"I know. I... do have a question for you, though..." Will looked up at him.

Dipper looked at him, "What is it?"

"... What would you do if you were immortal?" Will asked.

Dipper sighed, leaning against his bed, "I don't know. Try to learn everything, I guess. I love learning and mysteries and the such. Hey, maybe I could end world hunger... but... that's wishful thinking. Why are you asking?"

"... that has to do with the solution to the future problems we'll probably have. The solution would be to make you both immortal."

Dipper was surprised, "Are you serious? This isn't a joke, right? Because, this would be a horrible joke."

"This isn't something that anyone would joke about, Dipper." Will sighed, "I'm sure you know that."

Dipper frowned, "What about the rest of our family?"

"... That depends," Will looked down.

Dipper sighed, "Depends on what?"

"... never mind. It... doesn't matter. I'll go. See you tomorrow, Dipper."

Everyone was quiet during breakfast, the next day. Nobody said a word.

"If there's something you want to say, say it," He spoke up, looking at Sammy and Janie.

Sammy sighed, "Mabel, Dipper, we've decided that you're going back home with us. You shouldn't be around these... deceiving... humans..."

"Don't you dare call me a human!" He scowled.

Sammy snickered, "You're just going to deny what you are?"

"I'm not denying what I am. I'm just saying, you're wrong about what I am," He growled.

Janie looked over at Dipper, "See? You clearly don't need to be with this idiot. He believes that he isn't human, when clearly... he is."

"Billy..." Will mumbled.

He growled, "Yeah, because I don't want you both to freak out when you realize your son is going to marry a triangle."

"What?" Sammy asked, confused.

Will frowned, "Billy... stop it..."

"What are you talking about?" Janie asked, confused.

He sighed, "Blue... make them go to sleep."

"But-" "-NOW, Blue."

Will whimpered, before snapping his fingers, frowning when both of the twins' parents fell over.

"Let's go, Will," He sighed.

Will frowned, "Okay..."

Janie and Sammy both looked around, confused at their grey surroundings.

"I'm sorry..."

They turned around, noticing a small blue triangle that was crying.

Janie frowned, "What are you? Why are you crying?"

"... I'm sorry... I'm so sorry..." Will cried.

Sammy scowled, "Speak."

"You don't get to command him."

They both backed away, seeing the yellow triangle that was glaring down at them angrily.

Will sniffed, "Billy..."

"I know. I'm sorry, Will..." He sighed.

Will looked at them, "... I'm sorry..."

"Why are you sorry?" Sammy asked.

Janie frowned, "What are you?"

"I... a... I'm... a demon..." Will mumbled, before he began to cry again.

He sighed, "Will... you can go if you want."

"No... I want to stay..." Will admitted.

He sighed, "Alright."

"So... you're demons... you're not going to hurt us, are you?" Janie asked.

He snickered, "Do you think Will would hurt anyone?"

"No, probably not," Sammy admitted, looking over at the small crying triangle.

Will looked down, "I... I've killed before, though... I was forced to kill two of my friends... and... it was horrible..."

"I know, but the ones who made you do it, are now dead as well... and you killed them," He snickered.

Sammy stared at him, "What about you?"

"... Well... unlike Will... I've never actually killed. I've hurt people, but never killed anyone," He laughed.

Will sighed, "What about home?"

"... right... I guess that was a lie, then..." He admitted.

Janie frowned, "What happened to your home?"

"... I... destroyed it... on accident. I was really mad one moment, and the next... everything was crumbling around me... so I grabbed Will and left... he's the only family I have left, now. The only thing from home..." He sighed, "We're the only survivors..."

Janie gasped, "Oh god... do you feel bad about it?"

"No, actually... home is... a lot different than Earth. It was a world of flat emotions, flat beings... everything was flat... and it was horrible," He admitted.

Sammy bit his lip, "How old were you both when you destroyed it?"

"I was a child, and Will was just a toddler," He sighed.

Janie frowned, "Did you look like humans then?"

"... no, we were still shapes. We DID make human forms though... since this place probably wouldn't like shapes..." He admitted.

Sammy sighed, "... and that's what we were seeing in the waking world."

"Yes," He admitted.

Janie looked around, "So... what is this place?"

"This is the Mindscape. This was my second home after our dimension collapsed." He admitted, "Because humans can only visit in their dreams... you can do anything you want here."

Sammy sighed, "What's your first home?"

"... The Nightmare Realm... but we can talk about that place later..." He sighed.

Janie frowned, "What about our kids? ... and Ford? Do they know this stuff?"

"Oh, yes... they definitely know about this stuff," He laughed.

Sammy sighed, "So... why Gravity Falls? Why stay here?"

"You don't know? This is weird central. Besides, there's a barrier that keeps anything weird from going outside of this town, so even if I wanted to, I can't leave this town." He giggled, "There's a lot of supernatural and mythical stuff here... there's even stuff in the house that is mythical and supernatural... and no, I'm not talking about Fordsie's polydactyl."

Janie sighed, "What's supernatural and mythical in the house?"

"Well... that's Blaze and Petunia. Blaze is a foxxen, which is pretty much a kitten and fox hybrid, and Petunia is a unicorn," He snickered.

Sammy sighed, "Fine. Can we at least wake up now?"

"... fine."

Everyone else was surprised, when both of the twins' parents woke up.

Dipper frowned, "Dad..."

"It doesn't matter, Dipper. You're not leaving this place," Sammy sighed.

Mabel beamed, "Why?"

"... that doesn't exactly matter, Mabel," Janie spoke up, looking at the two boys.

Will smiled, "I'll go get Blaze. You want to get Petunia?"

"... no, I'm good," Mabel sighed.

Will nodded, running up the stairs, before bringing a small fox kitten hybrid with orange and red fur down the stairs.

Janie was surprised, "That... is actually adorable."

"Yeah, don't let its cuteness fool you," He grumbled, "most of them are actually deadly, but... this one isn't."

Janie frowned, before looking at Will, "Can I pet him?"

"Yeah, it's safe, don't worry." Will smiled, "We wouldn't have brought it into the house if it was dangerous."

He coughed, "Yeah..."

Janie nodded, starting to pet Blaze, who quickly began to purr, "Wow... he's really cute and cuddly..."

"Well... he IS part fox, and foxes are apart of the dog family, so..." He smiled.

Sammy nodded, "Good point. You know a lot of things, don't you?"

"Of course I do. I know lots of things," He grinned.

Dipper, Mabel, and Ford all shivered.

Will sighed, "What do you want to know?"

"... well... was Ford telling the truth? ... about what happened, anyway?" Sammy asked.

He sighed, "Yes, he was."

"He's... kind of a jerk sometimes," Dipper laughed.

He blushed, "Pine Tree... shut up..."

"I'm not shutting up," Dipper grinned.

Sammy sighed, "You two just need to get a room."

"They already have their own room," Ford sighed.

He grinned, "Hey Sixer, have you removed the stuff from the second floor of your lab yet?"

"..." Ford blushed, looking down, "No..."

He laughed, "Then why don't you just show them what's down there?"

"No! The only ones who's seen that stuff, is Dipper, and I hope to keep it that way," Ford sighed.

Dipper laughed, "That makes sense."
