Ron shifted his weight back and forth, wondering how he was supposed to approach this. Percy may have been used to Hermione, Ron and Harry sticking their noses into things that didn't necessarily concern them, but he didn't know about the entirety of the DA or the fact that Lavender had shared Penelope's dream connection with the lot of them. How was he supposed to convey his concern without giving that information away? Especially when Lavender had not even given out Percy's name to the DA, only said that it had been a previous boyfriend of hers. It was Ron who had finally made the connection at the Burrow when they were informed that Percy was having the nightmares too.
Maybe Ron should have thought this through better. He should have just had the hit wizards set on Percy in secret and not told him at all. But Percy wasn't stupid, he'd have noticed them and he'd be asking questions. Ron decided to play a card he normally didn't play that often with his family just to get around telling the truth because he didn't want to divulge any information about the DA. It wasn't that he didn't trust Percy, but they had made no agreements about letting any new people know about them so he couldn't betray their trust.
"I can't really comment to you about the investigation, Perce, seeing as how it's newly open and the official investigators haven't even been chosen yet, but I can promise you that I wouldn't be requesting this if I didn't think it was warranted. I just wanted you to know beforehand." Ron took a sip of his tea then to hide the fact that he really hated saying that sort of thing. It sounded so ridiculous to him, but it was the only way he could get himself out of this hole.
