Real quick mini rant and an omission that will make me rage:

Spoiler:
One of my favorite parts of The Red Wedding build up is how Grey Wind senses the impending betrayal by the Frey family and growls at a few of the Frey men when Robb arrives at the Twins. The Direwolves have barely been shown this season, and this would be one of the last times they will be able to show him and it's immensely important to the story. Robb didn't keep his wolf close and it cost him dearly. I understand that the budget went to the dragons this year, but this needs to be shown.
