"You think this is funny?" he questions, his voice strained. Does this man know who he is and what he's done? No, clearly not, but he doesn't want to bring that up. He's ashamed of his past actions. That's why... He takes a long breath and calms himself. He's now the Supreme Primarch, he can't lose his temper over this. Even if this man is irritating and vaguely reminds him of that idiot who resembles Lord Lucifer. "Is that your only goal? Entertainment?" He asks more seriously as if he's trying to gauge an enemy from some minor annoyance.
