The great thing I remember most from this moment is that he nuts away the ice, in mid conversation to his second. He's in conversation shouting down the route, and then heads away the ice with his hemet in a split conversational moment. So he goes quiet while he does it, but does it so normally and causually that it totally implies that he's done this a thousand times before. Perhaps even mid-conversation too.
