You reform somewhere where it's pitch black. You can't see anything, and you fall into the clutches of anxiety. After an hour or so you hear a shuffle. You turn to face the noise, and you can make out a silhouette.
You begin to shake, unsure of what to do. You wanna get as far away from the figure as possible. The figure gets closer, and you can make out a few details. You gasp as you see a certain detail:
It's a gem.
There's been a slight change of plans with the new expirement. Instead of just observing it, you're supposed to mess with it. A new way of torture, as the Agate put it. You have the slightest bit of sympathy in you for it, but you won't let that stand in the way.
"Come on, you arrogant fools! Yellow Diamond wants this fixed up for when they find Rose Quartz!"
You quickly start to work before the agate starts yelling again.
"This might just be your big breakthrough..."
You mutter to yourself. And you begin to watch.
