Final answer:
The question seems to refer to the wrong play; Walter and Lindner are not characters in the provided text from Henrik Ibsen's 'A Doll's House'. Without the proper context, an accurate and specific answer cannot be provided.
Step-by-step explanation:
It seems there is a mix-up in the question provided. The characters Lindner, Walter, and the scenario referenced do not align with the excerpts from the provided text, which relate to Henrik Ibsen's play A Doll's House. In Ibsen's play, there are no characters by those names, and the provided text refers to interactions between Nora, Mrs. Linde, Helmer, and Krogstad.
It is likely that Walter and Lindner are from a different work of literature, possibly Lorraine Hansberry's A Raisin in the Sun, where Mr. Lindner is a character who visits the Younger family, and Walter tells him about their plans and dignity. Without the exact contextual details, however, it would not be accurate to provide specifics of what Walter tells Lindner. If referencing A Doll's House, we should be discussing the dynamics of Nora's realization and the transformation in her relationships as she navigates through 19th-century societal expectations.
