Joelle's Too Much Fun at Molly Notkin's party (pp. 236–240)
She produces a double rose of flame in the mirror that illuminates the right side of her face as she holds the tube over the matches’ flame and waits for the stuff to begin to bubble. […] Her unveiled face in the dirty lit mirror is shocking in the intensity of its absorption. […] pulls her face up to face the unclean medicine-cabinet mirror, twin roses of flame still hanging in the glass’s corner, hair of the flame she’s eaten now trailing like the legs of wasps through the air of the glass she uses to locate the de-faced veil and what’s inside it
Context
The bathroom mirror runs through the whole cook and overdose: it doubles the match-flames, catches her unveiled absorption, and at the end is the instrument she navigates by. Carlisle's reading — recorded, not adopted — is that Joelle unveils "before the mirror that illuminates," the rapacious encaged self set free in front of glass, the private inversion of Melinda's public mirror out in the living room.
