Something about Aemond clinging to the Targaryen legacy, trying to get all of its attributes, including the world's largest dragon, but still having trouble controlling Vhagar. Something about the fact that Aegon, at the same time, denies everything related to his family, but has a dragon that obeys him naturally and intuitively, even when Aegon speaks English. Something about how it echoes the Iron Throne that Aemond craves so much, but that Aegon gets by birthright even though he doesn't want it.
