That's interesting because I heard and didn't see it. Over the radio, Horowitz was having trouble finding words of reply to Graham's "assault". Without body language, it sounded like he was caught unable to give a good answer - which could have been intentional, if that's the impression he wished to convey.

Horowitz was at times in those seven minutes not really looking for words. He had them right there but found himself not really wanting to interrupt Graham as Graham pretty much clearly laid it out...answering for Horowitz for the most part. It looked to me that Horowitz was amused (or pleased) that Graham was on a roll.
