So okay I've mentioned this before but I love it enough to talk about it again. He is blind, but his other senses are enhanced to a superhuman level which allows him to "see" by using his sense of smell and hearing to figure out exactly who someone is, what they're carrying or doing, and where they're coming from. Whenever he is out on patrol he listens for ongoing incidents or crime and when he does this, his head tilts in this really adorable way towards where the noise is coming from or away from it to figure out its exact location. I notice it every time when he does this and it's one of my favourite details because it's so cute and unique to him.
