Sam watched her move as she took down the painting and put it on the desk, his matchbox still in the palm in his hand. There was something graceful about her movement, a certain kind of fluidity that he wasn't used to. She smiled at him over her shoulder and he swallowed. He folded his fingers around the matchbook, and moved towards the desk as she turned towards him.
"Maybe just supervise," he said, giving her a grin when she asked if he wanted her to do it for him. He looked down at the tacks and then at the painting and wondered how long it'd taken Shannon to work through the canvas. He hesitated in mentioning the hunting knife he still had with him, afraid he'd startle her. If she found out he had it later, however, that would look much worse and he was going to have to sleep sometime. "Uh, actually, I might have something that will help with the cutting," he said, slowly. He crouched down, working his jean leg up. He paused when she thanked him for coming. "Your welcome," he said, a little awkwardly. "Yeah, sorry. I got...held up."
The sudden reminder of Andy's behavior made him shake his head slightly. He would've been here at least a good hour earlier if he hadn't had to stay with Luna. Not that he minded. He didn't want anything to happen to the cheerful blonde, but the fact that Andy had gone off on his own not entirely knowing just how dangerous this place could be was a bit of foolhardiness that he was finding hard to forgive. Andy hadn't exactly made it any easier when he'd made his smart ass comment about being a Winchester. Sam swallowed, the fresh rush of frustration doing more than the red bull to wake him up.
He pulled the knife out of the place it'd been wedged between his sock and shoe and put it on the table, careful to do it in a way that was as non-threatening as possible, with the handle pointing towards her and the blade towards him. He straightened up. "A reward for surviving this morning," he said. "It should come in useful."
