"Mabel? Where are you?" Dipper pushed a bush on his way to the clearing where he thought he had seen something yellow from the corner of the eye. Frowning, he realized that the forest was unusually quiet for such a lovely mid summer afternoon and not even a chirp could be heard and there wasn't any sound from the gnomes.

Mabel had disappeared that morning saying something about a walk, her sweater half down and with no shoes at all (Ford managed to stop her just in time to get her some sandals), that no one found weird that she only came back for lunch, out of breath and a few new scratches probably from the stray tree branches in the forest.

To Dipper this wasn't so normal. It's true that his sister is known for jumping into the weirdest and craziest adventures, but this time it's been days of vanishing into the forest. Days!

"Mabel!", shouted when he caught a glimpse of brown hair in the middle of the clearing.

He approached the silent figure of his sister with a smile on his face even when she couldn't see it with her back to him. He put a hand on her shoulder and gently turned her. But he froze in the spot because, instead of warm hazel eyes like his own, he saw bright yellow eyes with a slightly long pupil. Even if the little smile wasn't there, he knew who this was.

Bill Cipher.

Then he blinked and everything turned back to normal as if time froze with him and now it was flowing again, because he could now hear the quiet chirping in the distance and a few animals behind the trees. Mabel was staring at him, frowning.

"Everything ok, Dip Dip?".

With the heart beating a mile an hour, Dipper looked around but in that clearing there was no sign of the evil triangle that still plagued his nightmares.
