Ian listened to the professor's responses. He had seemed rather pleased that Ian had complimented his mother, but Ian's head drooped a little when Professor had said there would be no one leaving the room. Did that mean no one would be getting nutella? Ian thought to himself. He raised his hand and asked, in a rather wobbly, slightly weepy voice, Professor, you gave out chocolate coins, but I have an allergy. Why can't we get some biscuits to go with our nutella? Ian looked around for the nutella and was disappointed when he didn't see any.

Ian heard the question about gassy planets and was quick to answer, Perhaps their digestive systems can't break down the proteins as well as the rocky ones? Ian was pleased with this response. It was clever (at least in his own mind) and it sort of addressed the actual question.
