[Alright, so this huge thing can talk. Good! For a moment, Rose thought she might have been trying to address a mindless machine, rather than a living being.]

I can't say that I've ever heard of you or any Decepticons, no. Chances are, this space is entirely different from the one you're familiar with.

I'm the leader of the Crystal Gems, a group dedicated to protecting humanity. Most of the people here aren't from the same reality that I am, and I've been separated from the rest of my group, but my mission is still the same. I just need to know if you pose a threat to the people here, that's all. I'm sure you understand my concern.
