Well as far as the swapping from Eagles to JHatty thing that had nothing to do with role, but he does keep his mouth shut every time he's evil and hopes nobody notices. Once someone pointed it out it seemed like the obvious move.
As far as my role goes, I was sitting on it because I'm the Doctor. Healed myself night 1 because Devise has a habit of always nailing me on night 1, and if he was a killing role I just didn't want to get killed on night 1. Night two I sat on it and last night I sat on it because we had no obvious targets. If we're getting all the roles out that'll make things a smidge clearer for me
