“Yes, it was rather horrible,” said Luna conversationally. “I still feel very sad about it sometimes. But I’ve still got Dad. And anyway, it’s not as though I’ll never see Mum again, is it?”
“Er — isn’t it?” said Harry uncertainly.
She shook her head in disbelief. “Oh, come on. You heard them, just behind the veil, didn’t you?”
“You mean . . .”
“In that room with the archway. They were just lurking out of sight, that’s all. You heard them.”
They looked at each other. Luna was smiling slightly. Harry did not know what to say, or to think. Luna believed so many extraordinary things . . . yet he had been sure he had heard voices behind the veil too. . . .
“Are you sure you don’t want me to help you look for your stuff?” he said.
“Oh no,” said Luna. “No, I think I’ll just go down and have some pudding and wait for it all to turn up. . . . It always does in the end. . . . Well, have a nice holiday, Harry.”
“Yeah . . . yeah, you too.”
She walked away from him, and as he watched her go, he found that the terrible weight in his stomach seemed to have lessened slightly.
