Human-Ramnuan Communication

A Stone In Heaven.

When Banner speaks, only Yewwl hears her. (I, p. 9)

Banner sits before the screen and touches plates on chair arms. (VII, p. 124) Flandry sees the screen over her shoulder so it is not in her helmet as I had thought. It shows Yewwl's hand and a room occupied by two other Ramnuans, male and female. Banner addresses Yewwl. The male is said to react to Banner but how can he if she is audible only to Yewwl? OK. He reacts to the fact that Yewwl is visibly reacting to something, which happens to be Banner. By speaking deep in her throat, Yewwl can address Banner unheard by anyone else but she must explain to the other Ramnuans what is happening because she is visibly agitated, pacing back and forth in response to Banner's requests.
