As a result of this, Maxi spends more time socializing with Butters, and neglects his duties, to the point that churchgoers find the church doors locked the following Sunday.
When Mr. Mackey alerts the Denver Archdiocese that "another" priest has disappeared from his parish, the diocese sends a cleanup crew of ordained church officials to thoroughly clean the South Park church, Stan's house, and any other location where Father Maxi has been, in order to remove trace evidence of child molestation, in particular semen.
The cleanup crew take the three boys into the woods, where they have deployed a Zamboni ice resurfacer modified to clean up semen, or "Kumboni".
Surprised, the bishop in charge says that they are not there to kill him, but to cover up his crimes and issue him a transfer to the Maldives, just as the Church has always done with priests accused of child molestation.
The idea of looking back a decade or more to revisit classic South Park episodes is definitely appealing, and hopefully this won't be the last time we see that approach in Season 22.
