Dat Ass.
No one's ass in particular was the subject of the Redcap's toothy too-wide grin (and it was too wide, like a shark's), Mark wasn't a connoisseur or anything, and he wasn't meaning to leer too much, it's just that sometimes it seemed that the Lost came in two flavors - Gorgeous and Ugly. Mark Flay, Ogre, Redcap and general lowlife, got plenty of ugly in his mirror everyday and it wasn't like he was beating the prettiest mortals off with a stick. In his opinion, there wasn't no harm in appreciating some high quality physical beauty when you were surrounded by it.
Mark wasn't dressed all fancy. Blue jeans and a flannel shirt in red, his heavy boots, they're clean and ironed though, which (I guess) is fancy for him. Got to put your best foot forward at one of these things, right? The heavy material kept him warm too, which wasn't something to be disregarded when it came to winter.
