I absolutely love this series. I've tried in the past to get a sense of the disciples, but everything I have found was so academic! Seeing this makes me feel that much closer.
As I relate to people within my own life I tend to try to gather understanding from looking at the "background" of their lives. I am also an artist, so I watch literal backgrounds as well. Within Episode 1 of Season 2 there were a couple of background distractions. One was the man passing behind Thomas as Ramah's father was leaving. He passes 2 times in exactly the same way. Also, when James and John leave the room after being voted down. James is dressed very differently when he gets outside.
