Many gems live on this foreign world they call Crystal Falls getting away from homeworld's authority. Bill is a Jade (maybe?) and Dipper is a moonstone (maybe?)

Crystal falls unknown territory

"Hey Jade wanna go and practice our weapons in the rock valley?" Dipper asked summoning their staff.

"Naw dude I rather watch the stars tonight." Bill answered lying on their back twirling their weapon a cane.

"Beautiful night isn't it?" Dipper asked sitting next to Bill "Which star do you think is near homeworld?" They asked.

"I don't know." Bill said taking a look around "Where is your sister gem?" They asked.

"Sunstone is out with our sister gems having a shape shifting contest." Dipper answered then shape shifted into a bear "Things like this or this." Turned into a cat "Or cute creatures like this!" They turned back to normal.

"Gems like us are too much fun for homeworld gems to understand." Bill said standing up then grabbed Dipper and leaped high into the air and twirling in the air making them blush as they slowly came back down.

"You know normally moonstones aren't aloud near someone as important as a high standing Jade like you." Dipper said looking down.

"That's because it's stupid." Bill said bluntly surprising Dipper "Every gem should have a right to choose what they want to do regardless of gem structure!" They said boldly.

"That's so beautiful." Dipper said tearing up so Bill wiped their are away.

"Not as beautiful as you are." Bill said smiling lovingly at the other gem.

"Wanna dance?" Dipper said surprising Bill who then smiled and nodded taking their hand and slowly starting dancing with them.

"I'm glad I get to do this with you Moonstone." Bill said leading them and then dipped them.

"Me too jade me too." Dipper said as their bodies began to fuse into one being made out of their love for each other.
