I'm about 99.9% certain that in the original BG2, after Kalah breaths his last breath in the circus, there would be a dialogue exchange between Aerie and Quayle in which Aerie would exclaim, "Uncle Quayle, you're OK!," and the two would then tell each other how each had "changed" the other during their time together, and Quayle would then wish Aerie good luck on her new adventures.
However, as you can see in the picture below, this doesn't happen in my game - instead, Aerie turns around as if to initiate dialogue, but then no exchange actually happens.
Is this a bug? Or was the exchange deliberately removed by the devs, perhaps due to all the complaints about lack of continuity between BG1 and Quayle's story here?
Also, if this is a bug, does anyone know whether something like this would affect whether Quayle's "helping an old friend" quest will trigger?
