Wisteria Young Ladies' Seminary

[imchongjun]

Hello, teachers.
I have a question about the following dialog.

"You won't laugh or make fun?"
"I promise."
"I'm a schoolteacher," Janet whispered.
Doan looked shocked. "No!"
"You promised!"
"I'm sober as a judge," Doan said.
Janet said: "I'm a schoolteacher in the Wisteria Young Ladies' Seminary."
"Now, after all," said Doan.
"It's true! There is such a place, and I teach in it."

I think Doan's "after all" means "after all you were lying", but why does he think so? Is "Wisteria Young Ladies' Seminary" such a strange name for a school?

perhaps Janet had doubts about teaching there earlier.

"After all" means "in spite of considerations or expectations to the contrary", so in this case it is used to express surprise, could be both because Janet is a teacher and because the name of the school sounds strange (at least to Doan).

Thank you everyone. You are always helpful.

Probably means the same as "Gosh" "Is that so?" or "I'd never guess"
