Dipper sighed, "Alright, fine. Mabel, Great Uncle Ford, Grunkle Stan, Will, Bill, and... me, Mason, alright I usually go by Dipper."
"There's... something unnerving about the picture..." Cosmo spoke up.
"Like what, Cosmo?"
Cosmo frowned, "Why did you both make deals with a powerful demon?"
"Cosmo... Can you see why?" He asked.
Cosmo nodded, "A little... I can see the scenes play out a bit... at least, from the deal made, and... what happened afterwards..."
"... Mabel? Do you want Dipper to know?" He asked, looking over at her.
She looked down, before nodding, "It's been long enough from it... that, I think it's okay to tell him..."
"What? Mabel, what did you do?" Dipper asked, confused.
He sighed, "You'll see. Cosmo, can you tell us what Dipper's was?"
"Well... the first one was Dipper's... He was going to get answers, but... he'd become a living puppet..." Cosmo frowned, "Dipper and Ford had darker auras because of the possession... They were marked."
He bit his lip, looking down, "... and Mabel?"
"... She was tricked into a deal. She didn't want summer to end, and... she'd get that, but... she'd have to give something in a snow globe like object away..." Cosmo looked down, "It didn't end well for anyone, except for the demon..."
"Oh no... Mabel, you didn't..." Dipper frowned.
Mabel frowned, "It wasn't my fault..."
"I know... I remember what Ford said. Besides, you didn't know much about the rift..." Dipper sighed.
Mabel nodded, "I know... I'm sorry..."
"It wasn't your fault." He sighed, "It's mine, and we all know it."
The triplets frowned, "What are you talking about?"
"Nothing... We can explain later. Right now, you should have a talk with Ford..." Dipper mumbled, "He's the genius out of all of us."
Luna smiled, "A genius?!"
"Yeah, a genius... that loves the supernatural..." He smiled, "You'll like him, I'm sure."
River looked down, "I can hear something..."
"What is it?" He asked, confused.
River frowned, "It says that it's mad... at you... and... other people..."
"Who?" He asked.
River bit her lip, "It's mad at you, some people named Mason and Star Gleeful."
"Shooting Star, Pine Tree, Tides, Galaxy, and Eclipse, go down into the lab. Pine Tree and Shooting Star know where that is. Stay there until I contact you, River. Alright?" He ordered.
The triplets nodded, "Yes, father."
Dipper and Mabel ran over to the venting machine, punching in the secret code, before going down the elevator with the triplets. Everyone was silent. Cosmo frowned, not happy that he couldn't really see... other than Dipper, Mabel, and his siblings auras.
An older looking man was surprised to see them, as he asked, "They found us? Why are they down here? Where's Bill?"
"They did, they figured it out... at least, partly. Something's happened. Something, or something... who's mad at him, contacted River, and... she admitted to all of us what she was hearing. He told us to take them down here. I'm assuming that he's going to deal with it... Whatever it is," Dipper explained.
Cosmo frowned, looking at the man, "Are you Ford?"
"Yes, I am... how'd you know that?" Ford asked, kneeling down in front of Cosmo, brushing his short blond hair to the side.
Cosmo bit his lip, "I can see auras... and, your's is darker than anyone else's... a case of long time possession... and... you've been marked by them, as well..."
"What do you mean, 'marked'? I know the rest of it, but... the marked part is new to me," Ford admitted.
Cosmo looked down, "Marked as someone who won't die, an ally, and... an apprentice..."
"Apprentice? To who?" Dipper asked, confused.
Cosmo shook his head, "I don't know. I've only learned about this ability recently, so... I can't tell who he's apprenticed to... Sorry."
"I have an idea as to who..." Ford spoke up, "Can you three know what's going on upstairs?"
River frowned, "Something bad... someone's hurt..."
"Someone's getting chained to a table..." Cosmo and Luna spoke up, at the same time.
River frowned, "They're not happy. They're begging for mercy, and... are trying to contact me, but... father isn't letting them."
"What do they look like?" Mabel asked, biting her lip.
Cosmo bit his lip, "A boy... with black hair..."
"Black hair...?" Dipper was confused.
River's eyes widened, "We can go back now... although... father's saying that Mabel won't like it..."
"Why wouldn't I like it? It's someone who hates Bill... and... also..." Mabel stopped, before looking over at Dipper and Ford, "... no... It couldn't be him... He... he never hated anyone..." She dismissed the thought, running over to the elevator, everyone else waiting for her. Everything was silent for a moment.
"What's wrong, Mabel?" Cosmo asked, "You're sad..."
She looked down, "Nothing... just... thinking of someone..."
"Who?" Luna asked, curiously.
She frowned, "An old friend... who's been through a lot. If it is him... then... I don't know what I would do. He really suffered a lot... so, I was surprised that he wasn't mad and angry at the people who made him suffer. He was really upset about it... fearful, even. He was fearful of us, when we first met him for the first time... like a broken, scared, mentality, as Gold had described him to me, when I had asked what was wrong with him. He was a lot different from Gold... which was odd to me, until... well... until he... almost burned my hair... Then I learned that... he was just hiding his anger, but... as emotionally unstable as he was, it... didn't help him at all... We tried to work through it, but... if it IS him, then... it was for nothing... and... he snapped... just like his older brother..."
"Mabel, it's not going to be him. It won't be Blue, I promise. It'll be someone else... You know, like... maybe, Gideon Pines or Pacifica Southeast... maybe they found out about what Gold had done in the past..." Dipper reasoned, trying to calm his twin sister down.
Once they did get to the shack, Mabel gasped, looking at the boy chained to the table. She sniffed, noticing his light blue tipped black hair.
He scowled, kicking the boy, "Blue, wake up. You've got some people who want to talk to you."
"M... Mabel! Mabel, please! Help me! I'll do anything! Please, just... don't let him kill me!"
