I loved finding out more about Mr. Eko. One of the best things about this show is how none of the characters are what they appear to be at first glance, and this was another great backstory.
How maddening that we don't get to see what Computer Walt was typing to Michael at the end of their conversation! And I was really disturbed to see Charlie had been stockpiling Virgin Mary statues.
I was really disturbed by Charlie's drug stockpiling, too. When I was watching it, hubby thought he was taking the statue into the woods to pray and when the camera showed his little stash we both were really surprised.
I'm not sure that Michael is really talking to Walt. I wonder if it's a trick.
