Family Reunion

They returned to the attic bedroom and landed on the bed, which collapsed under their combined weight.

"Like, let's get out of here," said Shaggy.

Mabel fired her grappling hook down to a tree, and they used the line to zip down to the ground.

Soos, Wendy, and the other members of Mystery Incorporated were there waiting.

"You've got the sword?" Fred asked.

Dipper nodded, pointing to the weapon he had put through his belt.

"Who is this other person?" asked Velma.

"That's really complicated," said Mabel.

"I'm Fiddleford McGucket."

"In the body of the author of the journals, our other great-uncle," said Dipper. "There was a swap."

"Just as I suspected," said Velma.

"All right, we're set for the mission," said Fred. "Mystery Incorporated plus Gravity Incorporated needs to stop the Evil Entity."

"I'm ready," said Wendy with a grim smile, touching the axe at her belt.

"I'm ready too, dudes," said Soos. "I guess."

"We've got everyone else, but we couldn't find Waddles," said Daphne.

"No! Where could he have run off to?" asked Mabel. "Waddles!"

"If required, I believe we can use an animal mascot from a former team instead, such as Scooby-Doo or myself," said Pericles.

"You've become quite an expert on this all of a sudden, Pericles," said Fred,

"Many things are coming back to me from my former existence," said Pericles, with a cold glint in his eyes that went unnoticed.

"Soos, before we go, there's one thing I have to tell you," said Mabel.

"What's that, Mabel?" asked Soos.

"It's a big shock," said Dipper. "You might want to sit down."

Soos sat on the ground. "Okay dudes, I'm ready for anything."

"I'm your Mom," said Mabel.

"Umm, really? I don't get that... Wouldn't my Mom be older than me? Or am I all mixed up?"

"There's time travel involved," said Dipper. "It's quite a story."

"We'll tell you all about it after the mission," said Mabel.

"Like, if we survive it," said Shaggy.

"I just had to tell you the basics," said Mabel. "Just in case."

"That explains why I've always felt so close to you," said Soos. "May I have a hug, Mom?"

"Of course," said Mabel, hugging him.

"I'm your uncle," said Dipper. "Our real names are Domiclese and Callisto. And your name is Arkas."

"Too much info to handle at once, guys," said Wendy. "Can we stick to Dipper, Mabel, and Soos?"

"Sure, Wendy," said Dipper. "I'd like you to know something, too. I've been older than I look now. A bit older than you."

"I'll... keep that in mind," said Wendy.

They found the vending machine secret door open, with steps leading down.

"I had no idea this was here," said Dipper.

"Has Grunkle Stan been keeping secrets from us all along?" asked Mabel.

"Yep," said McGucket. "I'm sure he has."

"Agreed," said Periclese, who was perched on McGucket's shoulder.

They found an elevator with a combination code, and it was unlocked. Everyone got in.

"This is a bit too easy," said Fred, pushing the down button.

"Like, prepare for a trap," said Shaggy.

"Reah, a rap," said Scooby.

Pericles closed his eyes for a moment, and when he re-opened them they were yellow with vertical pupils.
