TRUST NO ONE

Got super bored at school and worked on my pen and pencil techniques 

Had to spray the darn thing so the pencil lead/graphite wouldn't smear 


I really hope the "trust no one" thing actually does come into play, or brings meaning. 
Like if the "Stanley Theory" (Grunkle Stan's twin) ends up being true where maybe the twins' long lost grandpa was the one who wrote the journals....
if he wrote '"Trust no one" including his sibling Stan.. and you think back to what Bill said...... "Who gives up everything for their dumb sibling?" 
Makes you wonder if Stan betrayed his sibling back then when maybe Bill got involved. 

Betrayals so far: 
-Bill "betrays" the author and Dipper with their deals. 
-Dipper betrays his Grunkle Stan by saying he won't get involved in Supernatural stuff ever again. 
-Stan betrays the twins by not telling them about the portal (he might have betrayed his sibling too... (we know he HAS a sibling since he is a Great UNCLE.) 
-Wendy......? 
-Soos...... (the zombie thing doesn't count).....? 
-The Author........? 
-Robbie betrays or lies to Wendy about the CD song that controls her mind 
-Mabel........? 
-Pacifica's parents lie to her, and she lies to Dipper in the most recent episode about their family curse. 
-The Books ....? 
-Gideon lies and spies on the who town. 

So far the things left to not trust would be Wendy, Soos, the Author(?), Mabel and the books... 
How would they lie? 
(If one of them did lie and I didn't catch it, then let me know and I'll add it) 

Bill Cipher, Dipper Pines, Grunkle Stan Pines, Wendy Corduroy, Soos Ramirez, the author/the Stanley twin (?), Robbie Valentino, Mabel Pines, Pacifica Northwest, and Gideon Gleeful (C) Gravity Falls
