Quote #4
Grace Turner was happy to take care of his laundry—how else, beyond hot meals, to show mother love when her only baby was twenty-three—but Robbie preferred to shine his own shoes. (1.8.17)
Grace Turner doesn't get a lot of screen time in the novel. As a parent, though, she comes off way better than Emily or Hermione or Jack.
Quote #5
Even being lied to constantly, though hardly like love, was sustained attention; he must care about her to fabricate so elaborately and over such a long stretch of time. His deceit was a form of tribute to the importance of their marriage. (1.12.6)
Emily is thinking about Jack's affair, and convincing herself that he cares about her because he's willing to construct elaborate lies about his infidelity for her. Who else in the novel shows they care by constructing elaborate fictions? Jack's youngest daughter, perhaps?
Quote #6
How could anyone presume to know the world through the eyes of an insect? Not everything had a cause, and pretending otherwise was an interference in the workings of the world that was futile, and could even lead to grief. Some things were simply so.
She did not wish to know why Jack spent so many consecutive nights in London. Or rather, she did not wish to be told. (1.12.7-8)
Emily thinks that imagination is dangerous and that it's bad for families. Briony proves her right, in some sense—she certainly messes up her family by "interfering in the workings of the world." At the same time, though, if Emily had had a little more imagination, and been willing to interfere a little more, maybe she could have prevented some of what happened?
