Yall know Carrie? The Stephen king book and movie that is a classic and that most people don't know has a musical. In general i think it would be a cool dynamic of Butters mom and Butters to live by themselves, (dad left after butters was born in this au) and his mom is very Christian and just wants to go to prom with Kenny here is my note- that I wrote at 12 am and was obviously loopy lol:

YES YES YES BUTTERS AND HIS MOM ARE CARRIE AND HER MOM i remember how those boys would dance
