See, additional scenes when they're simple and to the point are perfectly fine. Seeing Theon learn of Robb's death, and his broken nature with continuing to shave despite being tempted to slit Ramsay's throat in that moment say everything that needs to be said.
Slightly subtle symbolism! Hodor's voice comes out of the deer's mouth, which to me speaks of how Bran's warging might be consuming Hodor's when he takes him over.
As the last GRRM written script I can't help but that a lot of attention is paid to small details and respected with a lot of good reaction shots from different characters.
