Nathan's just come up from the cellar with a crate of hooch to restock the bar before tonight's opening. Bren's movements catch his attention, and he sets the crate on the floor behind the bar before moving closer to the stage to watch the young man.
He lights a butt and tilts his head back slightly, blowing the smoke out of the corner of his mouth as he watches, figuring he's got few minutes before he needs to get the hooch sorted.
