Quote #4
I will never be in a profoundly messy situation with a boy, Jules Jacobson thought with an unaccountable little burst of despair. (7.166)
Jules is jealous of a girl who was probably just raped, because she wishes she could get that level of attention. We don't even know what to do with Jules anymore. Ugh.
Quote #5
Clearly she'd undervalued him, she thought now darkly, as she stood […] without a piece of silicon snapped deeply and securely inside her, […] waiting to be put to use. (9.26)
Jules only thinks she's "undervalued" Ethan because Ash is going out with him now—she's jealous of Ash and her relationship and her sex life. So much jealously despite repeatedly rejecting Ethan earlier when he expresses interest in her.
Quote #6
It was darkly fitting that Jules herself, who envied her friends so powerfully, would have an envious daughter. (13.120)
Rory may be envious, too, but she doesn't rival her mother one bit. Rory is a much-more self-possessed person, and as such, can't be as consumed with others as her mother is.
