Even now, Aza still sees herself as being made up of multiple identities, though not all of those identities are visible (as evidenced by the solid nesting doll metaphor). Daisy's story suggests that Aza is an uncountable number of identities, and further, that trying to count them is a futile exercise. For her, simply realizing that there maybe is no "clean self" or solid nesting doll allows her to become comfortable with the chaos inside her mind. This mirrors Malik's statement about science: it just makes more questions, which isn't a bad thing.
