Mario's Bolex walk and Avril on sadness (pp. 769–770)
Out the right to the north over lots of different lights is the red rotating tip of the WYYY transmitter, its spin’s ring of red reflected in the visible Charles River, the Charles tumid with rain and snowmelt, illumined in patches by headlights on Memorial and the Storrow 500, the river unwinding, swollen and humped, its top a mosaic of oil rainbows and dead branches, gulls asleep or brooding, bobbing, head under wing.
Context
The scene's closing pan out Avril's window ends on the WYYY transmitter — Madame Psychosis's station physically present on Mario's horizon as a rotating red light, its spin doubled in the Charles. Mario, WYYY's most devoted listener (093's vigil), is the viewer here — his "gaze keeps going from Avril to the window behind her", hand ready on the Bolex's treadle "if necessary"; the radio thread and the optics thread meet in one reflected beacon.
