I love the reveal that dr. edwin jenner opens the door in the last episode. the thing I also love about this episode is the way the group react to having warm showers and electricity. it shows how they are not just killing machines and that they do have a personality. I also like the way that at the end of the episode when amy wants to stay to die but dale risks his life to save her. that is one of the reasons why I love dale. he was such a kind character who tried to stop people dying by just talking and not killing unlike like everyone else and that's what made him a good character.
