So...you're from the Gem Homeworld then?

[Because that's certainly what it sounds like to him all things considering. Maybe there were Gems that had the same kind of gem? There was still a lot he didn't understand about gems and their race, so his guess was as good as any.]

It's nice to meet you Amy! And you meet Pearl and Connie too? Do you know where they are??

[Because familiar faces would be great right now! No offense to Amethyst two.]
