A shot of Renly and Catelyn walking through his camp together, probably before the conversation concludes. The golden, prancing stag on green makes for a nice banner, certainly. Bear in mind that in the novels, though, Renly never takes that as his personal heraldry: he retains the traditional Baratheon arms for his banners, even though he does adopt green-and-gold (both a reference to the Tyrells and simply because he was fond of green) in other places.
