Exe idea

Slonic has severe insomnia and sleep deprivation due to something and it's gotten so bad he has started to hallucinate innocent mobians as badnicks. He'll "destroy" them when in reality he's just killing a civilian without realizing it.

Trails, his best friend who is also suffering from some insomnia but not as severe, needs to chase him down and give him special sleeping pills. He has to be careful though, if he gets to close to Slonic, he might be mistaken for a badnick.
