In the manuscript. "he went from one quarter to one half ethnic Arab' as the drafts proceeded" Riles's firsthand archive account

In the published book. Scene 7 (pp. 33–37; introduced at p. 33)

Evidence. A single source reports this. Documented by Riles's firsthand archive account (firsthand HRC sighting).
