Amazing episode, and the airlock scenes just exemplifies why this show is so good. Good, well written, likeable characters, each with their own unique individuality. It's immensely satisfying to know the words and actions of a character before they say or do something, but I knew exactly what was happening in that scene, and it was great because of it.
This is the best thing on TV at the moment, and I dare say I enjoyed that episode almost as much as any Game of Thrones episode when its at its best. It might not have the production values of the likes of Westworld, but I'm enjoying this more currently. It just keeps getting better.
