In this story (not just this chapter, although it is one of the main Xander-centric ones), the exposition of Xander's world view, his pain, his insecurity, his way of trying to deal with being a young adult who has never had a good role model, is very sympathetic; it makes us understand his motivations for his noble and less than noble actions in canon and in this story. I really liked how she handles the inner thoughts of all the characters, but she does a particularly fine job with Xander and Anya (poor Anya).
Love this bit:
"He was brave and loyal and simple. He took everything like a body blow; he didn't have it in him to shrug anything off. A person had to be elastic to do that, and he wasn't. Everything was personal. Everything mattered."
