Quote #7
A few weeks after Mrs. Lisbon shut the house in maximum-security isolation, the sightings of Lux making love on the roof began. (4.1)
Every prison has a black market, even Mrs. Lisbon's Home for Suicidal Sisters. Lux manages to find some way to signal to randos to come visit her and takes them up onto the roof for some loving. It's a very public place; all the neighbors knew about it, but her jailers, her parents, have no idea. But Lux is still emotionally isolated; all her lovers comment how remote she seemed during sex.
Quote #8
Following the Homecoming dance, Mrs. Lisbon closed the downstairs shades. All we could see were the girls' incarcerated shadows, which ran riot in our imaginations. (4.2)
The use of the adjective "incarcerated" to talk about the girls compares their home to a prison, which is what it must seem like to them as young people trapped in the house. In fact, the narrators call the girls incarcerated "shadows" as if they were no longer real people to the rest of the world. They're total unknowns now.
Quote #9
The house receded behind its mists of youth being choked off, and even our own parents began to mention how dim and unhealthy the place looked. (4.9)
As the girls dig in at home, even the house begins to look depressed—unhealthy, neglecting its appearance. "Youth choked off" is a powerful description; it seems to foreshadow the girls' death.
