This one’s a tough one to make predictions for… Unlike Garnet, we can’t see the future.
Still, we can make an educated guess about Garnet’s future vision: it can’t be all that good. Using just Warp Tour as an example, it wasn’t enough to see Steven’s death in the warp more than a minute before it happened and it certainly wasn’t good enough to see Peridot coming.
She has heightened perception, so hopefully we’ll also hear a bit about that. The question on everyone’s mind though, that we rather doubt we’ll get an answer to: what’s up with Garnet’s third eye?
