Ginny Weasley was not having the best day. People still could not get over the previous year. Maybe if she'd hit her head on the table enough times, she'd pass out and be in the Hospital Wing for the rest of the day.
It was only the second day back at Hogwarts of her second year. The first night, there'd been the dementors on the train, she'd made a fool of herself in front of Harry Potter, and gotten teased by a few Slytherins in her year. The day before had been worse. Somebody tripped her in the corridor and she'd fallen onto a blonde girl, both of them spilling their books. Ginny had quickly gathered up her things and sprinted to her next class, her face bright red and burning. This morning, in the girls lavatory, she overheard a few girls insulting her. After they'd left, she'd had to take a few calming breaths and wipe away the tears that had shed (she'd been trying to cry less).
She felt a light tap on her back. "Excuse me," a voice said airily. Ginny turned to snap at whoever it was, sure they were about to tease her boldly, but she was surprised to find the blonde girl from the day before. A blush quickly crept up her neck. "I think this is your book," the girl said politely. Ginny pursed her lips and took the book the girl was holding out.
She looked odd. White blonde hair, light blue eyes that took up most of her face. She had some radishes for earrings and a cork necklace. "May I have my own book back?" Ginny jumped a little. The girl had not sounded irritated or hurtful. She seemed mainly disinterested, as if her mind were in a better, more amazing world.
"Oh, yeah, sure." Ginny pulled her bag up to her side, digging through it for the book. The radish girl sat next to Ginny while she waited, watching Ginny as if she were interesting enough to be given attention. Ginny pulled the book out and held it out for the girl. The girl took the book but did not move to leave.
"You're Ginny Weasley," she said. Some sort of sorrow washed through Ginny.
"Yes, I am."
"You're in my year."
Ginny was surprised, to be honest. She's expected this girl to say something about the Chamber. She guessed the girl looked familiar, but she couldn't remember really seeing her before yesterday. "Er, am I?"
"Yes," the girl said matter-of-factly. "I'm in Ravenclaw, though." She pointed out the crest on her cloak.
"Oh. So you are," Ginny said. She wasn't really sure what to say to... She hadn't said her name yet, had she?
"Yes. 'Wit beyond measure is man's greatest treasure.'"
"Sure. Uh, what was your name again?"
"I'm Luna Lovegood." Luna stuck a small pale hand out. She looked a bit malnourished. For some reason, Ginny felt jealous; she was still trying to lose the last of her baby-fat.
Still, she shook Luna's hand. "Nice to meet you, Luna. I should get to class now..."
"You haven't eaten any breakfast," Luna pointed out. She sounded... Not lecturing or angry like Ron seemed to behave lately (Ginny thought he was acting a bit like Percy). Instead, she sounded worried. But why would this girl be worried about Ginny? They'd only just officially met.
"I'm not hungry," Ginny said. She shrugged it off and stood, slinging her bag over her shoulder. Luna followed Ginny's lead. When Ginny turned her back, Luna stuffed a piece of toast in her robes before walking out of the Great Hall at Ginny's side.
