As that scene evolved, I really expected they would have Sam kill him with the obsidian knife. Instead he just stared at him. Was he too craven in his eyes and not even worth to kill? What do you think the writers of the show want us to think of this? Or is it just the only way to show their army closing by through the eyes of one of the characters? Another small thing; in the books there weren't even white walkers attacking the fist of the first men, there were just wights. This made a lot of people think the white walkers were very few in number. I'm also very excited for what will happen next, I hope they show us the battle at the fist!
