Ron was shaking his head too. He knew that arguing with Percy right now was stupid, but he was going to do it anyway because he couldn't believe that his brother was talking like this. "The dream doesn't matter, Percy! That wasn't you! It's Pandora's memory, it's not even your own! The only reason it happened to be Penelope in the same memory was because the two of you were connected in some way, but those people in that dream weren't actually either of you!"
Ron clenched Percy's upper arms tightly, not willing to let his brother go. He wasn't going to let him get this sort of crazy thought into his head. "The searching doesn't matter, Perce! We don't know if that's why she was killed or not, alright? And it doesn't matter what you said or didn't say, she would have kept digging on her own; he was her brother for Merlin's sake, what else would you expect her to do? We would do the same for our brothers! We have! And we're going to do the same for Harry - but blaming ourselves doesn't find the murderer, Perce! Blaming yourself just lets Pandora go kill more people!"
