One of the more confusing subplots of the show is the underground organ harvesting business that some of the guards participate in. The show doesn't provide many answers about how long the operation has been going on and where exactly the organs are being sold, but those aren't even the biggest questions viewers have. Like, how did the guards know a doctor would be present at the games to help with the harvesting? How long does the organ harvesting business last, especially if they rely on competitors to do the dirty work? What happens if the guards don't have access to a doctor with the experience to properly harvest the organs?
