Stan, Kenny, Cartman, and Kyle go to Mackey’s office to receive punishment for a prank they pulled. But Mackey is shown to be corrupted. At first, the boys don’t seem scared—only Kyle, who is a bit on alert. It’s when Mackey mutates that the boys truly get scared. But Cartman, trying to add humor to the situation, starts rapping. Kyle interrupts Cartman’s rap, saying it’s not the moment for that. Stan also gets angry at Cartman, while Kenny laughs at the rap Cartman did. Mackey takes advantage of this and attacks Kyle, leaving him semi-corrupted. Stan supports Kyle while Kenny argues with Cartman over what he did, which causes Cartman to leave. Kyle, feeling that his end is near, asks Stan and Kenny to leave and look for Ike. Stan and Kenny flee the place. And Kyle, with sadness, accepts his fate but decides to buy time.

Klye faces Mackey until he can’t go on anymore and ends up fully corrupted.
