[It hasn't been all that long since he was- created, but in the time since his existence came to be, he's had the opportunity to learn quite a few things. Ignorance would have made him less useful, naturally; what else was there to do whenever he wasn't training and getting stronger?

If he were the type to laugh, he might be laughing right this second. The stranger's reasoning is almost enough to take him by surprise, because... seriously?] That's the dumbest reasoning I've ever heard. Just because you're nicer, doesn't make you better or more suitable for ownership. Kind of like how being a good person doesn't make you stronger.

Okay, being all-but-ignored isn't going to fly with him; the guy's sitting down instead of so much as responding to his threat.

While he doesn't look concerned over it, there's a ghost of curiosity.] How does that make me too late, huh? Not like anyone can even see that with all the hair in the way...

[Ugh, they even have annoyingly similar hairstyles... Maybe he should take some scissors to this... Sora's hair whenever he's sleeping.] ...

Hero doesn't give you too much trouble. [The next sentence is said almost in a whisper.] I don't think he's as bad as he seems.

[An annoyed growl slips from his throat as he looks over to see the fuzzball flying over to shake Sora's hand.] Keep that up, and you'll be turned into dinner.
