No one's POV

"Ok so we know that this machine takes you to a opposite version of your dimension witch can only mean that if we go through the portal in this dimension we would to the opposite of our dimension not yours dipper so what do we do then."mabie said.
"Well I guess we should take a chance and go into the portal but we need someone to start the portal again ,do any of you 2 no how to start the portal?"dipper said.
"Well I have a little of knowledge scence uncle Ford gave me some lessons but he said it was dangerous to start it, are u sure u want to do this?"mabie said a little shaky.
"Yes and I will not change my mind at all" dipper said
"Ok I will start it dip, I still think that name is so stupid , can you please take care of this dipper"mabie said.
"Mabie you know I'm not a baby right?"dipper said.
"You seem like it with those noodle arms no offense" Mabie said.
"Sigh. Non taken"dipper said.
"Welp this just ruined my brain this is just too nerdy I can't be live I'm a nerd in the other dimension it's just too I don't know as my brain it hurts I will go get smile dip!" Dip said really energetic.
"I don't want to see myself get dunk because of rot candy that has expired a long time ago" dipper said.
"Pff I don't get drunk,I only see a dog that offers his paws all the time and I eat it with pleasure and I fly with aoshima, and it's better candy than the summerween stricter you know" dip said.
Every thing started to float that meant Mabie had finally opens the portal again this was dippers chance to see his real twin sister he floated to the vending machine to go to the lab and behind came dip what seemed jump floating and pretending he had fairy wings then he started to dance the whip in mid air dipper decide that when he get home he would use the Blonde Eye's ray thingy to forget that they finally got downstairs he saw two people he wouldn't have expected to see and then the portal seemed unstable and there was a really bright light suddenly everything went black and everyone was falling.

Hmm anyone guess who the people are and what is happening in this scene? Will dipper go back home? When is Bill going to appear again? hint hint I'm sorry I took days to update but here is kinda a filler chapter next one will be more humored and filled with secrets and remember to burry your gold people the group will need it
