Chapter 4: What is it?

(I drew the picture, and there's more in it but I can't show you guys yet;))
Reader/Bill POV

Mabel stared at Bill, eyes wide and mouth agape, "Dipper? What did you do?"

"Bill saved you, Mabel, you're alive because of him." Dipper said, smiling.

Bill didn't feel right, something was off.

Mabel's heart monitor sped up, and her face turned pale.

Dipper stood up and rubbed his eyes furiously.

"Dipper what's wrong?" Bill asked, suddenly concerned.

Dipper screamed in agony and he held his face in his hands, still helplessly scratching at his eyes.

Mabel fell back on her bed, black slime once agin returning to the corners of her mouth.

Bill looked back at Dipper, his eyes were gushing the black slime. Bill stumbled backwards.

Mabel and Dipper screamed at the same time. And then it stopped as Dipper fell to the ground, eyes wide open as tears formed in them.

Mabel stayed silent.

Bill saw a button on Mabel's bed that said the word 'NURSE/EMERGENCY' he frantically pressed it.

A group of three nurses barged into the room, "What happened?!"

Bill looked at them shocked, fumbling to say words.

The nurses pushed him out of the way, checking the vitals of Dipper, unconscious on the floor. He saw the black slime come off of Mabel's bed and begin to form a being.

"You must be the famous Bill Cipher. How pleasant to meet your company. And don't worry about the two unconscious humans behind us, I just gave them a little bit of nightmare fuel, maybe a vision." They said.

Bill looked at the being, "what are you?"

"I am Cix, the demon of unholy nightmares and visions." They smirked. "Kinda like you, Cipher, just not as powerful, and you control all things chaotic! That must be quite the job, running the nightmare realm!"

Bill clenched his fists, "You must be new..."

Cix laughed, "Yes, in fact I am! How kind of you to notice! But I wasn't made serve you."

"Then who?" Bill asked the other demon.

"Simply put, I serve myself. I don't follow a commander's rules. I was made to spread terror through anyone I could find." Cix replied giggling. "And my strength is nothing compared to yours or any other demon barely surviving without you in the nightmare realm."

Bill raised his eyebrow, "Barely surviving?"

Cix just laughed and flowed back into Mabel's body, entering her mouth.

Bill opened his eye to a bright light being shined in it.

"Sir are you ok?!" A nurse asked him.

Bill realized he was lying on the floor, "yeah. I'm fine." He swatted the nurse away, and looked over to see Dipper and Mabel in perfect condition, Dipper on a chair and Mabel asleep on her bed. "How long was I out?"
