Trust me, I live here and I don’t get it either. And when you ask people they’ll tell you they have guns because other people have guns so they need it for protection. So you guys all have guns because you’re scared other people have guns?? Great recipe.

::Spoiler Spoiler:: The theory is, is that when someone goes out to clean, they’re completely stunned in amazement how green and full of “life” outside looks - considering they’ve been seeing a dead world their whole lives within the silo. This is what drives them to clean, they think they need to show everyone what they see in their visor so they clean the sensor.
