Now, I still don't know enough about WK to leave any kind of really meaningful remark, but this:

He’s just licking the sugar off when he looks up to find Crawford crossing the street, and fuck if that isn’t the way it always is between them – Schuldig finally finding something that interests him and Crawford coming along to change the subject.

..is fantastic. That's the kind of description that grabs one by the throat.. a scant handful of words, and we have this deliciously clear picture of what this relationship is like. I love it.
