Explaim Mabel, "Ugh.. when will you decide!", Mabel was about to talk until they heard a voice say "RUN!! HE'S GONNA DESTROY EVERYTHING!!", The twins turned around to see what was screaming at their ears but didn't have time to react when they got pull by two persons.

Zero! BILL POV

Hi, my name is Bill Cipher, Me and my brother Will Cipher were just hanging out in the forest while I was reading a 'secret and forbidden book that no one was suppose to find' but right now I am running away from a very angry demon who is trying to kill me because i took this forbidden book.. again,"BILL CIPHER!!!" Screamed the demon, I just laugh and continue to run until I saw two persons in front of us just walking, I yell "RUN!! HE'S GONNA DESTROY EVERYTHING!!" I know this wasn't true, but it made the demon more frustated and more fun for me, I pull one of the person by the wrist and my brother the pull other one, they didn't have time to react and i wanted to laugh so hard but if I do I wouldn't have any breath to run anymore. We took a shortcut and ran into the forest and stop to take our breath back. "Haa.. oof.. sorry about that earlier-- WOW!!" I screamed at the two persons in front of us and back off as they look just as confused as i am,one of them was wearing a Pinetree hat with a dark blue hoodie with jeans and the other one was wearing a sweater with a skirt with jeans under. My brother look up and saw the two persons and screamed a 'AAH!!' before running behind me, "h-how.." I tried to speak and find the right words h-how did they got there ?? He- he was running behind me- NO WAIT, He can read your mind, don't think don't think don't think! I thought until i heard the boy with the Pinetree hat speak "Um.. you.. you okay ?" Do i look okay to you ?? I thought and waited for his response but he never did and look ever more confused. The girl decided to speak "Hi, I'm Mabel ! And this is Dipper my brother, what's your name ?" She bend over to my brother to see a better look on his face but he hid behind me, "I.. I know, you really thought it will work Shooting Star ?", the two persons looks at each other with a shock look on their faces, "B.. Bill ?" The boy speak, "Yeah ?" I respond, their faces look even more shocked than before until the boy speak again with a serious look, "how.. how are you human ? When did you get this human body ?" I wanted to laugh at this stupid question but he had such a serious look on his face, it was cute. "Well.. since i was born why ?", "He always had a human body ? What was the possessing body thing for then ?" I heard the girl whispered to the boy well I couldn't called that whispering since I heard it. "Look, I don't know how you got there but a minute ago you were chasing" I pointed toward the boy, "What ? No ? I was walking until you pull me and my sister here for.. I don't know why" he respond with a serious and confused look until his expression changed like he just realized something.

DIPPER POV

I turned to my sister and grab her shoulders, "Mabel! Do you remember the letter ?" I said with a serious look, "Yes ?" She said confused, I continued "I think someone send us the letter on purpose and transported us into another an interdimensional world dimension ! ..Did i mention dimension by the way ?", "Oooh.." Said Mabel almost impress, I turned to the blond guy, "So you.. you are not a demon ?", he look at me with a shock face and laugh "wha-ahaha.. no ??", "And i suppose the one hiding behind you is not a demon too ?" I pointed toward the person behind the blond guy, "What ? Of course not, this my brother Will" he said pushing the blue haired boy gently in front of us, "H-hi.." Will said with fear in his voice without looking at us. I nod and turned again toward Mabel "This is not our Bill, Mabel." I said, "Oooh, yeah because our Bill doesn't have a brother, good thinking smartass!" Said Mabel while punching my shoulder, "Ouch! What was that for ?" I said, "Meh" She respond, i just stood there with a 'you serious' face, "So.. you guys are not from this world ?" Said the blond guy or Bill, "Nope!" Me and Mabel said in unison. "Huh.." was the only thing he said, So.. i can really be friend with bill.. i thought. We stood there for a moment until we heard a voice, "No sh*t, Pinetree !" A voice came out of nowhere and as we look around to know where it came from, a light appear in front of us and with a 'poof' a really tall blond guy appear wearing a formal yellow uniform with a cane in his hand, he bend toward us with his hat on the other hand "Long time no see, Pinetree" he then wink at me, "Well, I think this is our Bill" Said Mabel and Eww.. was all i could think of.
