#though I'm also OBSESSED with Shark's take that John uses them pretty 'normally' but in ways that are at odds with Arthur's demeanor

I love to imagine how exactly John might use Arthur's eyes that's so odd; both the policemen at the lighthouse and the Butcher on the train note something unusual about his gaze. Does John look at things for the "wrong" amounts of time? Move his eyes in unusual patterns? Not move his eyes much at all, using them more like clear windows?
