Nightmare Fuel / Active Raid

• Mythos' successful hijacking of most of the Orochi system. Not only does it bring Japan to most of a standstill, but it forces the NPA to declare a state of emergency with a risk of arrest if anyone fails to stay at home after 8 PM.
• The 2nd season gives us a brief moment where Takeru sees the old professor in his rear view mirror, giving him quite the scare. Sure, he calms down when he looks back, sees nobody there, and concludes that he's just imagining things, but after he almost had his body taken over by that guy, it is still very unsettling. Not to mention it could still be a possibility.
