Greg: Guys!!! There's this new attraction in Oregon.

Garnet:... What do you need...

Pearl: What is Oregon?

Steven: The west side... What's the attraction?

Greg: There's this place called the Mystery Museum... I mean the Mystery Shack

Garnet: What do you want to go somewhere you can't even memorize the name of?

Greg: ... Well gee, Garnet... The name is all weird... So are you guys comin' or what?

Peridot and Lapis walks in the living room.

Peridot: What? Were you guys going somewhere and leaving me with THOSE two!?!?!?!?!

Peridot points up to Bismuth and Lapis

Garnet: Are we going on Loin?

Greg: I don't think we have a choice

Greg looks at the car outside knowing that the car won't even make it to the gas station. Then everyone stacks on top of lion with no warning

Steven: Lion, Take us to Oregon... Where in Oregon are we going????

Greg and Garnet: Gravity falls

Lion attempts to get up, through the quivering of his legs, he manages to take 1 person and 6 gems through a portal.

Connie: I came as soo--... where is everybody???

As soon as Lion and everybody was transported to Gravity falls, Lion collapsed.

Everybody walks into the mystery shack garnet, moves away from the group and into a different area of the shack, she looks at all the souvenirs. But then she sees a Garnet titled, The Mystery stone. Garnet is mortified and infuses immediately Ruby looks horrified, and sapphire is crying

Ruby: Th-- This can't be a real garnet!?!?

Sapphire: It.. I think it is 

Ruby runs off, and sapphire walks back to the lobby just behind Ruby.

Pearl: What happened?????

Sapphire: (voice breaking) Ruby LEFT!!!!! (cries)

waddles sees the door open and makes a run for it. just as that happened, Wendy and her friends pulled up in a van pearl and amethyst try to run after Ruby, when Wendy stopped them

Wendy: Whoa! I love you outfits where did you get them 

Amethyst: It's a secret (frankly) these have been around for hundreds of years.

Pearl: what are you doing? We need to get ruby.

Amethyst: Ruby can wait! she just needs some alone time! Garnet can't stay together forever!

Pearl: ...Well, Everyone deserves a break...

Amethyst: (looking at Wendy) Where are you guys going?

Wendy: We were just getting snacks. Were going to this abandoned mining cave

Pearl: (hesitantly yet trying to look cool) Lets Go Then!

Pearl walks with her legs flaring out into the crowded van as Amethyst follows

Wendy: Hey guys, these two are coming with us, Amy and Pearl right?

Pearl and Amethyst: Uh... yeah?

Sapphire sat down in the middle of the upstairs bedroom where Dipper and Mabel fought the wax figures.
