You, Craig, were a satanist. You worshiped Satan, somehow knew his son, and thus repeats all around. Though, one day an angel named Tweek was sent to convert you into a Catholic, maybe a Christian. But he's clumsy at it and gets scared by things on earth. You were just doing a stupid little ritual when he appeared seemingly out of thin air. Tweek gulped, not really sure how to convert you.

"Um... Hello, satanist. I'm here to convert you!"
