I'm assuming that this void comes from, like, an obsessive need for validation? I hope they don't have to all die or anything, they're just little guys..... They don't seem like they want to hurt anyone... they're just overly enthusiastic....
Last 2 chapters have been great! But I have to say sage is getting pretty annoying especially after being hypocrite about the stalking. We need one other person to find out Mars' identity so isn't just Sage all the time.
