Final answer:
The given quote "Don't do this now, Sam - I don't want to hear this now..." does not appear in the provided excerpts, and there is no character named Sam in the dialogue, so it's not possible to accurately attribute the quote to any of the given characters.
Step-by-step explanation:
The line "Don't do this now, Sam - I don't want to hear this now..." is not found in the excerpts provided, suggesting it might not be from this specific script or conversation.

In the context of the script excerpts, the characters engage in various emotional and tense dialogues, but without the precise quote or a character named Sam, it is not possible to attribute the line to any of the options provided: a) Donna, b) Sophie, c) Bill, or d) Harry.
