I was just um, kind of dissapointed? It was yet another clickbait. I was hoping to see how Gems are "harvested" like what Peridot mentioned right when she was fred from the bubble, but nope, we got racist uncle.
Atleast he comes in handy during the Zoo arc. Gem Harvest could have had another title and an actual episode about gem harvesting could be called Gem Harvest instead.
I didn't really hate it though. Just mild disappointed, I could still enjoy it.
