Look at the reach on that dude! He can stand perfectly straight and scratch the back of his knee without bending. He can pick a pocket from the other side of the street. He can open a trapped chest from the next room. Who needs to climb walls when you can just reach up and haul yourself over the parapet?
I always wondered though, what's the deal with that little ringlet around his right bicep? Is it the captain's armband for some thieving competition? The last remnant of his shirt--the rest of it having been lost, along with his shoes, in a game of dice?
