, like Richard or Peter. Luna felt really bad after reading that letter, and when a letter came a few days later from Lorcan she expected the worst.
But he simply said that he was having an amazing time, and that Hogwarts was just as magnificent as she had told him it was. He wrote saying that he and Lysander had reunited with Lily Potter, and that Luna was right, the slight age difference didn't mean anything, they were still as close as they had ever been. He told her that both he and his brother were in Ravenclaw as well, with Rose Weasley. He didn't mention anything about his name. But Luna still felt a bit guilty about it, for a while anyway.
9) Lysander only pretends to believe in her stories. She can tell, because that's what she did for so many years. He smiles and goes along with what she says, what she tells him, even as Lorcan hangs on to her every word. But it's okay that he doesn't believe in them, she's okay with that, and if it took what Luna had gone through in order to believe in the stories, she hoped he never believed in them.
10) She had always harboured hopes that at least one of her children would fall for a Potter or a Weasley. She had always thought that it would be Lorcan and Lily, because they were closer friends and were around each other more than she was around Lysander. So she was surprised when Lysander tentatively told her that he had feelings for Lily Potter, but he was afraid, because she was older than him. Luna told him that that probably shouldn't matter, and when he came to her a few days later, telling her that he had kissed her and she had kissed him back, she was ecstatic. Because now her friends would become her family (if things worked out, of course), and nothing could be better then that.
Alright, that was Luna. Scorpius is up next, and then is Ron. I'm thinking after Ron I'm going to write Harry (which would make sense, as the books are written primarily about him!) and I would crack a shot at some minor characters, like Blaise Zabini, because I love that boy, and for wrenbailey.
