When the pandemic began, I wondered what Giovanni would do for his employees. The ones that have desk jobs might do alright, but then there's still countless field agents that are at risk, and he can't just ignore the problem or force them to keep working, because that's an awful lot of people that would be willing to take a plea deal in court in order to take him down if he screws them over. I'd be willing to bet that these two somehow managed to make those masks, considering everything else they've managed to build.
