Gravity falls theory's and secrets :)

STAN

Omg,is all us gravity falls fans said after "not what he seems" like we won! The Internet got it right. stan had a twin brother, and I haven't heard many theories about him being the author but I was kind of shocked about that. like I was crying tears of joy (not kidding) like MIND BLOWN! But enough of this, ok so all credit to this theory goes to vailskibum94 or 95, his theory states that Stanley (STANS twin brother) made the portal because he believed all that crazy stuff that happens in Gravity falls is because of "extra terrestrial" activity. This is the reason he built the portal, so he could find the reason all of this stuff was happening, so he could reach "aliens" and figure more stuff out.but. instead of aliens... he summoned bill cipher, which is why he said Not to summon bill under NO CIRCUMSTANCES!!!!! But of course, dumb Gideon HAD to summon him like for realz!
Ok whatever I'll deal with Gideon later, ok so back on track. I mean when bill was summoned he did seem to show the Galaxy, I mean this could be what fiddledord was trying to erase from his memory, BILL. but this is only the first half of the theory according to vail. this theory is very well done and has a lot to back it up. well I told you this theory because i would like to talk about it myself. So one thing this theory does not explain is how Stanley got in the portal in the first place. this is MY theory on it. so after bill was summoned Stanley wrote in his book all about him, at first bill seemed fine, he then realized bill was "evil" and had no room left in his journal (which is why he wrote in u.v on the pages) so he jotted it down quickly in u.v writing. him and bill were then, well, enemies since then, Stanley wrote everything he could about bill. bill was then able to somehow get him in the portal and shut it down. I mean he is a magical being and could do this stuff. this would explain why Stan had Togo through so much to put the portal back together. Well, that's just my theory, tell me yours. that's all for now.. not until the next episode comes out (summer) Or util I think of more theories. PEACE
