Kind blah chapter. Tell me if I should change it.

"Stan?" Dipper gasped. He saw the old man walk over in a hazmat suit pulling buckets of toxic waste. The man immediately stopped when he saw the twins and Pacifica (he didn't know it was Bill) next to a broken window.
"Oh. This is rich," Bill said aloud.
Pacifica was still mourning about her 'perfect' hair being ruined forever, to even notice her arm was bleeding slightly.
"Stan? What are you doing?" Dipper asked, his voice cracking twice. Mabel bit her lip, fighting back the tears.
"Listen. All this it's-"
"For an evil plot?! Are you working for Bill or something, because I think you're who the author told me not to trust!" Stan was took aback by his great nephew's outburst, while Bifica slowly inched his way toward the grappling hook that was now on the ground.
"Listen kid. Y-you don't understand," Stan stuttered.
"Of course I don't because you're a lier!" Dipper shouted ignoring Bifica all together. Bill smirked as his fingers wrapped around the grappling hook. Mabel's vision was impaired by the tears streaming down her face. Bill looked up at her, the barrel of the grappling hook pointed at Stan and saw how upset the child was. Dipper looked back and saw the pixie cut blonde froze in a decision. Pacifica was talking to Bill 'getting into his mind' trying to stop him.
"No. Quiet. It's what I have to do." Bill demanded out loud to Pacifica.
"No puppet strings have to hold you down, Bill," she whispered.
"You don't understand who I'm working for, Northwest. I'm not highest up you know." Dipper looked at Bill.
"You're not?"
"You think I want to do this? This was how I, how all people where I lived were raised. To serve the ultimate puppet master." The world turned gray and Bill was thrown out of Pacifica. Dipper and Mabel hid behind a bush as the triangle cowered in fear as a large portal, revealing space, appeared.
"You dare tell of my plans!?" Bill looked down. Dipper and Mabel couldn't see anything in the portal.
"You're a disgrace to all and a failure in what I created you to do!" The voice boomed. "I'm worried about what you would've done if I hadn't intervened." Dipper knew that voice but he couldn't pinpoint it. Suddenly it hit him.

"Time Baby." Dipper muttered. "No wonder Bill hates him. He's Bill's puppet master. And Time Baby is worried about Bill revealing his true plans," Dipper gasped.
