Sorry for bad spelling + grammer!

"Luna?" Harry asked, wondering what Luna was staring at.

"Hmm..." She tore her gaze away from the window.

"What were you staring at?"

Luna turned back to the window. "Erm... nothing..."

"Are you sure?" Harry didn't seem convinced.

"Positive." Luna said in her usual quirky voice. Unsure, Harry left to find Hermione or Ginny; they spent more time with Luna and would have noticed any other peculiar behavior. Glancing back to see if he'd gone, Luna slipped from her window chair and padded towards the fireplace. She muttered a few words and drew a diary from a hidden brick. On the front was Luna's drawing of a Thestral and inside it hid all of Luna's untold secrets.

"Hermione?" Harry charged down the corridor to meet Hermione.

"Yes?" She replied, glancing up from a book.

"Have you noticed Luna acting differently at all?"

"Pfft. Like she doesn't already." Hermione laughed then stopped to Harry's concerned face. "No, why?"

"She was acting differently earlier. I'm just concerned about her." Hermione raised her eyebrow. "She's just a friend. I'm in love with Ginny remember?"

"You two would make a cute couple though." Hermione giggled. "Just saying." She added and hurried away. Harry rolled his eyes and decided to find Ginny. He should just push the thoughts of Luna from his head and enjoy his time with Ginny.

"Hey, Harry." Ginny grinned as she saw him walking towards her. She bit her lip and pushed her hair behind her ear.

"Hey Ginny." Harry muttered. He tried to take back his unenthusiastic tone but failed. "I didn't mean to-"

"Whatever." Ginny whispered and shook the last few minutes from her head. She slipped her hand into Harry's and entwined her fingers with his. "What do you want to do today?"

"Dunno." Harry shrugged his shoulders and sighed. No matter how hard he tried, he couldn't shake the feeling that something was wrong with Luna. To be perfectly honest, he couldn't stop thinking of Luna. It had been like that for a while. Harry tried to think why but this wasn't the time for that. "Go for a walk?" He suggested.

"Sure." Ginny grinned and started walking. "I miss this." She whispered.

"Miss what?"

"Us. Your minds always somewhere else." Ginny rolled her eyes. "Never focused. Well not on us anyway."

"I try to be. I just... Nevermind."

"You just, what?" Ginny's eyes widened and her voice edged louder. "You just what?" She repeated.

"It doesn't matter." Harry muttered. Ginny dropped his hand and began to shout.

"IS THERE SOMEONE ELSE?"

"No, of course not." Ginny looked into his eyes and she knew he was telling the truth.

"What then?" She asked, dropping her tone back to normal.

"I'm just worried. No-one seems to be acting like normal. Hermione has lost her niceness, Ron's just like the living dead and Luna's..." Harry trailed off. "I'm just worried, okay?"

"Hermione has no-one to go back to, no-one to love her. Ron just lost a brother and Luna... I don't know what her problem is."

"He was your brother too." Harry whispered, raising an eyebrow.

"Ron was closer to him.." Ginny snapped, quick to defend herself. Her watch beeped. "I have to go..." She whispered and hurried off. Harry sighed and trudged down the corridor.

I can't remember which brother died + someone's borrowing my book. Which one died?
