"A body, huh?" Bill said. "You got yourself a deal, but you gotta do something for me. We'll discuss details later."
Girlie gave him a disapproving look. Her "This is not good" siren was going on inside her head like crazy. They had failed her with Gideon, so in retrospect, it may have just been her trust issues firing up to compensate for the lack of good judgment she had used earlier.
Then again, everything about him, his one eye, his triangular shape, the way he floated midair, just screamed, "Demon." But the way Prez looked at him, you'd have thought Bill Cipher came from the sky and gave her Nutella and a TARDIS.
He just didn't seem like someone to trust with something as important as hiding a body of psychopath. He didn't even seem like someone to trust with hiding a Tootsie Roll.
As though he read her mind, Bill said, "You can trust me kid! I got this."
Girlie still wasn't willing. She knew Bill wasn't gonna string Gideon up from a flagpole with the words, "Prez and Girlie Appleshine" carved into him, but she had an itching feeling that he would do something that would eventually lead to the girls getting arrested.
"If you don't believe me, help with the hiding of the body."
"You expect an all-knowing, all-powerful, mind demon to be able to do it all by himself?"
"Do you really want the answer to that?"
"Be here tomorrow," Bill ordered, rudely.
"Yeah, yeah, yeah," Girlie answered, unaffected. She hoped he caught on to that.
Prez and Girlie walked in the shack and up the stairs to the attic. They opened the door, and Girlie was immediately pelted with a ton of marshmallows and one dirty sock. But before she could react, Dipper and Mabel yanked the Appleshine sisters in and locked the door.
"You threw your sock at me?" Girlie asked in disbelief.
"We thought you were Gideon," Dipper explained. "Now, will you tell Mabel that shooting him with marshmallows won't stop him?"
Technically anything can stop him. He's dead.
"We thought something happened to you," Mabel said. "We thought Gideon got you."
He did. But he won't get anyone again.
"Why are you two so quiet?"
"What's with the journal?" Girlie finally asked.
"Gideon did catch up with us, or me anyway. Why does he want the journal?"
"I wouldn't know." Dipper looked worried. "Mabel, tell Grunkle Stan there is someone trying to sneak a ladder in."
"What does that have to do with anything?" Prez muttered.
Mabel lowered her voice, probably trying to do an impression. " 'You know, studies show that keeping a ladder inside the house is more dangerous than a loaded gun. That's why I own ten guns. In case some maniac tries to sneak in a ladder!' "
"Your great uncle is weird. Besides you don't have to worry about Gideon."
"Of course, we do!"
Prez explained all about how she saved Girlie by doing the unspeakable.
"This is bad. You killed him?"
"He was going to kill Girlie! It was an accident. I only meant to knock him out."
"I - Did you get rid of the body?" Dipper took off his hat and ruffled his hair.
"Bill is going to help us tomorrow."
Mabel stuttered, "B - B - B - Bill? You - You mean Bill Cipher?"
"What is wrong with you people?" Dipper yelled. He pulled Journal 3 out his pillowcase and flipped through it. He halted at a page that had Bill drawn in black. There was a red substance that splattered the page. Girlie pretended it was cherry Kool-Aid, not allowing her mind to wander to other possibilities. The think that really caught here attention was "DO NO SUMMON AT ALL COSTS!"
"We dealt with Bill. He is insane! He thinks just about everything is amusing. He may come off as just an annoying demon, but he's much worse. When he's mad... he'll destroy everything."
"Bit dramatic, right?" Prez said.
Girlie answered, "I think he's telling the truth."
