"Your species doesn't live very long, five thousand years is more than enough time to forget things." Lapis gives a small wave of her hand. "Everyone's from different places though, and since I don't know of any humans fighting against aliens that aren't Gems where I'm from, it's probably different."

Besides, she's not an aggressive invader anymore. Earth is her home now, even if she's still adjusting to it. Or had been, before she'd been swept off here. "Besides, last I remember your kind was still living in mud houses. No offense, but fighting off Gems requires a little more technology than that." Granted, she's still got the whole Organic Life Is Beneath Gems down.

It's an unfortunate Gem thing.
