Prologue

Sam knew it was stupid before he did it. He knew it was stupid but he was mad and his dad had been riding him all day, hell, all week. He knew it was stupid and he did it anyway, which was why he shouldn't be surprised that he was lying hunched up against the impala's wheel hub staring into the gaping maw of a fucking huge dog and all he could think was that was stupid, well that and Dad's going to kill me and holy shit, look at those teeth. But mostly he was thinking that getting out of the car was the worst idea he'd ever had in his life and then he was wondering why he wasn't dead yet because the dog had lunged forward and Sam hadn't moved but suddenly there was something in between them. There was something in between them and Sam was relieved because, hey, not dead and then he realised that the something was someone and that the someone was Dean and the relief turned into Oh my God I'm so sorry and pleasenopleasenoplease because Dean was on the ground and his arm was in the dog's mouth so his gun was flailing uselessly and then it wasn't his arm in the dog's mouth but his neck and his brother was going to die and it was all Sam's fault for getting out of the fucking car.
