Answer:"Not at all. There is a very simple explanation, Harry..... This must have belong to Hans" will not be considered a leap of logic.
Explanation:
This was said by Lidenbrock in jest since he was comparing the Hans size with others. Lidenbrock has no idea on Hans since they met only on the idea and he wanted to mock him for replacing his son.
