Luna Lovegood.

(A/N: I've always loved Luna's character, especially her ability to make some conclusions and findings immediately, but miss what's right in front of her. I hope I can do her character justice.)

"Luna?"

"Do you need any help with your trunk?" Luna asked, in her characteristic almost-whisper.

"Yeah ... sure." Harry said. How do I respond to this?

Luna's help getting the trunk up the stairs wasn't necessary, since Harry had already levitated it, but it was nice. Harry tapped her wand on the handle of room 12, it instantly opened and beckoned her in. Luna followed.

"So, Harry, why are you at the Leaky Cauldron? I thought you were supposed to be with your relatives?" Luna asked innocently.

"Wha - how?" Harry sputtered. How does she know immediately?

"I thought that you didn't want to be spotted here so I asked to carry your trunk." Luna explained. "My dad and I just came back from looking for Crumple-Horned Snorkacks, but I'd recognize your wackspurt infestation anywhere."

"I thought you were just pulling my leg about those." Harry said. "So, they are real?"

"Crumple-Horned Snorkacks? Oh, yes, they are very real." Wouldn't be Luna without odd creatures.

"Why aren't you asking about - this, Luna?" Harry asked, gesturing at her breasts.

"What, oh your body? What's wrong with it? Oh, you need help with your bra? Nargles giving you trouble?"

"Luna, no. I mean that I wasn't a girl yesterday! I somehow ... changed!" How didn't she notice it?

"Oh, well that makes more sense. Do you need any help with it?"

Harry smiled. "Thank you, Luna, I do need your help."
