The House
"I don't recognize the name, but we'll keep a look out for it. Maybe we could ask the Mayor or someone at the Postoffice, I'm sure they'd know."
Looking over the bathroom the weirdest things Lyra notices are a shag toilet seat cover in a jagged white and black stripe pattern and a number of new cans of compressed "Hair product" that she's pretty sure the chemicals listed are both highly flammable and atmospherically corrosive.
Alexandira helps reveal the cause of the dust marks to Cicivexa.
Velma shrugs at Kino's question.
"Sure I guess, if you think they'll be useful. They aren't exactly rare or anything."
Once everyone makes it back to the Great Room Fred makes a sort of announcement.
"Alright gang we're going to head into town to pickup some breakfast and investigate the situation with the house and letter more. You guys are welcome to ride in the back with Shaggy and Scoob if you want, I'm sure there will be enough room."
Shaggy stands up at the mention of food and gestures to Scooby sitting on the couch.
"Go get the stuff Scoob."
"The rack ripe Raggy?"
Shaggy gets a look of disbelief and stares at Scooby for a second.
"We've got guests man, what do you think?"
"Reed it is den."
"Hey and don't forget the hooka this time!
Shaggy shouts a Scooby as he trots to the back room and comes back with a backpack.
The Mystery Machine
Sure enough with a bit of corralling after Fred, Velma, and Daphne climb into the front seat the first few people follow Shaggy and Scooby into the back of the van filling it up. But with a bit of urging from Shaggy to "Scooch down a bit." and "Sit a little closer together" everyone, miraculously, fits in the van.
As Fred pulls out of the driveway he comes to a stop by the mailbox and postwoman filling it. He rolls down the window and their conversation is hard to hear, but he shows her the letter and they exchange pleasantries before he rolls the window back up and turns to the back of the van.
"She said she didn't recognize the initials or handwriting, but she did deliver the letter a while back."
The trip towards town starts pretty smoothly, the roads are old with only the occasional hill or farm to twist around. After a while the front seat gets kinda quiet and the road noise and bumps fade away. Shaggy opens up the backpack and pulls out a baggie of somewhat crushed green plant material and something glittering blue. He loads the hooka with a generous portion and lights it. He takes a couple deep puffs off of it and exhales thick purple smoke towards the top of the cabin with a single long "Groovy"
He passes the hooka to Scooby who takes a puff and exhales more purple smoke through his nose, then pulls out a what looks like a baby wipe to clean the rim.
"I bet you've got a lot of questions like 'Why are we here?' or 'Who am I?' well feel free to ask, we've got all the time in the universe."
He leans back against the wall of the van, any hint of sound or vibration from the engine and outside world gone by this point.
"And like feel free to take a hit man, just remember to puff puff pass."
