Game Of Thrones Season 7: 9 Things You Might've Missed In 'Stormborn'
7. Balerion V Drogon
On the topic of dragons, and in getting to see the skull of Balerion the Black Dread (which Cersei shoots through the eye, a la Joffrey), we can now compare Drogon to Aegon's infamous beast, and there's not much in it now, even though Balerion lived for around 200 years,, and Drogon is about 6-years-old.
This fits with the words we overhear in the inn during the scene with Arya and Hot Pie, as one of the customers comments: "They say her dragons are bigger than Aegon's."
This same conversation also gives us another callback, this time to the wise words of Bronn (who still, sadly, hasn't appeared in Season 7 as yet). We hear the men discuss how they hope Daenerys lays siege to King's Landing, because prices will triple, and they want to get back there before it happens. Back in Season 2's Prince of Winterfell, Bronn said:
"The thieves, they love a siege. Soon as the gates are sealed, they steal all the food. By the time it's all over, they're the richest men in town."
