Bill Cipher is the least of their worries as Dipper and Mabel do the family business. They thought that they were on an ordinary case, but it blossoms into something else. With a new threat rising, they must find a way to save each other. Angst-y, with a chance of tears. Character death. Rating because of language, killing, mentions of suicide and cutting, and possession.
