so I'm currently reading A Knight of the Seven Kingdoms and in The Mystery Knight, Egg tells Dunk that he has a dragon egg and so do his brothers and that his brother Daeron saw a dragon hatching in his dream. Egg, of course, wishes his egg to hatch, so he could fly just like the first Aegon.
Dunk, sceptical, replies something like "Yeah, and if all the knight in the realm died, I could be Lord Commander of the Kingsguard"
And I just know that Egg being the little smartass shit he is, he never lets Dunk forget that in the future.
Like, one random day in Kingslanding:
Egg/King Aegon V: Ser Duncan, I have good new and bad news...
Dunk: ...
Egg: Unfortunately, all the knight in the Seven Kingdoms has died.
Dunk: *panics*
Egg: Fortunately for us, that means you are the new Commander of the Kingsguard.
Dunk: Oh, you little shit...
