They don't seem to be into the Direwolves in the show. CGI costs too much and they don't seem capable of using perspective to make a normal wolf look much larger so they are killing them or avoiding having them around. They must plan on Nymeria being useful later on to have spent the money on this appearance.
Anyone else concerned that Littlefinger might send a raven to Cersei divulging Jons journey. They're going by sea so Urine could grab him.
I hope Tyrion knows some way into Casterly Rock. Seems pointless to attack if he doesn't. When Tyrion was Hand, he told Vary's that Jaime was in the Kingsguard, Cersei was Queen and he was put in charge of drains and cisterns at Casterly Rock. Didn't the unsullied enter one of the slaver cities by the drains?
