Leaning on another brick wall... by @Worm (Chris Watson)

Well, it would seem from artistic sources that Marko does little other than loiter by brick walls looking suspicious. This isn't strictly true. He can also be found stealing cars, applying obnoxious tags to any available surface, making off with your wallet or cellphone, or reducing the wealth of local sportswear emporiums. But other than that, he's a really nice guy. Honest. Oh, and the creepy-looking guy in the robe is his spirit mentor, who by all accounts ISN'T a really nice guy. At all.
