In almost all of royalty there are always politics, from everyone. George is a part of these politics. Not everything is happy and dreams you know. Heck the people don't always like their own monarchy.

Just let it slide for now. George will be a bit more respectful in the future, kinda. If he were alone with the queen then he would be more respectful, but with Mahzun around there is going to be some of this it's only politics
