Iiiiiiiitttt'sssss HIATUS TIME!
Okay yeah, it sucks. But while we're desperately waiting for the next episode of our Gem-filled wonderland, I thought I'd come up with an origin story for my favorite Crystal Gem, Garnet.
Just keep in mind this is all my headcanon. Nothing is confirmed and there is nothing hinting toward this. I just slapped this together for the heck of it and am eagerly waiting to be proven right or wrong.
Okay, so anyway, on the Gem homeworld, Ruby and Sapphire originally couldn't stand each other. They were polar opposites and always bickered, teased, and argued with the other. Kind of like most couples (THAT'S FUNNY BECAUSE RELATIONSHIPS SUCK HA HA HA). But everything changed the day when the Diamond Authority rose to power. The Diamonds wanted to turn the Gems into a warmongering race, and they deemed Ruby and Sapphire too small to do anything and sentenced them to be executed by the following morning. While in prison, Ruby and Sapphire confessed that they didn't hate each other and the only reason they argue with each other is because of their own insecurities. They got talking and realized they actually have a lot more in common than they originally thought, to the point where they forgot they used to hate each other. Nothing like being locked up in a jail cell the night before being killed for some bonding, am I right? But anyway, one of the members of the Diamond Authority, Rose Diamond (yes, I'm taking that theory into account) helped Ruby and Sapphire escape, telling them that just because they're small doesn't mean they can't do big things. The two of them went into hiding, with only each other to count on. And in the morning, they became one. ...N-no, not like that. They fused into Garnet. A few days later Garnet got word that Rose Diamond was changing her name to Quartz and was going to find a more peaceful planet to live on alongside a group of other Gems that didn't agree with the Authority's cruel ways. Garnet caught up to Rose before she left and explained that she was Ruby and Sapphire, and that she wanted to go with Rose out of gratitude. And then we know the rest of the story, Earth, gem war, Mr. Universe, Steven's birth, yadda yadda yadda.
