Hmmmm. Maybe the black part on the mask is supposed to represent the dark Deathstroke part of him and the lighter side represents the good Slade Wilson. In the Pilot, the arrow was through the dark side of the mask. I think this means that Oliver will have to take down Deathstroke by taking out the dark side or the side of his face where the dark part of his mask is.
