Final answer:
The excerpts appear to be from a literary work, with characters expressing reassurance in tense situations. They deal with issues of trust, impending actions, and the roles characters play within the story.
Step-by-step explanation:
The dialogue snippets provided seem to come from a work of fiction, likely to be from a play or a novel. In both excerpts, the characters deal with situations of trust and reassurance during strenuous or crucial moments.
For example, the first excerpt begins with a character named Belling reassuring another character, Niki, that there's no need to feel terrible because she remains the understudy to a character named Georgia.
Similarly, the second excerpt involves a character seemingly confronting another about the truth, possibly implying a situation that may have caused doubt or worry.
The response seems to suggest that someone named Niki won't need to feel terrible because they will still be the understudy to Georgia. The blank might be filled with a response or continuation that comforts Niki or explains why they need not feel terrible despite the situation. For instance:
"Don't worry, Niki. Your talent shines, and being the understudy to Georgia is still a great opportunity."
