I really like this episode, I dare say it's underrated, it showcases a lot of the things I came to love about the show, particularly the way they start to connect the threads of the story and it start to all makes sense, there is also clever writing around the twist you only notice after you know what it is, there is also a surprising amount of heart and the scene between Mike and Coulson when they discuss his future got me teary eyed, with hindsight it is even more powerful.
