Some people in Westeros fight with swords, but others use their words and their wits. That isnt more evident then the storm of snide-remarks that brews between Cersei and Lady Olenna in this episode. Every word uttered between the pair is a part of a thinly-veiled scheme, or a non-veiled insult. The Queen of Thorns may deliver the spikiest remark (the tart Queen Cersei) but it is Cersei who ultimately gains the upper-hand in what is the best battle of the episode. Hopefully therell be a rematch.
