Trivia: Although they didn't have any scenes together, Kevin McKidd (Vorenus) and Tobias Menzies (Brutus) would discuss their characters and brainstorm about how to portray them, because they felt their characters went through very similar moral conflicts. Confirmed by Kevin McKidd on the season one DVD commentary.
Trivia: Pompey Magnus had two sons that fought against Caesar: Cnaeus and Sextus. He never had a son named Quintus as is stated in the series.
Trivia: Atia's character traits on the show were loosly based on those of Fulvia, Marc Antony's third wife. Servilia's role in the conspiracy to kill Caesar on the show was inspired by that of Brutus' wife Porcia. Confirmed on the DVDs.
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.
