My Pinetree~ (Yandere Bill x Dipper)

Chapter 10

It's been a couple of days since Mabel and Dipper had arrived at the Northwest's mansion, and they haven't gotten any trouble with Bill. Currently, Dipper and Mabel were out with Pacifica at Greasy's Diner. They had all ordered pancakes, (since Pacifica's parents gave her enough money to get them all pancakes) and they were talking while waiting for their food.
"So, how was school?" Dipper asked Pacifica.
"It was... okay. What about for the two of you?" she said.
"Wellllll, we did have a couple of friends but, they stopped being friends with us after we told them about our adventures in Gravity Falls," Mabel answered.
"But why?" Pacifica asked.
"Because they thought we were crazy," Dipper answered quickly. Before the three of them could say anymore, Lazy Susan came up to them.
"Here's your panckes!" she said, handing each of them a plate with pancakes. Pacifica thanked her and handed her the money. They thought Lazy Susan had winked, but it was difficult to tell, since one of her eyes was permanently closed, so it just looked like she was blinking. But she took the money and walked away, letting them eat their pancakes in piece. Mabel seemed like she was going to speak up, but she didn't, so instead they just ate their pancakes in peace.
After they had finished their pancakes they got up and left. They were gonna head back to the Northwest Mansion to grab their swimsuits so they could go swimming, but before they got there, the whole world became a grey-scale. Dipper and Mabel silently panicked, while Pacifica looked at them with a confused expression on her face. Until she heard that laugh, it was all too recognizable as Bill Cipher's voice. Dipper looked like he wanted to scream and curl up in a ball, but Mabel hugged him tightly as the dream demon came into view.
"Well well well kids, you honestly thought you could hide from me forever?" Bill asked. Dipper and Mabel didn't say anything, while Pacifica stared up at him. She was about to scream, but Bill snapped his fingers. When she tried to speak, no words came. She didn't have her voice, she couldn't speak, she couldn't scream, and it scared her. Dipper, who had stopped hugging Mabel a couple of seconds ago, came up beside her.
"Stand behind me," he whispered to her, hoping that Bill didn't hear. He didn't appear to as Pacifica got behind Dipper.
"Listen Pinetree, I gave you a warning, didn't I?" Bill asked.
"Maybe so Bill, but I was not going to stay in the shack with you taking care of us!" Dipper answered. Bill narrowed his eye, and snapped his fingers. Mabel screamed and pointed at Pacifica. Dipper quickly turned around to look at her, but she appeared to be choking, with her hands on her neck and trying to gasp in air. Dipper could do nothing but watch as she fell to the ground, dead. Tears escaped from his eyes, and he glared at Bill.
"Why did you kill her?!" Dipper screamed at the demon.
"Don't you remember my warning?" Bill asked while twirling his cane. Dipper's teeth clenched, and his hands turned into fists. Mabel hugged Dipper again, scared. Dipper hugged her back, still glaring at Bill. Bill laughed and spoke up.
"Now then, let the real fun begin," he said, then snapped his fingers. Dipper's eyes widened for a split second, then the two of them disappeared.
