Neville and Luna hang out.
Neville couldn't believe how nervous he was. This was Luna. One of his dearest friends. But this wasn't them being friends. Of course, that was part of it. Neville could never imagine himself with someone that wasn't a friend. Telling himself that he needed to calm down, he took a series of deep breaths. He knew what his plan for today was. He was going to show her what he'd found - and hope that she liked it as much as she thought he might. And, well, he was going to ask her to be his girlfriend. The most she could do was say no, right? And he knew that no matter what, Luna wouldn't stop being his friend. She wasn't like that.
Walking into the Great Hall, his stomach had been too nervous to eat. This had been one heck of a day. He'd spent part of the day with Snape - they'd worked on memory potions. Seeing Luna, he smiled and waved. He sat at the end of the Gryffindor table, figuring that when she was finished she'd join him.
