The first time Neville tried kissing Luna, she didn't even kiss him back, instead she froze, afterwards she asked, "What was that?" And ever since then they had been together. In a sense, anyways. They weren't like a normal couple, they were unique. It was a melding of minds, a bonding of personalities, and an understanding of each other. They talk all the time, there is rarely ever a stretch of silence, unless appropriate. Everything from herbology to wrackspurts, food to thestrals, Diagon Ally shops to school; all mixed into one, never ending, conversation.
After going to a Quidditch game with Ron, to watch Ginny play, because Harry and Hermione were working, the two decided to go to a café.
"What would you have to order, dearies?" the waitress asks as they're sitting down.
"May I have a coffee?" Neville asks, and she nods.
"I would like…oh, you don't have butterbeer—well, a water then," Luna orders, as the waitress looks confused.
Neville taps his fingers against the wood tabletop briefly. "I think the game went well, luckily we caught the Snitch before they were too far ahead of us."
"Yes, yes, but it looked like the Beaters on the other team were suffering from Loser's Lurgy, don't you think?" Luna speculates.
He laughs gently at Luna's logic. "That could be why they barely were able to aim the Bludgers, wouldn't it?" He laughs again and restarts his tapping.
"Maybe I should write a letter to the coach, informing him of his players' illnesses?" She looks out the window of the café as she is speaking. "I don't want any other teammates to be infected with it. It's easy to cure, but albeit even easier to catch."
Neville laughs harder this time, but Luna doesn't seem to notice, because after all this time, he has learned not to question Luna's beliefs. No matter how ridiculous, she believes them and he can't change that.
The waitress comes back with their drinks, asks if they want any food, but they both decline, having eaten so much stadium food during the match. They continue to talk, but this time about Luna's upcoming trip to Norway, on a research trip to find new species of fairy, or at the very least get some samples of the plant life along the sea line, figuring out their potion-making properties. Then the conversation turns to Christmas holiday, which seems to be fast approaching. Neville then invites Luna and her father to his grandmother's for dinner, seeing as it would be just the two of them otherwise.
They step back out into the cold of the night, the brisk air whipping at their faces. Neville reaches out for Luna's hand to hold, not quite finding enough courage to put his arm around her shoulder.
"I'll walk you back to your house then?" he offers, indicating to the darkness.
"If you don't fear the yeti, yes," Luna smiles.
"I think I can fight him off," Neville jokes.
So they apparate to her house, her father working upstairs in his office, most likely writing another Quibbler article.
"I'll come by tomorrow if I can, after work, if I don't have any students in detention."
"That's fine." Luna smiles again. "Well, goodnight, Neville."
He lets go of her hand. "Yes, goodnight, Luna." As he says this, she reaches up on her tiptoes and kisses him. "What was that?" he asks.
