Look, It is impossible for Stan to be one of the offers because it says in the piliot when Dipper finds the first book "Its been 6 years since I've began studying the strange phenomenon of Gravity Falls" And On the Head Hunters episode the Wax Figures say that Stan Bought him 10 years ago, Obviously he is either blind and knows nothing about it, or knows about things but is not an enemy, remember Stan Sent Dipper to fin the book on PURPOSE. If there is another enemy it would have to be a surprise, like Wendy. It is shown in The Gobblewonker that Stan does care about Dipper and Mable and Is Friends with Soos and he would'nt do anything to hurt them. Now the Mysteryman MIGHT be a time traveler, but is most likely to be the author of the books studying Dipper, he must have a connection with dipper, He stole a shoe like Dipper's, and he ALWAYS appears somewear close to Dipper.
