I couldn't come up with a way to get rid of this mark so far. Neither could Ford. And the others didn't know. Anyway, I went into the bathroom, and locked the door behind me befor finishing my business and washing my hands. "Hey, kid." I jumped, too scared to scream, and looked around. But I didn't see anyone. "W-whos there?" "What? Don't recognize my voice, Pinetree?" "Bill! What do you want?" I asked, scowling. "Oh, nothing much. I only want to be summoned." I shook my head. "Well, that's not going to happen!" His voice sounded like it was right next to my ear, low and almost a growl. "You seem so sure about that. But remember who your dealing with." Before I could answer, a knock sounded. "Hey, whoever's in there better hurry, cause I gotta use the John." "One minute, Stan!" I told him, splashing water on my face, then drying it off, and then making my way to my bed. But he caught my wrist. "Hey. Kid, what's this?" I tried to take my hand back. "I-um, it's nothing, Grunkle Stan. I promise!" "Wait..." He then looked into my eyes, and I looked away, down to the floor. I couldn't look him in the eyes. "Isn't this-" "The summoning circle for Bill Cipher? Yes." I answered his question, my eyes shut tight. I told him about what had happened during my research-and then realized his mark was now glowing. "And anytime someone in the circle touches me, it brings Bill a step closer to coming back." "Hmm. Does anyone else know?" "Ford does." I told him. "So your sister doesn't. Do you, uhm, wanna tell her, or am I telling her?" "No, I'll tell her." And I went to find my twin sister.
