Mabel runs downstairs and sees Dipper at the dining room table eating cereal and flipping pages through journal 3

Mabel: morning bro-bro

Dipper: Mabel we need to get back home. 

Mabel: but I like it here.

Antlia and Leo go downstairs to the dinning room. Leo takes out a some kind of juice? 

Leo: look sis, I made 'Leo' juice. 

Antlia: um, that juice has plastic dinosaurs. Did you take aunt Mabel's recipe. 

Leo: no, she gave it to me. 

Antlia: whatever. 

Antlia and Leo enter the gift shop of the mystery shack followed by Dipper and Mabel. Chase was at the cashier like how they usually had Wendy at the cashier. Hera was fixing things, like how Soos used to fix things. Stan was making sure people payed twice the money, as usual. Wendy left to work and Soos had went on a date with Melody. One thing caught Mabel's eye. She noticed Antlia looking the same way at Chase as Dipper looked at Wendy. Leo noticed this too. Antlia was writing something on a piece of paper on a clipboard, The closer Mabel looked, the more clear the writing became. It said "I am pretending to write something down" 

Mabel was so close to squealing, but Dipper had noticed what Mabel noticed and covered her mouth. Leo was next to the counter where Chase was at, all the sudden a really fun song starts playing.

Leo: RANDOM DANCE PARTY FOR NO REASON. 

Leo and Chase both start dancing. 

Chase: hey Antlia, *Antlia looks up quickly* 

Antlia: huh? 

Chase: aren't you gonna join in on this? 

They stop dancing and Antlia walks over. 

Antlia: um, I don't really dance. 

Leo: yeah ya do! Dad and Grandma made use to make her dress up in a costume and do the "lamby dance"

Antlia: Leo, now is not the time to talk about the Lamby dance

Chase: lamb costume. Were there like little ears and a tail? 

Antlia: well um...

Leo: Antlia would prance around and sing a song about praising. 

The close makes a notice point at 5:00pm

Chase: oh, the gang is waiting for me

Antlia: hey maybe I... Or we could hang out with you guys?

Chase: I'm not sure. My friends are pretty intense. How old did you say you guys were? 

Antlia: oh were um... 13 so... Techanacly a teen

Chase: alright. You're in. Let me get my stuff.

Chase exists. 

Leo: um Antlia, since when are we 13? Is this a Leap year

Antlia: oh, come on Leo! This is our chance to hang out with the cool kids... And Chase whatever. 

Leo: I KNEW IT! You love him! Love love love love love! 

Antlia: oh shut up! 

'Whispering

Dipper: What do you think Chase's friend are like. Do you think maybe there a lot like Wendy's

Mabel: Oh my god. What if there's and other Robbie. Eew. 

Dipper: it'd probably be a girl. 

Mabel and Dipper follow Antlia and Leo outside but they stay out of sight. They spot a teen girl who looks like Robbie but also a it like Tambry. 

Dipper: Mabel, look. 

Mabel: oh my god. They actually got together. 

Then they noticed other three girls and one boy. One girl looked like Thomson, but she was skinning with shoulder-length brown hair and green eyes.  Another girl who was African American had black shoulder-length hair and dark eyes. Then another girl who was irish, and had Short blonde hair. Then there was another boy who was a but dark skinned but also light. He never got off his phone sorta like Tambry.  The boy also looked like Robbie and Tambry. Next to the teens were a van.

Mabel: they had two kids. 

Dipper: it's weird I never saw Robbie and Tambry together, but they turned out to be right for each other. 

Mabel: me neitheir. But Apparently Waddles did. Wait a second, were is Waddles?! 

Dipper: oh he's still here. Leo is playing with Waddles in the living room. 

Mabel: oh. Phew. 

The van leaves 

Mabel: so I guess, Antlia is the new you and Leo is the new me. 

Dipper: yup. 

Mabel: cool. Let's get back inside. 

They walk back inside the mystery shack. There is a note left on the counter.

'Left with Dipper to the hospital, Pacifica is having another child. By the way, does anyone having any money they could give me. I'll give Stan bucks back. -Stan'

Mabel: OMG! Dipper your going to be a father of three kids! 

Dipper: I--- don't care. 

*kncok knock* 

Dipper and Mabel both get the door. On the other side is a 12-year old girl with white hair put into a simple braid. 

Mabel: hi. 

Ivanna: hi, I'm Ivanna? One question: is Leo home and follow- up question: who are you two? 

Mabel: were... Um....

Dipper: *sigh* were from the past. I'm Dipper, and this is Mabel.

Ivanna: oh. 

Mabel: wait. You believe us? 

Ivanna: of course I do. Leo told me all about that crazy journal 3 book. 

Mabel: who's your father? 

Ivanna: oh, my father is Gideon Gleeful.

Then Mabel finally noticed that Ivanna was wearing all blue. A blue shirt and blue skirt. She ven had that weird gem thing. But it was on a clip in her hair. 

Mabel: oh...

Dipper quickly pulled Mabel aside. 

'Whispering' 

Dipper: We can't trust her! 

Mabel: maybe she's different.
