Unless Nymeria and friends all travel to the Kingdom of Third Ward to get some dragon glass grillz put in their mouths, I'm not sure exactly what effect they would have against the undead and the WW.The Dog Lord said:bonfarr said:AG 2000' said:The other big battle episode is Ep.5 (Sapochnik directing), but otherwise a good theory.bonfarr said:
I have jumped on the NK to KL theory over the last 36 hours. There will be a massive battle at Winterfell that ends in a victory for the living but at a heavy cost and they learn the only defeated half of the NK's force. The NK will burn KL to the ground with his dragon and the other half of his army and then pivot towards the North.
Tyrion, Sam, and Bran figure out how to defeat the NK and defeat him in episode 6.
Perhaps what is left of the armies defending Winterfell regroups with reinforcements and make a stand in the Neck either at the Twins or Moat Cailin to halt the NK army's March North and that buys the Bran/Tyrion/Sam braintrust more time to plan and prepare like the Alamo did for Sam Houston.
If the NK to KL scenario plays out, it would also make it easier for Nymeria and her wolf army to join a battle that would occur closer to the riverlands (assuming the survivors of the BoW march south).
