He’s coughing a lot, and trying to ditch Cecil. What’s going on? Cecil starts to imagine that Jojo is deathly ill and doesn’t want to tell him. When in reality, Jojo has joined a secret club, and can’t tell Cecil or who knows what will happen? When Cecil returns to Jojo’s house he sees a note tucked under the door. It’s a ransom note! Jojo’s been kidnapped!! Or has he…?
