"I think this is it," Fred Jones said, stopping the Mystery Machine in front of a yellow house in the suburbs. "Is this the right place, Shag?"
"I don't know," Shaggy Rogers answered.
"What do you mean you don't know?" asked Daphne Blake, turning around to look at Shaggy. "Have you never been here?"
"Like, no."
"You mean in all the time you two dated, you never went to her house?" asked Velma Dinkley.
"We weren't even together that long!" Shaggy said defensively.
"It doesn't matter," said Fred. "I'm pretty sure this is the right address. Come on, gang."
"Scoob, you should probably, like, wait here," Shaggy told his loyal companion as the four humans stepped out of the van.
"Row come?" Scooby-Doo asked.
"She's allergic to dogs, man, remember? We can't take you in her house. Sorry, buddy."
"Besides, we shouldn't be long," said Daphne. "I, for one, want to get this over with very quickly."
Scooby frowned, but he complied. He climbed into the front seat and watched as his friends made their way to the front door.
Before any of them could knock on the door, it opened, and a familiar face greeted them.
"Thank God you all are here," said Mary Jane. She was a friend that the gang had made on Spooky Island, an amusement park where they had solved one of their most dangerous mysteries ever. One at a time, her eyes met theirs, lingering on Shaggy's the longest.
Shaggy started to say something, but Fred spoke first. "Where is it?"
"Follow me," Mary Jane said, opening the door all the way and leading them into her home. "I know the place is a mess. I'm sorry. I've been a little paranoid ever since the Spooky Island thing."
The gang made their way around, between, and over several piles of books, clothes, canned foods, even small safes, until finally, they were all standing in what appeared to be a study.
"I found it in one of the pockets of this suitcase. It's one of the bags I took to the Island," Mary Jane said. "I didn't put it there, I swear. I didn't put anything in that pocket."
"Which is why you didn't think to look in it until this morning, right?" asked Velma.
"Exactly. I knocked over the suitcase on my way through here, and I heard it in there when the suitcase fell."
"I'm probably gonna regret this, but…" Fred hesitated, "show us."
With a worried look on her face, Mary Jane opened the pocket wide enough for everyone to see what was inside.
"Shit," Daphne said, covering her mouth after realizing she had said it out loud.
"That's really it," Velma said, her eyes as wide as everyone else's. "The Daemon Ritus."
