First of all I very much enjoyed your post as it was very detailed and clear. I completely agree with your view on the hierarchy upon this video as you can clearly see that the male blonde star representative possesses the most power. He controls the outcome and the conversation as you highlighted in your second question, the woman on the other hand just went along with the conversation and thanked him for all the "help". I can also understand from your post how modern sexism was used, as her looks were attributed to her intelligence and the representatives sex was matched to his stance of power.
Overall great post,
