So many characters, the loss of one makes little difference. I was upset at the death of the Hound.
Araya left the Hound up there in the hills , but did you actually see him die?
He was in bad shape, but me thinks he may not be a goner. Many characters that we assume are dead, we never actually see being killed.
Remember the swordsman who instructed Araya when she had the wooden sword? He was rushed by the King's Landing guards, but we never saw him killed. Some of these characters we could see again.
