With the young age of the Anti-Christ, this episode appears to be set before the events in "Rapture's Delight", although Jeff Fischer was not present in that previous episode. Also, Father Donovan dies in this episode, yet is alive in "Rapture's Delight".
After Roger sprays Steve with the pesticide, he drops between Roger and Stan. When the camera cuts back from Nemo scaling the fence, Steve is gone. Stan is later surprised to see Steve alive and was unaware of his disappearance.
