After what is over?

"Of course we don't normally all live together. The war and blitzes have brought that about - but I don't know -" she frowned reflectively - "perhaps spiritually the family has always lived together - under my grandfather's eye and protection. He's rather a person, my grandfather. He's over eighty, about four foot ten, and everybody else looks rather dim beside him."
"He sounds interesting," I said.
"He is interesting. He's a Greek from Smyrna. Aristide Leonides." She added, with a twinkle, "He's extremely rich."
"Will anybody be rich after this is over?"
"My grandfather will," said Sophia with assurance. "No soak-the-rich tactics would have any effect on him. He'd just soak the soakers. "I wonder," she added, "if you'll like him?"

Q:Why does the writer make the character say whether some person would be wealthier after what is finished? The context seems not to tell us..

Will anybody still be rich after the war and blitzes are over?

Would that help?

Chileno already provided the answer.
The speaker's grandfather won't necessarily be wealthier, he just won't lose the wealth he already has as a consequence of the war and blitzes.

Thank you~
