One note that I was sort of bummed wasn't in the episode. When Stannis sees the Tyrell forces, most importantly a man in Renly's armor, it would have been cool if he whispered "Renly...?" in utter disbelief. In the book, the Stannis forces are routed in part because they flee, thinking Renly has risen from the dead. It turns out to be Loras Tyrell's brother Garland in the armor, who is considered one of the three men in the realm capable of holding their own against Jaime Lannister in a fight. Of course in the show, it's Loras in the armor which is fine since Garland hasn't been introduced
