Dennis Werner - a tall man of mixed German and Native American descent, as well as the night supervisor - sat in the back of the van, reading the book he'd brought along for the ride - "Pushing Ice", by Alastair Reynolds, to be precise. Always a fairly quiet man, he had barely paid any attention to his comrades' conversations. However, from time to time, he'd look up from his book, just to see what his fellows were up to. On the most recent "look-up", he saw Henry spit into his bottle, before drinking the water again. That sight had made Dennis grimace - few things had managed to get that reaction from him, but this was definitely one of them.
"For fuck's sake, man, how can you DO that?" he asked.
