Wayne knows why they're having termite problems, too. When the developers cleared the land for building, they set all the citrus trees on fire and then plowed them under. All that wood underground attracts termites. When they come to the surface to find water, they also find houses to chew on.
Wayne drops Paul off at home, and starts spraying the insecticide.
Paul sees Erik and Arthur practicing in the backyard, and they don't stop even when white clouds of pesticide start swirling around them.
Seeing them coming in and out of focus in the cloud sets Paul off on another one of his flashbacks.
The whole family was in their backyard in Huntsville, when Paul was in kindergarten. His parents were standing in front of him, and his dad was making Erik move around Paul in a circle, to test his peripheral vision.
Paul kept saying that he couldn't see Erik, no matter where he moved behind him to either side.
Suddenly, Paul felt Erik's breath on his neck, and screamed. Erik had snuck up on him.
Mr. Fisher yelled at Erik, but their parents both ignored Paul as he started crying.
They were arguing about his eyes, until finally, his mom insisted that she was taking him to get new glasses.
That's when Paul got his super thick glasses. Now that his flashback's over, he realizes that that was also when he started to see Erik for what he really was.
