Here is my theory, which may confuse you guys so read carefully. Firstly, in episode 1, remember what Dipper read in the journal? “It’s hard to believe it’s been 6 years since I began studying the strange and wonder secrets of Gravity Falls”. By the time the author wrote the 3rd volume, he had been in GF for 6 years. So I can assume that: After six years in GF, the author mysteriously disappeared. 10 or 15 years later (since the journal is quite old, I think it’s an acceptable period of time) Dipper came and found the book.
Okay, now move to the confusing part of my theory. Everyone here may have read the theory that Stan has a secret twin, right? Now take a look at these pictures from Stand’s memories (Episode 19). I’m pretty sure it’s Stan because these things were in his memories.
Young Stan, probably teenage Stan. See that girl? She is Carla “Hot Pants” McCorkle. Check the image below and tell if you find any difference. Notice that Stan was wearing the thin rim glasses.
Stan grew up. See Carla? She was saved by him when he was a teen and they were still hanging out. So Stan should be around 20 at that time. Notice that his shaved beard. And no glasses. Hm, I can’t seem to explain this detail so let’s skip it.
An older Stan. Base on his wrinkle, I guess he was 30-35. But still notice the shaved beard. No glasses again.
Stan was in prison. Maybe because he sold Stan Vac, LOL. He still had shaved beard and thin rim glasses. At this time, he was probably 40-45 since he look quite 60 or older for now.
Stan opened the wax museum “many years ago”. Since Sherlock Holmes and other wax men “have been waiting 10 years to get our revenge on Stan”, we can assume that Stan has been in GF for around 15-20 years.
Alright, so we have a brief story about Stan’s life. He met Carla when he was young and later on, he was sent to prison for selling Stan Vac. He may have come to GF after being free and then opened the wax museum. After shutting down his first business, he turned the shack into the Mystery Shack and has run it until now. But the important thing is that Stan has just been in GF for around 15-20 years.
Now, take a look at this
Everyone agree this is Stanley, Standford’s secret twin, right? I also agree with that theory. Look, no beard, thin rim glasses. I guess Standley and Standford used to wear same glasses but Standford later changed his glasses. That’s why the glasses symbol on Bill’s circle does not symbolize him. Okay, enough with the glasses. Here is my theory. See how old Stanley was? He was actually quite young, maybe 30 at that time, which means he has been in GF even longer than Stan and the author. Who knows, he might be the founder of GF secret society. After Stanford came, they have been searching for something in GF but then Standley disappeared. And now his brother is trying to save him by re-building the portal. But the question is: what did Stanley do while he was in GF?
See this in Carpet Diem? Have you ever asked yourselves: Why “Experiment 78”? What about the previous experiments? Stanley’s room doesn’t seem to have any place to hide them all. So my theory is that it was Stanley’s experiments that caused the paranormal in GF. Since he was quite smart to make this carpet, he may also have made the crystals that change height in episode 11, the powerful game machine in episode 10 or the bottomless pit in episode 14….. Maybe these experiments were accidently spread around the town, caused the paranormal and resulted in Stanley’s disappearance. Years later, when the author came, he and Stanford have been working on the portal to save Stanley. However the author also disappeared and it’s up to Stan to find the books to save them.
So, it was quite a long theory. Thanks for your patience :)
