Bill Cipher was a dream demon.
This is a fact.
Bill Cipher was a triangle.
This is also a fact.
Other dream demons exist.
And most aren't triangular.
This, too, (unfortunately) is a fact.
Dipper Pines hated Bill Cipher. Mabel Pines also hated Bill Cipher. But with this hate, came a certain amount of curiosity.
And thus, Dipper and Mabel found themselves, in a ring of candles, staring down the strange square before them. He, for the voice could only be male, said his name was Joe Decrypt. Mabel thought he was great.
Dipper didn't trust him.
Not one bit.
Oh, sure! He seemed a lot more trustworthy than Bill, but at least Bill always had a clear reason; he wanted something from you, and he would get it by giving you something.
Joe wasn't like that. He spun all sorts of interesting tales about Bill, and the dreamscape, but how could Dipper be certain they were even true?
Mable, however, enjoyed the dream demon's company, to the point where Dipper felt…jealous.
Not that he would ever admit that, even under torture.
Anyway, Mabel liked Joe, and Joe liked Mabel, and Dipper didn't trust Joe. That's just how things worked. Mabel didn't complain (too much) and Joe didn't really speak with Dipper, and Dipper was just finally getting used to Joe's presence, when Joe just had to stab them all in the back.
With a serrated blade, so to speak.
It was a lazy Sunday afternoon, and Dipper, Mabel and Joe where lounging about the living room.
Grunkle Stan, and Grunkle Ford were out getting milk.
Or something.
Dipper was feeling uncommonly drowsy, and he was beginning to drift off. Mabel was already passed out snoring beside him; he was soon to follow.
Suddenly, he heard Joe's monotone voice chanting the same thing over and over.
In his half asleep state, he couldn't really make out the words; he did, however, understand that it was Latin, and that that was the language used to cast spells. He struggled upright, and saw the green square floating a few inches above Mabel. Her snoring stopped, although he could still see her chest moving with breath.
Then the square was above him, and the world faded to black.
Stanford and Stanley Pines got home that afternoon from purchasing orange juice to find their great-niece and great-nephew in a coma like state on the couch.
Okay, so I don't really know where I'm going with this, but please bear with me and maybe give me suggestions! I am a HUGE fan of Gravity Falls, and this happens to be my first story about it. Enjoy, and no flames please!
