ok using my reflexes to screencap the images at the end of Dipper’s Guide to the Unexplained, this is the closest I can give you to the full image. It appears to be Bill Cipher’s eye with two bloody marks crossing it out. Hell if I know what any of that code means, though. Someone should probably get on that.
OK SO the text at the bottom is coded in a Caeser Cipher shifted three letters apparently? so I decoded it and it says:
FROM THE FIRST UNTIL THE LAST SEARCH THE CODES OF CREDITS PAST ONE MEANS ONE SO SEARCH THEM ALL WELCOME TO GRAVITY FALLS
which means that theres clues in previous episodes? and i think i might know what it means so I’ll report back what I find on that front. For now, enjoy part of the mystery being decoded.
FINAL UPDATE ON THIS!!!!! IVE CRACKED THE CODE IN ITS ENTIRETY
ok so the numbers in red are episode numbers, followed by numbers correlating to letters in the messages at the end of previous episodes (with brackets indicating the beginning and end of a word). By matching them up, I got the message:
I WAS SO BLIND HE LIED TO ME THE DARKNESS IS NEAR
as far as I know that’s all to this. It raises more questions than it answers. Still, I’m glad I figured this out.
