Dipper's POV
Me and Bill is just in the attic...since Y/n and Mabel went out to the woods to have some girl time...I was reading my Journal...and Bill is stalking Y/n's phone for some reason which she forgot to bring
"Bill...your sick man!" I told him
"Psh mind your own bizz,Dipper" Bill told me just scrolling down on y/n's phone
"What are you doing there anyways?" I asked and walked towards him
"Looking at her selfies,reading massages,reading her phone diary and checking out this thing called facebook" Bill said totally focused on y/n's phone
"Can i see?" I said and looked at y/n's phone...and Bill is on y/n's profile on facebook
--after scrolling laytur--
"Wow...she posted all of those stolen pics of US!" I said
"Well actually its quite hillarious at the same time" Bill said
"Yeah...it is-" I was cut of by the door slamming open the Bill hid y/n's phone on his pocket
"BILL! DIPPER! Y/N.MIRROR.PORTAL.GIT.HER!" She said between pants
"WHAT HAPPENED!" Me and Bill asked at the same time
Flash backs
"Hey Y/n! Wanna to that weird looking cave?" Mabel asked
"Yeah sure!" Y/n replied as they both went inside the cave
"Woah! Theres something glowing there! Come on lets check it out!" Y/n said as she pulled Mabel's hand
"Wow...A HUGE GLOWING MIRROR!" Mabel said
"I know!!" Y/n said moving forward to the mirror thing
"Hey y/n?" Mabel asked.
"Yeah-ahhhhh!!" Y/n said as she leaned on the mirror thing that turns out to be a portal and fell
--end of flash back--
"We need to save her!" Bill said
"Yeah!" I agreed
"Then lets go!!" Mabel said then we all went to the cave that Mabel is talking about and checked out the mirror stucktured portal
"Ahh! This.." Bill said
"What?! Where does it leads?" I asked him
"Reverse falls...where everything is reverse..personality,lives etc etc.." Bill explained
"Mkay...so...lets go and search for her" Mabel said as we all nodded and held hands and jumped to the portal
As we got out of the portal were still at the same place but the portal is glowing orange this time...
"Hmm seems like bothing happened" Mabel said checking the place out
"Lets check out the rest of this place" i said and Mabel and Bill nodded and headed back to the shack..that looks like nothing happened except for the name, is now called 'SHACK OF TELEPATHY'...we went in and we saw Gideon and PACIFICA?!
"AHHH! ITS THE GLEEFUL TWINS!!" Gideon said
"Gleeful? No no...our last names are Pines.." I tokd him
"Woah...we have the same last name...by the way this is Pacifica Southeast..my best friend!" Gideon said
"Wait Gleeful twins? Who are they?" I asked in confusion
