So has nobody noticed the faint scar on the MiB's left cheek which just happens to be where Dolores slashed Logan in episode 9? Also, Logan was the one who cut Dolores open to reveal her mechanical insides. Even though William says he finally understands how to play the game in the end, he kills and dismembers the soldiers in the camp only after Logan slices Dolores open. I know their coloring off, with Logan having dark hair and brown eyes and MiB having light hair and blue eyes. That's been one of my biggest sticking points, but I just don't quite buy that William is really MiB.
