Hello guys, i'm not going to make any theory in this post, i just saw something strange in the promo of the 8th episode so i made this screen capture here http://i.imgur.com/LBmQm0R.jpg and as you can see RED JOHN has a little quantity of white hair (or not) and a head like ball.

PS: We're not sure all the suspects who died are really dead ;) 

so.....
