[In Mabel's room]

Mabel:*Searching up the band* Oh come on, if the band exist then it must be in another dimension. Grace!

Grace:*Teleports to Mabel* What wrong?

Mabel: I need help finding the band.

Grace: Uh, ask Swift she knows the band and she's a fan of them.

Mabel: Could you contact her?

Grace: Sure if she's not busy.

[Time Skip]

*A silver portal opens up*

*Jumps out* Nice seeing you again.

Mabel: Swift! *Tackle hugs her*

Whoa nice tackle.

Mabel:*Lets go* Sorry, I need help with the band Grace mentioned about. Bangtan or something?

BTS.

Mabel: BTS?

The band you want to know about. Bangtan Sonyeondan or Beyond The Scene.

Mabel: Oh yeah I wanna know but in this home dimension of mine doesn't exist here.

Not to worry, here. *Pulls out all albums of BTS*

Mabel: Oh wow that's a lot! Their faces are so handsome and soft.

Maybe you'll like to listen to one of their songs. You might like them. *Plays the song*

Dipper:*Covers his ears* Mabel can you lower down! I'm trying to read!

Mabel: What?!!

Stan:*Wearing earmuffs* Sweetie lower your music down!

Mabel: WHAT?!!!!

Ford:*Wearing earmuffs for airplane takeoffs* Mabel lower your music down!

Mabel:*Pauses it* Sorry guys.

Stan:*Sighs* It's okay next time not too loud Sweetheart.

Mabel: Okie Dokie!

Dipper: Mabel when did you start liking this BTS thing?

Mabel: Swift introduced me to their music. She told me about them and their fandom name A.R.M.Y. It sounds so cool.

Dipper: I wouldn't get my hopes up on that band.

Mabel: I actually do she told me facts about them like where they live, what's their favorite colors and what's their favorite activities.

Dipper: Okay but I think other people in Gravity Falls won't understand them plus how would everybody else react to them.

Mabel: Oh don't worry Bro Bro I already introduced Candy and Grenda to them.

Dipper: And?

Mabel: They were stunned with amazement. Surprisingly they are way better than Sev'ral Timez.

Everybody:*Gasps from Mabel's opinion*

Mabel: Something wrong?

Dipper: N-No nothing just never knew you would say those exact words.

Mabel: Time flies Dipping Sauce and excuse me I'm going to Candy's house. *Skips out of the shack*

Stan, Ford and Dipper: .........Grace!
