First couple of episodes will be introduction of new characters, Red Viper, etc. 1-3 we'll see Dorne's impact on the politics of KL. 4 for the PW, 5-6 for reactions to it, including Davos sending Gendry off to protect him from Mel, and then reading the letter from the NW and convincing stannis to save the realm. Viper's Duel in 8. I believe the battle of the Wall will be Episode 9, ya know with stannis coming in out of left field to save the Night's Watch. This will Mirror up to S2E9 Blackwater very, very well.
Crossbow in 10 as the cliff hangar for the season.
