It's the meaning of life, the universe, and everything? [dipper no one gets your nerd jokes. also dipper read the hitchhiker's guide to the galaxy if i say he did @ alex hirsch fight me] I've never actually heard of 42 being used in demon rituals or anything like that. It's an even and pronic number, but I get the feeling math is probably not relevant in this case. More than that, they need 39 people dead, since three people have to live to the end, right? That's even more of a random number.

[please don't let him math i am not actually good at math]
