I figure since they’re already little more than a plot device, might as well cut them down to the minimum necessary to better focus on the characters we should actually be getting to know at that point.
Plus it adds a bit of mystery and a feeling of foreboding to discover Saw’s rebels with our protagonists instead of being shown everything beforehand, especially when we have so little context for them at that stage.
Also, fuck Bor Gullet. Particularly since it doesn’t have any lasting effects on Bodhi beyond his initial confusion in the cell.
