He couldn't imagine what it would be like to be told that Percy was going to die, that he was, more or less, already dead, and he didn't want to imagine the pain it had caused Percy to hear it about him. Nodding slightly, he ran his fingers through Percy's hair, ignoring the small stabs at his shoulder when he did.
'I'll be more careful, I promise I will. A bit more like the Slytherin I am and a little less Gryffindorish,' he said with a smirk, smiling again at Percy's comment.
He couldn't help but to be nervous when Percy answered his question though, because with the answer came the knowledge that he would have to tell. There was no way around it, and he couldn't be sure how Percy would take it.
'There is really only one,' he said closing his eyes, fighting back the part of him that told him that Ginny was smart enough to keep her mouth shut. She wasn't the only one who knew about them though, and well...no he'd promised. 'You actually once touched on it, before, when we were just friends. Told me you'd rather not know if it was so,' he said. 'But I guess it is the one person who would bother you.'
Opening up, he looked at him, facing whatever reaction there would be. 'I used to have sex with Ginny from time to time,' he finally just said, more or less holding his breath in wait of Percy's reaction.
