What did Scout keep asking Dill about that finally made Jem tell her to hush?

Scout was asking Dill where her father was. At first she said,"Where's your father?" Dill replied, "I don't got one".

Scout pushed on, "Well is he dead?"

"No he ain't dead", said Dill.

"Well if he ain't dead then you got one, don't you?"

It was at this point that Jem told Scout to hush up.

(Pretty sure the quotes aren't exact I haven't read the book in a while)
