I'm so, so super sorry for not updating sooner. Somehow, someway, my summer decided to go haywire and I didn't get a chance to post for a while with house cleaning and vacationing (aka visiting my hometown for five days). Anyway, here's the next chapter! I'm currently being inspired by music on SoundCloud, so here's the new chapter! (SoundCloud name is Undyne (or Undyne the Undying, I guess)) Also, I've finally figured out the perfect timeline for this in Supernatural. It's between season five episodes 4 ("The End") and 5 (Fallen Idols). So, big thanks to Multiple Fandom Giirl for some much needed inspiration and I guess it's time to dive right in! As usual, thanks for the love and support and I love you all! Thanks and Enjoy!

Motel Room - Later that Day

"And that's how it happened..." Mabel sighed as she finished

The Winchester brothers had sat, listening as she recapped her brother's first encounters with Bill, and how he was possessed only a few days, maybe two weeks, earlier. The brothers were in awe by the power of this thing, yet underwhelmed by his other aspects.

"So you're saying your brother is being possessed by a Dorito?" Dean asked, frowning slightly.

Mabel nodded. "He's pretty cruel, too. Bill likes to experience...human sensations. Last time he possessed Dipper he threw himself down a flight of stairs, slapped himself, and slammed his arm into a drawer full of knives and forks."

Sam felt himself growing even more concerned for Dipper and mortified by Bill's habits as Mabel described them.

The room fell quiet as the boys contemplated how they could get the demon out without killing Dipper. That and Lucifer were heavily pressing on Dean's mind as he heard a faint sound from behind him. Sam stood quickly and Mabel's eyes widened as Dean felt his thoughts fading. A familiar rough voice made him turn to face their new arrival.

"Dean, there is a demon that I've tracked..." The voice, which belonged to the angel Castiel, trailed off as if he realized something.

Dean stood, sensing a new problem had arisen.

"You're already in Gravity Falls," Castiel stated.

Dean sighed and replied, "Thank you, Captain Obvious! What is it? Another problem in this old, shitty town?"

"A demon of unknown origin is attempting to summon Lucifer from a house just outside of the woods. From the looks of it, his host body is only a child."

Dean opened his mouth to speak when a shrill, terrified screech filled the small space.

"Dipper!"

As Dean turned to face Mabel he had realized that, in his rush to leave the house and get her to safety, his journal was missing from under his arm. He'd brought it in case something new showed up or he needed to check something. He looked to Sam as the same realization crossed Sam's eyes.

Dean swore. "That thing took my journal. He must have snatched it when we were getting the hell outta there."

Castiel and Mabel were both in disbelief, though for different reasons, as they each realized what this could mean. Without another word, the three men began getting situated to leave as Mabel stood there, too dumbfounded to leave. Her brother was summoning Satan and she had to follow three strangers to her house to save him and, if they got in the way, Soos, Grunkle Stan, and Wendy.

She tripped over herself as they all filed out, almost without her.

Oh, what have we gotten into, bro bro?

The Mystery Shack

Dipper watched in horror as Bill opened the journal and copied the runes and shapes in various places on the grass before finally forming what seemed to be a runed pentagram. Bill studied the journal that he'd taken from the shorter blond's pocket and began to read an incantation from it.

Dipper gasp as he heard his own voice cal into the seemingly empty yard, "Sdrawkcab ti daer dluoc I taht ysae os si reficuL rof lautir gninommus eht! Et incarnatus est de Deo, angelis et daemonibus de Lucifero dextrae placant, ut vocarent eum reuerterunt. Erigere Lucifero stipendium , pro servitio quod mihi facit."

A swirling vortex seemed to form as an angelic, yet broken, figure rose from the center of the pentagram. The man who stood in front of Bill was blond and average looking. He wore jeans, a plain t-shirt, and a denim jacket over it, and had quite a bit of stubble, though beyond all of that he had a powerful stance. Dipper watched in horror as Bill began to smirk, knowing he had won. Dipper felt hopeless as, for once, there was no way to warn the others.

"H EYA THE RE LU CI! T HE NAM E'S BI LL!"
