Sora is going to have to run that through his head twice. Okay, so this is a Pokemon, who can be owned (??) by a human, but it's the only? Pokemon? The only Pokemon? Wait, but there's more than one Pokemon. That's what they said, right? So, there are multiple kinds of Pokemon, kind of like how there are animals? Oh, so that's why humans can give them names. It's like how you can name a cat or a dog!

Sora gets about this far in his understanding (literally, fingers out, trying to keep track of all of the points Mewtwo just threw out there, it's not great) when he registers that Mewtwo asked him a question. He shakes himself! "Wha-? Oh, um, my name? I, uh." Sora shakes his head. "Stuff happened. So you are a Mewtwo, and want to be called Mewtwo? Sorry, I'm gonna circle back, I'm just kinda stuck on your name right now."
