"Why are we out here?" Bill asked curiously as they walked, gaze happily taking in their surroundings "Not that I'm complaining, I'm always up for a walk in the woods."

"I thought we should maybe... Um.. Talk?" he shrugged, huffing out a sigh

"About what?"

Dipper sighed heavily once more

"You know what I'm talking about, Bill." he muttered, shooting an annoyed glare at the demon

"Are you perhaps talking about..." he trailed off, and Dipper suddenly found himself pressed to a tree by the demon, staring up at him in shock while the demon smirked down at him "This?"

Dipper swallowed thickly and nodded his head

"Yeah," he whispered, cheeks flushing a deep red "This."

"What about it?" Bill inquired innocently, and Dipper scowled

"You know what I'm asking, Bill." he growled

"No, I don't think I do"

Dipper could've screamed. Instead he huffed and planted his hands on the demons chest and pushed him back

"Fine." he hissed "Never mind." he turned and began walking away once more "Tell me about Mabel and Pacifica instead."

Bill watched him walk for a moment before sighing and following after, forcing a cheerful expression back onto his features.

"What about them?"

"Are they together?"

"Nope. Blondies parents aren't okay with that."

"Why?" Dipper demanded, clearly annoyed that the Northwest's didn't think his sister was good enough

"Homophobic, she said." Bill informed him, and Dipper looked away when he remembered that his own mother was the very same way "On top of that, it probably has something to do with Mabel not being rich." before Dipper could say a word he pressed on "Don't worry, Pine Tree. They'll work things out."

Dipper grumbled but let it drop.

"Pine Tree, I still think we should talk." Bill tried hours later, annoyed with the silent treatment he was recieiving from the other

"About what? You made it clear earlier theres nothing to-" he broke off when Bill grabbed him and captured his lips once more, pulling the teenager flush against him.

Dipper's hands grasped at the fabric of Bill's shirt, pulling him closer and Bill groaned weakly. They jerked apart when they heard rustling in the bushes, but it turned out to be a gnome. Dipper snorted but kept the distance he had gained from Bill.

"Um." he was quiet for a moment "We should go, it's probably almost time to start our shift."

Bill had to struggle against the urge to strangle the teenager, but he nodded, pursed his lips, and turned to make his way back toward the shack.

"Have a good night!" Dipper called as the final customer left the Mystery Shack

Bill let out an obvious sigh of relief and swung the door shut, clicking the lock into place. He approached Dipper, watching in silence as the teenager emptied the cash register and put the money in the safe. Dipper turned his gaze upon the demon and raised an eyebrow, and Bill raised his in return.

"Are you okay?"

"I'm fine." Dipper replied almost instantly "Why?"

Bill's eyes widened in surprise when he noticed the hairs on the back of Dipper's neck raising defensively. He swallowed thickly and took a deep breath

"I was just curious." he eventually responded, approaching the teenager and placing his hand over Dipper's as he piled up some snow-globes "I'm worried about you."

Dipper's gaze landed on Bill's hand over his, and the hairs on the back of his neck flattened out once more. The teenager visibly relaxed, letting out a deep sigh

"Bill..." he looked up to meet the demon's gaze "I-" he broke off and Bill's eyes widened in alarm when the teenagers pupils abruptly dialated to the point where there was almost no colour left.

"Pine Tree?" he asked worriedly, and the teenager lifted his hand to clutch at his chest, staggering away from Bill and dropping to his knees on the ground with a cry "Pine Tree!" he yelled, dropping beside him and grabbing his shoulders "What's happening?"

"Get away from me!" he choked out, harshly shoving Bill back

The demon grunted as his ass hit the ground, but scrambled back toward the teenager

"Dipper what-" he broke off when Dipper's head shot up, their gazes locking, the teenagers gaze glowing a deep red "Oh no."

"Bill-" he choked and a pained cry escaped him, the arm holding him up giving out and sending him toward the floor

"Pine Tree!" he cried, catching him before he hit the ground and holding him close to his chest, golden eyes round and filled with worry for the teenager "Hey, I need you to breathe!" he cried

Dipper jerked in his arms and lurched up, and Bill couldn't surpress his scream when Dipper's teeth met his neck and sunk through his skin. The teenagers body stiffened as Bill's blood spilled into his mouth, and he jerked backward, falling from Bill's lap and staring at him in horror. Bill gaped mutely at the teenager, lifting a hand to cover his wound, and Dipper scrambled back several feet, eyes fading from red back to their usual green.

"Pine Tree-" he tried, breaking off when Dipper lurched to his feet

"I'm so sorry." he breathed, turning on his heel and taking off, yanking open the door and bolting into the forest

Bill was silent as he watched him go.

It had taken him a while, but eventually bill had pried himself off the floor and healed his wound, feeling as though he was on auto-pilot, horrified in the knowledge that something was indeed wrong with his human, and it was his fault entirely for not keeping him indoors when they first discovered the beast.

He stumbled his way to Dipper's bedroom and undressed, tossing his blood soaked shirt into the laundry hamper and heaving a sigh. After a moment he slid into Dipper's bed and laid back, gaze trained on the ceiling.

It took him mere seconds to decide that he wasn't going to tell anybody what was going on with Dipper, and he was going to do everything in his power to keep Mabel from finding out the truth. As well as that, he was going to find a way to fix him, no matter how long it takes.

He closed his eyes to drift to sleep so he could slip into the Mindscape, feeling suddenly exhausted. He laid in bed for hours, listening to the various sounds the house made, listening as Stanford got up to use the washroom, followed hours later by Mabel using the washroom, and the demon felt guilt settle deep in his stomach.

It wasn't until three in the morning that he began to drift off, only to be disturbed once more. Bill's eyes shot open when he heard a howl echoing from outside.

"Oh, no."
