This sort of confused me as well because Matt said about him 'blind like me, well not exactly like me' and my first thought was that this meant 'without enhanced senses' rather than e.g. 'blind from birth' which doesn't seem like an important distinction at the moment he's talking about that but on the other hand you can train as much as you want normal human senses have limits so if anybody can shed light on that and on what the hell Matt meant by that I'd be very grateful XD
