"That makes it worse, Luna. He saw an unknown spell and decided to experiment, on Draco!" Astoria frowned. "Potter thinks he knows best, but he doesn't. Experiments can be really dangerous. I mean, you know-"
Luna reared back, as if smacked.
Astoria's eyes widdened, "I'm sorry, I didn't-she was your mother, I shouldn't have-"
Luna shook her head. "No, you're right."
"It's just, curses aren't a joke."
"Oh! Your bloodline?"
A nod. "...we think I inherited it."
