Back To Gravity Falls: Beware the Beast (Multiverse Crossover)

A Fight Among Titans

Gideon was standing alone in the kitchen, eyes watching out the back window. That familiar weight of dread had settled again in his throat and stomach, threatening bile from the stress. His fingers twitched, somewhere between making a fist and scratching at the air beside his legs. His face was white as a sheet, waiting on Mabel. He hadn't given any outright indication for what little he had participated in the dinner, but he wanted whatever "test" Mabel had planned to end.

His mind was teetering from the concern of himself being in danger and the horror of the possibility of him bringing some scent or trail along with him for this new manifestation of Bill-- the beast known as Xolotl-- to follow. He listened for her footsteps with fearful anticipation, soon met by Mabel's voice.

"Well aren't you an eager beaver," Mabel said mirthlessly, shifting her weight from foot to foot.

Gideon turned, licking his lips, "Just get it over with, will you?"

"Fair warning, it's probably going to hurt," Mabel admitted, pulling a piece of paper from her pocket.

"I don't care," Gideon sighed, eyes welling up with tears as he crossed his arms defensively over his chest.

Mabel had never seen him look so vulnerable and scared, she remembered their age difference and swallowed her shame, "This spell should be able to tell if there's still a connection, it reveals the source of a recent possession."

"Don't explain, just get on with it!" Gideon snapped, hugging himself.

"Right," Mabel sighed irritably, unfolding the paper and chanting, "Videntis omnium, Magister mentium, Magnesium ad hominem--"

"This sounds really made up," Gideon snides, chuckling despite himself.

"All language is made up you idiot, it was in Ford's journal, let me finish," Mabel quipped, only half in meanness.

Mabel raised her voice as she shouted the last of the incantation, "MAGISTER MENTIUM, MAGISTER MENTIUM, MAGISTER MENT--!"

Gideon fell to the floor, sprawled in pain as his eyes shined yellow with beacons like spotlights.

"Mabel, stop!" Coraline yelled, running into the scene with all but Greg in tow, "You don't know what you're doing!"

"Two more syllables! Two more and we'll know for sure if Bill can't track us!" Mabel cried out, worried that time would lapse before she could finish.

"You're leading him right to us!" Coraline shouted. "I saw it in a vision just now! How could you be so thoughtless!"

Mabel looked around, finding accusatory stares from everyone but Gideon who was groaning in pain on the floor, and she tossed the paper in which she had transcribed the spell onto the table.

"I'm sorry," Mabel closed her eyes and gritted her teeth. "What now?"

"We don't finish it, let Gideon settle, and we hope it didn't work." Coraline sighed, visibly frustrated.

Mabel swallowed thickly, "I've ruined things, haven't I?"

"Not much more than they were already," Dipper grunted, looking out the window and watched the treeline with lethargy. "Alright, it's almost dark anyway. Let's get this ball rolling and get Wybie outside with Tezzy while we all prepare for the worst."

"You," he looked back at his sister with no anger, only disappointment. "Watch over Gideon. You did this, you fix it. Take him to the cellar, I saw the door by the dining room. Wirt, you lock up the house with Greg. The rest of us..."

Dipper scrunched his eyes as though he couldn't be any more miserable and huffed, "The rest of us, hope we all make it out of this."

The group disbanded, Mabel kneeling over Gideon whispered with remorse, "I hope you can accept my apology for this."
