so i was looking through jorunal 3 deciphering things (like a creep) and i came across the ending page
the code was possibly IMPOSSIBLE to crack but i did it anyway (cuz im a nerd)
i found that at the end of the summer, dipper told ford his real name. are you ready for it?
in journal three, many times dipper goes and writes his name, this happens
m dipper pines. the m is crossed out.
sooo, dippers real name starts with a m
yes. its MASON
MASON PINES!!!
(yes. im not lying)
