Continuity mistake: Pullo has a hole drilled into his head after his return to Rome, yet in later episodes there is no visible scar, even in scenes where his hair has been shorn.
Continuity mistake: When Vorenus ask Eranus where his children are, Vorenus raises both his arms. When it cuts, they are down.
Answer: Its Pullo's nature to resent people of higher standing than him. His jealousy of Vorenus in later episodes, which in part leads to their falling out, is proof of that. From Pullo's point of view, Vorenus just got better breaks to get where he is in the army and so, isn't really his superior. That, plus his natural arrogance is explantion enough for his behaviour in spite of the fact that he broke the rules and was being fairly punished.
