Well, you knew the production was going to be a success, so there's no surprise for you there.
"Vissi d'Arte" is actually one of the most lovely arias in the entire soprano repertoire; done right, it's all but guaranteed to bring tears to the eyes of even the most jaded listener. So you can understand Nick's reaction on stage. For those readers unfamiliar with opera, audiences typically interrupt performances after major set pieces-arias, duets, trios, etc.-with applause and cries of "bravo," etc. The conductor will ordinaily wait a reasonable interval for the racket to die down. And mostly the audience will quickly subside once the orchestra resumes (attending operatic performances is a real exercise in courtesy all around). By the way, "bravo" is usually reserved for male performers; you properly shout "brava" for a female, while "bravi" is for two or more regardless of gender.
The show's over, but the night is just getting started for Nick and Camilla. And for Asmedogh, too; I know he hasn't been very prominent in the story lately, but I really haven't forgot about him.
