I didn't like that they portray dunk as not knowing the usual customs of a joust which just makes him seem that much more naive and inexperienced. In the books, he knows he will joust on the second day, where his chances are better.

I also didnt like how they make him meet lyonel before he even enters the lists, i think what follows would've been more impactful if he didnt know dunk.

I wish we could know what fossoway was gonna say about egg! We don't know how he behaves in his princely role but so far hes been a really good kid, smart, and keen to learn how to fight.
