Okay, I started thinking. Why is Henry always smirking? Yes, it's an obvious indication that he an other, but isn't it always in private? If so, what does that really say to us? Is he happy that he can manipulate the losties? Is he pleased that the "experiment" is going as planned? Does he just enjoy getting back at the Losties for beating him up? Is he a rogue other gone crazy? or is he just smirking to freak us out.
