Some think that there are three authors for the books. This is sort of disproven when it says: REMEMBER trust no one. That might mean He or she wrote  that down in a earlier volume. Some think that stan is the author. I don't think that, but if thats true, i have a theroy. Stan had a wife, and for a while, he was happy. than he researched gravity falls and found monsters. they took his wife, he he turned into a lazy, bitter person. he now dosent belive in monsters. Hes mad at gideon because gideon had something to do with it.
