Tom son of Tom

I don't know who that is. But after a google search and seeing his image, he is indeed in this episode. We catch glimpses of him when the NW meet Craster outside, and when he looks up at one of Craster's wives

I think that scene was more about the showing the innocence of the Lannister hostages.

This.

It would have been awkward to me if Locke's men had not sung it earlier in the episode. I can understand why it felt weird to some. It was ok to me, but I would have preferred something different.

9/10. I loved every bit, particularly the Riverun scenes.

Jaime has been tied up and held captive for a long time. I don't think it's that unlikely. We saw Brienne defeat Loros last season so we know she is a good fighter.

7/10 I had a feeling they were gonna skimp on the battle at the Fist. Other than that the episode was fairly strong. The Tyrion/Tywin scene was amazing. Great acting.
