Dawn’s death is what inspired many of the characters to give up heroin (although not other drugs), and so Dawn’s absence hangs over much of the rest of the book. On the one hand, Dawn, like the dawn of a new day, the possibility of hope and rebirth. But so far, most of the characters seem to be acting about the same as they did when they were on heroin. Nevertheless, when Rent Boy addresses Spud by his real name, it suggests a moment of growth (and perhaps Rent Boy’s realization that while Spud is mostly a good person, his other friends might not be good people).
