"Dudley's the cousin," Matt said. "I met him once." He sighed. It was in for a penny, apparently, and in for a few hundredweight, and it was time to agree with Charlie - which meant no secrets. And if Harry was dead, he couldn't exactly be prosecuted.
"Right, so it sounds like the main thing you want from me's whether I noticed anything weird about Harry. But he was using fucking cocaine when I came out here, man, what's not weird about that? You could say I don't have a sense of his baseline behaviour. On the other hand," and he shrugged, "he was clean this year. Around the time we moved. That's not the easiest thing, and he seemed like he never missed it. I chalked it up to a life-altering realisation, you know, when you fucking hit bottom and realise that you can either keep dancing with the bottle or the needle or the powder or what-the-fuck-ever or you can stop, because if you don't, you're going to jail and then to a grave in pretty short order. You have to pick whether you live or die, you know? And I just figured Harry picked living."
"Actually," he added, after a second's reflection, "I figured that was why we moved. But either way - he was clean after. And he was subtle before that - I doubt anyone who didn't live with him had a fucking clue. Other than that, weird shit - the house, of course. That was a whole box of weird shit. And you know what, when he wasn't there, it didn't usually freak out. I mean, sometimes you touch something you think's completely innocent and then it throws a giant hissy fit - I sort of knew that Harry was magic, but sort of not, you see, it was sort of brushed off that he wasn't, but his family was - and you learn to just leave shit alone. But when he was there it would do that weird wailing thing and like that. And sometimes he'd look at you like he was fucking thinking things you didn't want to know, usually about you, but who the fuck am I to judge? Maybe after I'm in a war and kill someone, I can have an opinion on the matter. Until then, not my fucking place, you know? My spidey-sense never said to get the fuck out, and it's not the most reliable thing ever, you know, but it's fucking saved me before, so I listen to it." He thought about that. "By spidey-sense, I mean where you just know shit. You don't know how you know it, but it's like eyes on your back, you know they're there."
