A few weeks ago, Milk Man said believed the hooded guy behind Connacht in the comic book was The Faceless Man. But if you look closely, you could see the hooded guys' eyes, nose, and yes, mouth. Also that couldn't be Mazzarin, because after he died he most likely turned to the dark side, not joined up with Connacht (but you never know!).
But I do believe that Mazzarin is The Facless Man, at least I believe he became a Fallen Lord, and I got a theory about it that I will be posting up later this week, :) Thanks for the info guys!
