I'm assuming Sadi was aware they were talking to a fae XD

And given that fae tend towards somewhat insane by human standards, whatever came from this I'm sure Clever Hanz probably just found more interesting/entertaining than anything else unless Sadi did stuff to make them regret it down the line, which I guess is a thing that could have possibly happened given that you included Clever Hanz in the would not have done it if they'd known XD
