“Mistletoe," said Luna dreamily, pointing at a large clump of white berries placed almost over Harry's head. He jumped out from under it. "Good thinking," said Luna seriously. "It's often infested with nargles.”

“Hello' said a vague and dreamy voice from behind them. Harry looked up: Luna Lovegood had drifted over from the Ravenclaw table. Many people were staring at her and few people openly laughing and pointing; she had managed to procure a hat shaped like a life-size lion's head, which was perched precariously on her head.'I'm supporting Gryffindor' said Luna, pointing unnecessarily at her hat. "Look what it does...'She reached up and tapped the hat with her wand. It opened its mouth wide and gave an extremely realistic roar that made everyone in the vicinity jump.'It's good, isn't it?' said Luna happily. 'I wanted to have it chewing up a serpent to represent Slytherin, you know, but there wasn't time. Anyway...good luck, Ronald!”

“Xenophilius Lovegood," he said, extending a hand to Harry. "My daughter and I live over the hill, so kind of the Weasleys to invite us. I think you know my Luna?" he added to Ron."Yes" said Ron. "Isn't she with you?""She lingered in that charming little garden to say hello to the gnomes, such a glorious infestation! How few wizards realize just how much we can learn from the wise little gnomes — or, to give then their correct names, the Gernumbli gardensi.""Ours do know a lot of excellent swear words," said Ron, "but I think Fred and George taught them those.”

“Yeah, but the lost diadem," said Michael Corner, rolling his eyes, "is lost, Luna. That's sort of the point.”

“Hello, Harry!” she said.“Er — my name’s Barny,” said Harry, flummoxed.“Oh, have you changed that too?” she asked brightly.“How did you know — ?”“Oh, just your expression,” she said.Like her father, Luna was wearing bright yellow robes, which she had accessorized with a large sunflower in her hair. Once you got over the brightness of it all, the general effect was quite pleasant. At least there were no radishes dangling from her ears.”

“That's right," said Luna encouragingly, as if they were back in the Room of Requirement and this was simply spell practice for the D.A. "That's right, Harry... come on, think of something happy...""Something happy?" he said, his voice cracked."We're all still here," she whispered, "We're still fighting. Come on, now...”

“I don't think you should be an Auror, Harry," said Luna unexpectedly. Everybody looked at her. "The Aurors are part of the Rotfang Conspiracy, I thought everyone knew that. They're working to bring down the Ministry of Magic from within using a mixture of dark magic and gum disease.”
