"No," Piedra said, dusting himself off after he was rudly shoved, "I'm a sterotype thief here to steal all your crap, idiot," Piedra would clearify. He wans't here to be friends or to learn something amazing about some lost man deep underground. No. Piedra was here for free stuff and free stuff alone. Unfortunately for Walter, that free stuff weighed more than Walter's life.
"I am Piedra, the greatest thing on this planet. Ya should be happy to give me everythin' I want," Piedra proclaimed, speaking as if it were obvious. He would shove Walter right back, a gruff and heavy shove that was intended to, possibly, make Walter stumbel again.
"So hurry up! Ya aren't gonna make me wait, are ya?". No. Of course he wouldn't make Piedra wait. Because Piedra was a godly like, beautiful, powerful creature that deserved everything he wanted and was never, ever wrong. He was a creature that was undeniable. This man should feel honored to be in Piedra's pressence. So honored he'd give all his stuff before bowing down and eating the glorious dirt Piedra walked on.
