It's not like they're supporting demonic rituals, Lila!
In fact, if this show could teach you anything, it's to avoid demonic rituals!
The entire show is about how Bill has morphed they're lives, intentionally, and unintenionally, and they have to save the entire city and defeat him!
at least, the main gist of the storyline.
And also about how family is always the best, that too.
