Chapter one

"Attention passengers will be arriving in Gotham airport in 10 minutes please place your trays in the upright decision and be ready to exit the plane" said the flight attendant.

Dipper closed his book and placed it in his book after worlds he started shaking his sisters shoulder to start waking up his twin sister who was asleep on his shoulder.

"Mable wake up where going to be landing soon" said Dipper trying to wake up his sister.

"Mm leave me be" said Mable still sleep.

"Mable wake up we have to get going." said Dipper trying to wakeup his sister again.

"Mm glitter kitties" said Mable in her sleep.

"Mable theirs a handsome man looking at you." said Dipper

"I'm up, how do I look, where's my makeup bag." said Mable looking left and right for said bag. only to see her brother laughing at her.

"Very funny Dip why did you wake me up" asked Mable

"The flight attendant said will be lading soon." said Dipper

"Oh well thanks so do you know if Great uncle Stan is meeting us at the airport or not?" asked Mable

"He said hill be sending his buttler to pick us up." said Dipper

/time skip/

As the twins where entering the air port they looked around and saw a heavy set man holding a sign that said Dipper and Mable Pines. Walking over to the man they introduced themselves.

"hey dudes Mable and Dipper pines right" asked the man

"Yes are you Soos" asked Mable

"Yep that's me I'm here to take you two to the mansion." said Soos folding up the sign and placing it in a near by trashcan.

/In the limbo/

"So Soos what can you tell us about Great uncle Stan" asked Mable going threw the limbos mini bar pulling out two candy bars.

"Well master Pines is a rather private man to the press but is a very good man, he was very excited when he was told you where coming" said Soos

"Huh is that it" asked Dipper going over his paperwork for Arkham he kept going over a lot of he cases and several of them seemed to be meta humans or super smart people.

"What you got their dude?" Asked Soos

"Oh these are patient manifests for some of the patience I'll be working with at Arkham" said Dipper mindlessly going threw each sheet studying each person.

It took all of Soos will power not to slam on the breaks when he heard what Dipper said "Duds your joking right" asked Soos worried about the answer

"My brother is not he could have interned in any asylum but he just had to choose the one with the worst guys and gals to ever live." Said Mable munching on her candy bar.

"Hey a I want is to help them not lock them in jail like you do these people need help." said Dipper angry with his twin for being so harsh towards the people of Arkham.

"No what they need is to be medicated and locked up where they can't hurt innocent people." Said Mable glaring at her twin.

"Dudes come down you can talk about this later right know where about to enter the grounds of the mansion" said Soos

Distracted from their argument for a minute the twins looked out the window to see a giant brick mason with dark green vines climbing up the side and beautiful Gothic design.

When the twins got out of the limbo they got their bags out of the car and started walking up the stairs to the front door. Where a women with red hair and a fitted suit was waiting for them.

"Hey guys you must be Dipper and Mable I'm Wendy I work for your uncle like his big lug" said Wendy jabbing Soos in the gut.

"It's nice to meet you" said Dipper looking around the mansion and it's impressive architecture, while Mable was talking to Wendy.

They where all drawn from what they where doing by the sound of someone coming down the stairs the group of four turned around to see a man around his early 40 standing their in a black suit.

"Dipper , Mable it's so nice to finally meet you" said the man
