we never get to see a proper resolution for "naked idiot" - he barges into other character(s) lives, and by chapter seven or eight, he's effectively gone. At times author even suggests that he may not be real (this kind of storytelling device probably works for serialized works, when going back and rereading isn't as easy as for collected editions). That is, until chapter nine, when the reader fully gets to appreciate how broken a man he is - which is a result of not anything dramatic or tragic, but simply because of inability to give up. "To live is to choose, and choice is exclusion" - in the end you can only pity mysterious nudist, because his choices clearly drove him into a corner.
