Hey imagine if there was a darkness that once you enter will slowly take and replace all the people around you. There is absolutely no difference in their behavior except for their lack of fear for death because the replacers aren't capable of dying since they are part of the darkness. They think they are still human even though they've been replaced and will adamantly deny being replaced. the more the imposter has people believing its words, the sooner the real body dies.
This would make a really funny experience for agent choi and agent bronze if they enter with grapes. Just saying.
