Here's a familiar face. Yes, he's familiar with a rhetoric question, but it's not it specifically that causes him to pause and address the child. He happened to be passing by when he heard her grumbles.

"Would you like me to explain? I can answer your questions to the best of my ability."

It's the confusion that brought him to stop. There's a lot being talked about and quickly. And it would be better to offer an opportunity for the child to better understand what's going on than have her swimming around and unsure where she can best put her talents.
