Detailed Explanation
This detail haunts me. When someone is sent outside to die, they always clean the sensors—even people who swore they wouldn't. The show reveals why: the suits are designed to show the wearer a beautiful, lush world through the visor. In their final moments, condemned people desperately clean the sensors so those inside can see this "paradise." They don't know they're seeing a hallucination while actually standing in a toxic wasteland. It's the ultimate cruelty—using hope as a weapon, making dissidents participate in their own mythology one last time.
