Keltham's roving eyes light on Carissa's armpit hairs. Civilization has mastered biochemical control of hair; Keltham himself doesn't have hair anywhere he doesn't want to. Most women of dath ilan do elect to switch off hair in armpits; Civilization tries to avert certain kinds of status-appearance contests that can only have a few winners and many losers, but everyone getting a simple treatment to choose their hair pattern is hardly that. He - does see why women would choose that, now? It doesn't look good on her, in his own decision and choice.
Keltham reaches down, wraps a single long armpit hair around his forefinger and pinches it between his forefinger and thumb, and then rips it out.
