The code is "Sneople", obvs. (They never said it would be a number.)
Except, they still HAVE a body. They're sharing an experience. Like when Steven becomes Stevonnie. He's not GONE. He's experiencing life as a new person, albeit a shared one. He still remembers everything Stevonnie did as though he did it. Garnet's fused gems are not "Gem only". They're actively experiencing (and being) a part of something bigger.
I think Gem only can be a thing, but if so, fused gems should not count.
I agree with Fulgur14: Even the gem in the local lighthouse (apparently) wasn't discovered until Steven found it. That was RIGHT ABOVE THE TEMPLE. There's still a LOT of work left to do on Earth.
And how about the Cluster? Can it be healed?
Why is Homeworld broken in half?
Where did the Heart of the Crystal Temple come from? Does somebody want it back?
Why didn't Jasper unfuse from the corrupted green critter? Does she still have more healing to do?Are they permanently fused now?
I still want Cookie Cat to be a real character, but maybe he's just been foreshadowing all along.
Why do they have to be red? ;)
