Peasy’s Ex control limitations

“I don’t think we need to worry about the exes that much,” said Zzzap.
They all looked at him. “Why not?”
“Well, everything we’ve seen this guy do is either individuals or groups that are all acting the same way, right?”

“I’m betting he’s still got a human brain,” said the wraith. “Or a human mind, at least. I don’t think he can control lots of exes individually. It’s too much input and output for him to handle. Like playing an RTS video game. You can work with one unit, or you can click on a bunch and make them all do the same thing. But it’s impossible to manage more than two or three to do specific tasks.”
