... You can't be serious...... First of all, the thing is quite literally just a
real horror attraction, there is absolutely nothing there that would give someone resistance to fear manip.
Second (can't believe that I really need to explain this but well), the reason of why those things happened to some people when looking at the pokemon episode is because there is a real life condition called
EPILEPSY, specifically speaking in this situation the chapter triggered those with
Photosensitive epilepsy, if you read the
article that you yourself send you can see how is stated:
According to
Kotaku, the reason so many people were affected was because about 1 in 4000 people can suffer photosensitive seizures and with nearly four million people watching the show in Japan, more would likely be affected.
So unless Kenny have Photosensitive epilepsy, which I seriously doubt because otherwise no one would have allowed him to go, he wasn't in danger to suffer those effects.
Also, do to
law people need to have warnings regarding this type of things so the horror attraction isn't even special for having said warning. So please stop with this train of logic to give a character something, because is a quite ignorant argument that ignore how the world work.
