Takes place RIGHT after the events of northwest mansion mystery. And yes, since I saw that episode, I ship them haha. There's no end of the world because it got canceled sorry.

After Dipper got back to Pacifica they talked for a couple hours about Dippers adventures and her life. They would have kept talking but...

"Dipper! Its like 2 AM! Were all tired lets go!" Mabel screamed tiredly at Dipper.

"Just a minute!" Dipper turned back to Pacifica, "And then the zombie turned out to be a bunch of gnomes!"

"This is the weirdest story i have ever heard," Pacifica laughed, "I guess you got to go now... bye."

"Yeah, this was some crazy day," Said Dipper ever so awkwardly,"see ya!"

Dipper turned to leave as Mabel walked out the door when Pacifica hugged him again, but this time he (kinda) hugged back.

"Bye Dipper," said Pacifica, "see you around."

"yeah, bye." Dipper said and he walked out the door.

"Ha ha! Dippers got a girlfriend!" Mabel said as he came out.

"NO! I mean, no I don't... even like her! Why do you say that?" stuttered Dipper.

"You don't just talk to a girl for 4 hours ESPECIALLY not YOU!" Mabel stated.

"Were just friends," said Dipper trying and losing at defending himself.

"Yeah sure. They grow up so fast," Mabel said as she wiped away a fake tear.

"...so are we walking home or..." Dipper said as Soos pulled up.

"Hop in dudes!" said Soos as he stopped in front of the mansion.

"How did you know we were leaving?" Dipper asked as he got in.

"Stan was getting worried... OK no I was but dudes its 3 AM!"

"Yeah sorry Soos, Dipper was talking to his girlfriend." Said Mabel with a huge grin on her face.

"Kill me now!" screamed Dipper as the truck slowly made its way back to the mystery shack. Dipper slept good that night. In fact he slept so good that he slept in. His dreams with sprinkled with Pacifica, though he didn't know why. When he finally got up it was 9 AM.

"9 AM! I slept in too long!" Dipper said as he hurried to do his chores before Stan killed him.

Dipper ran down the stairs and through the kitchen.

"Hi Mabel, hi Pacifica," Dipper said as he hurried to the backyard. Wait... Pacifica? Dipper turned around and saw his sister and her ex-rival eating breakfast. This was going to be a long day.
