Where the page and the screen part
Aegon the Younger's role in both tellings is largely confined to his parentage and his dragon rather than any independent action, and the two versions track closely on the facts available ÔÇö the differences that exist are chiefly matters of how much screen time and narrative attention the ongoing show chooses to give a character who, in the book, remains a minor figure throughout the war's main action.
Their journey
Where the two tellings send them to the same place the road runs whole; where they part, the screen keeps the left and the books the right.
