We can’t be sure of the actual topography of this area, and perhaps we shouldn’t be too concerned. Jon Wick gets away with a lot of stuff and we accept it for what it is. Why should this be different? As with any fire, we should assume that it’s going to spread and pop up in different places. After all, this is an adventure story! Still, I can’t help remarking that those are pretty darned tall people in the background.
Mark might have taken one of those employees along; they are certain to know the layout far better than he could. Then Mark could not only locate and turn off the electricity, but for his second act he could rescue the employee on the way back when that person would be sure to suffer a twisted ankle or something worse. A double-hero trophy for Mark! That might have been too much, though. Perhaps Rivera didn’t want to wander into fantasy.
