No way. Around the 2:30 mark The Duchess clearly is forcing herself to remember her manners (possibly hiding something?) whereas the Duke of Dinosaur is glad to be there and is having a good time, normally not being invited to such proceedings, what with representing the inferior dinosaur county and all.
Civility broke down, however, after conversation turned to the newly introduced bill in Parliament that would increase efforts to investigate new methods of mountain clearing at excavation sites across Britain. The Duke of Dinosaur had some fresh wounds reopened during those proceedings, and wished not to discuss it further.
