This isn't going to be from your point of view, more from Bill's, but it's still extremely important to the story. Prepare for feels, Dipper-lovers. Sorry in advance! ;)
------------------------------------

As soon as y/n was asleep Bill vansihed and reappeared in front of the Mystery Shack. Y/n had almost discovered that he had regained most of his powers. He wasn't able to transform back into his triangle-like form yet, but he was getting stronger day by day. He didn't want to tell her because he needed a place to stay still. Oh, and because he loved her.

Right now he was on a mission. Get Dipper away from y/n at all costs. Being a dream demon, Bill knew about Dipper's feelings for y/n and was jealous. What if y/n liked Dipper more? He could never live with himself knowing he had the chance to make the girl of his dreams love him stolen from him because of some stupid twelve year old.

Bill crept inside the Mystery Shack, being careful not to make any noise. He entered Dipper and Mabel's room and then entered Dipper's dreams.

In the dreamscape everything was greyscale as usual and it felt so nice to be back in his element. But Bill was too angry to enjoy it. He had to talk to this kid. He watched Dipper open his eyes and immediately jump, startled. "Bill Cipher," Dipper said in a low tone, hate radiating off of him. Bill returned the look but then broke into one of those sideways smiles of his, showing his teeth. "Pine Tree! Just wanted to ask you a quick question."

"Seriously? At like five o'clock in the morning?" As if to prove his point, Dipper let out a big yawn and rubbed his eyes. Bill adjusted his eyepatch and contimued, "my question is why won't you tell y/n how you feel about her?"

If Dipper had been drinking water, this would have been the perfect spit-take moment. "What? How did you--?! No!"

"I know you like her, Pine Tree," Bill said, voice going into that echoy tone, "I know lots of things. I know that you have feelings for her." Dipper sighed and rolled his eyes. "I don't like her, okay? Leave me alone." Bill put a hand on his chin, trying to think of a way to get Dipper to admit it. Having Dipper jealous was the only way this could work. Bill put on another smile and rested against his black cane. "Then I suppose you're fine with me staying at her place? You don't know what goes on at her apartment, do you?" He winked and transported so he was standing next to Dipper, "we're having lots of fun together." That was all he had to say before Dipper broke. "Leave her alone!" He yelled, and Bill grabbed him by the waist and arm and dipped him as if they were dancing. "And we danced together at Pacifica's party," Bill said in a bragging tone, "y/n danced with me, not you." He leaned down so he was almost touching noses with Dipper and smirked, "just like this." He suddenly let go of Dipper, who fell on his butt on the ground but immediately recovered, standing almost as soon as he hit the ground. He bared his teeth, Bill could sense his jealously. Perfect.

"Stay away from y/n!" Dipper announced and Bill clapped his hands together. "Sorry Pine Tree," he sneered, "y/n doesn't know I have most of my powers back. And I don't think she'll ever believe you." He floated back, a few lengths away from Dipper, and tipped his hat, "tough luck, kid. Guess y/n does love me more." He winked and turned to leave, but the sound of Dipper's voice made him turn around again: "Bill, I-I want to make a deal!"
