This was really the best episode of the season. I've been disappointed with this season for the most part, so it was really nice to end with such a well-written and well-crafted episode.
The writers have always done well with the war-related episodes over the years. Even years after the actual events it's clear that emotions are still raw and many of the characters have never really recovered from the horrors of the war that they experienced. This episode was no exception. Things are not always black and white, people are not always all good or all bad. There's a lot of nuance in this episode, something that was really lacking in most of the other episodes this season.
Loved the last scene (although I guessed it was coming).
