Me: your brother says you're an alien
Kilobyte: I'm not!
Me: how can I be sure?
Kilobyte: my blood isn't green
Me: that's true; I've seen your blood and it's red. Do all aliens have green blood? Or do they have all different colors?
Kilobyte: all different colors. And it floats. My blood just drips.
Me: alien blood floats?
Kilobyte: yes. And they're gooey like jello. *scratching him ear* and they don't itch. And I can't pull my skin off.
Me: aliens can pull their skin off?
Kilobyte: yes! Because it's a disguise!
Me: over their own skin?
Kilobyte: uh-huh. Which is all gooey and their blood floats around in it. And it's all different colors. In my imagination. *after some thought* but I think it's against their nature to disguise themselves as a human. They would rather use their technology to gather information
