Overture Downs We operate under

You overestimate what people have asked for.  People have simple desires when the days get darker and prey gets scarce.  She wouldn't tolerate outlandish desires, let's be real -- Arbiter's whole attitude didn't exactly condone Disneyesque song and dance daydream sequences or anything.  But at this point, she was done offering Sarah a blank check -- if she was going to be that obtuse, then fine, she obviously didn't want anything badly enough for things to change.  If she was going to complain later on about not being rewarded or showered with honors or whatever, it was her own fault, as it wasn't like Arbiter was dancing around the subject.

Aside from the silent fact that Sarah was managing to wear away at Arbiter's opinion of her, she was also tiring of this loop of a conversation.  Loyalty could shift, yes, but that had been what she was trying to fix, was it not?  Instead, it was the opposite reaction, somehow. Give it a few months and those that are particularly fickle will be reconsidering their choices.  They were probably near their destination now anyway, and soon there would be things to investigate.  It didn't seem like they were going to come to one single answer to this discussion, as they must have had very different experiences in the world.
