Dipper Pines reads Journal 3, Mabel is outside playing with Waddles, everything is right with the world...then suddenly, Mabel starts running into the (Mystery) Shack, "Dip, Gideon and Pacifica are here!" Mabel says, "What?!" Dipper said. "Deal?" say Gideon, "Deal." Pacifica.
Gideon is walking out of his house, mad, so is Pacifica, Gideon and Pacifica both say in sync "I'll get that (Dipper for Gideon and Mabel for Pacifica) Pines!". Gideon looks at Pacifica in surprise, "You hate the Pine twins?" says Gideon, Pacifica answers "You do?", both say at the same time "YES!". "Lets get our revenge...deal?", "Deal.".
Dipper and Mabel goes outside to investigate, "What are you doing here?" says Dipper. "We're here to eradicate you!" say Gideon. Then, the four of them starts fighting eachother. "We need back-up" says Gideon, he pulls out Journal 2, and tries to summon Bill (Cipher), but accidentally says the wrong words, but said instead "Tryamjulum, emtamjulum. metevoriz donimus vemtiun. Netevoris femetisariun!", then...they awoke, they tried to resume their fight, but they...passed through each other. "OH NO! ARE WE GHOSTS?!" said Dipper. But Mabel said "Isn't the Mystery Shack supposed to be there?" pointing to the Tent of Telepathy. The four of them poke their heads inside the tent to see 2 kids looking like Dipper and Mabel, but wearing the clothes of Gideon, and they also looked into the crowd to see 2 kids looking like Gideon and Pacifica but, Gideon had the clothes of Dipper, and Pacifica, Mabel. "We are the Telepathy Twins!" said the 2 kids on stage, but then they started singing 'Lil 'Ol Me, but instead of Mabel it was Pacifica, and they 2 kids on stage sounded like Dipper and Mabel, then the kid in the crowd who looked like Gideon said "They're frauds". Then Dipper, Mabel, Gideon, and Pacifica looked at each other when the 2 kids on stage said "Dipper and Mabel Gleeful, The Telepathy Twins!".
