For now, Lily seems totally uninterested in giving Travis the time of day, but Daunis still feels compelled to protect her friend and make sure Travis doesn’t continue to push Lily. If Travis is insisting that he’s “clean,” this means he’s likely struggling with drug use or addiction of some sort. Still, Daunis seems to sense that Travis doesn’t care about getting well because it’ll make him healthier and happier. His goal is getting Lily to agree to get back together with him, which leads Daunis to question his commitment to getting and staying clean. Modifying one’s behavior for someone else, in other words, isn’t something the novel suggests is the best, most motivating reason to do so.
