Okay, gem lived for thousands of years (as an alien) and I agree that they are of course intelligent.

But how did they managed to learn modern English, Do they have some sort of contact to earth until now, or they have some kind of language that understandable by all creatures in the universe? And do they understand the languages of every living being? If so, why does Pearl cannot control Steven's goat?

I know this all was only a cartoon, where everything can do anything they want. But I need some sort of logic here.
