"...You don't know what a tank is?" Porky repeated, a little confused, "But I thought that all this stuff...modern stuff, I mean, was ancient technology in your world! Eh, whatever. Lemme try to explain...a tank is...it's like a...big metal box with wheels. Bigger than a horse. Probably bigger than two or three horses, but that really depends on the size of the horses, I suppose...but that's not the point! The point is, tanks are absolutely deadly on the battlefield. They're almost impervious to normal weapons because of their thick armor and then they have a cannon attached to them. The rounds they fire explode, even!"

"What I'm trying to say, Alita," Porky said eventually, "Is that you're tough. Tough enough to protect Hokuto. You shouldn't worry so much about her getting into trouble. And 'take a chill pill' just means calm down."
