Andy hadn't slept terribly well the previous night, either. Mainly, because he felt his space was being invaded and, of course it had to be a Winchester. The suave, rogueish, pretty boy Winchester. Not that Sam wasn't a pretty boy, because as far as Andy was concerned, he sort of was, but Andy could tell just by looking at Dean that he had far more notches on his bedpost than Sam probably did. Not that he thought a lot about it, but Andy was a judge 'em by their cover type, even if he didn't really like to admit it out loud.
He stayed awake when Dean had passed out - useless fuck, some Winchester he was - so that he could keep watch for Luna and the sun was barely up when he'd leaned his head back against the side of it, staring at the ceiling. He'd sort of zoned out by the time Sam had come in and then Andy had become the useless fuck, because he hadn't heard Sam approach at all and startled slightly at the sound of the other man's voice.
"Hey," he replied, recovering, and tipped his chin up with acknowledgement. "Have at, man," he replied.
