Mario's Bolex circuit; Avril on sadness (p. 763)
Tycoon is the term her commanding way of sitting suggests, grasping her chair, a pen clamped in her teeth like a businessman’s cigar. There were other carpet-prints in the heavy shag. […] Some of the prints in the deep shag he can see are shoes, and some are different, almost like knuckles. His lordotic posture makes him acute and observant about things like carpet-prints.
Context
Mario, camera off, in the Moms's blazing-lit office at night, asking how you can tell whether somebody's sad — and twice the narration drops to the carpet: prints in the shag that aren't shoes, "almost like knuckles." Never explained, never mentioned again; filed with the brooms as the office's things-that-don't-add-up. (The digest keeps a non-wraith reading live too: the prints sit suggestively near the Avril–Wayne staging details of p. 552. Unexplained either way.)
