Dipper, Mabel and Grunkle Stan crawled out of the once blocked tunnel. They emerged in the same back alley, this time in the darkness of night. "Dipper, who was that?" Mabel asked.

"That was Bill... he wanted me to dance with him?" Dipper said it like a question, a bit weirded out. He noticed his navy blue bangs were still pulled aside and brought them back to cover his gem.

"Dance?" Stan started pacing. "What power could gems possibly use with dance?"

What was Chrysoberyl trying to accomplish? His mind flashed back to the scene, many of the monsters were multicolored and had no gems. It was like he fused a bunch of body limbs together. Was he going to do that to Dipper? Then why'd he want to dance? "Stan, you've got some 'splainin to do." Mabel said.

"I know kid, I know." He sighed. Everyone jumped slightly when they heard the groans from the tunnel. "I'll explain back at the shack."

--------------

Stan explained all he could, all he knew, in fact. How they were gemstones. Extraterrestrial beings. Aliens. He explained that Bill was defective and last time he escaped his bubble the previously mentioned (and missing) Hematite defeated him. He explained how Sodalite and multiple other gems live in Gravity Falls. Living completely undetected by gem technology.

He explained how their bodies were made of light and how that's all he really knew.

Dipper high fived Mabel. His pupils blew way up in excitement. "I knew we were aliens!"

Stan sighed. "Did you know that now you know you're going into a training camp?"

The twins' eyes widened. "Boo!" Mabel shouted.

"What? Why?" Dipper asked, voice cracking slightly.

"To learn how to use your gem super powers or something." Stan shrugged. "Classified. Don't worry though. I forgive you for abandoning me a few days ago."

Dipper rubbed his arm. "Oh yeah, sorry."

"Plus, you'll still live here. You'll just be going to the therapist every weekday morning to train." Stan shrugged. "You kids better get some sleep. Have a big day tomorrow. And hey, welcome back Dipper."

"D'aww thanks Stan." Dipper said, a bit shyly. He and Mabel climbed up the stairs into their rooms.

--------------

Sodalite gasped and a tear dripped from her left eye. "You'll actually let me help?" She trembled. "Train them?" She smiled as she ran in place. She took a deep breath and calmed down. "It's about time you rusty human."

Stan sighed. "Yeah, yeah. Just make sure they're back by noon." He left the place before he got in trouble for seeing something he wasn't supposed to.

Sodalite gave the twins an excited smile. "It's an honor. You should have seen you guys back in the day, you were such a duo. "A holographic image of two girls appeared behind her. They were dancing. A blue one with long pure white hair, the other, orange with beautiful golden hair. Both looked older then the twins. One danced with grace, the other in very rhythmic steps and swings.

Mabel started laughing. "Dipper was a girl?!" Dipper glared at his sister and pouted.

Sodalite shook her head. "Gems have no gender unless they choose so. They cannot have children in the same ways humans do." The holographic Mabel grabbed the holographic Dipper's hands and spun him around, when they came in for a hug they were covered in a blinding light.

"What happened?" Mabel asked, a bit concerned. Dipper's breath caught in his throat. What Bill wanted to happen.

The holographic twins, smiling merged into one, dark being. The being had white hair and grey skin. Her four eyes were multicolored and beautiful... in a creepy kind of way. Her arms were chimeraed, having striped skin all over. Mabel was entranced, but Dipper was hesitant.

"Can all gems do that?" He asked, playing with his hands nervously.

Sodalite sighed and muttered. "This is what you get Lune for living on a human world..." She took a breath and answered. "Of course, Lune. It's how gems show their love and attachment to eachother. Traditionally."

The twins looked to eachother in disgust with a "yuck" And "Gross".

"Although that was millennia ago, nowadays it's used for sport or battle." She sighed. "You guys will accomplish great things when you fuse again. It will be amazing."

The twins still wrinkled their noses. This was so weird...

Sodalite led them outside to the backyard. "This where we'll train. Lune with his sheild and sword and Solana with her crossbow." She smiled and mumbled something incoherent to the twins. "Hematite and her blade shooter..."

"All learning will be done back in my office." She smiled widely. "Who wants to learn how to dance?"

Mabel jumped for joy. "Me! Can you imagine me and Dipper flying around as that scary lady? We could totally pull pranks and no one would know it was us, right bro?" No answer. "...bro?"

Dipper shrunk where he stood. "I... i dunno, can't we learn about this whole sword and sheild business first?"

Sodalite nodded. "Right, you kids should probably learn about yourselves separately. Just in case if I... trigger... uhh..." she rubbed her gem nervously, looking for an excuse for Dipper, then snapped. "Some kind of separation issues for when you come apart." She coughed.

Dipper seen what she did and smiled. Mabel sighed. "Yeah, okay." She grinned to her brother. "Bet you I can figure out this weapon business first."

Dipper smirked. "I bet your emergency sprinkles I will."

Mabel gasped, then laughed. "I bet your summer diary on it."

Dipper huffed. "Mabel, it's a manly journal and you know it."

"You keep thinking that..."

Sodalite cleared her throat. "You won't need to figure it out. I'm going to show you." She paused. "As soon as Stanford leaves."

A far away. "Come on! I just got here!" Was heard from the nearby shrubs.

Sodalite smiled and summoned her gun, pulling it from her gem and shooting in his direction. A small ting was heard.

"My pen! Fine, I'm leaving!" The twins watched their Grunkle stumble out of the bushes back to the main street of the town.

Sodalite smiled. "When your weapon is ready to be summoned, your gem will glow. Most gems have different ways to activate their glow, some use-"

"Got it!" Mabel cheered, pulling a golden crossbow (loaded with a sunset orange arrow) from under her sweater.

Sodalite practically squealed. "Solana's already got it down!" She looked to Dipper, smiling with the same energy in a more calm manner. "Lune, do you want to try?"

Dipper scratched behind his head and looked to the grass, cheeks turning a tint of darker blue going purple. He smiled. "Sure, I mean, yeah. I want to try." His eyes read determination when he looked to his new teacher.

He took a deep breath and closed his eyes, practically meditating. The one thing on his mind was a sword and sheild. He heard some hushes from Mabel and opened an eye to see her smiling excitedly.

"...what?" His voice cracked.

"You did that projection thingy with your sword and sheildymagig. You know that thing I and the girls were talking about that one sleepover there was a dare and-" Dipper covered his sister's mouth.

"Sh! Yeah, I remember. Please don't talk about it!" The boy sighed and looked to his teacher in mild embarrassment. "So, how were the ways I could make my gem glow?"

"It's a mix of feeling, concentration and determination. I, use the joy of protection, concentrate on my weapon and am determined to not only teach you, but guide you in the right direction."

Dipper nodded and smiled. His gem glew lightly, and when he looked up, there was something behind his bangs. He grabbed it and pulled it out of his gem. A blue sword. Not too long after a sheild was presented before him and he grabbed it.
