Much like every other argument he had ever taken part in, ever, Regulus was feeling as though his opponent did not take him seriously. Which did not make any sense in the slightest. Though young, Regulus thought himself as a formidable and frightening person to stand up against; surely there should have been more fear in the man's eyes. Instead, he was strong, unaffected and had taken on a rather irritatingly mocking tone.
"I wasn't taking your blanket! I didn't think--know--I'm sure its not even yours to begin with!" He shouted in retaliation. "Probably just found it and decided it'd make a good addiction to the garbage castle you had assembled over yourself." Regulus scoffed and rolled his eyes, glancing elsewhere momentarily as he folded his arms over his chest.
A bubbling, whining sound echoed in his stomach, reminding him of the empty, aching abyss that was his hunger. This only furthered his frustrations. He had missed out on a golden opportunity to eat earlier that day all because of some wizard who had managed to play dead so efficiently it had scared him. And what reward did he receive for showing some human kindness and compassion? Accusations and disrespect. It was disgusting.
So, he continued his incredibly childish and ridiculously pointless tantrum. "Logical? We're speaking in terms of logic now, are we? I believe we're past logic! No logical man would bury himself beneath garbage. No logical man would make himself appear dead. Do you, do you know what happens to the dead here? Dogs eat them. Were you hoping a dog would eat you?" He threw his arms up into the air, flabbergasted by the very idea. "A logical wizard, with a wand!, would have decided on some other means of shelter. You have a wand! Put it to good use." It only made him bitter, seeing as he had to destroy his own and had not, since, been able to find a replacement. Or, at least, come close to finding one. Where did a person find a new wand, for that matter?
For a moment Regulus considered continuing his rant, but his mind and tongue seemed to be stuck on one thing. "You were dead!" And he could not get past that. "The garbage had more life than you."
