I think Ed knows that deep down he is the most likely one to go this week and thats why we are seeing a more nasty side. That tied in with the fact they've been in there for weeks now and are all probably going a bit crazy. I personally think he's the typical guy who was handsome and sporty all through high school and feels self entitled now in life due to his "popularity" and the way girls fawn over him and guys respect him. I ALSO think its time for a reality check and hes got to go!
