It seems to me he's been through the biggest emotional rollercoaster of them all. Being accused of game-playing and manipulating. Being involved in most of the drama, whether it be mediating or being attacked in some way. The whole environment seems to have braught him to a minor mental breakdown from what I can see.
I think he has literally taken in everyone elses feelings and emotions in order to try and process, fix and put people back together. Except that never works in reality. By entertaining peoples negative behaviour you end up being braught down to that level.
