Later, much much later, I asked Zarfa what had transpired during Natha's delivery service that day, and she told me as such:
They were in the usual hotel, and since I informed Ignis that Natha would be the one coming, Zarfa did not put the token in the bedroom--naturally. She placed the token in the room we used as a strategy/meeting room, where Natha appeared later in his guise.
Wonderful. How dare they see that appearance longer than me? Anyway...
The delivery service was superb. Shiny jumped off safely--if not slightly terrified. But that was normal since Shiny did not have immunity to Natha's fear. Nor the other humans. Zarfa already knew what a silly lover boy Natha was from his doctor days, so she bypassed the fear wall. Aina...was just fearless.
